PREFACE
This Guidance Manual for state and local prosecutors was prepared
for the Noise and Radiation Enforcement Division of the United States
Environmental Protection Agency (EPA) as part of its mandate under the
Noise Control Act of 19721 to assist state and local noise control pro-
grams. The purpose of this Manual is to provide guidance to prosecutors
who choose to take legal action against violators of state or local noise
control regulations; its intent is to assist prosecutors preparing for
and conducting a trial—from drafting the complaint to submitting jury
instructions.
The Manual has as its point of departure the language of the EPA Model
Community Noise Control Ordinance (Model Ordinance); it does not attempt
to address each of the numerous and diverse ordinances in effect in many
jurisdictions. Drafted in 1975 by the National Institute of Municipal Law
Officers in conjunction with EPA, the Model Ordinance was intended to pro-
vide localities with a current and comprehensive model law to control
noise problems.
Chapter 1 briefly discusses the problems and effects of noise and
the technology of noise measurement. Chapters 2 through 5 outline the
major causes of action available under common law and the Model Ordinance,
describing in turn, common law and statutory public nuisance, property
line standards, motor vehicle controls, and tampering prohibitions.
For each of the causes of action addressed, the Manual provides details
on definitions, elements of the cause of action, types of evidence to
satisfy those elements, sample direct examination of witnesses, burdens

42 U.S.C.1 §4905 TTupp. 1978)

and order of proof, remedies, defenses, and special problems that may be
encountered in the course of prosecution.
Chapter 6, on forms and procedures, is a guide to drafting complaints,
motions, interrogatories, requests for admissions, depositions, discovery,
and jury instructions. Chapter 7 offers tips on pretrial and trial
technique, primarily through the use of question and answer scenarios
designed to establish essential points of proof, from the reliability
of sound level meters to the adverse health effects of noise.
Chapter 8 deals with a subject which, while outside the direct pur-
view of state and local prosecutors, may affect their decision to bring
legal action. It discusses the interaction between Federal and local
noise regulation and identifies areas where states and localities may be
preempted by Federal noise enforcement.
Where applicable, each chapter begins with the Model Ordinance pro-
vision relevant to the discussion following. Each chapter' also begins
with a concise summary of the issues and solutions presented in that
chapter.
Finally, the Manual provides a Glossary Of Key Terms and several
appendices of supplemental information, including the text of the Model
Ordinance, the Noise Control Act of 1972, and the Quiet Communities Act
of 1978.

CHAPTER 1: INTRODUCTION TO NOISE CONTROL
SUMMARY
People increasingly view exposure to excessive noise as a health hazard.
Although a number of major noise sources have been identified, the true dimen-
sions of the health effects of noise other than hearing loss are still uncer-
tain . Hearing loss, particularly if permanent, is one of the most serious
physical effects of noise on humans.
Noise may cause a range of physiological and psychological injuries. Noise
may trigger undesirable social behavior, and this effect may be increased with
physical fatigue. A number of close associations have been demonstrated between
cardiovascular diseases and noise exposures. Noise may also be a causitive agent
in other medical problems such as high blood pressure, col-itis, ulcers, and mi-
graine headaches. Furthermore, noise may have less obvious secondary effects in
addition to. its more direct-effects, for example, impairment of learning or job
performance and interference with other activities such as communication and
sleep.
Scientific and medical evidence may need to be brought to bear to prosecute
noise violators successfully. For that reason, the prosecuting attorney should
be familiar with the technical nature of sound measurement and the equipment
used to perform those measurements. Different types of noise measurements are
often taken for different types of activities, e.g., roadway noise and aircraft
noise. The time of day or night may also figure in the significance of these
measurements.
A sound level meter is the basic noise measuring device. Different meters
have different indicating characteristics and weighting network tolerances de-
pending on the sophistication of their circuitry.

-------
THE PROBLEM OF NOISE
In 1972, Congress declared a policy of promoting for all Americans an en-
vironment "free from noise that jeopardizes their health or welfare."^ The
House Committee Report2 recommending enactment of the Noise Control Act of 19723
noted that noise--unwanted sound—had a significant impact on more than 80 mil-
lion Americans; of that number, one-half risked serious health hazards from
exposure to excessive noise levels, primarily traffic and aircraft noise. About
21 million more Americans faced a similar problem with construction-related
noise. The Committee Report concluded that noise was increasing in urban areas
at such a pace that the average person's exposure would double by 1982. As for
what the public thinks about the problem, the Bureau of Census' 1977 Annual Sur-
vey found that Americans ranked noise as first-of all the undesirable conditions
of their neighborhoods.^
MAJOR SOURCES OF NOISE
In a 1977 survey, the Environmental Protection Agency (EPA) identified
vehicles such as motorcycles, trucks, and cars and construction activity of
various kinds as- serious noise sources.5 The survey ranked annoying noise
sources as illustrated in Tables 1-1 and 2.

EFFECTS OF NOISE
Although many of the health effects of noise are not yet clearly under-
understood or quantified, there is little doubt that noise can contribute to a
range of physical and psychological injuries. Even noise that may cause no
direct permanent physical health repercussions may still cause annoyance, sleep
loss, and other forms of mental distress.
Hearing Loss -- Hearing loss is the most quantifiable physical effect of noise
on humans. Sound enters the outer ear and initially reaches the eardrum, a
thin membrane protecting the middle and inner ear. The eardrum conducts sound
vibrations across the middle ear by way of the ossicles—three small bones re-
ferred to as the hammer, the anvil, and the stirrup because of their shapes.
Vibrations of the eardrum are passed mechanically to the inner ear by way of
the oval window separating the middle and inner ear- The principal parts of
the inner ear are the cochlea and the semicircular canals. The cochlea contains
fluid which is set into vibration by the movement of the oval window. Inside
the cochlea is a membrane to which are connected the roughly 30,000 hair cell
nerve endings whose shearing action upon fluid movement electro-chemically send
signals to the brain.
The ear's only protective device is the "acoustic reflex" which is a sudden
muscle contraction allowing the ossicles to lessen the impact of loud sounds
and thus protect the inner ear. This natural protective device is limited since
it functions best for low frequency loud sounds and since the reflex sound con-
tinues and is effective only at lower frequencies.
Hearing ability may vary based on age and sex. Women generally have better
hearing ability than men, possibly because men experience more occupational
noise exposure in their early and middle years. Hearing ability may decline
with age — called presbycusis.
-------
Loud noise can have an immediate effect on hearing and equilibrium.
Noise in the 135-140 dB range and above may produce actual pain and can damage
hair cells in the cochlea. Progressive loss of hair cells will result in a
progressive loss of hearing, frequently evidenced by the inability to detect
high frequency sounds. Noise is considered hazardous above 75 dB for 8-hour
exposures.
Temporary hearing loss caused by hair cell fatigue may result from long
term exposure to moderate or high levels. A temporary hearing loss stemming
from lower levels of exposure generally can be reversed if the ear is given
time to recuperate.
Non-Auditory Physiological Response to Noise
Noise may cause serious physiological effects on the human body which
range beyond deafness to enhanced risk of heart disease to adverse effects on
fetal nervous systems.
Noise acts on the body to produce stress. At approximately the 75-80, or
lower, decibel (dB) range, a number of short-term physical reactions take place
Heart rhythm and blood pressure changes occur, blood cholesterol levels rise,
pupils of the eye dilate, and stomach acid secretion may change leading to gas-
trointestinal malfunctions. Some automatic physical reactions such as blood
vessel constriction may continue for some period even after the noise stops.6
However, the extent of long term physiological effects is still not known.
The physiological effects on special populations such as the unborn,
children, the physical or mentally handicapped, and the aged who possibly may
be more susceptible to noise exposure is still under scientific scrutiny.
6 See generally, Environmental Protection Agency, Public Health and Welfare
Criteria for Noise, 7550/9-73-002 (1973).
-------
Social Impacts
Noise may trigger unpredictable psychological behavior- Because of their
subjective character, adverse psychological effects of noise are more difficult
to document than physical effects. Nevertheless, there is some scientific evi-
dence indicating that noise may increase irritability, argumentativeness, anxi-
ety, nervousness, and general aggressive tendencies, and decrease helping be-
havior.''
Noise sometimes appears to have a psychological impact on human conduct in
disproportion to the actual physical characteristics of the sound. Sounds that
convey distress or alarm, such as a patrol car siren or a fire engine bell, may
have greater psychological effects than sound associated with some advantage or
necessity, such as a lawn mower or a garbage disposal unit.^
Noise experts stop short of directly linking psychological effects of noise-
to clinical mental illness.^ Rather than claiming a direct cause and effect
relationship, some experts suggest that based on their studies of mental illness
and of psychological effects, noise may merely aggravate a pre-existing mental
condition. On the other hand, one study indicated higher rates of admission to
psychiatric hospitals among people living close to airports.^

-------
Actual hearing loss, especially in children, may also produce secondary
psychological effects, particularly if parents or peers equate impaired hearing
with low-level intelligence and attach a stigma to such impaired hearing. Hear-
ing loss creates additional emotional and psychological problems for adults as
we! 1.
Other Impacts
Sound loud enough to interfere with conversation or mental concentration
may have adverse secondary effects in the educational or work environment. For
example, reading and language development in school children may be impaired by
a noisy environment if a child is unable to distinguish certain sounds or if the
noise distorts speech. Distractive noise may reduce worker productivity and
even become a workplace safety hazard where noise prevents a worker from hearing
warnings of potential danger. Disturbing noise levels may also reduce the en-
joyment of recreational activities through communication interference.
Environmental Impacts
The physiological reaction of animals to noise is very similar to that of
humans. Hearing loss or damage to the auditory system is the best documented
physiological effect of noise on test animals. Experiments also show evidence
of change in the urinary, adrenal, and reproductive functions of animals under
certain noise conditions. Animals may even experience disruption of breeding,
nesting, and' migratory habits.
Noire and induced vibrations can adversely affect structural materials.
Cracked plaster and broken windows and dishware left in the wake of a sonic
boom are the best known examples of damage from excessive noise levels, but
they are not the only examples. Heavy construction equipment operation may
cause damage to neighboring structures. Noise induced vibrations can also
damage delicate scientific and health care instruments.
-------
Noise Measurement
There are three key variables in sound measurement: intensity; frequency;
and duration. The decibel (dB or dBA) is a unit for measuring the intensity of
sound. Its reference level is roughly that of the weakest sound audible to the
human ear at 1000 feet. The decibel scale is logarithmic, not arithmetic, so
that sound intensity multiplies by ten with every ten-decibel increase. In
other words, a 60 dB sound level corresponds to an intensity 1 million times
that of the sound pressure reference level. Similarly, a 60 dB sound intensity
is ten times that associated with 50 dB.
Since a pure decibel measurement reflects the intensity and not the "loud-
ness" human beings typically assign to various sounds, different scales or
weightings must be applied to the decibel level. Several weighting scales exist,
but most EPA noise criteria and standards are based on the A-weighting scale.
The A-weighting scale is a frequency-weighted scale which adjusts for the fact
that the ear does not respond equally to low, medium, and high range frequencies.
Different descriptors, conforming weighting with time and weighting fre-
quency content, are used in particular noise contexts: the long term equivalent
level (Leq), an A-weighted measure often used to measure roadway noise, gener-
ally over a 24-hour period; the day-night sound level (L(jn), a variation of
Leq which penalizes night time noise by assigning it a heavier weight (often
used in environmental impact statement evaluations); and two descriptors used
primarily to measure aircraft noise—the perceived noise level (Lp^j) and its
refinement, the effective perceived noise level (L^p^).
Description of Equipment
A sound level meter is the basic sound measuring device often used for
municipal noise measurement. The meter consists of a microphone, amplifier,
weighting scales (e.g., A-scale), and output meter. Meters may or may not have
-------
a graphic level recorder or a magnetic tape recorder, either of which can pro-
vide permanent documentation of noise levels. Meters may be hand held or mounted
on a tripod.
Different meters have different indicating characteristics and weighting
network tolerances depending on the sophistication of their circuitry. The four
different types of sound level meter instrumentation are: Type 1 (Precision);
Type 2 (General Purpose); Type 3 (Survey); and Type 4 (Special Purpose).11
Noise control ordinances typically specify only that the particular sound mea-
suring equipment used must meet standards set by the American National Standards
Institute (ANSI). However, calibration of the sound-level meter should also be
performed with instruments which meet ANSI standards. Manufacturer's specifica-
tions accompanying a sound level meter will indicate whether or not the instru-
ment meets these standards.
Measurements may vary depending on the source measured and on surrounding
conditions. Wind, humidity, temperature, and precipitation are critical factors
that also may affect the reliability of the readings. In measuring automobile
noise levels, the microphone location and general topography, including the pres-
ence of possible sound reflecting surfaces, are important to accurate measurement.

SUMMARY
The current trend toward a regulatory approach to noise abatement (e.g.,
Model Ordinance), has not meant abandoment of traditional common law (nonstatu-
tory) remedies for noise control. The public nuisance action continues to play
a significant role in noise control.
The common law or statutory public nuisance action is an effective vehicle
for controlling noise in several instances: 1) in jurisdictions where specific
maximum decibel levels have not been adopted; and 2) in cases unsuited to con-
trol through enforcement of maximum decibel levels, e.g., barking dogs, loud
parties, and other intermittent noises. To distinguish public from private
nuisance, Table II-l compares public and private nuisance actions at common law
and as they are now developing in modern statutory law.
A cause of action for common law public nuisance must establish: (1) that
an interference with a right common to the general public occurred; (2) that
the interference was unreasonable; and (3) that the public right was a substan-

tial one. Intent to harm is not an element, although it may be relevant to show
show whether the interference was unreasonable.
Scientific and medical evidence may be the most useful to show the unreason-
ableness and substantiality of interference. Lay testimony about the annoying
characteristics of noise may not of itself support a finding of public nuisance.
A cause of action for statutory public nuisance requires evidence of a stat-
ute prohibiting the noise nuisance and proof of the violation.
The prosecutor carries the burden of proof by a preponderance of the evidence
except where a jurisdiction characterizes public nuisance as a criminal offense.
In the latter case, each element must be proved beyond a reasonable doubt.
Injunctive relief is one of the most important remedies appropriate to a
noise nuisance action because if granted the nuisance is stopped, either perma-
nently or at least temporarily during litigation. The prosecution can anticipate
a number of defenses, including business necessity, compliance with administra-
tive regulations, cost of abatement and, in certain cases, Federal preemption.
For the most part, however, these defenses are neither absolute nor sufficient
to block a well-founded noise nuisance prosecution.
COMMON LAW AND STATUTORY DEFINITIONS OF PUBLIC NUISANCE.
At common law, a public nuisance was a "criminal interference with a right
common to all members of the public."^ It was considered a criminal offense
and encompassed a diversified group of minor offenses against the public peace,
morals, safety and health—from harboring a barking dog to operating a noisy
dance hall .2

2 Restatement (Second) of Torts §8218, Comment b, at 88 (Tent. Draft
No. 17, 1971).
13
-------
The inherent vagueness of the "crime" of public nuisance has led to several
changes in the law defining that offense. The first change was to codify the
common law crime in state statutes. That development brought on two more recent
trends: First, the replacement of broad and ambiguous statutory public nuisance
provisions by a series of more specific laws declaring certain specific actions
to be public nuisances and, as such, crimes; second, a shift toward characteriz-
ing public nuisances as civil offenses.3
Modern trends in public nuisance law have not diminished the usefulness
of this cause of action as a tool for state and local officials to combat noise
The concept of public nuisance as a tort action—rather than an action
in criminal law—has been accepted by the American Law Institute. Ac-
cording to the Restatement (Second) of Torts §8218 (Tentative Draft No.
17, 1971):
* A public nuisance is an unreasonable interference with a right common
to the general public.
* Factors conducting toward a determination that an interference with a
public right is unreasonable, include the following:
a) The circumstance that the conduct involves the kind of
interference with the public health, the public safety,
the public peace, the public comfort or the public con-
venience which sufficed to constitute the common law
crime of public nuisance;
b) The circumstance that the conduct is proscribed by a
statute, ordinance or administrative regulation; or,
c) The circumstance that the conduct is of a continuing
nature or has produced a permanent or long-lasting ef-
fect upon the public right, is substantial, and in con-
nection with which the actor knows or has reason to
know of the effect.

violations.4 Even at common law, a public nuisance could often be remedied
by civil injunctive relief as well as by criminal sanctions. In those cases
where conduct clearly falls within the scope of a criminal provision, the
prosecutor may well find the more effective strategy to be one of quick abate-
ment of the noise violation through injunctive relief rather than resort to
criminal sanctions against the violator under the more stringent criminal
burden of proof. If the criminal provision does not expressly authorize in-
junctive relief as a remedy, the common law of public nuisance provides the
needed authority.^
ELEMENTS OF THE CAUSE OF ACTION
Common Law Public Nuisance
To prove an action for public nuisance, the following elements must be
established:
* That an interference with a right common to the general public
occurred;
4 Public nuisance actions to control noise have been maintained against
a variety of sources: Harrison v. Indiana Auto Shredders, Inc. 528
F.2d 1107 (7th Cir. 1975) (automobile shredding and recycling plants);
Firth v. Sherzberg 336 Pa. 443,77 A.2d 443 (1951) (truck terminals);
Yanderslice v. Shawn 26 Del. Ch. 225, 27 A.2d 87 (1942) (aircraft
overflights).
Private nuisance actions have been maintained against a series of
other noise sources which presumably could have been prosecuted as
public nuisances had they affected a wider population. These include:
Friedman v. Keil, 113 N.J.Eq. 37, 166 A. 194 (1933) (bakery noise);
Proulx v. Busbanes, 354 Mass. 559, 238 N.E.2d 531 (1968) (laundry &
drycleaning plants); Braddock v. Barbecue Cottage, Inc., 69 Dauph.
Co. (Pa.) 221 (1956) (fast food restaurant); Guarina v. Bogart, 407
Pa, 307, 180 A.2d 557 (1962) (drive-in theater); State ex. rel- Towle
v. Eyen, 130 Neb. 416, 264 N.W. 901 (1936) (tavern); Gustafson v.
Cotco Enterprises, Inc., 42 Ohio App. 2d 45, 328 N.E.2d 409 (1974)
(racetrack); State ex. rel. Fuller v. Stillwell, 114 Kan. 808, 220
P. 1058 (1923) (barking dog).
5 Restatement (Second) of Torts §821B (Tent. Draft No. 17, 1971).

-------
* That the interference was unreasonable; and
* That the public right was a substantial one.
A right common to the general public is one that affects an entire commun-
ity rather than one or a few individuals. Both the unreasonableness of the
interference and the substantiality of the right interfered with are defined by
using the reasonable person standard.6
Intent to harm is not an element of the public nuisance cause of action
because a violation exists if certain conduct is prohibited by statute. Never-
theless, intent is relevant to show whether the interference was unreasonable.
Under general tort law principles, interference with a public right may be con-
sidered unreasonable if the conduct is intentional, negligent, reckless, or
involves abnormally dangerous activites. On the other hand, in actions for in-
junctive relief, intent or knowledge is less persuasive because injunctions are
granted when: (1) no adequate legal remedy exists; (2) irreparable harm otherwis.
will ensue; (3) the court finds that ordinary legal principles would not afford
relief.
Statutory Public Nuisance
To satisfy the elements of a cause of action for statutory public nuisance,
the prosecutor must establish the existence of a statute prohibiting the noise
nuisance and prove that the defendant violated the statute. Under some noise
5 The Restatement (Second) of Torts lists a number .of factors tending to
substantiate a claim that an "unreasonable" interference has occurred. See
footnote 3, supra. However, this list is not all inclusive. As the Reporter
of the Tentative Draft noted in comment e, some courts have recognized inter-
ference with aesthetic values or with established principles of conservation
of natural resources as amounting to a public nuisance.
16
-------
nuisance statutes, neither the unreasonableness of the noise nor the intent to
interfere with a public right are elements of the offense.
Under those state statutes modeled after the Model Ordinance or the common
law, however, the unreasonableness of a noise nuisance may still be an element
subject to proof requirements.
Under Model Ordinance-type language, the prosecutor need not prove criminal
intent. Again, however, intent would be relevent to the unreasonableness of
particular conduct. Where it is unclear whether a particular state statute re-
quires a showing of criminal intent, case law supports the view that the nces-
sity of proving intent depends on the nature of the case.''
TYPES OF EVIDENCE TO SATISFY BURDEN OF PROOF
To satisfy the burden of proof on the three elements of a public nuisance
action, the prosecutor most likely will need to rely on some combination of lay,
scientific, and medical testimony.
Lay evidence will be helpful in proving the unreasonableness and substan-
tiality of interference. The standard applied is that of the reasonable person.
However, a noise prosecution may also rely heavily on certain types of scientific
and medical evidence.
Scientific Evidence
Scientific evidence may consist of:
* Expert testimony by acoustical engineers;
* Sound measuring devices;
* Noise measurements;
* Tape recordings of the noise;
* Graphs comparing decibel levels;
66 C.J.S. "Nuisances" §10 (1950).
17
-------
* Maps indicating the location of the noise, including distinc-
tions between residential and industrial zoned areas.
Recordings by sound level meters, and other sound measurements are import-
ant pieces of scientific evidence to use to demonstrate that a particular noise
level constitutes a health threat. Seldom will statements from members of the
public about the annoying characteristics of the noise be sufficient of them-
selves to support a finding of public nuisance.8 Rather, the prosecutor must
attempt to show that the noise at issue created a threat or hazard to the health
or safety of the community.
Local procedural rules and practice may indicate whether local courts have
taken judicial notice of the reliability of sound measuring devices or whether
they require an offer of proof. However, proof must be offered' that the sound
meter actually used in a noise test functioned properly at the time the critical
reading was taken. This can be established through the use of expert witnesses
or the operator of the machine to establish that:
* The device was functioning properly at the time of the reading;
* The operator was competent to operate the machine;
* The recording was authentic and correct; and
* Calibration of the equipment itself was made proximate to the
time and place of the noise.9
8 See_ Harrison v. Auto Shredders, Inc., 528 F.2d 1107 (7th Cir. 1975) (trial
court reversal because there was no competent evidence offered to demonstrate
that the operation of a noisy automobile shredding and recycling plant was a
public nuisance).
9 U.S. Noise Enforcement Division, Environmental Protection Agency, State and
Local Hornbook (Draft, May 1, 1978).
18
-------
It may also be necessary to introduce evidence of a continuous chain of
custody record showing the equipment used for the sample, the time, the date, the
name of the person taking the measurements, and the custodian of the record.10
(All data should be recorded in ink at the site.)
Medical Evidence
Medical evidence may consist of:
* Expert testimony by a physician, audiologist, psychiatrist,
or other appropriate health professional;
* Medical records;
* Medical charts.
Loss of hearing and damage to the auditory system are serious injuries
caused by excessive noise. Although the medical and scientific communities are
not in agreement about the exact physiological effects of noise on the body,
there is strong evidence suggesting a link between continuous noise exposure and
the development of heart disease.H Noise may also cause stress reactions such
as nervous tension and irritability from lack of sleep.
The best method for proving psychological stress is to have both the com-
plaining witness and a psychiatrist testify. Medical testimony is appropriate
to prove injury. For example, in a case involving a hearing loss, a medical
expert should be called to testify on the nature of the injury, the proximate
cause of injury, and the likelihood of recovery.

-------
BURDEN AND ORDER OF PROOF
Burden of Proof
The burden is on the prosecutor in a public nuisance action to prove each
element of the offense. Under the Model Ordinance and other noise control stat-
utes that have removed the element of criminality from the concept of public
nuisance, each element must be proved by a preponderence of the evidence. In
jurisdictions that maintain the concept of public nuisance as a criminal offense,
each element must be proved beyond a reasonable doubt.
Order of Proof
Although some types of evidence may not be necessary in a particular nui-
sance case, the following is the suggested order of proof for a nuisance case.
* PHYSICAL FACTS -- Proof of the location of the source of the noise;
receptor; types of activities conducted in the area; structures; and
the topographic and geographic characteristics.
* SCIENTIFIC FACTS -- Nature of noise and the effect on the public health,
safety, or peace.
* MEDICAL FACTS -- Testimony and exhibits demonstrating a public health
hazard.
* PROPER MEASUREMENT TECHNIQUES — Testimony by expert witnesses on
noise measurements taken.
* SOURCE -- Evidence to establish and prove the source of the noise and
to identify the party in control of the source.
* UNREASONABLENESS AND SUBSTANTIALITY — Evidence that the noise emanat-
ing from the source was unreasonable and that it substantially inter-
fered with the community's health, safety, peace, comfort, or conveni-
ence. (Witness testifying to a nuisance.)
20
-------
* REMEDIES -- Proof of facts necessary to substantiate the request for
appropriate remedies. Proof of imminent and irreparable injury should
accompany requests for injunctive relief. Justification for amount
and duration should accompany requests for court imposed fines.
REMEDIES
Injunctive Relief
An injunction requiring a defendant to abate a noise nuisance remains one
of the most important remedies available in a public nuisance action—regardless
of whether the conduct is considered a crime or a tort.
Section 11.4(a) of the Model Ordinance suggests that where the enforcement
officer has the power, the first line of offense in a noise pollution case
should be an administratively issued compliance order and injunctive relief.
The traditional equitable requirements of proof of imminent and irreparable
harm, and an inadequate remedy at law apply in noise nuisance cases where injunc-
tive relief is requested just as they would in any other proceeding for injunc-
tive relief.12
Traditional Criminal Remedies
Under circumstances where the defendant takes advantage of the possibility
that the cost of abatement may be more than the cost of compliance with a re-
straining order, criminal sanctions may be necessary to achieve compliance.
Fines are the most frequently imposed criminal.sanctions under such circumstances
Damages
Damages rarely are sought or recovered in a public nuisance noise action.

-------
DEFENSES
The following defenses are available in public nuisance actions,
but offer limited opportunities for success:^
* Exhaustion of administrative remedies
* Compliance with statutory control; conformity to regulations issued
by an administrative agency or conformity to a permit or license.
The following defenses generally are not available in public
nuisance actions:14
* Statute of Limitations
* Laches
* Estoppel
* Prescriptive rights
The following defenses may be available in particular cases:
* Business Necessity - Business necessity traditionally has not been an
effective defense.15 in most cases, however, business necessity may
carry some weight if the court is persuaded that the value of continued
operation of the business outweighs the harm suffered by the plaintiff.
* Cost of Abatement - The cost of abatement generally will be one of the
elements considered by a court if asked to grant injunctive relief.
The defendant is more likely to be persuasive in arguing against such
13 See 58 Am Jur 2d, "Nuisances" §§157, 234 (1971); Schofield v. Material
Transit, Inc., 206 A.2d 100 (1960) (existence of remedy before Air Pollution
Board does not of itself oust court of chancery jurisdiction, but primary
judicial relief may not be applied for when there are administrative remedies
pending).
14 See 53 Am Jur 2d, "Nuisances" §§167, 168, 225 (1971).
15 See Cat!in v. Patterson, 10 N.Y. 724 (1887).
22
-------
relief if the cost of abatement is so severe that it would put the de-
fendant out of business, or jeopardize the prosperity of the community.-'-5
* Coming To The Nuisance - In a majority of jurisdictions, the fact alone
of "coming to a nuisance" (i.e., locating in the vicinity of an already
existing nuisance) is not an absolute defense or estoppel. However,
this factor may be relevant in determining whether the defendant's use
of property is unreasonable. While some courts will permit a person
who purchases land or moves into the vicinity of a nuisance to seek
damages or an injunction against the nuisance,1'' other courts will deny
relief if the plaintiff knew that a nuisance existed at the time of
purchase or if the plaintiffs obtained the benefit of the reduced value
for their property.^
* Negligence - Contributory negligence is no defense when the defendant
intentionally has created a nuisance with the knowledge that it will
m
interfere with the plaintiff's use and enjoyment of the land. However,
some states do allow this defense to be used in nuisance actions not
involving intentional or malicious conduct. The courts reason that a
nuisance can be negligently created; therefore, contributory negligence
16 See Am Jur 2d, "Nuisances" §215 (1971).
17 Annot., 42 A.L.R. 3d 344, 346 (1972). As the court observed in
Vowinckel v. N. Clark & Sons, 216 Cal. 156, 13 P. 2d 733 (1932): "The fact
that a plant had municipal consent and that its operations were conducted
in an industrially zoned area, or that it had operated for 17 years jefore
the plaintiff purchased and established his home there, did not constitute
a defense to the continued operating of the plant in such a manner as to
constitute a nuisance to the plaintiff."
18 id. In at least one case a court has held that purchasers of land who have
knowledge of the existence of damaging structures will not thereafter be
allowed to recover for any damages to the land, since they are presumed to
have obtained the benefit of reduced value by the amount the prior owner
could have recovered. See W. Prosser, Law of Torts 609 (4th ed. 1971).
23
-------
may be valid defense. Assumption of the risk or consent to take
the risk may also bar the plaintiff's recovery in a noise nuisance
action.19
* Parties [Joint-Tortfeasors; Single Individual Injury Rule] — A
noise violation may have been created by more than one defendant.
Since it may be almost impossible to determine which defendant
caused the most damage, the majority of jurisdictions are likely
to hold each defendant liable, under the "single, indivisible
injury" rule.
It is not a defense for individual defendants to claim that the
noise they released would not by itself have caused the noise
problem, nor is it a valid defense for them to claim that indivi-
dually each released noise at different times or places.20
* Legislative Authorization -- In some jurisdictions, conduct which
otherwise would be considered a public nuisance may be authorized
by the legislature, subject only to due process limitations.
Generally, courts will construe narrowly any statute that authorizes
the creation or maintenance of a nuisance. This strict scrutiny
may also be extended to a review of the specific grant of authority
19 W. Prosser, Law of Torts 609 (4th ed. 1971). In the majority of juris-
dictions, the rule of avoidable consequences is available not. as a defense,
but in measuring damages. According to this doctrine, the plaintiff may
be required to take reasonable steps to guard against further harm.
20 B. Cohen, V. Yannacone and S. Oavison, Environmental Rights and
Remedies § 6.15 (1972). ("Where two or more independent tortfeasors
have supplemented each other's actions and concurred in_contributing
to and producing a single indivisible injury to the plaintiff, the
independent tortfeasors will be regarded by the law as joint tort-
feasors, jointly and severely liable to the plaintiff, though there
hasn't been concerted action among tortfeasors.

-------
given to a particular administrative agency. Legislative authority may
be a defense against injunctive relief barring operation, but the fact
that a business is being conducted properly as defined by legislative
or administrative action does not necessarily preclude recovery of
damages.21
* Preemption — The Model Ordinance, section 11.6, retains common law or
statutory rights of action. Preemption may be a sufficient defense in
limited circumstances where the Federal Noise Control Act of 1972 has
partially preempted regulatory authority over an area as, for example,
rail road noise.22
* Primary Jurisdiction -- There may be jurisdictions that have adopted an
administrative approach to the enforcement of environmental laws,
vesting exclusive jurisdiction over such matters in an administrative
agency. Opinion is divided on whether this would preclude maintenance
of a common law or statutory public nuisance action sounding in criminal
law. Primary jurisdiction is not a defense in jurisdictions that have
adopted the Model Ordinance.23

-------
SUMMARY
The Model Ordinance's property line noise control scheme is based on
references to both receiving land use categories and by time of day, a feature
not always present in local noise ordinances. Receiving land use categories
usually are based upon the following zoning classifications: open space, pub-
lic space, agricultural, residential, institutional, commercial, or industrial.
See Table 1-1, supra.
Essentially, the prosecutor of a property line violation must show that:
1) the defendant was responsible for a noise source on private property; 2) the
noise level was above permissible levels for the period of day or night; and 3)
the noise level was above that permitted for particular receiving land uses.
It may be necessary to establish the validity of sound level meter evi-
dence in a property line case. Some courts take judicial notice of such evi-
dence; others require that experts testify with regard to the type and model
of sound level measuring devices used in the jurisdiction.^-
Because the expert testimony of the police or noise control officer moni-
toring the' noise level on the property is so significant in property line cases,
this chapter offers a checklist of what the officer's testimony should describe,
as well as sample questions aimed at establishing the reliabilty of the sound
level measuring tests.
Proof by a preponderance of the evidence is the typical standard of proof.
Remedies available for a property line standards violation include fines, in-
junctive relief, abatement orders, and an order for corrective action.

-------
Certain procedural, technological, and substantive arguments can be antici-
pated as defenses, including claims that the officer had no authority to enter
private property, that the sound level measurement was incorrect, or that some-
one other than the party charged operated the noise source.
ELEMENTS OF CAUSE OF ACTION
To successfully prosecute an action for violation of property line noise
standards the prosecutor must establish that statutory provision exists and
that it was violated. The prosecutor must be able to prove that:
* The defendant operated or caused to be operated on private property
a source of sound;
* The noise exceeded the sound level limits established for the par-
ticular time of day or evening; and
* The noise exceeded the sound level set for the receiving land use
category when measured at or within the property line.
TYPES OF EVIDENCE TO SATISFY ELEMENTS
•
Scientific Evidence
A property line standards case may require the use of competent scientific
evidence ranging from the expert testimony of noise instrument experts to data
from sound measuring devices.
Establishing the Validity of Sound Level Meter Evidence -- In jurisdictions
where courts have not taken judicial notice of the validity of sound level
meter evidence, a court may require expert testimony regarding the scientific
validity and accuracy of the measuring device itself-2 Experts may be asked
to testify specifically about the accuracy of the type and model of sound level
measuring device used in the particular jurisdiction.
2 See Annot., 47 A.L.R. 3d 822, 827, at n.4 (1973!
28
-------
In all cases, whether in courts taking judicial notice of sound measuring
devices or in courts where no such notice is taken, the prosecutor should dem-
onstrate that the particular equipment used in detecting the noise violation
was of the required type, in proper working condition, and was operated by a
qualified individual.3
One source for expert witnesses may be the manufacturer of the measuring
device used. If the manufacturer also services the device, the testimony of
the service expert should be sought on the question of the reliability and ac-
curacy of the measuring equipment. In all cases, the qualifications of the
expert witness first must be established. (See Chapter 7, Trial Techniques,
(Qualifying Experts).
Testimony of the Officer Monitoring Sound Level Meter
The expert testimony of the police officer or noise control officer who
.took the on-site sound level measurements is perhaps the strongest evidence
that can be presented in most property line standards cases. That testimony
should describe:
* The equipment used to monitor the sound level, including informa-
tion identifying the manufacturer, model and serial number, and dates
of last laboratory or factory calibration according to manufacturer
and A.N.S.I, standards;
* A field calibration of the equipment, for proper operation and accur-
acy, made on the day the particular property line noise violation data
was recorded.
* The location of the measuring device at the time of the alleged
violation;
* The officer's steps in setting up the equipment according to the noise
control regulations in effect, the day the noise violation measurement
was made;

29
-------
* The weather conditions (e.g., wind speed, precipitation), or other
unusual condition, including ambient noise level that would affect
the noise level reading;
* The details of the violation including a sketch or diagram of the
general site, a description of the noise source, and a description
of the receiving land use (i.e., residential, commercial, or indus-
trial);
* The actual measurements taken of the noise source, recorded in ink
if done by hand.
The results of sound level measurements should be introduced into evi-
dence, along with charts, maps, and photographs of the noise source.
Sample Questions for the Officer Operating Sound Level Meter
After qualifying the officer, the prosecutor should ask questions designed
to establish violation of a property line standard. Sample questions follow:
Q. Describe the property line standards that exist in this jurisdiction
for [residential], [commercial I, or [industrial] land use-categories.
Q. Did you take a noise level reading at [site] on [date]?
Q. At what time did you take the reading(s)?
Q. What was the exact reading of the noise level?
Q. Is that a violation of [jurisdiction] noise ordinance levels
for [category] of receiving land use?
Q. By how many dBA?
Q. What is the significance of this difference?
The following line of questioning aims to establish the technical
reliability of the sound level meter.^
Q. Describe the sound equipment used to measure the sound level

Q. What type and frequency of calibration is performed on this
equipment to ensure its accuracy [field calibration and system
calibration by certifying laboratory]?
Q. Was this equipment set up and located according to procedures

Q. Was the equipment tested for accuracy on the date of the ob-
served violation? If so, how? [Answer desired is that a daily
fixed field calibration was done at setup, and a system calibra-
tion was certified no more than 6 months earlier].
Q. Was (were) the test(s) satisfactory?
Q. Were the results recorded?
Another series of questions should be aimed at establishing the relia-
bility of the sound level measuring tests by eliminating possible extraneous
influences. For example:
Q. Describe the set up procedure you used in setting up the sound level
meter [mounting procedures, distance from noise source, use of wind-
screen, height and positioning of microphone, and other relevant
factors].
Q. Did you hear any other noise sources that could have caused an erron-
eous reading?
Q. Were there any reflecting surfaces near your monitoring location
that would induce an error in your reading?
Q. What were the weather conditions?
Q. At what distance from the property line was the sound meter reading
taken?
BURDEN AND ORDER OF PROOF
The burden of proof in a civil case is proof by a preponderance of the
evidence. If a criminal remedy is sought, the burden is proof beyond a
reasonable doubt. The following is the suggested order of proof, beginning
with the topographic and geographic features of this site:
* Physical Facts - The location of the noise source, and receptor;
the type of activities conducted in the area; and the structures
(buildings) present;
31
-------
* Source - Evidence should be entered to establish and prove the
source of the noise and its connection to the defendant;
* Proper Measurement Techniques - Expert witnesses should be called
to testify about what noise is and how sound level measurements
are taken;
* Violation - Evidence of statutory or common law provision and a
violation of such provisions is essential;
* Remedies - Appropriate remedies should be requested and substantiated
by necessary justifications. For example, a request for injunctive
relief should be accompanied by proof of immediate and irreparable
harm. Requests for fines should specify the amount and duration of
the fine and should otherwise justify such relief. (Fines, if appro-
priate, usually are spelled-out in the relevant ordinance.)
REMEDIES
Remedies available for a property line standard violation include fines,
injunctive relief, abatement orders, and an order for corrective action.
An injunction is a suitable remedy for a violation of property line stan-
dards. For guidelines to show an immediate threat to health and welfare of cer-
tain sound levels in extreme cases, the prosecutor may wish to refer to Tables
IV and V of Article XI of the Model Ordinance.
DEFENSES
A number of procedural, technological, and substantive arguments may be
asserted as defenses to prosecution for violation of a property line ordinance,
typically to no avail, however-
Procedural Defenses
Procedural omissions such as failure to obtain valid authorization to
enter private property where necessary, or failure to preserve the chain of
custody for evidentiary materials, could prompt a successful defense challenge.
Technological Defenses
The defense may attack the validity of the prosecutor's sound level mea-
surement evidence on cross-examination or present its own opposing expert tesi-
32
-------
mony. The defense may challenge, for example, sound level readings taken under
atypical physical and environmental conditions.
Substantive Defenses
A property line case which directly contests the existence of a violation
is the easiest challenge. Defense counsel may suggest that the wrong party was
charged with the violation, and question the correctness of the noise source
identification. If the site is a multiple unit dwelling or a business complex,
the proper party must always be identified. Defenses based on local zoning pro-
tection for pre-existing uses, variances, and non-conforming use exemptions
also may be raised in a property line standards case.

SUMMARY
Section 9.1 of the Model Ordinance is aimed at controlling the noisy opera-
tion of motor vehicles and motorcycles on public streets. What the prosecutor
must show in such cases is proof that the defendant was operating a vehicle that
emitted noise in excess of proscribed limits. Testimony of the apprehending
officer along with scientific evidence likely will play a major role in this
offer of proof. Not all courts will take judicial notice of the reliability of
sound measuring devices, in which case a foundation must be laid. In all cases,
however, courts will want some proof that the particular monitoring equipment
used was proper and in proper working condition and that the person using it
was a qualified operator.
This chapter outlines a series of questions designed to establish proof of
a motor vehicle violation and proof of the reliability of the sound level meter.
It also details the types of information that could be asked of the apprehending
officer, if that individual is someone other than the monitoring officer.
Either the civil (preponderance of the evidence) or criminal (beyond a rea-
sonable doubt) standard of proof will apply, depending on how the particular
jurisdiction defines a motor vehicle noise violation. Remedies range from notice
of violation, to abatement orders, to penalties. Lack of notice, as in radar
cases, may be a viable defense in some jurisdictions.
ELEMENTS OF THE CAUSE OF ACTION
In order to successfully prosecute a motor vehicle operator, the prosecutor
must be able to show that:
* The defendent operated or caused to be operated a motor vehicle
or motorcycle on a public right-of-way; and
* The motor vehicle or motorcycle was operated in such a manner
that the sound level emitted exceeded the limits established
in- the ordinance.
35

TYPES OF EVIDENCE TO SATISFY ELEMENTS
Scientific Evidence
As with prosecutions for exceeding permissible receiving land use sound
levels (see Ch. 3), scientific evidence may play a major role in motor vehicle
noise violation cases.
The use of objective sound level standards and sound level meters to en-
force motor vehicle noise standards has not been challenged extensively in
court. However, sound level meters used in noise enforcement are similar to
radar speedmeters used in speed limit enforcement. As an analogous technology
and mode of enforcement, the legal development of radar speedmeter readings
as admissible evidence should prove highly supportive in the development of
case law involving the use of sound level meter readings as evidence.1
Establishing the Validity of Sound Level Meter Evidence
When data secured by the use of sound level measuring devices are placed
in evidence to show violation of objective noise limits, as in the case of
radar speedmeter data to show violations of speed limits, a court may require
expert testimony on the nature and function of sound level measuring devices
and the scientific principles upon which they are based.2
Before offering testimony regarding the scientific validity and accuracy
of the sound level measuring device, a foundation is laid through establishing
the qualifications of the witness. (See Chapter 7, Trial Techniques, infra.
This testimony constitutes the first part of the foundation necessary
before evidence produced by sound measuring devices may be admitted in court.
1 See Annot., 47 A.L.R. 3d 822 (1973) (admissibility of radar speedmeter
evidence); see also, Chapter 3, note 1, supra.
2 See discussion Chapter 3, Property Line Standards, supra.
3-6
-------
In courts where judicial notice of sound measuring device reliability has been
taken, this step may not be necessary, but the prosecutor must be able to demon-
strate in all cases that the particular equipment used was of an appropriate
type and in proper working condition, and that the person using the device was
qua!ified to do so.3
Testimony of the Officer Operating Sound Level Meter
The testimony (after qualification) of the officer who monitored the
sound level measuring device should describe:
* The equipment used;
* The system calibration procedure performed by a certifying
laboratory to assure accuracy and proper operation of the
equipment;
* The field calibration of the equipment for proper operation and
accuracy, made on the day the particular measurement for which
defendant was charged with exceeding the noise limits;
* The location of the monitoring device;
* The officer's procedure in setting up the equipment according to
the regulations in effect in the jurisdiction on the day the
particular measurement for which defendant was charged with
exceeding the noise limits was made;
* Any environmental conditions that would affect the noise level
reading and any corrective measures taken, e.g., use of wind
screen.
* A description of the vehicle involved in the alleged noise ordinance
violation, including its color, make, and license number;
* The recorded sound level emitted by the defendant's vehicle
at the time it was monitored, as shown by the sound level
meter;
* The conveyance of pertinent information regarding identity of
the offending vehicle and noise level reading to the appre-
hending officer, where the monitoring officer is not the same
individual as the apprehending officer.

Sample Questions for Officer Operating Sound Level Meter
After qualifying the officer, the following sample questions may help es
tablish a violation.
Q. Describe the noise level standards that are enforced
in this jurisdiction.
Q. At about [time] on [date] did you observe a [color and
make of vehicle] with [state] license number
near [location]?
Q. In what direction was it traveling?
Q. In what lane?
Q. Did you obtain a noise reading of this vehicle?
Q. What was that reading?
Q. Is that in violation of [jurisdiction] noise ordinance
levels for vehicles of that class?
Q. By how much?
Q. What is the significance of this difference?
Q. What did you do after you noted the apparent violation on the
the sound level meter?
[Give testimony regarding observation of vehicle, recording of color,
make, license number, other identifying particulars, and of notifying
officer in apprehending vehicle by radio.]
Q. Did you observe officer [give name] give chase and
apprehend this vehicle?
Q. When you noted the apparent violation, were there any other
vehicles in the measurement zone?
Q. Did you note any other noise sources that could have
caused an erroneous reading on the vehicle in viola-
tion?
Q. Were there any reflecting surfaces near your monitor-
ing location that would induce an error in your
reading?
Q. What was the ambient level observed at that time?
38
-------
Q. Is this level more than (6dBA/10dBA)4 below your enforce-
ment level?
Q. Why is this difference significant?
[Give testimony to explain the relevance of ambient noise levels to
enforcement monitoring readings. An ambient level of 10 dBA less
than the maximum permitted ordinance level would add less than .5 dBA
to the reading if the vehicle emitted noise at the maximum permissible
level. An ambient of more than 10 dBA below the maximum would con-
tribute even less and would be functionally negligible in the total
reading.]
Q. Describe the sound measuring equipment used to record the noise
level.
Q. Where was the equipment located when you measured the
noise?
Q. Describe the procedure for sound level meter set up.
[Give testimony relating to mounting procedures, distance from
traffic, use of windscreen, height of microphone, angle of micro-
phone to traffic, and other relevant factors.]
Q. Was this equipment set up conducted in accordance with
the criteria established in [cite relevant provisions
from regulations or test procedures manual"!?
Q. What do your regulations require as to factory and field
calibration of the equipment?
Q. How did-you meet these requirements?
It may be helpful to supply the document which certifies the most recent
calibration by the manufacturer and the field report which documents the field
calibration. It may also be good strategy to show the judge the equipment and
its dynamic range to illustrate the ease of interpretation of the noise reading
observed.
Testimony of the Apprehending Officer -- The apprehending officer should be
called to testify to facts within his or her own knowledge relating to flagging
4 There is a variation among jurisdictions as to the maximum ambient
level permissible at the time of vehicle monitoring—from 6 dBA to
10 dBA below the enforcement level.

-------
down the vehicle and to issuing the "ticket" or summons. (If the monitoring
officer and apprehending officer are the same person, the sample questions
presented on the preceding pages of this Manual should suffice.)
The testimony (after qualification) of the apprehending officer at a
minimum should show:
* Communications from the monitoring officer relating to the offending
vehicle and its driver, including a description of the alleged
violator and the color, make, and license number of the alleged
violating vehicle;
* Conversations with the defendant pertinent to the excessive
noise charge, especially those showing defendant's reaction to
information obtained from the monitoring officer and repeated
to the defendant.
Sample Questions for Apprehending Officer
Q. At about [time of offense] on [date of offense] did you
issue a citation to (.operator "of~offending vehicle],
operator of a [co1or~a"nd make of vehicle] with [state]
license numberTnumberJ?
Q. Can you now identify that person to whom you issued the
citation? Please point out the individual in this courtroom.
Q. Can you describe the events leading to the issuance of
the citation?
Q. What did you say to the defendant at the time you issued the
citation?
Q. Did you conduct a visual inspection of the exhaust
system of this vehicle?
Q. What did you observe?
Q. On visual inspection of the equipment of this vehicle's
exhaust system, was there any doubt in your mind that
this vehicle was the source of the noise observed in
violation?
Q. Did you then issue a citation to the defendant driver?
On a finding of guilty, and if local procedures permit, it may be advisable
to move that the defendant be granted a reasonable period of time in which to
correct the malfunction and to have it tested.

BURDEN AND ORDER OF PROOF
Burden of Proof
In order to gain a conviction under this provision in jurisdictions that
treat violations as criminal actions, each element of the offense must be proven
beyond a reasonable doubt.5 Otherwise, the civil standard of proof (preponder-
ance of the evidence) applies.
Order of Proof
The suggested order of proof follows the order of testimony to
the effect that:
* The sound level measuring device was properly set up;
* The sound level measuring device was working and the meter
reading was accurate;
* The sound level measuring device and apprehending vehicle were
in sight of each other but separated by a reasonable distance
(in jurisdictions where this is required);
* Calibration tests for accuracy of the sound level measuring
device were made;
* The sound level meter operator had seen and heard the suspect
vehicle;
* The proper defendant was apprehended and given the "ticket", the
notice to appear, and the summons.
REMEDIES
Potential remedies available for violations of motor vehicle noise pro-
visions include notice of violation, abatement orders, and penalties. For
specifics, _see Model Ordinance, Article XI, Enforcement [Appendix C].
DEFENSES
Prosecutors can expect several defenses to be raised in a prosecution for
violation of a noise control ordinance provision relating to motor vehicle

-------
operation. Some of these defenses have been advanced in radar speedometer
cases but have met with little success.
Reliability of Equipment, and Qualifications of Monitoring Officials
The defense may attack the direct testimony of the expert witness and mon-
itoring officer, or the defense may bring in their own expert to testify that
the sound measuring device might give erroneous readings under certain condi-
tions. Well-documented evidence and expert testimony regarding the proper
testing and operation of the monitoring equipment used to help apprehend the
defendant should serve to minimize the impact of this defense, however.
Similarly, a defense question on the qualifications of police officers who
operate the monitoring equipment may be rebutted by careful presentation of the
officers' training and experience.
Lack of Required Notice
Some jurisdictions require the posting of readily visible signs to provide
notice that radar, for example, is in use in the vicinity. Communities may be
advised to do this in regard to motor vehicle noise enforcement. The City of
Bloomington, Minnesota, for example, posts roadway s.igns that read: "Noise
Ordinance Enforced - City of Bloomington - Ord. 10.29.015." In jurisdictions
where such a requirement exists, it will be necessary to present evidence of
compliance with the notice requirement to counter defense claims of lack of
notice.
Unconsti tuti onali ty
Statutes allowing the use of radio microwaves and other electrical devices
to determine motor vehicle speed have been attacked on constitutional grounds
as violative of rights under the Due Process Clause of the Fourteenth Amendment
Courts have held, however, that radar results can be accepted as prima facie
42
-------
evidence of the speed of a motor vehicle without contravening the Fourteenth
Amendment.6
If the evidentiary relationship between a noise level meter reading and
the actual noise emission level of the motor vehicle can be demonstrated and a
reasonable (through rebuttable) presumption raised that a reading in excess of
limits indicates a noise violation, due process problems should be minimal.7
Apprehension of Wrong Vehicle
The "mistake" argument might be raised in cases where traffic was heavy at
the time .of the violation and where more than one vehicle might have been in
the "zone of influence" of the sound meter at the time the defendant's vehicle
was being monitored. However, since it is good measurement practice that en-
forcement officers not cite a vehicle moving in heavy traffic, mistaken identity
should not create such a problem.
6 See, e.g., Dooley v. Commonwealth, 198 Va. 32, 92 S.E. 2d 348 (1956)
("The test for constitutionality of statutes making proof of a certain
fact prima facie or presumptive evidence of another fact is whether
there is a natural and rational evidentiary relation between the fact
proven and the fact presumed.")

FEDERAL TAMPERING PROHIBITIONS
The Environmental Protection Agency has promulgated emission standards
for portable air compressors2 and medium and heavy duty trucks.3 These regula-
tions require that labels be attached to such products; labels that plainly
reflect EPA prohibitions against tampering.4
1 The Uniform Vehicle Code has been used as a guide for motor vehicle laws by
most states and almost all states have adopted this particular section which
requires vehicles to be equipped with adequate mufflers. Some states go even
further; California requires that the muffler be properly maintained and pro-
hibits modification of a vehicle's exhaust system in a manner that increases
noise emission. The muffler requirement is an effective tool for controlling
motor vehicle noise. Most of the citations issued by the California Highway
Patrol and by local police departments are issued under these sections re-
quiring adequate mufflers. Even though a sound level meter is used, the
section establishing maximum permissible noise levels is rarely cited. See,
e.g., UNIFORM VEHICLE CODE §12-402:
§ 12-402--Noise prevention, mufflers
(a) Every vehicle shall be equipped, maintained and operated so
as to prevent excessive or unusual noise. Every motor vehicle
shall at all times be equipped with a muffler or other effective
noise suppressing system in good working order and in constant
operation, and no person shall use a muffler cut-out, bypass or
similar device. (REVISED, 1971.)

4 For example, air compressor labelling regulations require, this statement:
"This Compressor conforms to U.S. E.P.A. regulations for Noise
Emissions Applicable to Portable Air Compressors." The following
acts or causing thereof by any person are prohibited by the Noise
Control Act of 1972:
(A) The removal or rendering inoperative,, other than for the
purpose of maintenance, repair, or replacement, of any noise
control device, or element of design (listed in the owner's
manual) incorporated into the compressor in compliance with
the Noise Control Act.
(8) The use of this compressor after such device or element
of design has been removed or rendered inoperative."

SUMMARY
Model Ordinance Section 6.2.18 is a general tampering prohibition provision,
while section 9.9.1 specifically applies to motor vehicle tampering.
A tampering prosecution generally involves either one or both of two types
of conduct: 1) removing (or making inoperative) a noise control device; and 2)
using the device or vehicle whose noise control system no longer functions.
Separate causes of action apply to each type of conduct.
An element common to both a product and a motor vehicle cause of action
for removing or making inoperative a noise control device is the requirement
that repair, maintenance or replacement was not the purpose of such conduct.
However, when use of a tampered product or motor vehicle is the allegation, a
difference in proof requirements appears under the Model Ordinance. A prose-
cution for use of a tampered-with product requires proof that the defendant
knew that the device had been tampered with. A prosecution for use of a
tampered-with motor vehicle, on the other hand, does not require similar proof
of knowledge.
Proof of tampering should endeavor to show that the product or motor
vehicle was in a condition proscribed by a tampering statute and its regulations.
Pages 50-51 provide question and answer samples for direct examination of a
manufacturer's representative, mechanic, or noise technician to show tampering.
The most difficult element to prove in a product use prosecution is the
defendant's knowledge of the tampering. The prosecutor might link tampering
and subsequent use allegations together in the same complaint since proof that
the defendant tampered with a product will also fulfill the knowledge element
of the "use" prosecution.
The remedies for tampering violations are standard remedies like those
described in the Model Ordinance (Article XI)[Appendix C]. Certain statutory,
46
-------
evidentiary, and substantive defenses are described on pages 54-56 of this
chapter.
TAMPERING CAUSES OF ACTION
There are two types of conduct that may lead to prosecution for tampering:
1) the removal (or rendering inoperative) of noise control devices or labels;
and 2) the use of a product or vehicle that has been tampered with.
To successfully prosecute a case of tampering with a product that is not a
motor vehicle the prosecutor must show that:
* The product allegedly tampered with was required by law to have a noise
control device, element of design or label, and was listed, as under
Section 4.3.6 (Model Ordinance), as a product for which a tampering
action may be brought;
* The defendant removed, rendered inoperative, or caused to be removed a
noise control device, element of design, or label;
* This removal or rendering inoperative was not for the purposes of repair,
replacement or maintenance of the product; and
* The tampered-with product exceeded noise emission limits (applicable
only to actions based on Federal tampering regulations).
A separate action for the use of a tampered product also lies. It has
three elements:
* The product alleged to have been used improperly was required by statute
to have a noise control device, element of design, or noise label, and
was listed as under Section 4.3.6 (Model Ordinance), as a product for
which a tampering action may be brought;
* The defendant made use of a product whose noise control device, element
of design, or noise label had been removed or rendered inoperative; and
47
-------
* The defendant knew that the noise control device, element of design,
or label had been removed or rendered inoperative.
Because a single defendant may be guilty of both tampering and of the
subsequent use of the tampered product, a prosecutor's best course of action
may be to charge the defendant with both violations in the same complaint.
With these charges linked together, proof that the defendant tampered with a
product would also fulfill the knowledge element of the "use" prosecution.
Prosecution of a motor vehicle tampering case follows a similar
pattern. Two elements must be proven:
* The defendant removed, rendered inoperative, or caused to be removed or
rendered inoperative a muffler or sound dissipative device; and
* This removal, rendering inoperative or causing thereof was not for
purposes of repair, maintenance or replacement.
The operator using a motor vehicle that has been tampered with can also be
prosecuted, based on proof that:
* The defendant operated or caused to be operated a motor vehicle; and
* The motor vehicle at issue lacked a muffler or other sound di'ssipative
device in good working order or in constant operation.
Again,, it may be sound trial strategy to join both motor vehicle violations
in the same complaint. Note that the motor vehicle provisions of the Model
Ordinance do not require a showing that the defendant knew that the vehicle had
been tampered with or knew that the muffler was defective.
TYPES OF EVIDENCE TO SATISFY ELEMENTS
Evidence of Statutory Controls
The prosecutor's task of proving a tampering case is made easier in circum-
stances where product standards or state and local regulations specifically
require that a noise control device, element of design, or label be attached to
48
-------
the product. The owner's manual accompanying certain products, for example, may
carry a list of activities that constitute "tampering" with the product. Such
lists are compiled by EPA after submission by the manufacturer of a proposed
tampering list and are updated from time to time.
Having established that product regulations are in effect, the prosecutor
must further show that the defendant's product is of a model year that was regu-
lated.
Proof of Tampering
It is unlikely that a noise control officer will directly observe a defendant
tampering with a product or a motor vehicle. More likely, the officer will
encounter potential noise violations indirectly during the course of daily enforce-
ment duties. However discovered, to demonstrate that someone has removed or
altered a noise control device, the prosecutor must be able to show that the
product was in a condition prohibited by a tampering statute or its regulations.
That should not be difficult in a case, for example, where a noise control officer
has observed that a muffler no longer is attached to an air compressor and could
so testify on direct examination. In other cases where an alteration affected
an element of design or was otherwise less apparent, additional witnesses may
be necessary. A noise technician from the Noise Control Office (or a police
lab technician), for example, could testify regarding the deviation between
manufacturer's specifications and the present state of the tampered product.
Other techniques to describe the tampering activity to the court might
include the use of photographs. Photographs could be taken of properly installed
product noise control equipment and contrasted with photographs of the tampered
product. In most jurisdictions these photographs would need to be authenticated
or verified by a witness who had observed what the photographs purported to
49
-------
show and who could affirm that the photographs fairly depicted what the witness
observed.
Sample Questions and Answers for Manufacturer's Representative, Mechanic or
Noise Technician to Show Tampering
Qualify the witness as an expert on product design and construction.
Stress experience, or exposure to noise control devices, mechanical or environ-
mental engineering background, and other technical education. If the witness
is a product salesman or mechanic, focus on the length of employment and training
with the particular company, responsibilities, and depth of knowledge with
product lines and design:
Q. Are you familiar with the product (or photograph of the product) I am
showing you now?
A. Yes.
Q. Could you identify it for the court?
A. Yes, it is a portable air compressor, sold by the ABC Company
under the model name Pressure Builder, Model Mo. Series 2001.
Q. J\re you familiar with design and construction of this product?
A. Yes.
Q. Does it contain any device or element of design to control noise
emissions?
A. Yes, starting with Models in 1977 all portable air compressors were
required to have noise control devices.
Q. Could you describe them?
A. Yes. There are a number of features incorporated to reduce noise.
I have the product blueprints with me to help explain these features.
[Lay foundation for these and enter into evidence.]
Q. Could you describe the nofse control devices found on the Pressure
Builder air compressor?
A. There are two baffle type mufflers, insulated exhaust pipes, and a specially
designed exhaust manifold as the primary noise control system. The compressor
has rubber rather than chain belts in the drive train and uses a special
transmission with nylon gears.
Q. Were these features manufactured into all Pressure Builder air compressors
of the model, year and series we are discussing?
A. Yes, to comply with Federal performance standards.
50
-------
Q. Were buyers of this product informed about these features?
A. Yes. The air compressor has a label which informs purchasers of the manda-
tory incorporation of noise control devices. In addition, the instruction
manual, given to purchasers at time of sale, describes the noise control
devices, gives maintenance schedules and techniques and includes a list of
prohibited activities with regard to the noise control aspects of each
product.
Q. Did you have cause to examine a Pressure Builder air compressor for the
police/NCO?
A. Yes, at the request of Sgt. Boomer of the Police Evidence Laboratory, I
accompanied him to examine an air compressor on January 1, 1979, at the
Police Impoundment Lot.
Q. What was the serial number, make, model, and year of this compressor?
A. (Referring to notes) It was a 1978 "Pressure Builder" air compressor,
Serial Number G00007.
Q. Was there anything unusual about this particular compressor? What was its
condition?
A. The compressor was in most respects normal, reflecting a little wear and
tear. However, three modifications had been made to the noise control
equipment.
Q. What were they?
A. The two mufflers had been removed and in their place a piece of straight,
non-insulated tailpipe had been welded. Secondly, the rubber belt had been
replaced with what appeared to be a bicycle chain and the pulley replaced
with a toothed sprocket. Additionally, a standard transmission lubricant
was in the gear box.
Q. What if any, effect would these modifications have on the performance of
the air compressor?
A. They would make the product appreciably louder. I operated the air compressor
at the Police Impoundment Lot and the noise it produced was deafening—far
louder than a properly equipped air compressor.
Q. Were any of these alterations specified as improper alterations in the
operations manual you mentioned earlier?
A. Yes, all three.
Q. Are the replacement parts required for this compressor stocked, and on hand
at the ABC dealership?
A. Yes, these are standard parts, interchangeable among several ABC products.
A sizeable inventory of each is maintained at the ABC warehouse.
Q. Thank you very much. No further questions.
The presentation in court of a tampered product and its unmodified counter-
part is useful to show the tampered status of a product, but it will not show
who the actors were in this tampering activity. Direct evidence that links the
51
-------
tampered status of a product with actions of the defendant owners may be diffi-
cult to find. Circumstantial evidence, therefore, will be critical. This
might include testimony: 1) from product distributors stating that at the time
of sale the product contained a noise control device; 2) from the product owner,
that the product had been continuously possessed since purchase; and 3) from
any intervening borrower as to the condition of the borrowed product. The
goal of such evidence is to show that the product has been within the defendant's
control since purchase, allowing the reasonable inference that any changes to
it were caused by (or were made with the consent of) the defendant owner-
Evidence of Use of Tampered Product
Proof of a defendant's violation of the prohibition against use of a tampered
product is relatively straightforward, with one exception. Testimony by the
noise control or police officer should be sufficient to show that the defendant
operated a product that, by other testimony, has been shown to have been tampered
with. The most difficult element to prove will be that the defendant had
knowledge that the product had been tampered with.
Evidence of Motor Vehicle Tampering
Motor vehicle noise violations usually are not as difficult to proved Tam-
pering prohibitions generally are directed against the removal of mufflers or
other sound dissipative devices. The presence of (or absence of) a muffler can
be spotted easily and the testimony of an apprehending officer should be conclus-
ive. Photographic evidence can provide additional support. When the identity
The judicial rationale offered is that "motor vehicles are operated daily
within the view and hearing of citizens even in sparsely populated areas, and
that any ordinary and interested person would have no difficulty in determining
whether or not exclusive and unusual noise or offensive or excessive exhaust
fumes were being emitted from a particular motor vehicle." Department of Public
Safety v. Buck, 256 S.W.2d 642 (1953).

-------
of the tamperer cannot be proven directly, ownership and circumstantial evidence
may be available to create a presumption as to who the tamperer is.
BURDEN AND ORDER OF PROOF
The burden of proof will vary for each of the above violations depending
on whether individual jurisdictions decide to handle the violation as criminal
or civil in nature.
The order of proof will depend on the facts involved in each case.
Generally, the following guidelines are suggested:
* Establish the regulatory context—i .e., the specific activities that
are proscribed by regulation;
* Establish that the defendant's product or motor vehicle is subject to
these provisions;
* Establish defendant's control, use or operation of product or motor
vehicle.
* Establish the physical condition of the defendant's product through
technical testimony by the NCO, noise technician, manufacturer's
representative, or shop mechanic.
* Establish the distinction between physical condition of defendant's
product and unaltered new product by introducing manufacturer's
specifications (and/or manufacturer's representative's testimony),
testimony of MCO, noise or police lab technician.
* Establish, for use violation, defendant's operation of tampered product
or vehicle by apprehending NCO or police testimony.
* Establish, for product use violation, defendant's knowledge of tampered
condition of product (not applicable to motor vehicles) by proving
possession of knowledge in fact.
53
-------
* Establish (for removal allegation for products or motor vehicles)
defendant's responsibility directly or through inference of possession.
* Specify remedies requested and the proof of facts necessary to support
the request.
REMEDIES
The remedies available for violations of tampering provisions are the same
as those for other provisions of the Model Ordinance. They range from penalties,
to abatement orders, to' injunctive relief where the circumstances warrant such
relief. See Model Ordinance, Article XI, Enforcement [Appendix C].
DEFENSES
There are several defenses that the prosecutor should anticipate in a
tampering or use case. These may be categorized in the following three groups:
* Statutory defenses -- preemption, unconstitutionality;
* Procedural and evidentiary defenses -- illegality of search; gap in
chain of custody; failure to state a cause of action;
* Substantive defenses — removal for repairs; compliance with statutory
controls; lack of knowledge; inadequacy of products.
Statutory Defenses
An argument that Environmental Protection Agency has preempted all local
tampering regulation of products and vehicles will be ill-founded where the
described activities which constitute tampering at the local level are identical
to those identified in the Federal regulations or concern products not covered
at the time of sale by Federal regulation.
A second possible defense might be to challenge the constitutionality
of tampering provisions. Section 9.1.1(a) of the Model Ordinance is particularly
susceptible to such an attack because of its arguable vagueness. It prohibits
persons from operating vehicles which do not have mufflers in "good working
54
-------
condition and in constant operation."5 However, if a jurisdiction has promulgate-1
vehicle performance standards and the muffler provisions are tied to them, this
vagueness argument should be much less persuasive.
Evidentiary Defenses
Standard evidentiary attacks, common to other trials, may arise in tampering
cases as well. For example, the defense might move to suppress certain evidence
obtained by a noise control or police officer without a search warrant.
Substantive Defense
Several arguments may be made to counter the proof of elements presented
by the prosecutor. One is built into the Model Ordinance to the extent that it
provides that tampering is not at issue if the noise device was removed for
repair, maintenance, or replacement. However, intent to repair a product or
vehicle operated in the interim between removal and replacement should not be
sufficient to defend against a use violation charge. A defendant may also
5 Such language has been upheld in challenges to state muffler statutes,
but while tied to other language directed to the prevention of
"excessive and unusual noise." For example, an Alabama statute provides:
Every motor vehicle shall at all times be equipped with a
muffler in good working order and in constant operation to
prevent excessive or unusual noise Ala. Code §39(a)(1958).
In upholding a similar law, a Texas court stated the following rationale:
...[t]he term "excessive and unusual noise" as used refers to noise
in excess of the usual noise which would necessarily result from
the operation of a motor when reduced to a minimum by a muffler
in good working order and in constant operation.... We overrule the
contention that the statutes in question are invalid for indef-
initeness.
The court found the phrase "good working order'and constant operation"
a sufficiently specific standard to define excessive noise. Ex parte

attempt to explain how a product came to be tampered with by shifting the blame
to a repair shop. The subsequent purchaser of a used product might also allege
the prior tampered condition of a product. These assertions conceivably could
undermine proof of causation and/or knowledge to defeat a product tampering or
use prosecution. However, such assertions would not be effective as defenses
to motor vehicle provisions, since knowledge and causation are immaterial to
the use of a vehicle with an inadequate noise control system.
Other possible defenses a defendant might raise include a defense of
compliance with statutory controls, and a defense that although tampering
occurred, the end result was a noise level still within the noise standard.
Statutory interpretation will most likely control the success of these defenses.
PROBLEMS IN ENFORCEMENT
The following are unique problems for a prosecutor bringing a
tampering action:
* A lack of Federal, State, or locally promulgated tampering pro-
hibitions upon which localities can base tampering actions;
* Difficulty in proving the link between tampering and the perpe-
trator.

CIVIL COMPLAINT: PUBLIC NUISANCE
STATE OF IDAHO
In the Supreme Court
STATE OF IDAHO
Plaintiff No. 8976
vs.
New Motor Company
Defendant
57
-------
COMPLAINT
The State of Idaho, plaintiff herein, by its Attorney General brings this
civil action against New Motor Co., defendant herein, and for its cause of action
complains and alleges as follows:
1. That this action is brought by the Attorney General, Idaho, in the name of
the people of the State of Idaho.
2. That defendant is owner of the factory [building] located at Ninth Street in
the city of Boise, State of Idaho, more particularly described as Lot No. 6
at the corner of Main and South Streets.
3. That defendant for a considerable period of time has kept and occupied, and
now keeps and occupies, said factory.
4. That defendant has been operating said factory since July 4, 1963, in such a
manner as to cause excessive noise to emanate from the plant.
5. That said-'noise has impaired the health of the plaintiffs making them nervous
and irritable, and has unreasonably interfered with their sleep.
6. This loud and offensive noise continues during the day and into the late
hours of the night.
7. Such noise is a public nuisance and interferes with the health, safety,
welfare, and peace of the public.
Wherefore plaintiff demands that the defendant, its officers, ser-
vants and agents and all persons under its authority and control be
temporarily enjoined from maintaining and continuing to maintain a
public nuisance, and that on final hearing the temporary injunction be
made permanent.

DISCOVERY
Civil Discovery
The principal tools of civil discovery are: 1) requests for admissions of
fact and genuineness of documents; 2) interrogatories directed at a party; 3)
production of documents and tangible things, including inspection of premises;
and 4) depositions of witnesses, especially of the opposing party's agents or
employees.

*First Requests for Admissions of Fact and Genuineness of Documents
•^Interrogatories to Defendants
*Motion to Produce
^Depositions
*Second Request for Admissions of Fact and Genuineness of Documents
*The Pre-Trial Conference
Penalties for Refusal to Submit to Discovery
The precise rule controlling penalties for refusal to submit to discovery
will differ from court to court but will generally follow the Federal pattern.
Penalties range from a default judgment to imposition of costs. To invoke a
penalty, the usual procedure is to file a Motion To Compel the discovery sought
and then to obtain on Order compelling the discovery. If that Order is disobeyed,
another Motion for Contempt is needed to impose penalties.

Discovery of EPO/NCO
Discovery is available to all parties in a civil action and can be a two-
edged sword. The EPO/NCO should be prepared to submit to discovery. However,
certain items such as reports from independent expert consultants not to be
used at trial, where the expert was retained by the prosecutor (not the EPO/NCO),
may be protected from "discovery as part of an attorney's work product.
Defenses to Discovery
Except as to matters which come within the ever-narrowing ambit of privileged
information, most facts are discoverable if they are relevant. Even irrelevant
facts are discoverable if they lead to discovery of relevant facts. Some
defendants may resist discovery for fear that things discovered in a civil
proceeding could be incriminating and used against them in a subsequent criminal
prosecution. Such fears, however, are easily allayed by the entry of a Protective
Order, limiting the use of such information to the civil action.

Criminal Discovery - Discussion
Although criminal discovery is now more limited than civil discovery,
there is a definite trend toward expanding its scope.5 Depending on local
rules, discovery procedures for the prosecution in a criminal case may be both
limited and reciprocal, i.e., if the defense requests discovery of certain
items, then the prosecution may move for similar items that are in the control
of the defendant.6 Some jurisdictions may grant discovery to the prosecution
independent of any prior request for discovery by the defendant.? Other juris-
dictions allow only the defendant to discover.
A trend appears to be toward encouraging discovery by the parties them-
selves, without the necessity of a court order. However, since this trend is

not necessarily uniform, a form for a motion to compel discovery and inspection
is included in this chapter.
Motion For Discovery and Inspection
Pursuant to the authority of Article , Texas Code of Criminal Proced-
ure, the District Attorney moves the Court to order the defendant to permit the
District Attorney to inspect and copy or photograph the following documents
and tangible objects which are in the possession of the defendant:
1. The certificate of title and registration of defendant's motor vehicle;
2. The muffler that was removed from defendant's motor vehicle;
3. The names of any witnesses who heard the noise caused by the
tampered muffler;
NOTE: [Some jurisdictions may require that the party moving for dis-
covery show that the documents and tangible objects that are
sought to be discovered are material and relevant to the cause
of action. Reasons for discovery must be included in the motion
in order to limit the scope of discovery and prevent "fishing
expeditions."]
As the basis for this Motion, the District Attorney states that the objects
requested are material for the following reasons:
1. The certificate of title and registration is necessary to determine
ownership of the motor vehicle.
2. The muffler is needed so that the prosecution can inspect it and de-
termine whether it has been tampered with.
3. The names of witnesses are needed so that it can be determined whether
the operation of the motor 'vehicle exceeded the sound level.
The District Attorney would further show that the items sought are in the
possession of the defendant and cannot be examined prior to trial except by
court order. The materiality of the items requested will be further shown at
the hearing on this motion. This motion is made in good faith and not for the
purpose of del ay.8

CHAPTER 7: TRIAL TECHNIQUES
SUMMARY
At the pretrial stage, the prosecutor is advised to tap the skills of a
variety of expert consultants to develop a clear understanding of the techni-
calities that certain types of noise prosecutions present. Considerable atten-
tion is paid to the details of selecting experts and on how to prepare them for
trail. The text also points out the information available on noise, its causes
and effects, and how existing research can be brought to bear on a noise prose-
cution.
At trial, an initial task for the prosecutor is to qualify the expert(s)
chosen; page 78 provides a checklist of characteristics and qualifications for
experts. Once qualified, these experts (e.g., acoustical engineers, medical
doctors, noise control officers) can contribute to the development of the testi-
monial evidence needed to support the requisite level of proof required on each
of the various elements of the cause of action pursued in the noise prosecution.
Chapter 7 contains a series of question and answer scenarios designed to
establish the parameters of proof needed to: 1) demonstrate the characteristics
of sound and hearing (p. 79); 20 show the adverse effects of noise (p. 81);
3) illustrate noise control techniques (p. 84); and 4) demonstrate the reliability
of testing procedures (p. 85). This chapter also provides concrete guidance on
still another phase of trial, that of instructing the jury. It offers sample
jury instructions appropriate for the following causes of action: 1) public
nuisance (p. 89); 2) property line standards (p. 90); 3) motor vehicles (p.
92); and 4) tampering (p. 93).
72
-------
Preparing the Noise Violation Case
An interview with the noise control officer/police officer who investigated
the alleged violation should help the prosecutor develop a clear understanding
of the available scientific evidence—evidence likely to play a key role in
successfully prosecuting a noise violator. In such an interview the prosecutor
should:
* Review the facts of the case;
* Ask the officer to draw a diagram indicating the location of
the noise source, the neighboring streets, and other site
features;
* Ask the officer to explain the mechanics and operation of the
noise measurement device used. (This line of inquiry will
solidify the prosecutor's understanding of the available scien-
tific evidence and also 'allow the prosecutor to assess the
potential- of the officer as a trial witness);
* Study and understand the noise measurement readings;
* Determine what written reports or other documentation the officer
has prepared;
* Determine whether the officer has ever testified in court;
It is often helpful during trial preparation to designate as chief consult-
ant one expert witness who has had trial experience and who is familiar with
the broad spectrum of issues in the case. The primary functions of the expert
consultant at this stage will be to help the attorney understand and coordinate
all the data gathered; and to determine what other data will be. needed by way
of tests, samples, and research to fill in the gaps between the facts on hand
and those to be required at trial.
Presenting the Noise Violation Case
Because a noise case involves a substantial amount of technical and scien-
tific evidence, the risk of jury confusion must be anticipated. Demonstrative
and testimonial evidence will assume a critical role.
73
-------
Typical demonstrative evidence for a noise prosecution might include:
* A map of the area involved;
* Tape recordings of the noise;
* Records of recordings from the sound level meters;
* A diagram of the human ear in cases where hearing loss is an
issue; and
* The muffler or noise control device tampered with.
Lay testimony generally will also be important in the typical noise pros-
ecution. Lay witnesses are permitted to describe what they have heard and
whether the noise seemed to be excessive. They may describe the effect on their
hearing and the annoyance, inconvenience, and discomfort caused by the noise.
Noise control officers and police officers may be considered expert wit-
nesses, depending on local law. Appropriate expert witnesses usually include
acoustical, structural or mechanical engineers, instrument experts, and medical
doctors (audiologists and psychiatrists), and psychologists. The medical witness
typically completes the presentation of the case since much of the technical evi-
dence together with lay testimony will form the foundation for the hypothetical
questions posed to the medical witness.•"•
Use of Expert Witnesses
'Experts may be used effectively at both the pretrial and trial stage. Ini-
tially, the expert may help to educate the prosecuting attorney on the technical
issues. The expert may also assist in securing and developing demonstrative
evidence for use at trial. In noise prosecutions, as in others, expert testimony
may be based either on actual observation or hypothetical constructs. An expert
might also be used effectively to demonstrate the operation of the sound meter

(1977).

-------
or other sound measuring equipment to the judge and/or jury. Another important
use of experts is in dissecting evidence presented by the defense.2
Selection of the Expert
In noise prosecutions, as in other cases involving a great deal of scien-
tific and technical evidence, the testimony of the expert witness can be a
crucial, perhaps deciding, factor in the outcome of the case.3 The selection
of an expert should involve an assessment of the expert's professional experi-
ence in a particular noise-related discipline, previous publications, previous
courtroom experience, and whether a court is likely to regard the expert as
impartial.4 The ability to communicate complex ideas using simple, easily
understood language is essential. Although it may be necessary to use more
than one expert to present the prosecutor's case, generally it is advisable to
use a single expert as the principal pre-trial consultant and witness.5
Preparing the Expert for Trial
Just as the expert witness prepares the attorney for trial by explaining
the scientific problems, the attorney must prepare the expert for trial. Even
though the expert may have previously testified in a noise prosecution, he or
she should be counseled as to the exact nature of the specific case, the facts

which must be brought out to prove the prosecution's case, and the types of
questions to anticipate on cross-examination.
Sources of Information
Information on noise, its causes and effects, is available to interested
persons through Federal, state, local and private sources. Appendix E identi-
fies Federal agency sources. Potential sources of state and local information
are identified in the following paragraphs. These sources may contain informa-
tion directly related to the particular matter under investigation or may simply
provide background material on analogous fact situations.
Communities that have adopted the Model Community Noise Control Ordinance
may assign regulatory responsibility to a number of local entities. For example,
the Model Ordinance suggests that a hearing board or administrative court be
established to hear ordinance violation cases, with local courts being utilized
only for administrative appeals. These administrative hearings are potential
sources of information as are worker compensation, occupational safety, or zon-
ing hearings.
The Model Ordinance also recommends various application, review, and plan-
ning procedures, all of which may generate documentary evidence, for example:
* Records and measurements reported by the owner or operator of a
commercial or industrial activity;
* Sound level maps and long term noise control plans;
* Noise impact analysis of capital improvement programs;
* Application for a special variance and application for extension
of time;
* Application for a variance in time to comply; and application
for extension of time;
* Applications to begin construction;
* Reports of an independent testing agency certifying that sound
attenuation measures have been incorporated into the design and
construction of a structure;
76
-------
* Full land site reports;
* Sound analysis reports included within zoning ordinance or com-
prehensive plan approval; and
* Written disclosure of excessive noise levels upon the sale or
rental of a structure or property to be used for human habita-
tation.
In addition, the Environmental Protection Officer may be charged with various
review, recommendation and inspection responsibilities, all of which should
produce some form of written documentation.
By Federal law, a comprehensive environmental impact statement (EIS) is
required for all major Federal actions significantly affecting the environment.
Many states and some communities have adopted similar requirements. The compre-
hensive information contained in an EIS may help a judge or jury appreciate the
overall significance of noise problems and may help them relate noise to other,
more widely understood types of environmental pollution. The EIS document may
contain charts or diagrams useful in the courtroom, a's well as information on
noise experts familiar with the local area.

Sample Questions and Answers Showing Characteristics of Sound and Hearing
An acoustical engineer, audiologist, or otolaryngologist may be an appro-
priate expert witness to testify about the characteristics of sound and hearing.
Q. We have here a case in which excessive sound emissions are alleged. What
exactly is "sound"?
A. Sound is a vibration in matter, in a substance of some kind. We usually
speak of sound as traveling in :'waves," similar to the waves on the ocean.
(The water itself does not travel, but the wave motion does.) Similarly,
sound waves travel as successive vibrations through a substance. There
must always be a substance of some kind.
Q. What kinds of substances transmit sound?
A- Anything in which the molecules can "bump" against each other. Sound will
travel in air, of course, but also in water, in iron (as in a railroad
track) and in most matter. In fact, it can travel better in a solid, like
the railroad track, than it can in air-
Q. Is there a science which is concerned with sound waves?
A. Yes, the area of science which is concerned with the production, propaga-
tion, reception and control of sound waves is called "acoustics."
Q. What types of sounds are there?
A. The word "sound" is usually thought to mean only things that people hear,
but actually there is a wide range of sounds, most of which we cannot
hear. There are sounds of low frequency that are inaudible, "but they may
be felt. At the other extreme, there are notes so high that humans cannot
hear them, although dogs and other animals may hear them quite well.
Q. How is sound described?
A. Sound has speed, frequency, intensity, and duration. The speed of sound
in air depends on the density of the air. As a convenient base, we usually
say that sound travels 1,130 feet per second in dry air at 70 degrees F.
and a barometric pressure of 29.92 inches of mercury. That is, about 770
m.p.h., although that speed is rarely achieved since we rarely find perfectly
dry air in nature.
Q. How do you define frequency and intensity of sound?
A. The frequency of sound is sometimes called its "pitch," and is what we
often refer to as "high" notes and "low" notes. Frequency is actually
the rate at which the sound waves arrive at a place, such as the ear.
Again, picture waves in the ocean, but now they are washing against a
shore. If the waves are far apart and only one hits the shore each minute,
then we can say the wave rate is one per minute. If the waves start coming
ashore more frequently, say three per minute, then we can say that the
"frequency" of the ocean wave pattern is three per minute. Note that I
didn't say how big the waves were. They could be huge tidal waves, or tiny
ripples. The size or power.or the wave is its "intensity."
78
-------
Q. What are the frequencies of sound waves?
A. Sound waves are measured according to the number of waves that strike the
ear (or recording instrument) in a second. Between the peak of two waves
there is a valley, and these waves and valleys repeat in cycles, so we can
refer to frequency measurement as cycles per second, or c.p.s. The scien-
tific term for this is "Hertz" (Hz).
Q. What range of frequencies can be heard by the normal human ear?
A. A good human ear can hear sounds with frequencies from 20 Hz to 20,000 Hz,
but the extreme ends are hard to hear. The most sensitive range is from
about 500 Hz to 5,000 Hz.
Q. What is a decibel?
It is not a fixed absolute value, like an inch or a frequency. Rather, it
is simply a ratio, telling by what proportion one value is greater or less
than, another. To give a decibel system a base, it is presumed that an
acoustic pressure of 0.0002 dyne per square meter is zero decibels. This
is about the intensity of the faintest sound at 1000HZ that a normal young
person can hear under the best listening conditions. This would have to
be an extremely faint high note, almost as high as the highest note on a
piano. What is further complicated about decibels is that the decibel
scale is not a straight-1-ine measurement, but is logarithmic. Thus, a
10-fold increase in acoustic power above the faintest sound that a young
person, could hear is measured as 20dB. A 100 times increase in pressure
is 40dB, and so forth.
Q. What range of decibels can humans hear?
A. That depends on the frequency. We hear, for example, sounds that have a
pitch in the top one-third of the piano keyboard better than other tones.
We hear treble better than bass. You might hear a soprano voice at lOdB
but a bass would have to hit you with 35dB to be audible. For this reason
some decibel scales are "weighted," that is, the measurement system is al-
tered somewhat to fit a particular purpose. The difficulty in measuring
decibels is that an instrument must be made to measure what we hear. An
instrument would usually sense all sounds equally, no matter what the
pitch, while the human ear does not. To us, a treble note at 40 dB might
sound "louder" than a low tone at 40 dB, but to an instrument recording
only pure acoustic pressure, it would show the same.
Q. What can be done about that?
A. What we do is alter the decibel scale to fit the job. For example, we
usually use a measurement system called the "A-weighted" decibel scale,
abbreviated dB(A), so as to show sound intensity levels as sensed by the
human ear. Another factor considered in the "weighting" of a decibel
scale is the complexity of sound and the fact that it is almost never
pure.
Q. So a sound-measuring device can be made to compensate for this problem?
A. Yes, this and others. When more than one frequency is present, the meter
reads the over-all sound level. It gives a result according to its cali-
bration, and if using the dB(A) scale, it adjusts its A-weighting pressure-
frequency receptions to give a decibel readout approximating what the
human ear would hear in total loudness.
79
-------
Q. What is noise?
A. Noise is highly subjective. But in general when we say noise we mean a
composite sound, consisting of many combined frequencies and qualities,
and that the composite sound is undesirable.
Q. Is loud noise more harmful than loud music?
A. If a sound is loud enough to be harmful, it makes no difference whether
it is a noisy jumble of frequencies without form or pattern, or a loud
pure tone. However, there may be a secondary psychological difference.
Music at 100 dB(A) may be exciting and stimulating, but so-called "noise"
at that level may be extremely annoying.
Q. At what point does a sound become harmful?
A. That depends on many things, including the kind of person involved. No
tests are available that enable us to say with scientific certainty what
sound levels will always be harmful or what levels are always safe for
everyone. We do know what sound levels will cause discomfort and pain.
Q. How is sound propagated?
A. Sound waves usually spread out evenly in all directions from the source.
If you toss a pebble in a quiet pool, the ripples spread out evenly in all
directions, in concentric circles from the source. Sound waves do the
same, although in concentric spheres, or cone-shaped broadcasts.
Q. Do sounds change in frequency and intensity as they travel?
A. Frequencies which come from a stationary source usually remain the same,
barring acoustical reflections, etc., and assuming the hearer is not moving
either. However, the power or intensity of the sound is dissipated as it
travels. There is a mathematical formula by which one can calculate the
spreading of the intensity of a sound wave. The intensity of a sound wave
diminishes in proportion to the inverse square of the distance from the
source. In layman's terms, it is less loud the farther away you are.
Q. Does distance from the sound make it more tolerable?
A. No, not always. It is very rare to find a sound emitted in the middle of
a spherical space. A noise made just above the ground really only has one
half of a sphere of air to travel in. And the science of acoustics has
demonstrated that many changes can occur to a sound as it dissipates.
Sample Question and Answers Showing Adverse Health Effects of Noise
The following questions would be appropriate to elicit information on the
adverse effects of noise. A qualified otolaryngologist could bring out these
facts, although other experts with similar background might be equally appropri-
ate.
Q. Doctor, can exposure to loud sounds be harmful to humans?
A. Yes, if the sounds are loud enough, and/or the exposure long enough.
80
-------
Q. How loud must sounds be to be harmful?
A. It is a function of intensity and frequency and time of exposure. A very
loud forceful sound, like the firing of a cannon while standing next to it
can destroy a man's hearing in a single burst. But hearing can become
impaired also by sounds of less intensity, volume, and loudness, if the
person is subjected to them long enough.
Q. Does a sound have to be loud enough to be painful in order to cause damage?
A. No. Sound usually becomes painful at about 140 dB. Levels of 150 dB or
more may be found near the exhaust of jet engines and rockets, and expo-
sures to such sounds will cause rapid injury. That is why most line crew-
men at jet airports wear ear protection. For less severe exposures the
damage takes longer. Nonetheless, such exposures, day after day and week
after week, year after year perhaps, can cause temporary hearing loss, and
if further continued, that hearing loss can become permanent.
Q. How do you determine whether a person is likely to sustain a hearing handi-
cap from sound exposure?
A. We know the percentage risk of developing a hearing handicap based on age
and the noise-exposure index in decibels. Research has been done on this
and data are available.
Q. What is a decibel exposure index?
A. Simply put, it is a measure of the total amount of sound to which the per-
son has been subjected. We know that one measure of noise-induced hearing
loss is the total amount of sound received. The index is a function or
calculation of the exposure time to the sounds and the energy of dB of the
sound. We call it the 3 dB(A) rule, because every increase of 3 dB(A) in-
dicates a doubling of the energy of the sound. What this rule says is
that listening to a sound level of 90 dB(A) for 4 hours, for example, has
the same effect as listening to a level of 93 dB(A) for 2 hours. The
noise-exposure index would be the same for both. So, a lifetime noise
exposure index would reflect the total amount of energy the ear has been
subjected to, expressed as the equivalent continuous sound level in dB(A).
Q. Then you are using an average of all the various sound levels and hearing
times?
A. Not an average. It is hard to explain, but let me use an example. Suppose
a person is exposed 20 hours per week to a sound level of 100 dB(A). A
calculation by the 3 dB(A) rule gives that a total sound level of 500. The
equivalent continuous sound level would be 97 dB(A). The effect of the
ear would be the same as if he was exposed to 97 dB(A) for the whole time.
Q. What is the effect?
A. Exposure to loud noises, even though not for very many hours a week, if
continued long enough, can have effects as damaging to hearing as extremely
loud or painfully loud sounds have in a shorter time.
Q. What kind of hearing loss can occur because of noise exposure?
A. The first losses are temporary. Usually what happens first is loss of the
ability to hear the high tones, the trebles, say between 4,000 and 6,000
Hz. If the loss is caused by sounds in a particular frequency range, as
in a rock musician for example, the first loss is usually in the ability
81
-------
to hear sounds about 1/2 octave above the exposure notes. With repeated
exposures, these temporary losses become more permanent, the disability
spreads to lower tones, until eventually it gets down to 3S000 Hz and
lower, which is within the frequency range of human speech. Then we begin
to have a real critical impairment, a difficulty in understanding speech,
a partial deafness.
Q. Can noise-induced exposures produce a permanent hearing loss that can
affect communication by speech?
A. Yes. Such loss may be temporary, permanent, or both. It is caused by
destruction of certain inner ear structures which are impossible to replace
or repair, the so-called organs of Corti. The amount of loss varies from
person to person.
Q. Are the sound energies and frequencies recorded at point A here harmful?
A. Do you mean physically harmful, likely to cause hearing loss?
Q. Yes, at least let me begin with that question.
A. I can only say that the sound level at A creates a risk of inner ear damage
and resultant hearing loss, if imposed upon certain kinds of people long
enough.
Q. Of the type of people who are exposed to this noise, can you calculate
what the hearing handicap risk is at A?
A. Yes. Using the recorded noise levels and knowing that the largest group
of adults exposed to those sounds about hours per week, and that it
has been there for over 10 years, we can calculate the equivalent continu-
ous sound level in dB(A) at 100. Of those who have been hearing that
sound that often for 10 years, we can determine that slightly over 20% now
have the risk of suffering noise-induced hearing loss.
Q. If we have proof here that there are 326 people who have such exposure,
how many are likely to suffer harm?
A. I would say the risk is that about 65 people will suffer some degree of
hearing loss because of the defendant's noise broadcast. I am talking
about actual physical organic inner ear hearing loss. Many more would
suffer adverse effects which are not objective medically but nonetheless
real . They may suffer from the psychological effects.
Q. What are those?
A. These are things like annoyance and discomfort, nervous tension, sleep-
lessness, and the like. Noises can cause these symptoms even though not
intense enough to cause actual physical damage.
Q. Are these kinds of effects nonetheless real?
A. They may be more real to the victim of the sound than are the subtle,
slowly "building effects of organic hearing loss. When a person cannot
sleep properly because of noise, that person often becomes irritable and
cranky. Sometimes resistance to disease is lowered. Continuing high
noise levels can be quite bothersome and actually interfere with the qual-
ity of life. It is not a coincidence that we associate relaxation, happi-
ness, and serenity with "peace and quiet". Noise and confusion, especially
noise in large, long doses, definitely leads to irritability, temper flare-
ups, nervousness and antisocial behavior.
82
-------
Q. Are these kinds of things permanent?
A. There are many possibilities; I'll describe two. Suppose, due to excessive
sound levels, a person cannot get the proper amount of sleep for many
days. Suppose also that this person is made nervous and irritable because
of the noise, and complains about it often. Now suppose that as a result,
resistance to disease sets in and the person gets some infection, such as
a virulent flu, pneumonia or the like. Such a disease might leave perman-
ent residual difficulties. Or, a person with high blood pressure might
find it aggravated by exposure to continuous or repeating loud noises.
Q. What are the percentage risks of such subjective effects to a population
subjected to high noise levels?
A. We cannot say. We know that more people complain about this kind of thing
than actually have objective hearing loss. Again, it depends on the indi-
vidual -- age, time of exposure, living habits, and condition of health.
Also, if the noise is a constant one, some people become acclimated to it.
Q. So if a person can become used to the noise, and adjust to it, it is no
longer a problem?
A. It may be worse, in the long run. A- person who is annoyed by the sounds
may take self-protective measures if available, and try to reduce the
sounds being heard, thus protecting and preserving the inner ear. But the
acclimated individual may just subconsciously ignore the noise in his
head, not knowing that the ear is hearing the noise anyway, and slowly but
surely causing a hearing impairment.
Sample Questions and Answers to Show Noise Control Techniques
An acoustical engineer would be qualified to discuss the techniques, avail-
able for controlling noise.
Q. What can be done to prevent or reduce excessive sound levels?
A. Well, there are a number of approaches. First is personal protection,
which means some way of covering the ears to keep the sound out. The
second way is by environmental control.
Q. What do you mean, environmental control?
A. Keeping the sound levels down in the affected environment. What we are
talking about is reducing the amount of noise produced by the source,
reducing the amount of noise transmitted through air or buildings, and
revising operational procedures.
Q. How can revising operation produce reduced noise effects?
A. Simple, according to the 3-dB rule, for every halving of the exposure time,
doubling the energy (i.e., an increase of 3 dB) is permissible without in-
creasing the risk. Suppose you have a machine which cannot be operated
without producing 98 dB, no matter what one does, but it can be made more
efficient and can be run only 8 hours per day instead of 16 through effi-
cient management and time utilization. Cutting the time in half has the
same effect on those exposed as if the sound produced was reduced to 95 dB.
83
-------
Q. How can one achieve the other two types of environmental control?
A. The control techniques are similar in each type. On one hand we try to
reduce the sound coming from the source, and on the other we try to reduce
the sound traveling to the injury risk area.
Q. What are some ways to control sound in the environment?
A. We use the same laws of acoustics that can cause excessive noise, only we
turn them to our advantage. What we do is get the sound to dissipate its
energy harmlessly.
Q. Tell us some ways this can be done.
A. Well, distance is one way. Keep noisy things far away, because sound de-
creases its energy with distance. Damping devices and barriers are another
approach. Things like thick fabrics, fiberglass, cork, acoustic tiles,
all serve to "soak up" sound. What they actually do is break up the sound
waves and get them reflecting and refracting in tiny microscopic spaces
between the fibres, until they dissipate their energy.
Q. How would you recommend the reduction of sound levels to tolerable
levels?
A. Well, there is nothing we can do about pure distance, without moving either
the source or the affected place, but we can make the sound move farther
in getting there by installing baffles that the soundwave must pass around.
The offending sources can be surrounded with absorbing panels and baffles.
The walls in defendant's premises can be coated with a damping substance.
The large walls can have separations in them, or portions made of a differ-
ent material, to impede sound waves from making a "sounding board" amplifi-
cation in them. Wherever there are vents or stacks which cause a rushing,
roaring and similar sound, these should be equipped with muffling devices,
like a car muffler. These devices serve to break up the soundwaves and
lengthen their travel distance to the outside.
Q. Are these remedies feasible with today's technology?
A. Yes. All are within the current state-of-the-art knowledge and capabili-
ties. They are on the market, or easily fabricated.
Q. Is there any reason why defendant could not have installed noise control
measures such as these 7 years ago?
A. The technology was available at that time.
Q. Thank you. Defense counsel may cross-examine.
Questions and Answers to Establish Reliability of Testing Procedures
Either the acoustical engineer, the noise control officer or police officer
(assuming the latter two have appropriate background and training) may testify
as to appropriate and/or actual testing procedures. The following facts and cir-
cumstances, among others, tend to establish that a scientific device, process,
84
-------
or technique is sufficiently reliable that evidence resulting from its use may
be admitted in court:
* Manner in which the device works;
* Range of uses of the device;
* Theoretical possibility of errors in design, manufacture, maintenance,
or operation of the device;
* Nature and relevance of errors that may occur;
* Routine maintenance, quality control procedures, and other precautions
against errors;
* Results of tests of reliability and accuracy of device;
* Validity of statistical evidence of reliability;
* Opinion of expert as to reliability.7
Testimony eliciting this type of information constitutes the first part of
the foundation necessary before evidence produced by sound measuring devices
may be admitted in court. In courts where judicial notice of sound measuring
device reliability is taken, this step may not be necessary, but it must be dem-
onstrated in all cases that the particular equipment used by the officers was
of an appropriate type and in proper working condition, and that the person
using the device was qualified to do so. Testimony to bring out these factors
in an officer's testimony is discussed on page 30, supra.
Q. Have you seen the noise sources complained of here?
A. Yes.
Q. Do you know what the characteristics of sounds from that place are?
A. In a general way, yes. I cannot trace for you the path and changes in
each and every sound wave, but that is not necessary for an evaluation of
the site as a sound source.
Q. What is your evaluation of the place as a sound source?
A. It is definitely a source of sound. As has been admitted, the facilities
there are of a large number and emit sounds of various kinds. These sounds
come from different points, but to a distant listener, they seem blended
7 2 Am Jur 2d, Proof of Facts, §3, at 545 (1974)
85
-------
together, and in a large part they are. The structure of the place and
its surroundings are not acoustically designed, and do little to reduce
the dB levels.
Q. How do you find out to what extent this is true?
A. The best way is not by trying to trace and calculate each sound, but simply
to measure it at different places.
Q. Have you done this?
A. Yes.
Q. When?
A. On 19 and we conducted
tests as selected places in the vicinity.
Q. Where were these done?
A. We put instruments at the locations indicated on the map there.
Q. What kind of instruments did you use?
A. We used which are the commonly accepted standard
instruments used to measure sounds in this kind of sampling network.
Q. Do these have to be calibrated prior to being used?
A. Yes, they are checked out prior to use by taking readings on them from a
known sound source, a series of pitches and intensity that we create elec-
tronically, to make sure that the instrument is reading correctly.
Q. Who did this?
A. I did it, together with a technician who worked under my supervision.
Q. Why did you select those particular locations for the samplers?
A. We selected location A because it is in the center of the area where we
were informed the most complaints came from. We put other instruments at
B, and at C, in line with A and the suspected source to check the intensity
levels and dispersion of the sound. We put one at D, in another direction,
85 compass degrees from the suspected source, as a control.
Q. Were you able to find any sound levels?
A. Yes, there were sound levels of some type all the time. We were interested
in the type of sound and its source.
Q. Were you able to find the source of any sounds?
A. Yes, there were some general background noises, such as birds, leaves
rustling in the winds, local auto traffic and such, and there were sounds
which came from defendant's facility.
Q. How were you able to find the source of the latter sounds?
A. In three ways. First, we ran the instruments at night, on weekends, and
other times when the defendant was not operating. We found increased
sound levels on all instruments when it was operating as compared to when
it was not. Second, two of the instruments, at A and D are capable of
sensing the direction from which the sounds come. When the levels con-
sisted only of background noise, i.e., when defendant was not operating,
the sounds did not come from any one direction more than others, particu-
86
-------
larly. But when defendant's operation started up, the increase in sound
levels showed as coming from a definite direction. At A they came from
the direction shown by the green arrow here on the map. Point D is 85%,
almost at right angles on the compass, from A. The instrument at D showed
the source of the excess sound to be from the direction shown by the blue
arrow. By extending these two vector arrows until they cross, as here,
[demonstrating] we see that they pinpoint the source of the sound, here,
right on the defendant's premises.
Q. What is the third way to find this?
A. By experience and in the scientific literature, and from what has been
discovered about defendant's operations, we know certain kinds of sounds
to be typical of its kind of activities. We found that the sounds we
recorded fit these characteristics.
Q. Did you record the sounds so they can be played back?
A. I made graphic recordings, showing the sounds as patterns on a graph paper
roll.
Q. You have referred to the sound from defendant's premises as "excessive"
noise. What do you mean by that?
A. I mean that it is not only more sound than the usual background noise, but
it is sound which may have had adverse impacts on human health and welfare.
Q. In what areas?
A. At point A, over % of the time, we recorded sound at levels for which
adverse health impacts have been noted.
Q. What about other places? What levels did you record?
A. Well you see here on this table the various sound levels taken from each
location on the dates stated. On this other exhibit we have made a graph
showing the average recorded levels in dB(A) at each place. Note how it
is highest at A, and shows the average sound levels at A to be dB(A)
when defendant was operating.
Q. Why are the levels higher at A than at C when C is actually closer to the
plant?
A. There are several explanations for this. First, much of the sound from
the plant comes from its upper level and roof portions. The bulk of the
building itself tends to shield recordings at C from the direct energy of
these sounds. They get to C by diffraction and reflection. Further, we
see on this photograph that there are trees and shrubs close to C which
tend to absorb sound waves. Mow take A in contrast. It is stands in a
direct line from the upper sound sources. The building further out has a
wall, here, which is hard and smooth and makes a very good reflector,
bouncing sound back towards the source. Also, we noted that instrument C
is in the "green belt." During the nighttime operation especially, the
temperature of the air, and its density, is often quite a bit different
there than right at the source. I have the opinion that this causes a
refraction of sound waves from sources near the surface, before they get
here to C. Some of these are reflected downward to be absorbed by the
lawn and shrubs, but others are refracted upward, where they join with
those from the upper sources. The net result of all these is that the
vicinity of A is a "hot spot" of noise, so to speak, where sounds coming
87
-------
from defendant's sources are modified and amplified by the environment to
produce a very unpleasant and annoying, if not dangerous, sound level.
SAMPLE JURY INSTRUCTIONS
Public Nuisance
Plaintiff's Requested Instructions
I. Plaintiff's Theory and Claim
The State (plaintiff) theorizes and claims that the defendant created ex-
cessive noise which emanated from its plant and which caused a public nuisance
within the meaning of the laws of this State. According to the plaintiff's
claim, the public nuisance existed from August 1962 to August 1963. The State
further claims that this pollution created a hazard to the health and safety of
the public.
II. Public Nuisance - Definition
A public nuisance is defined as an activity, or conduct, or a set of cir-
cumstances that causes significant interference with or damage to the health,
safety, peace, convenience, or comfort of the public. A public nuisance cons-
titutes interference with a right common to the general public.
Under the Taw of this state, when a manufacturing establishment unreason-
ably creates any sound which endangers the health or safety of any person or
property or a sound which injures any person or property, that manufacturer
is creating a public nuisance.
III. Public Nuisance - Elements of Proof
The State has the burden of proving by a preponderance of evidence that
the defendant caused a public nuisance.
The elements of public nuisance which the State must prove by
a preponderance of the evidence are:
1. That interference with a right common to the general public took place;
88
-------
2. That the interference was unreasonable; and
3. That the public right is a substantial right.
If you find that these three factors existed at the time in question and
that the public health, safety, peace, convenience or comfort was endangered,
then you must find that a public nuisance exists.
IV. Nuisance - Evidence of Muisance
Violation of Ordinance
You are instructed that:
No person shall unreasonably make, continue, or cause
to be made or continued, any noise disturbance.
Noise disturbance means: any sound which (a) en-
dangers or injures the safety or health of humans or
animals, or (b) annoys or disturbs a reasonable per-
son of normal sensitivities, or (c) endangers or in-
jures personal or real property.
If you find from the facts that the defendant was engaged in any of these
prohibited activities, then you may find that the defendant has committed a pub-
lic nuisance.

I. Property Line Standards - Violation of Ordinance
You are instructed that:
No person shall operate or cause to be operated on
private property any source of sound in such a man-
ner as to create a sound level which exceeds the
limits set forth for the receiving land use category
in Table I below when measured at or within the
property boundary of the receiving land use.

the evidence of property line standards.
II. Property Line Standards - Elements of Proof
The State has the burden of proof [by a preponderance of the evidence/beyond
a reasonable, doubt] that the defendant caused a source of noise to exceed the
limits set forth for certain receiving land use categories.
The elements of a property line standards violation which the plaintiff
must prove [by a preponderance of the evidence/beyond a reasonable doubt] are
the following:
1. That a person operated or caused to be operated on private property a
source of noise;
2. That if the noise occurred in a residential zone or in a public space,
agricultural or industrial zone, the noise exceeded the sound level
limits for the day or evening; and
3. That the noise exceeded the standard set for the receiving land use
category when measured at or within the property line.
If you find that these three facts occurred at the time in question, then
you must find that the defendant violated the property line standards provision
of the statute.

You are instructed that:
No person shall operate or cause to be operated a public
or private motor vehicle or motorcycle on a public right-
of-way at any time in such a manner that the sound level
emitted by the motor vehicle or motorcycle exceeds the
level set forth in Table II.
If you find from the facts that the defendant was, during any of the time

The State has the burden of proving [by a preponderance of the evidence/
beyond a reasonable doubt] that the defendant violated the law of this State by
operating a motor vehicle in excess of the sound level set by the statute.
The elements of proof which the State must prove [by a preponderance of
the evidence/beyond a reasonable doubt] are:
1. That the defendant operated or caused to be
operated a motor vehicle or motorcycle on a
public right-of-way; and,
2. That the motor vehicle or motorcycle was
operated in such a manner that the sound
level emitted exceeded, the limits set
forth in the ordinance.
If you find from the facts that these two conditions existed at the time
«
in question, then you must find that the defendent violated the motor vehicle
provi si on.

Tampering Sanctions
Plaintiff's Requested Instructions
I. Tampering Sanctions - Violations of Ordinance
You are instructed that:
The following acts or the causing thereof are pro-
hibited:
(a) The removal rendering inoperative by any
person other than for purposes of maintenance,
repair, or replacement, of any noise control
device or element of design or noise label of
any product identified under Section 4.3.6. The
EPO/NCO may, by regulation, list those acts which
constitute violation of this provision.
92
-------
(b) The (intentional) moving or rendering naccurate
or inoperative of any sound monitoring instrument
or device positioned by or for the EPO/NCO, pro-
vided such device or the immediate area is clearly
labeled, in accordance with EPO/NCO regulations,
to warn of the potential illegality.
(c) The use of a product, identified under Section 4.3.6,
which has had a noise control device or element of
design or noise label removed or rendered inoperative,
with knowledge that such action has occurred.
If you find from the facts that the defendant was, during any of the time
in question, in violation of the terms of that statute, then you may consider
the evidence of tampering.
II. Tampering Sanctions - Elements of Proof
The State has the burden of proof [by a preponderance of the evidence/beyond
a reasonable doubt] that the defendant removed or rendered inoperative a noise
control device.
The elements which the State must prove are the following:
1. The product alleged to have been tampered with, was
required by law to have a noise control device, ele-
ment of design or label;
2. The defendant removed, rendered inoperative, or caused
to be removed a noise control device, element of design
or .label; and
3. This removal or rendering inoperative was not for the
purpose or repair, replacement or maintenance of the
product.
A separate action for the use of a tampered product also lies. The following
elements are needed:
93
-------
1. The product alleged to have been used improperly
was required by statute to have a noise control
device, element of design or noise label; and
2. The defendant made use of a product, whose noise
control device, element of design or noise label
had been removed or rendered inoperative.
If you find that these factors existed at the time in question, then you
must find the defendant in violation of the tampering prohibition.

CHAPTER 8: FEDERAL PREEMPTION
NOISE CONTROL ACT OF 1972. 42 U.S.C. 4901 et seq.:
...[w]hile primary responsibility for control rests
with the state and local governments, federal action
is essential to deal with major noise sources in commerce,
control of which require national uniformity of treatment.
SUMMARY
Often, a state or local prosecutor of noise violations will confront the
issue of the interaction between Federal and local authority for noise control.
The Noise Control Act of 1972 stated the intent of Congress that noise coatrol
be a cooperative effort between the Federal and local governments. That Act
placed primary authority for control of noise with State and local governments
subject, however, to preemptive Federal authority in particular contexts where
a pervasive scheme of Federal noise regulation was in existence.
In general, the test of whether both Federal and local noise regulations
may operate, or whether local regulations must give way, is whether both regu-
lations can be enforced without interfering with the Federal regulations in the
field, and not whether Federal or local regulations are aimed at similar or
different objectives.
Federal preemption of noise control is most pervasive in the area of air-
craft noise, although even here some noise controls may be applied by states
and localities, provided that these controls are not discriminatory and do not
substantially interfere with interstate commerce.
Interstate rail and motor carriers also fall within the potentially preemp-
tive umbrella of Federal noise controls. However, local enforcement authority
may be exercised in those circumstances where local noise standards are identical
to those prescribed by Federal regulation.
95
-------
Federal preemption also touches products regulated by the Environmental
Protection Agency as major noise sources, although this preemption is not as
pervasive as it is in the case of aircraft or interstate rail and motor carrier
noise.
THE PREEMPTION DOCTRINE AND THE CONSTITUTIONAL BASES FOR FEDERAL, STATE AND
LOCAL NOISE REGULATION '
The preemption doctrine has its roots in the Supremacy Clause of the
Constitution:1
This Constitution and the Laws of the United States which shall
be made in Pursuance thereof;... shall be the supreme Law of the
Land; and the Judges in every state shall be bound thereby, any
Thing in the Constitution or Laws of any State to the Contrary
notwithstanding.
In short, where state regulation interferes with or is contrary to the laws
of Congress, it must yield.2 Yet, the field of noise regulation is one in which
both the Federal and state governments have solid constitutional bases for in-
volvement. The police powers reserved by the Constitution to the states (and
delegated to local jurisdictions by state enabling legislation) afford strong
support for state and local efforts to protect the public health and welfare
through regulation of noise.
As state police powers infringe upon Federal regulation of commerce, how-
ever, the likelihood of preemption increases. The Supreme Court enunciated the
classic preemption test in Cooley v. Board of Wardens.3 The essential determin-
ant is whether commercial regulation by a state "admits of only one uniform sys-
tem or plan of regulations." If this is the case, regulatory power is exclusively

3 53 U.S. 298, 12 How. 298 (1851).
96
-------
Federal. But, where subjects of commerce require "that diversity [of regula-
tion] which alone can meet local necessities," concurrent efforts at all levels
are appropriate, under the Cooley test.4
The Noise Control Act of 1972, as amended by the Quiet Communities Act of
1978,5 envisions joint enforcement responsibilities for the Federal and state
governments. With some exceptions, Federal noise control efforts center on
identifying noise sources in commerce and on establishing product performance
standards for manufacturers. In contrast, state and local efforts under nuisance
theory (see_ Chapter 2, supra) and local noise ordinances usually have focused
on the control of environmental noise through zoning, operational restrictions,
and other prohibitions (both subjective and objective) against excessive noise
rather than on setting specific requirements for new articles in commerce. Where
a state or Tocal Noise«Control Ordinance employs performance standards for new
products at the time of sale, the standards are not preempted if they are ident-
ica'l with Federal limits, and thus assure uniformity.
AREAS OF FEDERAL PREEMPTION AND RESIDUAL STATE AND LOCAL AUTHORITY
Transportation Noise
Aircraft and Airport Noise Regulation -- The area where Federal preemption of
noise control has generated the most controversy and uncertainty is airport and
aircraft noise. Much of the controversy stems from the fact that while extensive
4 This balancing of national uniformity versus local sensitivity has been
expanded in subsequent cases. For example, in Mines v. Davtdovitz, 312
U.S. 52, 67 (1941), preemption of local regulation was dependent upon a
showing that the law in question was "an obstacle to the accomplishment
and execution of the full purposes and objectives of Congress." Similarly,
in Florida Lime and Avocado Growers, Inc. v. Paul, 373 U.S. 132 (1963),
congressional intent was deemed to be dominant in deciding on the coexis-
tence of Federal and state regulations..

-------
Federal aviation regulations apply to airports and aircraft,6 few airports are
Federally owned and operated. In fact, states, or elements of local governments,
own and operate most of the airports around the country-
In 1962 the Supreme Court held that municipal airport operators could be
held liable for noise-related disturbance and damage under the theory of inverse
condemnation.7 In part to reduce their liability exposure, some localities re-
sponded with curfews, weight limitations, minimum altitude standards, and even
absolute landing prohibitions. Most of these efforts failed under judicial
scrutiny, however, as courts held that the municipal police power must yield to
the pervasive scheme of Federal aviation regulations."
Subsequent court decisions have created a "proprietary" exception to Feder-
al preemption of aircraft noise control, allowing certain limited restrictions
which are non-discriminatory, reasonable, and focus on reduction of land impacts
6 The Federal aviation regulations that generally supplant state airport
noise initiatives are based on the Federal Aviation Act of 1958, 49 U.S.C
§1301 et seq., as amended by the Noise Control Act of 1972, 42 U.S.C
§4901 et seq. Under this- scheme, the Federal Aviation Administration
(FAA) is required to set rules and standards "to provide for the control
and abatement of aircraft noise and sonic boom," and to incorporate
these standards into aircraft certificate requirements.
The FAA has set operational requirements for jet aircraft, prohibiting
airspeeds which would cause sonic booms (Air Traffic and General Operating
Rules, 14 C.F.R. §91.55), and has issued advisory guidelines on takeoff
and approach procedures. The FAA has issued numerous aircraft noise per-
formance standards, the most significant being Federal Aviation Regulations
(FAR) Pt. 36 (14 C.F.R. Pt. 36), commonly referred to as FAR 36. The Environ-
mental Protection Agency through a six-step procedure, may consult, recom-
mend, submit standards, and request that they be reviewed (49 U.S.C.
§1431(b)(2), as amended (Supp. 1978).

-------
rather than on aircraft flight.9 The essential argument is that as a concomit-
ant of being liable for aircraft noise, the airport proprietor should have some
authority to control it.
In sum, Federal control of airplane noise performance continues to be per-
vasive, although allowing some room for state or local enforcement of noise
limits. Imposition of aircraft weight limits and interference with flight paths
generally are outside the scope of state and local noise regulation. As pro-
prietors of airports, however, localities may exert some control over hours of
operation and initiate other procedures to minimize noise in residential areas
that are non-discriminatory and not overly disruptive of interstate commerce.
That these latter activities have been allowed suggests that a more permissive
view of state and local airport noise regulation may be evolving.
Land use controls establishing permissible activities in zones of land
are well within state and local perogative. Thus, receiving land use
actions envisioned under Article VIII and X of the Model Ordinance [Appen--
dix C] are immune from any assertion of preemption.

roads, trucks, and buses, are covered by the Noise Control Act of 197210 and by

Environmental Protection Agency and Department of Transportation regulations.11
The preemptive character of Federal involvement in interstate carrier
noise regulation is as follows: state and local authorities are not permitted
to adopt or to enforce standards covering the same operations the Federal stand-
ards control unless those standards are identical to Federal standards, without
the EPA Administrator's approval. The Noise Control Act is explicit:12
No State or political subdivision thereof may adopt or enforce any
standard applicable to the same operation of such motor carrier,
unless such standard is identical to a standard applicable to noise
emissions resulting from such operation prescribed by any regulation
under this section.
(2) Nothing in this section shall diminish or enhance the rights
of any State or political subdivision thereof to establish and en-
force standards or controls on levels of environmental noise, or to
control, license, regulate, or restrict the use, operation, or move-
ment of any product if the Administrator, after consultation with the
Secretary of Transportation, determines that such standard, control,
license, regulation, or restriction is necessitated by special local
conditions and is not in conflict with regulations promulgated under
this section.
The above language applies to motor carriers but is nearly identical to the
rail carrier preemption section.13
EPA's approach to interstate carrier noise regulation leaves some flex-
ibility to state and local authorities to address site specific problems on a
11 EPA, after consulting with the Department of Transportation, is responsi-
ble for establishing noise emission standards for motor carriers. See
40 C.F.R. 202.10 et seq. These standards have been incorporated in
Table II of section 9.1 of the Model Ordinance (Appendix C). The Noise
Control Act places primary enforcement responsibilities on the Department
of Transportation. See 49 C.F.R. 325.1 et seq.

case-by-case basis, without Federal interference. On the one hand, where the
Federal government has established standards for interstate rail and motor
carriers, state and local authorities cannot adopt or enforce any standard, for
operations of the same equipment and facilities covered by the Federal standard,
unless it is identical with the Federal standard. On the other hand, where a
local situation demands a stricter noise regulation, EPA may permit state and
local authorities to establish and enforce such standards or controls and take
other necessary action provided there is no conflict with Federal regulation.
In this latter case, however, EPA must approve the contemplated action prior to
its taking effect.
Consolidated Rail Corp. v. City of Dover,^ illustrates one judicial re-
sponse to the preemption sections of the Noise Control Act. Here, the City of
Dover enacted an ordinance that prohibited "unnecessary and unusually loud
noise" in the context of railroad operation between the -hours of eleven p.m. and
seven a.m. which either "annoys, disturbs, injures or endangers...." Noting
that the comparable Federal standard was expressed in terms of decibels, the
court struck down the local ordinance as not "identical" and, therefore, pre-
empted by Federal law. Moreover, under the same rationale, the city was not
permitted to bring a common-law nuisance action for noise against the interstate
carrier-
Product Noise Control
Federal' preemption also touches products identified and regulated by EPA
as major sources of noise. The EPA administrator is authorized to proscribe
noise standards for products which fall into the categories of construction

-------
equipment, transportation equipment (including recreational vehicles), electric-
al or electronic equipment, and motors or engines, and which have been identified
by EPA as major sources of noise susceptible to feasible noise emission standards,
The preemption flows from the following provision of the Noise Control
Act:15
"Mo State or political subdivision thereof may adopt or enforce --
(A) with respect to any new product for which a regulation has
been prescribed by the Administrator under this section, any law or
regulation which sets a limit on noise emissions from such new product
and which is not identical to such regulation of the Administrator; or
(B) with respect to any component incorporated into such new
product by the manufacturer of such product, any law or regulation
setting a limit on noise emissions from such components when so in-
corporated.
(2) Subject to sections 4916 and 4917 of this title, nothing in this
section precludes or denies the right of any State or political sub-
division thereof to establish or enforce controls on environmental
noise (or one or more sources therof) through the licensing, regulation,
or restriction of the use, operation, or movement of any product or
combination of products.
To date, final standards for new product emission standards have been issued
for air compressors,^ medium and heavy duty trucks,1'' and truck mounted solid
waste compactors.^ EPA has also issued final labeling regulations for new
hearing protectors.19

EDP has issued proposed new product emission regulations for buses,20 motor-
cycles, 21 and wheel and crawler tractors.22
Conflicts may arise between Federal noise performance standards for products
and local environmental controls where the latter are so stringent as to exclude
the use of products which already have met Federal standards. However, such ex-
clusion would be appropriate and reasonable in areas such as hospital zones or
libraries, where operation of noise sources such as snowmobiles or motorcycles
is incompatible, regardless of the sound reduction achieved under Federal regula-
tions.
In addition, the Quiet Communities Act amended the Noise Control Act to
permit state and local jurisdictions to petition EPA to promulgate more stringent
new product emission standards.-23
Additional Federal sanctions against tampering with noise control devices
on regulated products are enforceable by states and localities.

GLOSSARY OF KEY TERMS
This glossary is designed to help the prosecutor understand key
terms that are likely to appear in noise violation prosecutions at some
point or other. The glossary selects and defines important terms from
the acoustical, medical, and engineering fields, drawing on the defini-
tions used in a number of EPA publications.* It also incorporates some
of the more generally applicable definitions used in the Model Community
Noise Control Ordinance. Terms unique to the Model Ordinance are
not repeated in the glossary but may be found in Appendix C (Article III)
, Public Health and Welfare Criteria for Noise, (1973); EPA, About
Sound, (1976); EPA, Workbook for Police Enforcement of Noise Regulations,
7T97B").

-------
A-WEIGHTED SOUND LEVEL -- An adjusted measure of sound pressure level.
The ear does not respond equally to all frequencies, but is less
efficient at low and high frequencies than at medium or speech
range frequencies. Thus, to obtain a single number representing
the sound level of a noise containing a wide range of frequencies
in a manner representative of the ear's response, it is necessary
to reduce the effects of the low and high frequencies with respect
to the medium frequencies. The resultant sound level is said to be
A-weighted, and the units are dB. A popular method of indicating
the A-weighted units is dBA or dB(A). The A-weighted sound level
is also called the noise level. Sound level meters have an A-
weighting network for measuring A-weighted sound level.
ABSORPTION -- A property of materials that allows th'ose materials to
reduce the amount of sound energy reflected. The introduction of
an "absorbent" into the surfaces of a room will reduce the sound
pressure level in that room by virtue of the fact that sound energy
striking the room surfaces will not be totally reflected. The
effect of absorption merely reduces the resultant sound level in
the room produced by energy that has already entered the room.
ABSORPTION COEFFICIENT -- A measure of the sound-absorbing ability of a
surface. This coefficient is defined as the fraction of incident
sound energy absorbed or otherwise not reflected by the surface.
Unless otherwise specified, a diffuse sound field is assumed. The
values of the sound-absorption coefficient usually range from
about 0.01 for marble slate to almost 1.0 for long absorbing wedges
such as are used in anechoic rooms.
ACOUSTICS -- (1) The science of sound, including the generation, trans-
mission, and effects of sound waves, both audible and inaudible.
(2) The physical qualities of a room or other enclosure (such as
size, shape, amount of noise) that determine the audibility and
perception of speech and music.
ACOUSTIC TRAUMA -- Damage to the hearing mechanism caused by a sudden
burst of intense noise, or by a blast. Note: The term usually
implies a single traumatic event.
AMBIENT SOUND LEVEL -- The noise associated with a given environment,
exclusive of the particular noise being tested, being usually a
composite of sounds from many sources near and far, exclusive of
intruding noises from isolated identified sources.
ANEMOMETER -- An instrument used to measure the wind speed at the test
site. The anemometer should have an accuracy of +_ 1.2 miles per
hour at true wind speeds of up to 12 miles per hour to be considered
reliable.
AUDIO FREQUENCIES -- The frequency of a sound wave within the normal
range of hearing, usually from 20 to 20,000 Hz.
A-2
-------
AUDIOGRAM — A graph showing hearing acuity as function of frequency.
AUDIOMETER -- An instrument for measuring hearing loss.
AURICLE (pinna) — The outer ear, including the opening to the ear
canal.
BACKGROUND NOISE -- The total of all noise in a system or situation,
independent of the presence of the desired signal. In acoustical
measurements, strictly speaking, the term "background noise" means
electrical noise in the measurement system. However, in popular
usage the term "background noise" is often used with the same
meaning as "residual noise." or "ambient sound level."
BAFFLE — A baffle is a shielding structure or series of partitions used
to increase the effective length of the external transmission path
between two points in an acoustic system.
BROADBAND NOISE -- Noise with components over a wide range of frequen-
cies.
C-WEIGHTED SOUND LEVEL (dBC) — A quantity, in decibels, read from a
standard sound-level meter that is switched to the weighting net-
work labeled "C". Occasionally used when there is reason to think
that the low frequency energy content of a source is being overly
discriminated against by low frequency roll-off of the A-weighted
filter.
COMMUNITY NOISE EQUIVALENT LEVEL — A scale (CNEL) that takes account
of all the A-weighted acoustic energy received at a point, from
all noise events causing noise levels above some prescribed value.
Weighting factors are included that place greater importance upon
noise events occurring during the evening hours (7:00 p.m. to
10:00 p.m.) and even greater importance upon noise events at night
(10:00 p.m. to 6:00 a.m.).
COMPOSITE NOISE RATING -- A scale (CNR) that takes account of the total-
ity of all aircraft operations at an airport in quantifying the
total airport noise environment. A CNR value is calculated by
beginning with a measure of the maximum noise magnitude from each
aircraft flyby and adding weighting factors that sum the cumulative
effects of all flights. The scale used to describe individual
noise events is perceived noise level (in PNdB); the term accounting
for number of flights is 10 log ]_QN. (where N is the number of
flight operations), and each night operation counts as much as 10
daytime operations. Very approximately, the noise exposure level
at a point expressed in the CNR scale will be numerically 35-37 dB
higher than if expressed in the CNEL scale.
CONTINUOUS SOUND SPECTRUM -- A sound spectrum composed of components
that are continuously distributed over a frequency region.
CYCLES PER SECOND -- A measure of frequency numerically equivalent to
Hertz.
A-3
-------
DAMPING -- The dissipation of energy with time or distance. The term
is generally applied to the attenuation of sound in a structure
owing to the internal sound-dissipative properties of the structure
or owing to the addition of sound-dissipative materials.
DAY-NIGHT AVERAGE SOUND LEVEL (Ldn) — The 24-hour energy average of
the A-weighted sound pressure level, with the levels during the
period 10:00 p.m. to 7:00 a.m. increased by 10 dBA before averaging.
DECIBEL — A measure (abbreviated "dB") on a logarithmic scale, of the
magnitude of a particular quantity (such as sound pressure, sound
power, intensity) with respect to a standard reference value (0.0002
microbars for sound pressure and 10-12 watt for sound power).
DOPPLER EFFECT (DOPPLER SHIFT) -- The apparent upward shift in frequency
of a sound as a noise source approaches the listener (or vice
versa), and the apparent downward shift when the noise source
recedes. The classic example is the change in pitch of a railroad
whistle as the locomotive approaches and passes by.
DOSIMETER -- An instrument which registers the occurrence and duration
of noise exceeding a predetermined level at a chosen point in the
envi ronment.
EFFECTIVE PERCEIVED NOISE LEVEL (EPNL) — A physical measure designed
to estimate the effective "noisiness" of a single noise event,
usually an aircraft fly-over; it is derived from instantaneous
Perceived Noise Level (PNL) values by applying corrections for
pure tones and for the duration of the noise.
EQUIVALENT A-WEIGHTED SOUND LEVEL (Leq) — The constant sound level
that, in a given situation and time period, conveys the same sound
energy as the actual time-varying A-weighted- sound.
FAR FIELD — Describes a sound source region in free space. At a suf-
ficient distance from the source, the sound pressure level obeys
the inverse-square law (the sound pressure decreases 6 dB with
each doubling of distance from the source). Also, the sound particle
velocity is in phase with the sound pressure. This region is
called the far field of the sound source. Regions closer to the
source, where these two conditions, do not hold, constitute the
near field. In an enclosure, as opposed to free space, there can
also sometimes be a far field region if there is not so much
reflected sound that the near field and the reverberant field
merge. See also, "reverberant field."
FREE SOUND FIELD (FREE FIELD) — A sound field in which the effects of
obstacles or boundaries on sound propagated in that field are
negligible.
FREQUENCY -- The number of times per second that the sine-wave of sound
repeats itself, or that the sine-wave of a vibrating object repeats
itself. Now expressed in Hertz (Hz), formerly in cycles per second
(cps).
A-4
-------
HAIR CELL — Sensory cells in the cochlea which transform the mechanical
disturbance of sound into a nerve impulse.
HEARING IMPAIRMENT -- Hearing loss exceeding a designated -criterion.
The Occupational Safety and Health Act defines as compensable
hearing loss 25-dB average hearing loss at 500, 1000, and 2000 Hz.
HEARING LOSS -- At a specified frequency, an amount, in decibels, by
which the threshold of audibility for that ear exceeds a certain
specified audiometric threshold, that is to say, the amount by
which a person's hearing is worse than some selected norm. The
norm may be the threshold established at some earlier time for
that ear, or the average threshold for some large population, or
the threshold selected by some standards setting body for audio-
metric measurements.
HERTZ — Unit of measurement (Hz) of frequency, numerically equal to
cycles per second.
IMPULSIVE SOUND -- Sound of short duration, usually less than one
second, with an abrupt onset and rapid decay. Examples of sources
of impulsive sound include explosions, drop forge impacts, and
the discharge of firearms.
INFRASONIC -- Sounds of a frequency below the audiofrequency range.
INVERSE-SQUARE LAW -- A description of acoustic wave behavior in which
the meansquare pressure varies inversely with the square of the
distance from the source; this behavior usually occurs in free-field
situations, so that the sound level decreases 6 dB wih each doubling
of distance from the source.
LEVEL — The logarithm of the ratio of a sound pressure being measured
to a reference sound pressure when expressed in decibels.
LINE SPECTRUM -- The spectrum of a sound whose components occur at a
number of discrete frequencies.
LOUDNESS — The judgment of intensity of a sound by a human being.
Loudness depends upon the sound pressure and freqency of the
stimulus. Over much of the frequency range it takes about a
threefold increase in sound pressure (approximately 10 dB) to
produce a doubling of loudness.
NEAR FIELD -- The sound field very near to a source, where the sound
pressure does not obey the inverse-square law; see "far field."
NOISE -- Any sound which annoys or disturbs humans or which causes or
tends to cause an adverse psychological or physiological effect on
humans.
NOISE DISTURBANCE -- Any sound which (a) endangers or injures the safety
or health of humans or animals, or (b) annoys or disturbs a reasonable
person of normal sensitivities, or (c) endangers or injures personal
or real property.
A-5
-------
NOISE EXPOSURE FORECAST -- A scale (analogous to CNEL and CNR) that has
been used by the Federal government in land use planning guides
for use in connection with airports. In the NEF scale, the basic
measure of magnitude for individual noise events is the effective
perceived noise level (EPNL), in units of EPNdB. This magnitude
measure includes the effect of duration per event. The terms
accounting for number of flights and for weighting by. time period
are the same as in the CNR scale.
OCTAVE -- The interval between two sounds having a basic frequency
ration of two. For example, there are 8 octaves on the keyboard
of a standard piano.
OCTAVE BAND -- All of the components, in a sound spectrum, whose fre-
quencies are between two sine-wave components separated by an
octave.
PERCEIVED NOISE LEVEL (PNL) -- A quantity expressed in decibels that
provides a subjective assessment of the perceived "noisiness" of
aircraft noise. The units of Perceived Noise Level are Perceived
Noise Decibels, PNdB.
PNdB -- See perceived noise level.
PRESBYCUSIS — Impaired hearing due to old age.
PURE TONE -- Any sound which can be distinctly heard as a single pitch.
*
REFRACTION — A bending of the direction of travel and sound wave from
its established path, caused, for example, by a wind, a barrier, or
a temperature gradient.
RESIDUAL NOISE LEVEL -- The noise that exists at a point as a result of
the combination of many distinct sources, individually indistinguish-
able. In statistical terms, it is the level that exists 90 percent
of the time. In popular usage the term "residual noise" is often
used interchangeably with "ambient noise." See also, "background
noise."
REVERBERANT FIELD -- A sound field in which sound is significantly
affected by obstacles, reflecting surfaces, and boundaries, charac-
terized by multiple echoes; the opposite of "free field."
ROOT-MEAN-SQUARE (RMS) — A term describing the mathematical process to
determine an "average" value of a complex signal.
SHIELDING -- The attenuation of a sound by placing walls, buildings, or
other barriers between a sound source and the receiver.
SONE -- The unit of measurement for loudness. One sone is the loudness
of a sound whose level is 40 phons.
A-6
-------
SONIC BOOM -- The pressure transient produced at an observing point by
a vehicle that is moving past (or over) it faster than the speed
of sound.
SOUND -- An oscillation in pressure, particle displacement, particle
velocity or other physical parameter, in a medium with internal
forces that causes compression and rarefaction of that medium.
The description of sound may include any characteristic of such
sound, including duration, intensity and frequency.
SOUND INSULATION -- (1) The use of structures and materials designed to
reduce the transmission of sound from one room or area to another
or from the exterior to the interior of a building. (2) The degree
by which sound transmission is reduced by means of sound insulating
structures and materials.
SOUND LEVEL -- The weighted sound pressure level obtained by the use of
a sound level meter and frequency weighting network, such as A, B,
or C as specified in American National Standards Institute specifi-
cations for sound level meters (ANSI SI.4-1971, or the latest
approved revision). If the frequency weighting employed is not
indicated, the A-weighting is implied.
SOUND LEVEL METER -- An instrument which includes a microphone, ampli-
fier, RMS detector, integrator or time averager, output meter, and
weighting networks used to measure sound pressure levels.
SOUND PRESSURE -- The instantaneous difference between the actual pres-
sure and the average or barometric pressure at a given point in
space, as produced by sound energy.
SOUND PRESSURE LEVEL -- The root-mean-square value of sound pressure,
expressed as the logarithm of the ratio of that sound pressure to
a reference sound pressure (20 microPascals) in decibels (dB).
SPEED (VELOCITY) OF SOUND IN AIR -- The speed of sound in air is 344
m/sec or 1128 ft/sec at 78 degrees F.
STEADY-STATE SOUNDS -- Sounds whose average characteristics remain
reasonably constant in time. An example of a steady-state sound
is an air conditioning unit.
TEMPORARY THRESHOLD SHIFT (TTS) — A temporary impairment of hearing
capability as indicated by an increase in the threshold of audibil-
ity. By definition, the ear recovers after a given period of time.
Sufficient exposures to noise of sufficient intensity, from which
the ear never completely recovers, will lead to a permanent threshold
shift (.PTS), which constitutes hearing loss.
TINNITUS -- Ringing in the ear or noise sensed in the head. Onset may
be due to. noise exposure and persist after a causative noise has
ceased or occur in the absence of acoustical stimulation (in which
case it may indicate a lesion of the auditory system).
A-7
-------
TONE -- A sound of definite pitch. A pure tone has a sinusoidal wave
form.
WAVELENGTH -- For a periodic wave (such as sound in air), the perpendic-
ular distance between analogous points on any two successive waves.
The wavelength of sound in air or in water is inversely proportional
to the frequency of the sound. Thus, the lower the frequency, the
longer the wavelength.
WINDSCREEN -- A porous device to cover the microphone of a sound level
measurement system and intended to minimize the affects of winds and wind
gusts on the sound levels being measured; typically made of reticulated
(open cell) polyurethane foam and spherical in shape.

INTRODUCTION
Purpose
The Model Community Noise Control
Ordinance (model ordinance) is intended
to b« a basic tool which communities, both
large and small, can use lo construct noise
control ordinances suited to local needs and
conditions. The complete model ordinance,
including optional provisions, is perhaps
most suitable for larger communities, with
populations of about 100,000 or more.
Smaller communities and large communities
with limited resources may wish to adopt
only those provisions which address their
most pressing noise problems. It is impor-
tant that the community ensure that all
provisions adopted are realistic in relation
to local needs and conditions; that all pro-
visions are consistent with one another, with
other local law, and with State and Fed-
eral law; and. finally, that all provisions are
clear and otherwise well drafted so that
enforcement problems will be minimized.
Background
This model ordinance is an outgrowth of
the Federal Noise Control Act of 1972 (49
U.S.C. §§ 4901 et seq-.) and the tremen-
dous increase in interest regarding noise
abatement and control which the Act has
precipitated. Many existing community
noise ordinances are based on outmoded
model ordinances and/or the common law
approach to noise control which relies ex-
clusively on difficult to enforce nuisance
provisions. While the model ordinance pre-
serves common law with Article VI provi-
sions prohibiting noise disturbances, it also
contains definitive performance standards
for motor vehicles and other sources of
community noise. The increase in reliable
monitoring equipment available to local gov-
ernments, coupled with definitive standards
incorporated into local noise control ordi-
nances, should result in ordinances which
are more easily enforceable than many have
been in the past.
It is anticipated that an anaiagous model
ordinance will form pan of a workbook on
community noise abatement and control to
be published by the U.S. Environmental
Protection Agency during late 1977. In ad-
dition to containing the model ordinance
(perhaps with discussions of a number of
alternative provisions), the workbook may
contain chapters on the legal basis of noise
control, the health effects of noise and vari-
ous enforcement approaches.
Although the model ordinance will stand
alone as a legal document, for proper en-
forcement the City/County must additional-
ly have a code of recommended practices or
rules and regulations which give general
specifications for sound measuring equip-
ment and measurement methodology. This
document should al.so provide detailed pro-
cedures for measurements to be taken for
certain provisions of the ordinance, such as
motor vehicles and stationary sources. To
assist communities in the development of a
code of recommended practices, EPA is pre-
paring a model code which, when completed.
will be sent to recipients of the model
ordinance.
Interrelationship of Various
Provisions
An overview of the mcdel ordinance can
most readily be obtained hy reading the
List of Provisions. When a community de-
termines which activities it wishes to regu-
late, the appropriate model provision i.r pro-
visions can be located bv referring to this
list.
A glance through the List of HrovisK-ns
suggests that certain acts may be prohihi'ed
jy more than one provision. For
use of a noisy go-can couUl violate Sii
9.2 ("Recreational Vehicles Operating Off
Public Rights-Of-Way"), as wcil as Section
6.1 (Noise Disturbances) It may be that d
community desires such muitipls icverrg-:.
In this case, enforcement against the owner
or operator of a noisy go-cart would prob-
ably come under the provision more easily
enforced, but could come under both pro-
visions violated, at the discretion of the en-
forcement agency If a community, does not
desire such multiple coverage, it can either
omit certain provisions or it can exempt
acts covered by other provisions from mul-
tiple coverage. Such modifications deserve
careful consideration, however, jo that they
do not modify the ordinance more than
desired or otherwise jeopardize enforcement.
GENERAL PROVISIONS
Policy Regarding Levels
In this model ordinance, recommended
values for sound levels in the performance
standards have been omitted in most cases.
Suggested times for the curfews on the
hours of the conduct of activities or the op-
eration of equipment have also generally
been omitted. The reason for these omis-
sions is that the drafters of the ordinance
feel that there is no single number that can
be chosen for each provision that would be
appropriate for all types of communities.
Each community has its own set of environ-
mental, health, economic and other goals
it wishes to attain. Each community also has
its own configuration of noise sources and
their impact which it wishes to control. The
level and e.Ttent of such control is fully
wuhin the purview of local decision. Of
course, localities will wish to consider the

ableness of sound levels chosen. However, in
the regulation of noise pollution, the protec-
tion of public health and welfare is the ma-
jor legal basis for control and must be care-
fully considered in the determination of per-
formance standard noise levels and hours of
curfew. For a specification of national maxi-
mum noise exposure guidelines, consult In-
formation on the Levels of Environmental
,Vorr« Requisite to Protect Public Health
and Welfare with an Adequate Margin of
Safety (U.S. Environmental Protection
Agency, March 1974).
Pre-Emption
Under the Noise Control Act of 1972 (49
U.S.C. §§ 4901 et ;eq.), certain areas of lo-
cal authority will become pre-empted on
the effective date of regulations developed
by the U.S. Environmental Protection
Agency pursuant to Sections 6. 17 and 18
of this Act. In this discussion, we will pre-
sent the scope of Federal pre-emption and
indicate the provisions of the model ordi-
nance which were drafted wholly or par-
tially to respond to the issue of pre-emption.
An over-all requirement to monitor Fed-
eral pre-emptive regulations and to respond
to them in the local noise ordinance is con-
tained in Section 4.3.6(b). This subsection
provides that, at such time as Federal regu-
lations become effective which are by law
pre-emptive of the laws of State and local
government, the Environmental Protection
Officer(r)/Noise Control Office(r) (EPO/
NCO) shall review the provisions of the lo-
cal ordinance which may be affected and
make appropriate recommendations for
changes to the city council/legislative body.
The purposes of including such a provi-
sion in this ordinance are to facilitate the
coordination of the local noise control ef-
forts with the Federal noise program and
to reduce the possibility of defendants rais-
ing Federal pre-emption as a defense to
charges of local law violations.
With regard to the scope of pre-emption,
the pre-emptive provision of Section 6 of
the Noise Control Act differs considerably
from those of Sections 17 and 18. The Sec-
tion 6 provision is relatively narrow, pre-
empting local laws covering new product
noise emission levels which are directed at
the manufacture or sale of such products.
The preemptive provisions of Sections 17
and 18 are very broad, pre-empting local
noise laws which affect the operation of in-
terstate motor and rail carrier vehicles.
In Section 6, subsection 6(e)(l) provides
that, after the effective date of an EPA
regulation prescribing noise emission levels
for a specific new product or component,
no State or political subdivision thereof may
adopt or enforce with respect to that par-
ticular new product or component any law
or regulation which sets a noise emission
limit on such product (or component) en-
forceable against the manufacturer of the
product, applicable at the time of sale, un-
less such law or regulation is identical to
the Federal regulation. Thus, the preemp-
tion is against State and local laws which
regulate the noise levels of a new product
(i.e.. a product which has not yet been sold
to the first retail purchaser) and which, at
any time, impact the manufacturer of the
product.
State and local governments, under sub-
section 6(e)(2), retain authority to control
products by all other available means. This
subsection states that nothing in this sec-
tion precludes or denies the right of State
or local governments to establish and en-
force controls on environmental noise and
sources thereof through the licensing, regu-
lation, or restriction of the use, operation or
movement of any product or combination of
products.
Thus, although a local government may
not enforce a non-identical local law regard-
ing the noise level of an EPA-regulated new
product which affects the manufacture or
sale of such product, the local government
may regulate the product noise impact
through regulations enforceable against the
owner or operator of the product by pro-
viding, for example, maximum noise levels
for operation, curfews on operation, pro-
hibition of use in a residential neighbor-
hood or hospital zone, or requirements for
periodic inspection and licensing of the
product.
Broader pre-emptive coverage is found in
Sections 17(c)(l) and 18(c)(l). These sec-
tions provide that, after the effective date
of an EPA regulation applicable to noise
emissions from interstate rail or motor car-
riers, no State or political subdivision there-
of may adopt or enforce any standard ap-
plicable to the same noise source unless
such standard is identical to the Federal
standard. However, Sections 17 (c) (2) and
18(c)(2) provide thai nothing in these sec-
tions shall diminish or enhance the right
of State and local governments to establish
and enforce standards or controls on levels
of environmental noise or to control, license,
regulate or restrict the use,, operation or
movement of any regulated product if two
conditions occur:
1) the EPA Administrator, after consul-
tation with the Secretary of the Department
of Transportation, determines that such lo-
cal law is necessitated by special local con-
ditions, and
2) if he determines that such local law
is not in conflict with the EPA regulations.
Thus, on the effective date of the EPA
rezulations under Section 18 (October 15,
C-3
-------
1975) and Section 17 (undetermined as yet).
local governments should review any ordi-
nance provisions applicable to noise emis-
sions resulting from the use or operation of
motor vehicles with a gross veh'-'.s or com-
bination weight rating of greater than 10,000
Ibs. operated by an interstate motor carrier
and of interstate surface railroad locomo-
tives and cars. Local regulations providing
standards on noise emissions resulting from
operations subject to Federal regulations
must be identical to the Federal regulation.
Such identity applies not only to the stand-
ard but also to the core measurement meth-
odology which defines the standard. Non-
identicnl standards may not be enforced, and
should be declared ineffective, as of the ef-
fective date of the Federal regulation. For
this reason. Section IS standards have been
incorporated into Table II of Section 9.1 in
the model ordinance. The appropriate meas-
urement methodology should be incorpo-
rated intu the community code of recom-
mended practices.
In general, we can classify the pre-emp-
tive effect of these sections on local law
into three categories. First, any local law
\\hich sets noise emission levels for inter-
state motor vehicles and rail locomotives
and cars must be identical to the Federal
standard. Xo special local condition or other
factor can exempt this requirement. Second,
local laws which regulate or restrict the use,
operation, or movement of interstate motor
rail carriers by such means as curfews and
truck routes (see Section 4.3.4, Truck
Routes and Transportation Planning) will
not be subject to pre-emption if (1) the
principal purpose of such regulation is not
to control noise, or (2) the principal pur-
pose is to control noise but the regulation
has been approved by the EPA as necessi-
tated by special local conditions and not in
conflict with Federal regulations. For ex-
ample, truck routes designated solely on
the basis of noise must be submitted to EPA
for determination of a special local condi-
tion. Truck routes based on additional fac-
tors, such as the safety of children, maxi-
mum load, on street surfaces, etc., will
not need EPA approval Third, general
noise regulations, such as the property line
noise emission standards of Article VIII,
will not be affected by these pre-emption
provisions except in rare cases. Thus, the
property line levels may be applied to noise
emissions caused by interstate motor car-
rier vehicles at a loading terminal so long-
as means of abatement are possible which
do not require controlling the noise emis-
sion level of the motor vehicle itself. Such
other means of abatement can include, for
example, installation of noise barriers at the
perimeter of the terminal and creation of
buffer zones of land between the terminal
and the noise-impacted areas.
Hearing Board and Advisory
Council
A City/County with a large EPO/NCO
may prefer to utilize a Hearing Board (or
an administrative court) to hear cases re-
garding ordinance violations. Under this ap-
proach, the Hearing Board would decide the
case and determine the penalty. Local courts
would be utilized in appeals of the deci-
sions of the board. This approach avoids
overburdening existing courts.
The City/County may also wish to use a
Hearing Board to make determinations on
Special Variances (Section 7.?"/ and Vari-
ances for Time to Comply (.Section 7.3).
This would free EPO/NCO personnel to per-
form other tasks under (he ordinance. How-
ever, the EPO/NCO could still be consulted
on technical matters.
If the City/County decides to have a
Hearing Board, the terms of existence and
operation of the Board should be specified
in the ordinance.
A Noise Control Advisory Council should
also be considered by the City/County. The
functions of this council could include pro-
viding (1) advice on development of the
noise control program; (2) recommenda-
tions on which provisions of the model ordi-
nance should be included in the City/
County ordinance; (3) recommendations on
sound level values and curfew periods for
the various provisions; and (4) stimulation
of public interest on noise abatem«nt. This
Council could .also be responsible for writ-
ing the periodic reports, specified in Section
4.3.9, concerning the progress of the local
noise control program.
SPECIFIC PROVISIONS
Article III—Definitions
1. Section 3.2.16, Definition ot "Motorboaf
A community which serves as an interna-
tional port may wish to explicitly exclude
vessels in international commerce from the
definition of motorboat. since many such
vessels would be effectively prohibited from
using the port (under Section 6.2.15, Motor-
boats).
2. Section 3.2.29, Definition of "Sound"
The term "sound" is generally used as
the operative word in this ordinance rather
than- the term "noise." This is to avoid the
problem of associating "noise" with a sound
that is "disturbing" or "unwanted", with
the attendant possibility that in order to
prove a violation of the ordinance, proof
must be given trial the sound had indeed
been "disturbing" or "unwanted." Because
the substantive provisions of the ordinance
have been narrowly drawn and often con-
tain objective criteria, proof of an addi-
tional subjective element is unnecessary.
C-4
-------
3. Section 3.2.22, Definition of "Person"
The definition of person does not include
Federal agencies and departments. This is
because legal decisions have not yet deter-
mined th« extent of a locality's authority
10 bring action against the Federal govern-
ment for noise control violations.
Section 4 of the Noise Control Act of
1972 requires that all departments, agen-
cies, and instrumentalities of the executive
legislative, and judical branches of the Fed-
eral Government comply with Federal,
State, interstate, and local requirements re-
specting control and abatement of environ-
mental noise to the same extent that any
person is subject to such requirements The
Federal Courts of Appeals, deciding cases
under identical language in the Gean Air
Act, have disagreed as to whether this
language extends to administrative as well
as substantive requirements. See State of
Alabama v. Seeber, 502 F. 24. 1238 (5 Cir.
1974); Commonwealth of Kentucky v.
Kuckehiiaus. 497 F. Id. 1172, (6 Cir. 1974).
Kentucky v. Ruckelshaui is pending before
the Supreme Court, and a resolution of the
issue is likely. Further questions exist is to
whether a State or local government can
bring an action against the Federal Gov-
ernment for violations of their noise con-
trol laws, regulations and ordinances. Ac-
cordingly, the key definition of "person" in
the model ordinance, which serves as an
applicability section, does not include the
Federal Government.
Sn the absence of such specificity, Sec-
lion 4 of the Noise Control Act continues
so require that the Federal Government
comply with the local ordinance. However,
it is left to each community to determine
the position it will take with respect to the
relevant issues, juch as whether the Fed-
eral Government must comply with ad-
ministrative provisions, and whether penal-
ties, orders, and enforcement actions will
be directed at the Federal Government un-
der Article XI (Enforcement).
Article IV—Powers and Duties
of The (Environmental Protec-
tion)/(Noise Control) Office(r)
Resolving Inter-Departmental Conflict]
Section 4.2.4 (Review of Actions of Other
Departments): Section 4.2.5 (Review of
Public and Private Projects). Section 4.3.4
(Truck Routes and Transportation Plan-
ning) and Article V (Duties and Respon-
sibilities of other Departments) have the
potential of causing inter-departmental uon-
flicts since there is shared responsibility. The
community may wish to specify in the ordi-
nance a method for resolving such con-
flicts, perhaps by authorizing the city coun-
cil, county board of supervisors, mayor, etc..
to negotiate differences and make a
decision.
Education
Section 4.2.2 authorizes the Environment-
al Protection (Noise Control) Office (r) to
educate the public on methods of control-
ling noise and on the provisions of the ordi-
nance. The EPO may wish to exercise cau-
tion, however, in providing specific advice
on solving a particular noise problem. For
instance, if the EPO were to advise a com-
mercial establishment on a method of re-
ducing noise from its air conditioning unit
ind this method failed to be effective, the
commercial establishment may try to use
this fact as a defense in any action brought
against it by the EPO. The EPO officer
should use his discretion in handling mat-
ters of this type.
Review of Public and Prfrate Projects
Section 4.2.5 grants the EPO the power
to review public and private projects over
which another department has authority in
order to determine whether they will com-
ply with the ordinance. This applies to such
matters as licensing a race track, approv-
iny a housing project, or granting a permit
for a construction site, if required to be ap-
proved by a department other than that of
the EPO/NCO and if likely to create sound
levels or sound exposures in vi6lation of the
ordinance.
Some communities may wish to exparjd
this section to authorize the EPO to rec-
ommend to other departments appropriate
modifications to projects if the EPO believes
such projects will violate the ordinance- or
to allow him veto power over projects sig-
nificantly impacting the noise environment.
This provision does not set criteria for
determining whether a proposed project
must be reviewed by the EPO/NCO. If the
City/County wishes the EPO/NCO to re-
view every proposed project, such criteria
are not necessary, but this policy may create
an unnecessarily large burden on. the EPO/
NCO. If the City/County wishes to limit
situations where the proposed project is sub-
ject to noise impact review, criteria can be
either included in the language of this pro-
vision, or the EPO/NCO can develop cri-
teria in consultation with affected depart-
ments. Such criteria may include, for ex-
ample, minimum monetary or time limits
for the review of activities or specification
of the types of activities which are likely to
produce sound in violation of the ordinance.
Inspections
Section 4.2.6 concerns inspections. To be
constitutionally permissible, administrative
searches or inspections conducted by muni-
cipal inspectors on private property must be
made using i warrant procedure (Camara
v. Municipal Court, 337 U.S. 523 (196T);
C-5
-------
See v. Seattle. 387 U.S. 511 (1967)). Thus,
if a private property holder refuses to allow
his premises to be inspected by a City/
County official, the official must obtain a
search warrant for the premises before he
may inspect them. The .Court in See also
held that there is no distinction between
the rights of a residential property holder
and those of a commercial property holder
concerning searches or inspections. Both
types of property are thus treated the same
in Section 4.2.6(a).
Violations of Article VIII (Noise Levels
by Receiving Land Use) and most Article
VI (.Prohibited Acts; violations can be de-
termined without an inspection on the
premises on which the sound source is situ-
ated, so a search warrant is not needed in
these situations.
Article VIII—Sound Levels by
Receiving Land Use (Defining
Land Use Districts)
Article VU1 sets property line sound kmits
for the broad receiving land use categories
of residential, commercial and industrial
Many communities are employing this type
of quantitative limit to provide stronger
fegai control over undesirable sound levels
than is attainable with an ordinance con-
taining only nuisance provisions.
If the community land use/zoning code
accurately reflects the actual use of the land.
then the designations used by the city for
zoning categories may effectively be plugged
into the three Article VIII categories (with
the corresponding definitions placed in Ar-
ticle III). On the other hand, if there arc
numerous discrepancies between the way the
land is zoned and the way it is actually used
(e.g.. commercial establishments in a resi-
dential zone), or if there are large tracts
of unzoned land, the community may pre-
fer to base property line limits on the actual
use of the land. This would provide greater
protection for impacted properties.
A related matter to be considered in con-
trolling property line noise is that of the oc-
casional non-conforming land use. An ex-
ample is the case of a single residence lo-
cated in an industrial area. It may not b*
possible for several manufacturers impact-
ing the residence to lower their noise levels
tt meet the limit specified for residential
B»es. Situations of this type will require
tMpc discretion in enforcement
Figures i, II, and III summarize grapm-
cally the property line levels set .by current
municipal noise ordinances.

Article X—Land Use
Uic h.iMC purpose of the Article X land
n^o planning provisions is to ensure that no
new residences, institutions or recreational
areas are constructed in high noise areas.
as determined by the appropriate sections.
Although the Article was drafted to stand
independently from the existing community
land use planning or zoning systems, it is
-------
important for a community considering en-
actment of this Article to study the inter-
action of Article X with the land use plan-
ning and/or zoning laws and to reconcile
them svhere necessary. It may be better, for
example, to enact Article X as an amend-
ment to an existing land use law rather than
as a pan of the noise control ordinance.
Furthermore, because this Article effective-
ly rezones land subject to its provisions, the
community may want or need to take spe-
cial measures before enactment of this Ar-
ticle. These may include a general identifica-
tion of rhe areas that \vill be affected by
these provisions.
Article XI—Enforcement
Provisions in this Article are more likely
to need revision to conform with local law
than other provisions of the model ordi-
nance. For example, the City/County may
wish to make violations of the ordinance
"infractions." similar to minor traffic viola-
tions, rather than misdemeanors, due to the
stigma attached to such violations.
The City/ Countv may »ish to ensure that
the public is reasonably well-informed of ac-
tivities prohibited by the ordinance before
fully effectuating its enforcement program.
For example, the City/County may utilize
a discretionary policy of issuing an abate-
ment order fur a first violation, followed by
a citation for the original violation, if the
abatement order is not complied uuh. This.
approach is provided for in Section 11.2
(Abatement Order), and would be used for
violations that are presumed to be unin-
tentional. The EPO/NCO may wish to
establish guidelines for use of the abate-
ment order, indicating, for example, ap-
propriate types of violations for which an
order may be issued and maximum time
period of an order.
The enforcement scheme contained in
this ordinance also includes a provision for
citizen suits (Section 11.5). The advantage
of the citi?en suit approach is that many
violations of the ordinance which the EPO.
NCO has insufficient resources to prosecute
can be legally dealt with by persons affected
by the violation. Provisions under which
one citizen can sue another are limited to
those listed in Table VI, to minimize the
possibility of "harassment" suits.
Section 11.3 (Notice- of Violation) is in-
complete in several respects for easy adapta-
tion to the local law of the particular City/
County.
Section 11.4 (Immediate Threats to
Health and Welfare) provides the EPO/
NCO with the authority to force immediate
abatement of sources producing sound in-
tensities that not only violate the ordinance
but are also unquestionably harmful to the
health of the public exposed to them. The
levels regulated (see Tables IV and
V) are deliberately set high, because there
is no procedure in this provision for balanc-
ing public health with economic or other
considerations; public health is the sole de-
terminant. The health and welfare criterion
for the levels set is a temporary threshold
shift of 30'dB at 4 kHz.
Subsection (b) limits the applicability of
this provision to impacts on members of the
general public who are involuntarily exposed
to the sound. Employee exposures at their
workplace are exempted because employee
sound exposure levels are regulated under
the Occupational Safety and Health Act
C9 U.S.C. §§ 669 et seq. (1970)).
Severe sanctions for noncompliance with
the order are provided for in subsection
(d). so that the sound will not continue to
be a detriment to public health. If the
order is unjustified, a court can invalidate
or suspend :t soon after the order is issued,
in a mandamus type proceeding. This
remedy is contained in subsection (e), which
may need to be modified to conform with
local procedure.
Under Section 11.6 (Other Remedies),
common law and statutory remedies previ-
ously used to regulate excessive sound will
still remain available. It is desirable to re-
tain such remedies to allow private persons
the possibility of recovering damages or
other remedies for the effects of excessive
sound since private recovery is not pro-
vided for under the ordinance. The ordi-
nance is intended to expand existing sound
control law. not to limit it.
FORMAT
[n reading the model" ordinance_ it is
essential that certain typographical symbols
and format be understood. Several brief
rules have been followed in drafting. These
are:
• The material contained in square brack-
ets [ ] is optional, depending on the
needs and conditions of a given community.
(Of course, communities developing ordi-
nances may decide that any given provision
should be deleted.)
• Parenthesis ( ) are generally used to
designate alternative choices, but in some
cases contain explanatory information, de-
pending on the context.
• Blanks must be filled in by the com-
munity with appropriate information.
• Wherever the term EPO/NCO appears,
the title of the community's lead noise en-
forcement agency or official should be in-
serted.

formance of emergency work.
7.2 Special Variances
(a) The (EPO/NCO)/(Hearing
Board) shall have the authority, con-
sistent with this section, to grant
special variances which may be re-
quested pursuant to Sections 6.2.6
(Construction) and 6.2.10 (Explo-
sives, Firearms, and Similar Devices).
(b) Any person seeking a special
variance pursuant to this section shall
file an application with the (EPO/
NCO)/(Hearing Board). The appli-
cation shall contain information
which demonstrates that bringing the
source of sound or activity for which
the special variance is sought into
compliance with this ordinance would
constitute an unreasonable hardship
on the applicant, on the community,
or on other persons. [Notice of an
application for a special variance
shall be published according to (juris-
dictional procedure).] Any individual
who claims to be adversely affected by
allowance of the special variance may
file a statement with the (EPO/
NCO)/(Hearing Board) containing
.my information to support his claim.
If'the (EPO/NCO)/(Hearing Board)
finds that a sufficient controversy
exists regarding an application, a pub-
lic hearing may be held.
(c) In determining whether to grant
or deny the application, the (EPO/
NCO)/(Hearing Board) shall balance
[he hardship to the applicant, the
community, and other persons of not
granting the special variance against
the adverse impact on the health,
safety, and welfare of persons
affected, the adverse impact on prop-
erty affected, and any other adverse
impacts of granting the special vari-
ance. Applicants for special variances
and persons contesting special vari-
ances may be required to submit any
information the (EPO/NCO)/(Hear-
ing Board; may reasonably require. In
granting or denying an application,
the (EPO/NCO)/(Hearing Board)
shall place on public file a copy of
the decision and the reasons for deny-
ing or granting the special variance.
(d) Special variances shall be granted
by notice to the applicant containing
all necessary conditions, including a
time limit on the permitted activity.
The- special variance shall not be-
come effective until all conditions are
agreed to by the applicant. Noncom-
piiance with any condition of the
special variance shall terminate it and
subject the person holding it to those
provisions of this ordinance regulating
the source of sound or activity for
C-18
-------
which the special variance was
granted.
(e) Application for extension of time
limits specified in special variances or
for modification of other substantial
conditions shall be treated like appli-
cations for initial special variances
under subsection (b).
(0 The (EPO/NCO)/ (Hearing
Board) may issue guidelines [ap-
proved by ] defining
the procedures to be followed in
applying for a special variance and
the criteria to be considered in decid-
ing whether to grant a special vari-
ance.
7_3 Variances for Time to Comply

effective date of this ordinance, the
owner of any commercial or industrial
source of sound may apply to the
(EPO/NCO)/(Hearing Board) for a
variance in time to comply with Sec-
tion 6... 12 (Vibration) or Article
VIII. The (EPO/NCO)/(Hearing
Board) shall have the authority, con-
sistent with this section, to grant a.
variance, not to exceed days
from, the effective date of this ordi-
nance.
(b) Any person seeking a variance in
time to comply shall file an applica-'
tion with the (EPO/NCO.)/ (Hearing
Board). The application shall contain
information which demonstrates' that
bringing the source of sound or activ-
ity for which the variance is sought
into compliance with this ordinance
prior to the date requested in the
application would constitute an un-
reasonable hardship on the applicant,
on the community, or on other per-
sons. [Notice of an application for a
variance in time to comply shall be
published according to (jurisdictional
procedure).] Any individual who
claims to be adversely affected by
allowance of the variance in time to
comply may file a statement with the
(EPO/N'CO)/(Hearing Board) con-
tainina any information to support
his claim. If the (EPO/NCO)/ (Hear-
ing Board) finds that a sufficient con-
troversy exists regarding an applica-
tion, a public hearing may be held.
(c) In determining whether to grant
or deny the application, the (EPO/
NCO)/ (Hearing Board) shall balance
the. hardship to the applicant, the
community, and other persons of not
granting the variance in time to com-
ply against the adverse impact on
health, safety, and welfare of persons
affected, the adverse impact on prop-
erty affected, and any other adverse
impacts of granting the variance.
Applicants for variances in time to
comply and persons contesting vari-
ances may be required to submit
any information the (EPO/NCO)/
(Hearing Board) may reasonably re-
quire. In granting or denying an ap-
plication, the (EPO/NCO)/(Hearing
Board) shall place on public file a
copy of the decision and the reasons
for denying or granting the variance
in time to comply.
fd) Variances in time to comply shall
be granted to the applicant contain-
ing all necessary conditions, including
a schedule for achieving compliance.
The variance in time to comply shall
not become effective until all condi-
tions are agreed to by the applicant.
Noncompliance with any condition of
the variance shall terminate the vari-
ance and subject the person holding
it to those provisions of this ordinance
for which the variance was granted.
(e) Application for extension of time
limits specified in variances in time
to comply or for modification of other
substantial conditions shall be treated
like applications for initial variances
under subsection (b), except that the
(EPO/NCO)/(Hearing Board) must
find that the need for the extension
or modification clearly outweighs any
adverse impacts of granting the exten-
, sion or modification..
(f) The (EPO/NCO)/(Hearing
Board) may issue guidelines [ap-
proved by ] defining
the procedures to- be followed in
applying for a variance in time to
comply and the criteria to be con-
sidered in deciding whether to grant
a variance.
7.4 Appeals
Appeals of an adverse decision of the
(EPO/NCO)/(Hearing Board) shall
be made to the (appropriate court of
law). Review of the court shall be
(de novo)/ (limited to whether the
decision is supported by substantial
evidence)/(as specified by the ....

(b) The Congress declares that it is the policy of the United States
to promote an environment for all Americans free from noise that
jeopardizes their health or welfare. To that end, it is the puroose of
this Act to establish a means for effective coordination of Federal
research and activities in noise control, to authorize the establishment
of Federal noise emission standards for products distributed hi com-
merce, and to provide information to the public respecting the noise
emission and noise reduction characteristics of such products.

(1) having jurisdiction over any property or facility, or
(2) engaged in any activity resulting, or which may result, in
the emission of noise,
shall comply with Federal, State, interstate, and local requirements
respecting control and abatement of environmental noise to the same
extent that any person is subject to such requirements. The President
may exempt any single activity or facility, including noise emission
sources or classes thereof, of any department, agency, or instrumen-
tality in the executive branch from compliance with any such require-
ment if he determines it to be in the paramount interest of the United
States to do so: except that no exemption, other than for those
products referred to in section 3(3) (B) of this Act. may be granted
from the requirements of sections 6. 17, and 18 of this Act. Xo such
exemption shall be granted due to lack of appropriation unless the
President shall have specifically requested such appropriation as a
part of the budgetary process and the Congress shall have failed to
make available such requested appropriation. Any exemption shall
be for a period not in excess of one year, but additional exemptions
may be granted for periods of not to exceed one year upon the
President's making a new determination. The President shall report

Federal agencies relating to noise research and noise control. Each
Federal agency shall, upon request, furnish to the Administrator such
information as he may reasonably require to determine the nature,
scope, and results of the noise-research and noise-control programs of
the agency.
(2) Each Federal agency shall consult with the Administrator in
prescribing standards or regulations respecting noise. If at anv time
the Administrator has reason to believe that a standard or regulation,
or any proposed standard or regulation, of any Federal agency respect-
ing noise does not protect the public health and welfare to the extent
he believes to be required and feasible, he may request such agency to
review and report to him on the advisability of revising such standard
or regulation to provide such protection. Any such request may be
published in the Federal Register and shall be accompanied by a
detailed statement of the information on which it is based. Such acency
shall complete the requested review and report to the Administrator
within such time as the Administrator specifies in the request, but such
time specified may not be less than ninety days from the date the
request was made. The report shall be published in the Federal Reg-
ister and shall be accompanied by a detailed statement of the findings
and conclusions of the agency respecting the revision of its standard
or regulation. With respect to the Federal Aviation Administration,
section 611 of the Federal Aviation Act of 1958 (as amended by section

(c)(l) Any regulation prescribed under subsection (a) or (b) of
this section (and any revision thereof) respecting a product shall
include a noise emission standard which shall set limits on noise emis-
sions from such product and shall be a standard which in the Adminis-
trator's judgment, based on criteria published under section 5, is
requisite to protect the public health and welfare, taking into account
the magnitude and conditions of use of such product (alone or in
combination with other noise sources), the degree of noise reduction
achievable through the application of the best available technology,
and the cost of compliance. In establishing such a standard for any
product, the Administrator shall give appropriate consideration to
standards under ocher laws designed to safeguard the health and
welfare of persons, including any standards under the National Traffic
and Motor Vehicle Safety Act'of 19tifi, the Clean Air Act. and the 30 stat. na,
