ABSTRACT
This report presents the development and successful
demonstration of a unique environmental noise monitor-
ing methodology in assessing environmental noise levels
in the Waco, Texas metropolitan area. The methodology
demonstrated utilizes the least sophisticated of
sound measuring equipment, namely, the hand-held
sound level meter, cassette recorder, stopwatch,
an inexpensive tripod, and an inexpensive weather
station.
Readings from the sound level meter were made
every 10 seconds by students and other personnel in-
experienced in noise measurements, who had received
only a minimal amount of training, and recorded on data
sheets specifically designed for this project. The
cassette tape recorder was turned on at five-minute
intervals for approximately twenty seconds. Weather
data was also collected during each hour of monitor-
ing, and the calibration of the sound level meter
was checked before and after each hour of monitoring.
Data obtained was compared to data obtained using
the more sophisticated tape recorder and noise
classifiers. The results of the comparisons proved
-------
that the methodology used is sufficient for the pur-
pose of community noise surveys to assist local plan-
ners, and that untrained personnel using the least
expensive of equipment can successfully make the
necessary sound level measurements.
Environmental noise measurements were made at
seventeen sites. In selecting sites, consideration
was given to noise sensitivity of land use, proximity
to known or potential environmental noise sources and
discreetness of land use area.
From the data obtained In this assessment, It
can be concluded that the environmental noise levels
in the Waco, Texas, metropolitan area are In a range
that are not, for the most part, considered annoying
or intrusive. Waco, Texas, Is a marginally quiet
city and it is recommended that steps be taken by
the city government to assure that it will remain
quiet. These steps include the adoption of a noise
ordinance and the establishment of a noise unit of
city government.
This report was funde.d by the Office of Noise
Abatement and Control of the U.S, Environmental Pro-
tection Agency.

I CONCLUSIONS
The results of an extensive environmental noise
assessment conducted in the Waco area November 29,
1973 through December 3, 1973 and January 8-11, 1974
are contained in this report.
The following conclusions can be made as a result
of this activity:
1. The principal noise sources in the Waco
Metropolitan Area are rail and motor carriers, auto-
mobile and motorcycle traffic, and barking of dogs.
2. Secondary noise sources include aircraft,
namely, the military helicopters and private propeller-
driven aircraft, home power tools, factories, and both
light and heavy construction.
3. A comparison of the noise level statistics
derived from noise measurements in the Waco Metropolitan
Area with levels identified by the EPA and other Fed-
eral agencies leads to the conclusion that it is a
marginally quiet area on the whole and should be pro-
tected from future major noise sources.
4. An environmental noise assessment of a metro-
politan area can be conducted utilizing the least
expensive of the available noise measuring equipment,
-------
manned by inexperienced personnel after receiving only
a minimal amount of training.
5. Twenty-one Baylor University students have been
oriented and trained to make noise measurements using a
type 2 hand-held noise level meter and could compose a
cadre of local personnel for conducting future noise
assessments in the Waco area.
6. Personnel from other Region VI Environmental
Protection Agency Programs, namely, Management Division,
the Pesticides Branch and the Oil and Hazardous Sub-
stances Branch of the Hazardous Materials Control Divi-
sion have been properly oriented and trained for use
in future environmental noise assessments in noise
critical areas in Region VI.
7. The Region VI, Environmental Protection Agency
Noise Program has obtained additional noise measuring
equipment, has developed a computerized data reduction
system, and is better prepared to conduct environmental
noise assessments and surveys.
8. The Waco, Texas noise awareness program has
been further implemented and considerably more interest
has been generated as a result of six lectures and
demonstrations that were conducted to various high
school science classes and other interested parties,
and also as a result of extensive local participation
in the project.
-------
9. Environmental noise data were obtained at
seventeen sites in the Waco metropolitan area over
a four-day period including two week days and two
weekend days. Site-ensemble averages show an aver-
age maximum level of 81 dBA, an average minimum
of 37 dBA and an average LSg of 56+1.8 dBA. Low-
est noise levels were measured in rural and subur-
ban areas with low traffic density. Highest noise
levels were measured at sites located near highways
and interchanges.
10. A spatial study conducted at the Timber-
crest site indicated that there was no statistically
significant difference between A-welghted noise
measurements made at the central station and the
surrounding substations established in the Timber-
crest neighborhood. From the spatial study it can
be concluded that the noise measurements made at
the Timbercrest station are representative of the
entire neighborhood not merely that immediate loca-
tion of the station.
-------
II RECOMMENDATIONS
As a result of the environmental noise assess-
ment conducted in the Waco, Texas Metropolitan Area
the following recommendations are respectfully sub-
mitted.
1. The City of Waco, Texas either establish
a noise unit of city government or delegate all
noise responsibilities to an existing city unit.
2. An evaluation be made of the existing city
nuisance ordinance; determine its utility in light
of the new Federal legislation and consider adopting
a new comprehensive noise control program including
an effective noise ordinance and proper land use
planning.
3. Noise measuring equipment be purchased by
the City of Waco.
4. The City of Waco assume the lead role in
initiating a follow-up phase of this project, by re-
peating the assessment in April or early May, 1974
to determine the impact of moving commercial airline
training flights to James Connally Airport.
5. The City of Waco utilize the trained cadre
of Baylor Physics Department students and consider
-------
training and utilizing high school students to assist
in making noise measurements at the same sites used
in this survey.
-------
Ill INTRODUCTION
The Environmental Protection Agency's noise control
activities are authorized by the "Noise Pollution and
Abatement Act of 1970"(Title IV of the Clean Air Act),
and the "Noise Control Act of 1972". The broad mission
of the new EPA Office of Noise Abatement and Control,
established in April 1971, is to identify and classify
causes and sources of noise and determine their effects
on public health and welfare. The enabling legislation
requires that a special report to Congress be prepared
which will include information on present Federal pro-
grams, State and local laws, regulations, and enforce-
ment capabilities. This report will also contain the
state-of-the-art on control technology and recommenda-
tions on a long-range National noise abatement and
control program. The law also requires that, for the
first time, all Federal agencies include noise as a
consideration in preparing statements describing the
environmental impacts of their various projects.
The law further directs the Environmental Pro-
tection Agency to develop criteria with respect to
noise, to publish information on the levels of environ-
mental noise required to protect public health and
welfare, and to identify major sources of noise. The
-------
Environmental Protection Agency is also directed to propose
noise emission standards for identified major sources of
noise.
In support of the national mission, the Region VI
Environmental Protection Agency noise program developed
and implemented a program to conduct an environmental
noise assessment in the Waco, Texas metropolitan area.
The Waco, Texas metropolitan area was selected for
this project for a number of reasons; namely, interest
expressed by the City officials to obtain environmental
noise data for use in land planning and zoning; the
availability of students in the Baylor University Physics
Department to assist in manning the monitoring stations,
and the availability and interest of competent faculty
members to provide the leadership necessary to complete
this type of activity; the availability of well organized
environmental high school organizations to assist in the
monitoring; the size of the metropolitan area and the
availability of discrete noise sensitive land use areas;
and lastly, the project provided an opportunity to obtain
base-line noise data at stations located in close proximity
to the Texas State Technical Insitute located at the
-------
site of the deactivated James Connally Airport where
commercial aircraft training flights began shortly
after the official opening of the new Dallas-Fort
Worth Airport.

IV DESCRIPTION OF THE WACO, TEXAS METROPOLITAN AREA
The City of Waco, Texas, is located near the
geographical center of Texas and almost at the center
of Texas' population density (Figure 1). Waco is
approximately 100 miles south of Dallas, Texas. The
area of the City is 76.61 square miles and is en-
compassed by level plains suitable for farm and pas-
ture land, Waco is approximately 427 feet above mean
sea level. The mean annual temperature is 67.2 de-
grees F, and Waco has an average annual rainfall of
32.08 inches. Average relative humidity (yearly aver-
age) is 80% at 6:00a.m. and 54% at 6:00p.m.
The present population of the City of Waco is
over 102,000 persons and the Waco metropolitan area
population is over 150,000 persons. A map of the
Waco, Texas, metropolitan area is shown on Figure 2.

V PROJECT OBJECTIVES
The objectives of this project were:
1. To measure environmental noise levels in noise
sensitive land use areas in a metropolitan area of approxi'
mately 150,000 persons for the purpose of:
a. Obtaining an environmental noise assessment
of the area for use in land planning, zoning and future
development of the metropolitan area;
b. Determining the impact of commercial and
private aircraft servicing the area and the impact of
surface transportation and construction noise sources;
c. Obtaining baseline environmental noise data
in the vicinity of the Texas State Technical Institute
located at the site of the deactivated James Connally
Airport for use in determining the impact of moving
major training activities from the Greater Southwest
Airport in Fort Worth, Texas to the James Connally Air-
port in Waco, Texas.
2. To orient and train local personnel in noise
measurement methodology and techniques.
3. To orient and train Region VI Environmental
Protection Agency personnel in noise measurement
methodology and techniques for the purpose of future
noise assessments in noise sensitive areas in Region VI.
12
-------
4. To evaluate a noise measurement methodology
developed by Region VI Environmental Protection Agency
Noise Program personnel whereby the least expensive
equipment could be manned by interested persons
after only a minimal amount of training.
5. To further implement the Waco, Texas noise
awareness program through lectures and noise measur-
ing demonstrations to high school science classes
and other interested local representatives.

-------
VI DESIGN OF MONITORING PROGRAM
Sampling sites were chosen for a variety of
reasons ; however, most of the sites represent noise
sensitive land uses. An effort was also made to
choose residential and school sampling sites that
are representative of other residential and school
areas in the city.
The sites at Elm Mott, Texas State Technical
Institute, and Timbercrest were also selected on
the basis of their proximity to the James Connally
Airport where commercial air-carriers were to begin
training operations after the opening of the new
Dallas-Fort Worth Airport.
Some areas, such as those surrounding McLennan
Community College and Robinson, are projected to ex-
perience rapid increases in population density.
Data from these sites will assist city planners in
developing land uses congruous with existing noise
levels. Also, the site near Waco Municipal Airport
was selected at the request of Waco city officials
because this residential area is being considered
for annexation to the city.
Enough sites, 17 in all, were used for data
14
-------
collection to obtain a broad picture of the noise
environment of the Waco metropolitan area (Figure 2).
Fundamental to this study is the assumption that each
sampling site is representative of a homogenous area,
and that the data collected at the particular sampling
site would be similar to data obtained at other points
within that homogenous area if they were used for
sampling. To test this assumption, a spatial study
of the Timbercrest site was initiated. In the spatial
study, data was collected simultaneously at four
locations at radius of 1/2 mile from the regular
Timbercrest site, where data was also being collected.
Then, the four peripheral stations were moved to
locations at a 1/4 mile radius from the central
Timbercrest site, and data was again collected simu-
ltaneously at all five stations.
The schedule for data collection was designed
to provide information for both weekend and normal
work days. Both day and night data was collected on
an hourly basis in order to observe changes in the
noise levels as a function of time. Analog magnetic
tape recordings were made for the purpose of identify-
ing noise sources. By knowing both the hourly noise
15
-------
levels and the major contributing sources of noise,
it would be possible to develop effective controls
for noise-generating activities that proved to be a
problem. For example, this information would be of
the type needed for the city to adopt curfews as part
of a new noise control code.
In as many instances as possible within the
limitations of manpower and availability of equipment,
enough data was collected to obtain the A-weighted
Day-Night Average Noise Level. This was done in
order to comply with the recommendations for measure-
ment of community noise levels as suggested by the
EPA document Public Health and Welfare Criteria for
Noise published July 27, 1973.
One of the major objectives of this project was
to develop a monitoring methodology within the means
of a community of moderate size. To this end, a
sample "hand-held" meter station was developed, at
which data would be recorded manually. However, to
provide a validation of the data obtained by the
hand-held meter stations, each site was visited by
at least one of two roving stations. These roving
stations consisted of a vehicle equipped with precision
16
-------
magnetic tape recording systems and environmental
noise classifiers. The tape recordings obtained
from the two roving stations also provide a means
of identifying the major noise sources, can be exam-
ined for the presence of short duration noises which
might not be evident from the sampling type of data,
and can be used for more thorough analysis than of
amplitudes alone, should such scrutiny be necessary
for important sources.

VII DEVELOPMENT OF MONITORING METHODOLOGY
A major objective of this project was to develop
and evaluate a noise measurement methodology that
utilizes the least expensive of equipment and requires
a minimal amount of training for implementation. The
noise measurement methodology developed and refined
during the course of this project is sufficient for
purposes of community noise surveys to assist local
governments in city planning and development of noise
codes. The equipment is low enough in cost that most
cities can afford several stations; and it is simple
enough to be operated by high school and college stu-
dents as school projects. Because these noise monitor-
ing stations may be operated by almost anyone, the
noise measurement methodology used for this project
may also serve to stimulate public interest and support
for noise control activities.
A station consisted of a Type-2 "hand-held" sound
level meter that was mounted on a tripod along with a
stopwatch. Each station was also equipped with an
inexpensive cassette magnetic tape recorder, an acousti'
cal calibrator, and a simple weather station. The
station operator was seated in a folding chair and was
19
-------
provided a clipboard for holding the data sheets.
For night operation, a simple bracket held two flash-
lights, one to illuminate the sound level meter and
the other to light the data sheet.
At the beginning of each hour of data collection,
the sound level meter was calibrated, and the condi-
tion of the batteries for the sound level meter were
checked. Then, A-weighted noise levels were recorded
manually on a data sheet at ten-second intervals. At
five-minute intervals, the cassette tape recorder was
turned on for about 20 seconds to provide documentation
of the types of noise sources. After 20 minutes of
data collection, the station operator interrupted the
noise data collection to record the weather conditions.
A sling psychrometer was used to determine the tempera-
ture and relative humidity. The speed and direction
of the wind were measured and the sky condition was
also noted. After a ten-minute pause, the noise
data collection was resumed for another 20 minutes.
The final ten minutes of the hour was spent recalibrat-
ing the sound level meter, and answering a short question-
naire provided at the top of the data sheet. The purpose
of this questionnaire was to identify noise sources and
20
-------
to obtain the station operators'impressions of the
noise conditions. A separate data sheet was used
for each hour of data collection.
To record the noise data, it was originally
intended that the station operator merely place a
mark in a small bin belonging to the row on the data
sheet that corresponded to the observed noise level.
However, a number of station operators began, independ-
ently of one another, to refine this system by identify-
ing sources of loud noises in the bins where only a
single mark was intended. This was done by placing
letters in the bins, each letter corresponding to a
particular type of source. Each of these station
operators also provided a legend for interpreting
his or her own system of lettering somewhere on the
data sheet.
In many instances, these stations were operated
by a single person for as much as twelve hours in
succession. Despite these lengthy shifts, none of
the persons involved expressed extreme difficulty in
carrying out the monitoring. However, the workload
for each member of a two-person team is much more
reasonable.

VIII DISCUSSION
Data Reduction Methods
A total of 442 hourly data sheets were collected
from the hand held stations. All of the pertinent data
from each sheet were transferred to computer coded forms
according to a predetermined format. Then computer
cards were punched from the forms. Included as input
to be stored, manipulated, and printed were site and
date, hour, weather, major and minor noise sources, and
the number of data samples taken at each noise level.
Outputs computed included Lmax, LQ^, L^Q, L^Q, Lgg,
Lgg, Lm-j_n, TNI, Lnp, and LS(_ statistics which were com-
puted for each hour from approximately 230 data samples
of the dBA sound pressure levels taken at 10 second
intervals. Daily statistics were also computed and in-
cluded all of the above plus the L*dn. Besides the
level statistics, correlation coefficients were com-
puted over the hourly statistics LIQ ' L50' an<^ Leq *-°
determine to what degree if any these statistics were
interdependent. A copy of the computer program used
to reduce the hand-held meter station data can be seen
in Appendix G along with sample input and output data
for one site (S-STimbercrest).
27
-------
Data from the environmental noise classifiers were
recorded by hand onto special data sheets for each sam-
pling hour. Like the data from the hand-held meter
stations, these data represented the number of occur-
rences accummulated within amplitude bins of 2 or 3 dB
width. However, the sample rate of the classifiers is
6 samples over a ten second period rather than 1 sample
per ten second period as for the hand"held stations.
Two classifiers operating together provide 24 amplitude
level bins with two overlapping - or 22 individual bins
with sample counters. These data were transferred to
coded forms and then to punched cards and reduced by
digital computer. The computer program for the classi-
fier data reduction can be seen in Appendix H along with
sample input and output. Like the hand-held meter data,
statistics were computed for each hour. Daily statis-
tics were not computed since the classifiers did not
stay at any one location more than two hours.
Analog magnetic tape data were stored for later
playback analysis. This type of data is highly desirable
since there are a number of different types of analy-
ses which can be performed with it. In this study the
28
-------
tapes were played back through the classifiers on
A-weighting and the resulting classifier data reduced
by the classifier computer program.
Results of_ Data Reduction
A sampling time schedule for each of the 16 sites
can be seen in Appendix A. The schedule includes
hand-held meter sampling periods and periods during
which the rover stations were taking magnetic tape
data and classifier data.
Statistical noise levels for each site-day can
be seen in Appendix B along with detailed site
descriptions in the form of photographs, maps, and
population statistics.
A comparison of the individual site noise levels
for each day was made with certain criteria levels
which have been identified as significant for their
importance with regard to communication interference
and hearing protection. This comparison can be seen
in Appendix K in which levels and time periods deemed
important by the Federal Highway Administration, U.S.
Department of Transportation, by EPA Office of Noise
29
-------
Abatement and Control, and by the Department of Hous-
ing and Urban Development are displayed. In the ta-
ble, an asterisk has been used to note when a criteria
has been equaled or exceeded by a site noise level
daily average. It should be noted that only one site
did not equal or exceed any of the criteria during
either sampling day. This was S-l Speegleville Park,
a summer recreational area which was desolate during
this period. A rank ordering of the sites in order
of lowest number of exceedances to highest number
of exceedances can be seen in Appendix L. Famililar-
ity with these sites leads one to the conclusion they
are also rank-ordered according to degree of vehicu-
lar traffic, an ordering which was expected.
To compare weekend day noise levels with week
day noise levels, site-ensemble averages for each
day were calculated by combining the daily noise
sample populations of all sites, after normalizing
the data for each site so that each site received
equal emphasis, and calculating LIQ, LSQ, and Leq
for the combination. The results can be seen in
Table 3 in which the L LIO, and Leq appear to
be less for weekend days especially Sunday. However,
the differences are admittedly small. Note that
30
-------
the average for each, day is within + 2.8 dBA of the
EPA identified level of 55 dBA for communication
interference and well below the 75 dBA level identi-
fied for hearing protection.
Throughout the investigation, certain noise
level statistics appeared to be highly correlated
with others. To test this, correlation coefficients
were calculated within 99% confidence limits for
each site among the statistics L]_Q and Leg
These coefficients can be seen in Tables 4 & 5.
Mean coefficients also calculated can be seen. From
these calculations a very high correlation between
LIQ and Lecf emerged and less significant correlations
between Lio~L50/ and Lsg-Leq for most sites. The
exceptions were sites and times where the noise
distributions showed small time fluctuations about
the background level. The correlations for sites
S-l and S-2 are low, due mainly to the lack of
sufficient number of hours of data to compute mean-
ingful coefficients within 99% confidence limits,
and these sites were not included in Table 4.
The results of data reduction of magnetic tape
records and classifier records from the mobile (rover)
31
-------
stations can be seen in Appendixes D and C respect-
ively. A comparison of the noise level statistics
L10 ' L50/ and Leq for tape and classifier stations
at times when both were operating simultaneously
can be seen in Tables 6 and 7 in the form of absolute
differences between the statistics at each site and
time. A total of 28 comparisons yielded mean absolute
differences for the secondary stations of 1.6 dBA
for the L10, 1.3 dBA for the L50, and 2.0 dBA for
the LSq. For th_e primary stations mean absolute
differences were 2.0 dBA for L10, 1.5 dBA for LSQ,
and 1.4 dBA for Lecr Thus, the two methods of meas-
urement are in reasonable agreement.
A comparison of the tape noise level statistics
L10- L50/ and Leq with those derived from the hand-
held meter data can be seen in Table 8 in the form
of differences in the two sets of statistics at each
site and time where sampling times were coincident.
Mean absolute differences of 1.9 dBA for the L-,
1.0 dBA for the L5Q, and 1.7 dBA for the Leq over
a total of 24 sampling periods indicate that within
reasonable statistical and experimental accuracy
that the hand-held meter method is sufficient for
measurement of the statistical noise levels. This
32
-------
assumption is based on the assumed superior precision
and accuracy of the analog magnetic tape method.
Spatial Sampling Study
Four hand-held meter stations were positioned on
the circumference of a circle 1/2 mile in radius with
the center at station S-5, Timbercrest. At the center,
a rover station recorded noise levels on tape during
which the hand meter stations recorded noise levels.
The process was repeated for a circle 1/4 mile in radius
also. Location of these stations can be seen in Appendix I.
The results of the data reduction of the spatial
sampling tests can be seen in Tables 9 and 10. Compari-
sons of the noise level statistics LIQ / L50' an<^ Leq
yielded differences between the individual site value
and the average value of all four circumferential values
plus the central station value. These differences can
be seen in Tables 9 and 10. The mean of the absolute
differences for the noise level statistics are:
L1Q, 2.4 dBA; L50, 1.2 dBA; and Leq, 2.4 dBA for the
outer circle and LIQ, 2.7 dBA; L5o, 0.9 dBA; and
Leg, 2.6 dBA for the inner circle. Thus, the central
station is representative of the area within reason-
able limits of experimental and statistical accuracy.
The Timbercrest site and surrounding area can be con-
sidered to be "spatially homogeneous" with regard to
noise levels within +2.7 dBA.
33
-------
Evaluation of_ Cassette Tape Source Identification Method
During all of the hand-held meter data gathering,
a twenty-second tape recording of the background noise
was taken at five minute intervals. Eight recordings
were made each hour with a twenty minute pause for
weather data gathering and recalibration of instruments.
After the survey was completed, the tapes were
played back and the sources of noise identified for
each site and hour. No attempt was made to establish
noise levels. The list of sources taken from listen-
ing to the cassette tapes was compared to the list
compiled by the data gatherers in the field. Based
on this comparison the following several conclusions
were drawn from twenty hours of tape.
1. A significant number of major sources iden-
tified by data gatherers were not represented on
the cassettes. This is probably due to the recording
sampling period being too short and too infrequent.
Few sources such as sirens were identified from tapes
that data gatherers had not listed.
2. There was too much station operator noise,
such as shuffling of data sheets, talking, and squeaking
of chairs which tended to mask background noise sources.
34
-------
This could be avoided by use of a remote microphone
placed several feet from the station. This would also
improve the omnidirectionality of the microphone.
3. There was too much wind noise caused by use
of built-in microphone without a windscreen. A wind-
screen on a remote microphone would solve this problem.
4. Low level background noise and sources were
almost indistinguishable.
5. Site and time voice identification on tape is
necessary for data sheet correlations.
Based on the above observations, the cassette tape
recordings were not judged to be reliable source identi-
fiers. However.- the method could be greatly improved
by sampling at a higher rate - say once each minute for
six seconds (10:1 time compression) and using an external,
omnidirectional microphone with windscreen. A higher
rate of sampling would require an automatic turning off
and on of the recorder by an intervalometer. This
would increase the complexity of station operation
and the cost per station by about $70.00.
35
-------
Effects of New Noise Sources
As seen in Appendix K, sites S-l, P-3, P-8, S-5,
P-2, P-5, and P-6 all enjoy low noise level exposure
as indicated by the L^n's bein9 just at or less than
the EPA identified level of 55. These sites are also
ones which could experience significant changes in
noise exposure should large commercial jet aircraft
flyovers be initiated in the site areas. S-l, P-3,
and P-8 could suffer from increased commercial air-
line traffic in and out of Waco Municipal Airport
while noise levels at S-5, P-2, P-5, and P-6 could
be affected by nighttime "touch and go" commercial
jetliner practice runs began at Texas State Technical
Institute in January 1974. The extent of the noise
impact depends on the type of aircraft flown, the
flight paths, the flight operations, the number of
flights per day and per night, and atmospheric
conditions. An assessment of this impact should
be made by a followup noise survey at these critical
sites.
36
-------
Noise Reduction in Waco
Control of noise emitted from vehicular traffic
sources would be a significant contribution toward re-
duction of the few areas currently impacted by such
sources. This, plus careful planning and zoning to keep
major sources from impacting residential areas in the
future, could be achieved by a comprehensive noise con-
trol ordinance aimed at source level controls and
proper land use zoning. Further cooperative efforts
between the City of Waco and the Region VI U.S. Environ-
mental Protection Agency could achieve this goal in a
minimum time without disruption of normal business,
recreational, and residential activities. The noise
data gathered during this noise monitoring study can
supply needed background information to support such
an ordinance.

IX GLOSSARY
dB - Decibel — Ten times the logarithm to base ten of
a quantity divided by a reference
quantity.
Lp - Sound Pressure Level Decibel measure of the
mean square sound pressure referenced
to a root mean square sound pressure of
2 x TO'5 nt/m2.
A-Weighting An electrical filter network employed
in sound level meters to cause a meter
to filter out very low and very high
frequency components of sound so that
the instrument response is closely cor-
related with human response to sound.
dBA Sound pressure level measured after
signal has been A weighted.
Type 2 Sound Level Meter A sound level meter which
meets or exceeds the American National
Standards Institute Standard SI.4 - 1971
for Type 2 General Purpose Sound Level
Meters.
LIQ The sound pressure level in dB(A) which
is exceeded ten percent of the time.
46
-------
l-5o ~^ne sound pressure level in dB(A) which
is exceeded fifty percent of the time.
Lg0 The sound pressure level in dB(A) which
is exceeded ninety percent of the time.
L Energy average sound pressure level in
dB(A) over a known sampling period, It
represents a constant sound pressure level
which yields the same overall sound energy
during the sampling period as all of the
sources did which were actually present
and causing a time varying sound level.
It is computed from the following formula:
N Li/l(
Leq - 10 Iog10 / 1 I Sj 10
| N i=i
Z S i
where L.J is the sound pressure level observed
for S-j occurrences or over time S-j . N represents
the number of different discrete levels the
sound pressure level scale is divided into.
N
£ 5. represents the total number of occur-
rences or total sampling time.
47
-------
Ld A day-night weighted twenty-four hour
energy average sound pressure level.
It is computed like the Leq except that a
10 dB is added to levels summed over night-
time period 2200 - 0700 hours. The formula
is :
, in i / i N Ld/in nN Ln + '
Ldn = 10 Iog10 ( 1 z s 10 d/10+lz s.io^T;
D d=l Bn=i '
where Ld is the sound pressure level observed
for Sd occurrences Of the total number D
of day occurrences at all N levels during
the fifteen hour period from 0700 - 2200.
Ln is the sound pressure level observed for
Sn occurrences Of the total number R nf
night occurrences, at all N levels during
the nine hour period from 2200 - 0700.
Lnp Noise Pollution Level - computed from the
formula:
NP = '-so + C-10~'-90) + C-iQ-LgQ)

TNI — Traffic Noise Index - computed from the
formula:
TNI = 4(L10 - L50) + L9Q - 30

INSTRUCTIONS FOR NOISE MONITORING STATIONS
GENERAL DESCRIPTION OF WORKLOAD
One data sheet is to be completed during each hour
of operation. During the first 20 minutes of each
hour, the sound level will be recorded at 10 second
intervals. Also, the tape recorder will be turned
"on" at 5 minute intervals during this first 20
minutes of each hour. The recorder should be on for
approximately 20 seconds at each 5 minute interval.
During the next 10 minutes of a given hour,
weather data will be recorded. Then follows another
20 minute period of noise data taking similar to the
first 20 minute period. The last 10 minutes of the
hour will be used for calibration of the sound level
meter.
PRELIMINARIES
Prior to the first sampling, the sound level
meter must be calibrated. Depress the button marked
"C" . Turn the meter to the "on" position. Depress
the button marked "BAT CHECK" and watch meter needle
to see if it swings past the "BAT" mark on the meter.
Make sure that the button marked "SLOW" is in
the out position. Turn the knob on the side of the
190
-------
instrument until the meter scale reads from 90 to
100 decibels. Place calibrator over the microphone
(with windscreen removed). Start calibrator by
depressing (and then releasing) the button on the
side of the calibrator. Use a small screwdriver to
adjust meter reading to 94 dB. Remove calibrator
and replace windscreen. The calibrator will turn
itself off in about one minute after the button on
its side was last depressed. On the data sheet,
record this calibration level in the blank labeled
"CAL. BEGIN".
At the top of the data sheet, fill in your site
(such as "P-2") , name, day of week, date, and the
time that you will begin taking your data. If the
battery "checked", mark this on the sheet. Make
certain that "SLOW" button on meter is in the out
position. Depress the_"A"_button and mark data sheet
to indicate that you have checked the metet settings.
Also, make certain that the tape recorder is loaded
and that it will run.
TAKING NOISE DATA
First, make a 20 second tape recording and turn
off the machine. Then begin taking sound level readings
191
-------
at ten second intervals by reading the sound level
meter and marking the appropriate box on the data
sheet. The boxes at each noise level are to be
marked in succession. That is, if during the first
hour of data sampling there were 17 readings made
at the 64-66 dBA level, then the first 17 boxes of
the row labeled 64-66 dBA should be marked.
After 5 minutes, start the tape recorder and
continue taking noise level readings. After approxi-
mately 20 seconds turn off the recorder and continue
taking noise level readings for another 5 minutes.
Then turn on the tape recorder for another 20 seconds.
Continue this process until you have taken 20
minutes of noise level data, and have made five 20
second recordings.
During the next 10 minutes, the weather data will
be recorded. Moisten the "wet" bulb of the psychro-
meter with the water provided in the small plastic
bottle. Grasp the metal handle at the end of the
chain and swing the psychrometer in a circle. After
about 2 or 3 minutes, stop swinging the psychrometer.
It is suggested that you "follow through" as you
stop so as not to damage the instrument. Read both
192
-------
the wet and dry bulb temperatures and record the dry
bulb temperature and read the relative humidity
adjacent to the arrow indicator on the slide. Record
the relative humidity on the data sheet.
Also record the wind direction, wind speed and
the time that you took the weather data. The direc-
tions for using the wind speed meter are printed on
the device. A magnetic compass is provided for
reference in determining the wind direction. Give
a brief description of the sky and wind conditions
where indicated on the data sheet. (Example: SKY:
Partly cloudy, WIND: Gusting and variable.)
After 10 minutes have elapsed since the last noise
level reading was made, you will make a 20 second
tape recording and begin taking noise level readings.
Continue for 20 minutes in the same manner as you
did during the first 20 minute period. The last 10
minutes of the hour is to be used to again calibrate
the sound level meter and to answer the questions
at the top of the data sheet. When you place the
calibrator over the microphone and depress the "C"
button and switch to the 90-100 dB scale, and before
you make any adjustment to the meter, start the
193
-------
calibrator and record the meter reading on the data
sheet in the blank labeled "CAL. FINISH". Then
make your calibration. After answering the questions
at the top of the data sheet, prepare a new data
sheet for the next hour.
