Abstract

This report documents a traffic noise data base that was obtained as part of a large research program developed to identify and quantify the

important physical parameters which affect human response to time-varying

traffic noise and to investigate various procedures for rating such noise

so as to enable reliable predictions of subjective response to the noise.

Fifteen-minute recordings of actual traffic noise were made at four microphone positions (7.5, 15, 30, and 60 m from the centerline of the near

lane) at several times of the day at each of seven sites, five representing

nominally constant-speed traffic and two representing stop-and-go intersection traffic. The 107 recordings that resulted were subjected to extensive analysis. The analysis procedures are described and tables and graphs

are included which document, for each recording, the 1/3-octave band spectra

and numerous noise descriptors computed from the time-histories of the Aweighted sound level. As a separate part of this study, recordings also were made of the noise from single-vehicle passbys and from simulated traffic

consisting of controlled drive-bys of up to ten vehicles. These recordings

also were extensively analyzed and the results of these analyses are given.

1. Introduction

The data base documented in this report was obtained as part of a larger

research program [l]i:.' having the following main objectives:

° to identify and quantify important physical parameters which affect

human response to time-varying traffic noise associated with varying

densities of both free-flowing highway traffic and stop-and-go traffic;

° to investigate and compare various measures and computational procedures

for rating time-varying traffic noise and to investigate which method

(or methods) best predicts the subjective response of people to the

noise from various types of traffic situations;

o to develop, if necessary, improved procedures for rating time-varying

traffic noise in terms of measurable parameters of the noise;

° to formulate procedures by which the most useful of the above rating

procedures may be related to other commonly used environmental noise

descriptors

In the course of this study, a number of analog tape recordings were made of the

noise from actual and simulated traffic. These recordings were intended to:

(1) provide a library of stimulus material for use in the

psychoacoustic experiments in this study, and

(2) provide information that will assist in characterizing noise signatures for single-vehicle passbys so as to select appropriate

parameters for use in generating synthesized single-vehicle noise

signatures to be used as stimulus material in one of the psychoacoustic

experiments in this study.

In order to assist in selection of appropriate stimuli for future psychoacoustic

experiments, these tapes were subjected to extensive analyses, including computation of

many different descriptors, or ratings, of the noise recorded on the tapes. This

report documents the results of these analyses, as well as traffic and site

parameters corresponding to each recording. The actual-traffic noise recordings

are discussed in Section 2 and the simulated-traffic noise recordings are described

in Section 3.

— Numbers in square brackets indicate the references in Section 5 of this report.
2. Actual-Traffic Noise Recordings

Analog tape recordings were made of the sound of actual highway traffic,

under either constant-speed or stop-and-go conditions, at various times of day

at each of seven sites.

2.1 Recording System

An array of four microphones was used, each microphone being 1.2 m above the

ground at the microphone location. For measurements along highways, with

constant-speed traffic, the four microphones were located 7.5, 15, 30, and 60 m,

respectively, from the center of the nearest lane and along a line perpendicular

to the highway. For measurements at intersections, the four microphones were

located, at the same distances, along a line bisecting the angle formed by the

two highways. Additional information on microphone locations is given in Appendix A.

Briiel and Kjaer ( B & K) Type 4165 "1/2-inch" back-vented microphone cartridges were used, each fitted with a standard protection grid, a dessicant dehumidifier to

control humidity in the microphone cavity, and a 10-cm diameter polyurethane foam

windscreen.—' Each microphone cartridge was used in conjunction with a B & K Type 2619

from each microphone was transmitted via coaxial cable to a precision sound level

meter (B & K Type 2203, 2209, 2606, or equivalent), used for signal conditioning,

and then to one channel of a instrumentation-grade tape recorder (Nagra Model IV-S

or IV-SJ) which was operated at a tape speed of 38 cm/s (15 in./s).

The dynamic range of each instrument was determined and gain settings were established to obtain the maximum dynamic range of the recording system, so as to

achieve the minimum electrical noise floor and maximum freedom from signal

distortion and clipping. In addition, the overall frequency response for each

channel of the recording system was measured and, where necessary, the tape

recorder settings (bias and equalization) were adjusted to achieve the flattest

frequency response for the particular type of recording tape that was used. After

the completion of a given series of recordings, the performance of the recording

system was again checked in the laboratory.

When the instrumentation was first set up in the field, a "dummy microphone"

(which is not sensitive acoustically and which has an electrical impedance similar to

that of a real microphone) was installed in place of the actual microphone, the

overall voltage level was noted, and a tape recording of the electrical background

noise was made.A'

2/

Commercial instruments and products are identified in this report in order to

specify adequately the experimental procedure. In no case does such identification

imply recommendation or endorsement by the National Bureau of Standards, nor does it

imply that the equipment identified is necessarily the best available for the purpose

This procedure was followed to assist in ascertaining proper functioning of the

instrumentation. The electrical noise thus recorded was always less than the acoustic

background noise.
After each dummy microphone was replaced by an actual microphone, a B & K

Model 4220 pistonphone, which produces an accurately-known sound pressure level,

re 20 yPa, of 124 dB at 250 Hz, was fitted over the microphone and activated. The

voltage gain in the sound level meter was then adjusted until the sound level

meter read the correct level. A 30-s recording was then made of the signal from

the pistonphone.

After these procedures were completed and at the beginning of each subsequent

tape, a 30-s recording was made of the signal produced by a B & K Type 4230 sound

level calibrator, which produces a nominal sound pressure level, re 20 yPa , of 94 dB

at 1000 Hz.ji/ The calibrator signal level, relative to that of the pistonphone, was

read from the sound level meter and noted in the logbook, where the sound level meter

settings for the calibration recordings were also noted.

After at least one calibration tone had been recorded for each microphone

channel, the sound level meter attenuator settings were adjusted to the values

appropriate for the traffic noise to be recorded and the recordings of actual

highway traffic noise were made on the remainder (corresponding to approximately

15 min.) of the tape. During a recording session, channels were sequentially

monitored — acoustically via earphones and visually via recording level meters.

During the audio recordings of real traffic noise, video recordings of all

traffic were made to allow later traffic counts and classification to be made (see

Section 2.3). In addition, Doppler radar measurements were made of vehicle speeds,

in both directions, at the sites where traffic was flowing at a nominally constant

speed (see Section 2.3).

2.2 Site Description

Recordings of traffic noise were made at seven sites, five representing

constant-speed conditions and two representing intersections. All sites were

selected with the following general criteria—' in mind:

" propagation over grass

° essentially level terrain beside highway

° essentially no hills or curves on highway

° no barriers between highway and microphone locations

In selecting the particular sites, these general criteria were interpreted as

^jfoJLlows. There were no hills that would require trucks to downshift or to lose

speed while going uphill. There were no curves that would result in tire squeal

at normal highway speeds and, specifically, no curves of less than 300 m radius. Sites were selected where the ground elevation at the 60-m microphone location was within

plus 3 m or minus 1 m of the highway elevation at the center of the nearest lane and,

further, where a length of highway of at least 300 m was visible from a position 0.6m

above the ground at all four microphone locations.

1/ The Model 4220 pistonphone has tighter level specifications and hence was used,

rather than the Model 4230 calibrator, in setting the gain of each sound level

meter. System calibration at two frequehcies provided some field check of the

frequency response of the system, over a limited, but for traffic noise, critical,

frequency range.

Established by NBS staff, with concurrence by FHWA staff.
The sites representing constant-speed traffic conditions were selected in order

to cover a range of traffic densities (from quite light to near-capacity), a range

of traffic speed limits (A8-88 km/hr) , a range of highway sizes (two- to eight-lane),

and a range of values for the proportion of truck traffic. The sites near

intersections were selected to represent a range of traffic densities and a range of

values for the proportion of truck traffic. The seven sites that were used are described below.

"COMSAT" ~

"195" ~

Constant-Speed Traffic

Recordings were taken on the grounds of the COMSAT Laboratories on

the northeast side of Interstate 270 in Montgomery County,

Maryland. At this location Interstate 270 is a four-lane divided

asphalt concrete highway with a grass median. The speed limit is

88 km/hr and there is relatively little truck traffic.

Recordings were taken along the northwest side of Interstate 95,

between the intersections with Maryland Routes 32 and 175, in

Howard County, Maryland. At this location Interstate 95 is a eight-lane divided cement highway with a grass median. The speed

limit is 88 km/hr and there is considerable truck traffic along

this major highway connecting Washington, n. C, and Baltimore, Md.

"B-W PKOT" ~ Recordings were taken along the southeast side of the

Baltimore-Washington Parkway, midway between the intersections

with Maryland Routes 32 and 198, in Anne Arundel County, Maryland.

At this location the Baltimore-Washington Parkway is a four-lane

divided asphalt concrete highway with a wooded median. The speed

limit is 88 km/hr and no trucks are permitted.

"RT. 28" Recordings were taken on the grounds of the National Geographic

Society on the north side of Maryland Route 28 in Montgomery

County, Maryland. At this location Route 28 is a dual-lane

asphalt concrete road. The speed limit changes from 48 to 64 km/hr near this site and there is relatively little truck

traffic.

"GUDE DR." ~ Recordings were taken along the south side of Gude Driv&, acrosa

from the entrance to the Gude Nursery, approximately 1 mile east

of Maryland Route 355, in Montgomery Country, Maryland. At this

location Gude Drive is a dual-lane asphalt concrete road. The

speed limit is 64 km/hr and there is heavy dump truck traffic

during the daytime.
Intersections

"355 & SHADY GR." — Recordings were taken on the north side of the intersection

of Shady Grove Road and Maryland Route 355 in Montgomery County,

Maryland. At the time the recordings were made Shady Grove Road was a four-lane road and Route 355 was a dual-lane road with extra

turn lanes. Both roads are asphalt concrete. The speed limit on Shady Grove Road is 64 km/hr while that on Route 355 changes from

48 to 64 km/hr near this site. There is moderately heavy truck

traffic. Traffic flow is controlled by a traffic light.

"355 & Q.O. RD." — Recordings were taken on the south side of the intersection

of Quince Orchard Road and Maryland Route 355 in Gaithersburg

(Montgomery County), Maryland. Both roads are four-lane divided

asphalt concrete with extra turn lanes. The speed limit on Quince

Orchard Road is 56 km/hr while that on Route 355 changes from

48 to 56 km/hr near this site. There is light truck traffic.

Traffic flow is controlled by a traffic light.

The descriptions of these sites and of the associated traffic flow are summarized in Table 1. Photographs and plan views indicating roadway geometry and

microphone orientation for each of the seven sites are provided in Appendix A.

2.3 Recording Conditions

All recordings of actual traffic noise were started between the hours of 1300 and

1700 on weekdays during the period 13-2A Jvme 1977. At the times of recording, the

air temperature was between 21 and 29 °C, there was no precipitation, and the road

surfaces were dry. Wind speeds were low, less than 4 m/s, except for occasional

gusts to 6-8 m/s on 17 and 21 June.

The times at which recordings were initiated at the various sites are shown in

Table 2. Also shown in this table, for the five sites where there was essentially

constant-speed traffic, are the average traffic speeds, and the standard deviations

and ranges of these speeds, in each direction during each recording session. For the

two Interstate highways and the Baltimore-Washington Parkway, these statistics are based upon approximately 100 vehicle speed measurements in each direction. '^ For the

lighter traffic flows on RT. 28 and GUDE DR., between 36 and 99 vehicle speeds vjere

measured, in a given direction, during a recording session. No traffic speed

measurements were made at the two sites where there was stop-and-go traffic.

As indicated at the end of Section 2.1, continuous video recordings of traffic

flow were made during each recording session. Each video tape was analyzed, by

visual inspection, to determine the number of automobiles, medium trucks, and heavy

trucks traveling in each direction over the duration of the corresponding traffic noise

recording. These data are presented in Table 3. For purposes of classification, the

three vehicle categories were defined as follows:^

Automobiles - all 2-axle, 4-tire vehicles

Medium trucks - all 2-axle, 6-tire vehicles plus all buses and motorcycles

Heavy trucks - all vehicles with three or more axles

For the two sites at which there was stop-and-go intersection traffic, the

"near-side" data in Table 3 correspond to the sum of traffic flows in the near lanes

of both highways while the"far-side" data are for the far lanes of both highways.

The traffic counts at these two sites are described in more detail in Appendix A.

2.4 Data Analysis System

A block diagram of the data analysis system is shown in Fig. 1. Each tape was

analyzed, one channel at a time, to obtain a graphic plot and digital records of

sound pressure levels versus time.

^ In two cases the number of vehicles measured was 69 and 74, respectively.

In all other cases, more than 83 vehicles were measured.

^ An "automobile" pulling a trailer was classified as an "automobile".

A"bob-tailed "tractor (i.e., a tractor that was not pulling a trailer) was classified as a "medium truck" if it had two axles and as a "heavy truck"

if it had three axles

On these dates, there were occasional wind gusts up to 6-8 m/s; on all other

dates, wind speeds were less than 4 m/s.

'For these runs, no recordings were made with a microphone at 60 m since the

site was heavily wooded beyond about 40 m.

Figure 1. Instrumentation system used in the analysis of the actual-traffic

noise recordings.
To obtain graphic plots of the A-weighted sound level, the electrical signal

from the tape recorder was fed into a precision sound level meter, set for "fast"

A-weighted response, which meets the Type 1 requirements of the American National

Standard Specification for Sound level Meters (ANSI $1.4-1971). The detected

(root-mean-square) output from the sound level meter was input to a B & K Type

2305 graphic level recorder, set for DC response and having a writing speed sufficiently fast to enable the pen to follow closely the signal from the sound level

meter. In this way the effective averaging time of the system was that of the

sound level meter rather than being controlled by the less-well-defined characteristics of the graphic level recorder. A 50 dB logarithmic potentiometer, 50 mm

chart paper, and a writing speed of 1 mm/s were utilized. For each recording

analyzed, the system gain was adjusted to obtain the correct pen position for

the calibration tone that had been placed on the magnetic tape.

To obtain digital records of sound pressure levels, the signal from the tape

recorder also was fed to a General Radio Model 1921 real-time 1/3-octave band

analyzer where the signal was analyzed as A-weighted levels and in one-third octave

bands having center frequencies from 25 Hz to 16 kHz. This analyzer utilizes "true"

integration; i.e., energy-averaged levels over a specified integration time are obtained. For the present analysis the integration time was 0.1 s. Outputs from

the analyzer, in the form of digitally-coded sound pressure levels, were sent on demand (every 0.1 s) to a minicomputer for format and storage on a digital tape

recorder. A remote CRT terminal was used to input calibration data and gain settings

as well as to initiate and terminate the digitizing process. The 1/3-octave band

filters in this analyzer are specified to conform to the Class III (high attenuation)

tolerances of the American National Standard Specification for Octave, Half-Octave,

and Third-Octave Band Filter Sets (SI. 11-1966 (R1971)). The A-weighting filter

response conforms to the Type I requirements of ANSI $1.4-1971.

While the graphic recording and the digital tape were being generated, the

operator monitored the audio recording using a high-fidelity loudspeaker. Whenever

an extraneous noise, e.g., horns blowing or someone shouting, was heard, the

operator activated an event marker which placed a "spike" on the graphic level

record. Activation of the event marker also input, through a summing amplifier,

a 25Hz tone to the real-time analyzer.

The digital tapes were processed on the NBS central computer facility. The

digital tapes were manually edited to remove any questionable runs and some duplicate

runs. The computer was programmed to search for the 25-Hz tone (event marker) and

to delete all data for the previous 5 s (the delay was to allow for operator

reaction time) . The edited digital data were then used to implement analysis to

each analog recording using a number of different noise descriptors.

Since most studies of highway noise have utilized exponentially-averaged, rather

than true mean-square averaged, data, the levels sampled every 0.1 s were exponentially smoothed to obtain data corresponding closely to the levels that would

have been obtained using a precision sound level meter set for fast response. These

exponentially-smoothed data were used for computing all of the descriptors, other

than long-term average sound level, listed in Sections 2.5 and 3.4. Long-term

average sound pressure levels, A-weighted and in 1/3-octave bands, were computed

directly from the 0.1-s average levels obtained from the real-time analyzer.

2.5 Descriptions of Recordings Attained

All of the recordings, corresponding to the dates and times in Tables 2 and 3,

jere analyzed as described below. Note that the background noise due to wind may

lave been higher on 17 and 21 June than on the other dates (see footnote (b) in Table

0.

2.5.1 Frequency Spectra

Using the exponentially-smoothed, digitized 1/3-octave band sound pressure levels (see

the last paragraph of Section 2.4) over the frequency range 50 Hz to 10 kHz, time-averaged

spectra were computed corresponding to the following quantities (see also p. 25):

.1 —

.10 —

LX is the band sound pressure level, re 20 yPa, in decibels,

,5Q — ^ that was exceeded X percent of the time.

.90 ~

.99 —

.EQ — The average band sound pressure level, also known as the equivalent

band sound pressure level, defined as the level, re 20 yPa, in

decibels, of the mean-squared band sound pressure during the stated

time period.

?he spectra were computed for the entire duration (typically 12 to 15 minutes) of

iach recording (excluding those portions that were deleted due to the presence of

extraneous noise such as that due to birds, aircraft, or voices).

Spectra corresponding to each of the above six quantities were compute'd for the

recordings at each of the four microphone locations (7.5, 15, 30 and 60 m) for each

)f the twenty-eight recording sessions listed in Table 2 except at the B-W PKWY

;ite where only three microphones were used (the 60-m microphone was not used due to

:he wooded boundary of the site). Thus, 107 recordings were analyzed for a total of

»42 1/3-octave band spectra. Tabulated values of the six spectra for each recording

?ere generated by the computer. In addition, computer-generated plots of the LI,

.10, L50, and LEQ spectra were produced for each recording„ A copy of each of these

ables^and plots is included in Appendix B» Tables and plots corresponding to the

ecordlng sessions and microphone positions given in Table 4 are included in Tables 5 hrough 8 and FigSo 2 through 5 to illustrate the format and the differences among

he six types of spectra:

The symbols LI, LIO, ... LEQ are used in this report rather than the usual subscripted symbols, L , L , ... L , in order to be consistent with the symbols

in computer-generated tables.

The occurrence of ",0 " in these data tables indicates that the level for that

Such data are omitted from the corresponding plots.

2.5.2 Time Histories and Ratings of A-Weighted Levels

Graphic plots of A-weighted sound pressure level, re 20 yPa, versus time were

produced directly, as described in Section 2.4, for each of the 107 recordings of

actual highway noise. These plots were produced primarily to aid in monitoring

during data reduction. However, for illustrative purposes, the A-weighted sound

level time-history plots corresponding to the data presented in Figs. 2 through 5 are presented in Figs. 6 through 9.

Using the exponentially-smoothed digitized A-weighted sound pressure levels (see

the last paragraph of Section 2.4), computer-generated cumulative probability

distribution plots were produced, corresponding to the entire duration of each of

the recordings.

Each time-history of the exponentially-smoothed A-weighted sound pressure

levels was divided into consecutive 30-s time blocks, plus the remainder of the

record as the final time block. For each time block and also for the entire 12

to 15 minute record, the quantities described in Table 9 were computed and printed

out in the form of a table for each of the recordings.

The quantities TDR and LB require a knowledge of dL/dt, the first

derivative of the A-weighted sound pressure level with respect to time.

Each value of dL/dt was computed from a quadratic equation fitted to the 21

sound levels centered about the time of interest. That is, the previous 10

levels (each corresponding to a 0.1-s duration), the current level, and the

following 10 levels were used in conjunction with a least-squares fitting

routine. This additional smoothing was done in order to avoid values of

dL/dt that were spurious due to statistical scatter and round-off errors. Values of dL/dt based on curve fitting to between 5 and 25 points were

examined for a few cases and it was found that dL/dt was stable in the

range from 15 to 25 points. Co incidentally, smoothing over a 2.1 s interval should produce a time history close to that which "slow" rather

than "fast" exponential averaging would yield.

A copy of each of the following is included in Appendix C for each of

the 107 actual-traffic recordings:

o cumulative probability distribution plots of the A-v/eighted sound

pressure levels observed during each recording

o tables showing the values of LI, LIO, L50, L90, L99, TNI, LEO, SIG, TDR,

LNP, LEOP, and LB for the A-weighted sound pressure levels for each

30-s time block and for the entire duration of each recording.

Examples of these plots and tables, corresponding to the recording sessions and

microphone positions listed in Table 10, are included in Tables 11 through 14 and

Figures 10 through 13 to illustrate the format and tc provide an indication of the

differences among various descriptors.

3. Simulated-Traffic Noise Recordings

A separate field program was undertaken in which vehicles were driven

past a microphone array at controlled speeds and spacings. These

simulated-traffic noise recordings are the topic of the present section.

The recording system described above in Section 2.1 and the data

analysis system described in Section 2.4 were also used for the simulated

traffic studies. The microphones were located as described in Section 2.1.

3.1 Site Description

The recordings of simulated-traffic noise were made at the Fallops

Flight Center facility of the National Aeronautics and Space

Administration. This facility, located near Wallops Island, Virginia,

provided the flat terrain and low background noise (typically, A-weighted

levels from 30 to 35 dB) that were necessary for this work.

A test section was established on Runway 10-28 (bearing 100° and

280°). The microphone array was set up on the grass adjacent to the south

side of Runway 10-28 at a position 440 m from the east end of the runway.

The vehicles ran from west to east along the south side of the runway.

Recordings were initiated at or before the time the first vehicle reached a point 180 m from the microphone array and were continued until the vehicle

was at least 180 m past the array. The centerline of vehicle travel was established as being 7.5 m in from the edge of the asphalt concrete runway.

Photographs illustrating the test section, microphone positioning, and

vehicle orientation are provided in Figs. 14 and 15.

3.2 Simulated-Traffic Conditions

Three traffic speed conditions were selected for inclusion in this

part of the study:

o 88 km/hr constant-speed passby,

o 56 km/hr constant-speed passby,

o "stop and go" in which vehicles approached a simulated traffic light at

56 km/hr, stopped as if at a traffic light, and then proceeded when the

"light" gave a go indication.

Four traffic flow rates were included for the 56 and 88 km/hr constant-speed

passby recordings:

single-vehicle passbys

o multiple-vehicle passbys

A. 300 vehicles per hour (5 per minute)

B. 660 vehicles per hour (11 per minute)

C. 1500 vehicles per hour (25 per minute)

35
Figure 14. Photograph of simulated-traffic showing single-event passby of a truck*

„,<j,, ""•^ '

Figure 15. Photograph of simulated-traffic showing a multiple event,

"stop-and-go" passby.

36
In all cases only a single lane of traffic was established. The highest flow

rate for the multiple-vehicle passbys, 1500 vehicles per hour, is approximately

the maximum flow rate per lane that is likely to be encountered in actual traffic

situations at the speeds used. The lowest flow rate, 300 vehicles per hour-,

corresponds to 1 vehicle every 12 s. It was felt that if audio tapes corresponding

to lower traffic flow rates were desired, they could be made by dubbing together

recordings of individual vehicle passbys.

Prior to the selection of the above vehicle speeds and flow rates,

existing traffic noise prediction models were utilized to establish the

range of values of average A-weighted sound level and of the standard

deviation of the A-weighted sound levels around their median value. These

calculations, v/hich are described in Appendix D, were carried out in order

to establish the desired microphone locations and the desired range of

vehicle spacings. These test parameters were selected so as to enable

audio recordings which would correspond to the range of levels and

variations of interest to the present program. Examination of the data

described below shows that this goal was achieved.

For simulated traffic situations other than single-vehicle passbys, a string of up to ten vehicles was utilized. The basic string consisted of

ten late-model, automatic-transmission automobiles ^;hich were driven past

the microphone array in the order shown in Table 15.

recordings.

The numbers of 4, 6, and 8 cylinder engine types that were included were

based upon the current automobile population in the United States, weighted

somewhat in the direction of smaller cars to account for the probable

future increase in the use of smaller cars due to increased concern over

fuel economy. The order in which the automobiles passed the microphone

array was determined with the aid of a table of random numbers.

Recordings of noise from the additional vehicles listed in Table 16 were made during single-vehicle passbys.

noise recordings.

T4 6x4 loaded dump truck with a vertical diesel

exhaust

B large bus diesel

P "souped-up" pickup truck gasoline

For the constant speed passhys, nine conf ip;urations of "automobiles

and gaps" were used. Gaps were included in order that single passbys of

noisier vehicles could be "dubbed in" to the multiple-event recordings at a later time. In these configurations, 0, 1, 2, or 3 automobiles were

removed from the string of vehicles as sho^im in Table 17.

The drivers of the automobiles maintained the same relative spacing as if a vehicle were not missing from the string. For example, in Configuration 9 for runs with a traffic flow rate of 300 vehicles per hour, Car 3 lagged

Car 2 by 12 s but, since Car 4 was missing. Car 5 lagged Car 3 by 24 s.

39
The desired vehicle spacing was maintained by setting up a number of

markers along the runway, prior to entry into the test section, and

instructing the drivers to stay as far behind the car in front of them as was the separation between markers (or, if one or tv;o cars directly in

front vjere not in a particular configuration, to maintain twice or three

times the marker spacing, respectively). Preliminary trials revealed that

it was difficult for some of the drivers to judge this spacing,

particularly for the longer distances between vehicles. Accordingly, all

drivers were provided with radio receivers and a spotter in the airport

control tower issued verbal instructions to individual drivers so as to achieve the desired vehicle spacing prior to the time when the string of

vehicles entered the test section. By this means, it is believed that

vehicle spacings x-zere maintained to within plus or minus ten percent of the

desired value during each recording session.

A code was established to facilitate labeling of a particular

combination of speed, traffic flow rate, and configuration of automobiles

and gaps as follows:

M - (Speed) (Flow Code)-(Conf iguration)

For constant speed passbys, the speed was designated either 35 or 55 mph

(56 or 88 km/hr); the traffic flow rate was coded A, B, or C, corresponding

to 300, 660, or 1500 vehicles per hour, respectively, and the configuration

was coded in conformance with the above table. ^ Thus M-35B-7A indicates a multiple- vehicle passby, at 56 km/hr, with a vehicle spacing corresponding

to a traffic flow rate of 660 vehicles per hour, and a configuration in

v/hich cars 2, 3, and 7 were not included.

Note that the defined traffic flov7 rate is not changed when 1, 2, or 3 cars are removed from the string. This is because of the intention to "dub

in" recordings of single-vehicle passbys of noisier vehicles (mainly trucks — see below). In this way, it was not necessary to make actual recordings

of constant-speed passbys of strings of automobiles and trucks.

However, for "stop-and-go" tests, in which a string of vehicles

approached, stopped at a simulated intersection, and then proceeded, it was concluded that it would not be possible to dub in single-vehicle passbys,

due to the difficulties in synchronizing speeds for stop-and-go conditions.

Accordingly, mixes of automobiles and trucks were used directly for the

simulation of intersection traffic. Seven combinations of automobiles and

trucks, as shown in Table 18, were used for making the recordings of noise

from simulated intersection traffic.

^ Speed in the configuration code was stated in miles per hour (mph) to avoid

confusion during the tests as only speed in mph was common to all vehicle

speedometers.

intersection traffic.

*Trucks located as in SB Configuration of Table 17,

**Trucks located as in 7B Configuration of Table 17.

As an example of the interpretation of this configuration code, M-INT-35B-8-T3/TA

means that Truck No. 3 replaced the automobile in Position No. A and Truck No. 4 replaced the automobile in Position No. 7. The string of vehicles approached the

"intersection" at a speed of 35 mph (56 km/hr) and the vehicle spacing corresponded

to 660 vehicles per hour. The traffic stopped at the light for 30 s and then

proceeded "as it would in normal driving conditions."

41
i

There were a total of 54 types of runs for "automobiles and gaps" as constant-speed passbys (2 speeds x 3 flow rates x 9 configurations) plus the 7 types

of runs for automobiles and trucks at an intersection. In addition, single-vehicle

passbys were run for each of the 10 automobiles, each of the k trucks, a large bus,

and a "souped-up" pickup truck, for a total of 16 vehicles and thus 48 types of runs; these single-vehicle runs were coded Ij

S - (Speed Code) - (Vehicle Code)

where the vehicle code was INT, 35, and 55 for the stop-and-go, 56-km/hr (35-mph), and

88-km/hr (55-mph) tests, respectively. The vehicle codes were Al through AlO for

the automobiles, Tl through T4 for the trucks, B for the bus and P for the souped-up

pickup truck. Thus, for example, S-35-A7 designated a 56 km/hr passby of the Nova that

occupied Position 7 in the multiple-vehicle passbys.

3.3 Recording Conditions

A least two recordings of each of the 109 types of runs were made during the

period 13-22 July 19 77. At the times of recording there was no precipitation and the

road surfaces were dry. The Wallops Flight Center weather- tower vjas located close to \ the microphone array. Copies of the recorded data for temperature, dew-point

temperature, wind speed, and wind direction were obtained.

Prior to any of the recording sessions, the automobile speedometers were

calibrated and found to be accurate to within +5 km/hr (+3 mph) at both

56 and 88 km/hr (35 and 55 mph). During single-vehicle passbys, drivers were

instructed to maintain the desired speed as closely as possible. During

multiple-vehicle passbys, the lead automobile maintained the desired speed while the

other vehicles maintained the desired separations between vehicles. No radar

measurements of vehicle speed and no video recordings of traffic flow were made

during the simulated-traffic recording sessions.

3.4 Description of Recordings Attained

All of the audio recordings of simulated-traffic noise were digitized and

exponentially smoothed as described in Section 2.4. However, only 2 s of digital

data were deleted prior to each "event marker". The "best" of the duplicate

recordings (see the first sentence of Section 3.3) of each type of run were subjected

to further analysis. "Best" was judged on the basis of acoustical and electrical

background noise, extraneous noises, and wind speed.

Graphic plots of A-weighted sound pressure level, re 20 yPa, versus time were

produced for each of the recordings of simulated-traffic noise. Examples of these

plots, for the multiple-vehicle passbys, are provided in Figs. 16 through 19.

The 1/3-octave band sound pressure levels versus time were digitized as described in Section 2.4.

44
For each recording of a multiple-vehicle passby (4 microphone positions for each

of the 54 constant-speed passbys of "automobiles and gaps" and the 7 runs for

automobiles and trucks at an intersection), the time-history of

exponentially- smoothed digitized A-weighted sound pressure levels was used to generate, for the complete run, the same twelve descriptors that were computed for

the actual-traf f ic recordings.

Copies of the tables showing the values of LI, LIO, L50, L90, L99, TNI, LEQ,

SIG, TDR, LNP, LEQP, and LB for the A-weighted sound pressure levels are included in

Appendix E for each of the 244 simulated-traffic (multiple-vehicle) recordings.

Examples of these tables are included in this report as Tables 19 through 22

corresponding to the plots in Figs. 16 through 19.

Computations of the cumulative probability distribution of A-weighted sound pressure

levels for several of the simulated traffic multiple events were performed. Plots of

these distributions for four of the multiple events are presented in Figs. 20 through

23.

For each recording of a single-vehicle passby (4 microphone positions for each

of the 48 runs), the time-history of exponentially-smoothed digitized A-weighted

sound pressure levels was used to compute each of the following quantities^:

'T L/10 I SEL = 10 log<!// 10 dt> = LEQ + 10 log T; (1)

this is the usual "sound exposure level"

SELF = SEL + 10 log (1+15TDR) = LEQP + 10 log T (2)

where LEQP and TDR are defined in Section 2.5.2; this

quantity may be thought of as a sound exposure level that

has been adjusted, in a manner analogous to that in which

LEQP was adjusted, to "correct" for the influence of the

rate of change of sound level with time

' [l+(15'dL/dt)^] • 10^ dt > = LB + 10 log T , O) If

where LB and L are defined in Section 2.5.2; this quantity

may be thought of as a sound exposure level that has been

adjusted, in a manner analogous to that in which LB i^as adjusted, to "correct" for the influence of the rate of

change of sound level with time

is the root-mean-square value

of dL/dt over the time period T; this quantity was computed

in the same manner as was TDR (see Section 2.5.2) but a different symbol is used to aid in distinquishing between

the quantity computed for single-vehicle passbys and that

for multiple-vehicle passbys

LDD =

(^)

where d^L/dt is the second derivative, with respect to time,

of the A-weighted sound pressure level, L=L(t); LDD may

be regarded as the root-mean-square value of d- L/dt^- over

the time period T.

These quantities were computed with the integration carried out over the entire

duration of the recording and also over only that portion of the recording where the

A-weighted sound pressure level was within 10 dB of its maximum value. In addition,

both LD and LDD were computed, separately, for the time before the maximum level was reached and for the time after the maximimi level was reached.

The quantities LD and LDD require a knowledge, respectively, of dL/dt, the first

derivative of the A-weighted sound pressure level with respect to time, and d^L/dt^,

the second derivative of the level with respect to time. As described in Section

2.5.2, a quadratic equation was fitted to the 21 sound levels centered about the time

of interest. Both dL/dt and d^L/dt were obtained from this quadratic equation for use in computing LD and LDD, respectively. As stated in Section 2.5.2, values of

dL/dt vjere essentially independent of the number of levels to which the Quadratic was fitted when the number of levels was between 15 and 25. However, d^L/dt^ values were

not independent of the time interval over which the smoothing was done; thus values

of LDD may only have significance relative to one another rather than in any absolute

sense.

A copy of the tables showing the values of SEL, SELF, SELB, LD(total), LD(rise),

LD(fall), LDD(total), LDD(rise), and LDD(fall), computed both for the total event and

within the "10-dB down" duration, for each recording is included in Appendix D for

each of the 192 single-vehicle recordings. Examples of these tables are included

here as Tables 23 through 25. The A-weighted sound pressure level time histories

produced on the graphic level recorder, corresponding to the data of Tables 23

through 25, are shown in Figs. 24 through 26. Additional time histories of the

A-weighted levels for the single event recordings are included in Appendix G.

Sound exposure level spectra corresponding to single-vehicle passbys were

computed and are included in Appendix H.

46
Since the entire time history of each multiple-event and single-event

recording is accessible, in digital form, to the NBS central computer, it

is a simple matter to combine, digitally, different sound level time

histories so as to obtain the digitized time history corresponding to dubbing one or more single-event recordings onto a multiple-event

recording. From this synthesized time history, various noise descriptors

of interest can be computed. In this way, it is easy to determine what

values of LIO, LEO, LB, etc. would be obtained if one were actually to dub

together, at a particular relative level, two recordings.

It is relatively easy to predict LEO, TDR, LEQP, and LB for such

dubbed recordings without any need to consider the detailed time histories.

This is discussed further in Appendix I.

4. Discussion of Noise Recordings

In this section some summary information is given on the actual-traffic and

simulated-traffic noise recordings that were obtained in the course of this study,

4.1 Actual-Traffic Noise Recordings

For this summary discussion, it is useful to combine the data for the three

Interstate highway sites, the data for the two secondary road sites, and the data for

the two intersection sites, thus forming three groups of data. The traffic

conditions, given in detail in Tables 2 and 3, are summarized in Table 26 for these

three classifications of sites. For this summary table, all traffic at a given site

was combined, regardless of lane or direction. For all recording sessions at, for

example. Interstate highways, the average traffic speed, regardless of direction,

ranged from 85 to 93 km/hr, with an average value of 90 km/hr. Total traffic volume

at the three Interstate sites ranged from 1990 to 4330 vehicles per hour, with an average value of 302 vehicles per hour, with medium trucks ranging from 1.0 to 7.1

percent and heavy trucks ranging from 0.0 to 15.5 percent of the total traffic

volume. Table 26 provides this type of summary information for the three classes of

Of the twelve descriptors of the A-weighted sound level that are given

in Tables 11-14 and in Appendix C, the following six were selected for further

discussion: LEQ, LIO, LEQP, LB, LNP , and TNI. For the three classifications of

sites, the values obtained for these six descriptors are summarized in Table 27.

For each descriptor, the minimum, arithmetic mean, and maximum values are given

at each of the four microphone positions. Thus, for example, for the eight

recordings at the 15-m microphone for secondary roads ^ the values obtained for LEQ

ranged from 62.0 to 70.7 dB, with a mean of 67.1 dB.

The summary data in Table 27 are shown graphically in Figs. 27-29, where the

minimum, mean, and maximum values for each descriptor are shown versus the distance

from the center of the near lane to the microphone location. (No data are shown for

the 60-m microphone for the Interstate highways since no 60-m microphone position was used at the B-W PKWY site.) Figure 27 shows the mean value and range of LEQ, LEQP,

and LB versus distance. Fig. 28 shows these data for LIO and LNP, and Fig. 2 9 presents the results for TNI. Figure 30 presents the mean values for all six

descriptors on a single plot, with the ranges omitted for graphical clarity.

It can be seen that LIO and LEQ are very similar, with LIO typically being 2 to 4 decibels larger than LEQ. In general, LEQP, LB, and LNP show a slightly more rapid fallofj

with distance than do LEQ and LIO. The range of values for TNI, for a given type of

site and a given microphone position, is much larger than the range for the other

descriptors. In addition, TNI falls off with distance much more rapidly than any of

the other descriptors.

The Federal Highway Administration has recently issued FHI'JA Technical Advisory

T 5040.5, dated September 5, 1978, which describes the FHI-JA Highway Traffic Noise

Prediction Model, and provides "National Reference Energy Mean Emission Levels" as functions of speed for automobiles, medium trucks and heavy trucks. The values of

LEQ that were obtained in the present study have been compared with the values

predicted by the FHWA Highway Traffic Noise Prediction Model for the five sites where

essentially constant-speed traffic conditions existed. In carrying out the

calculations of the predicted values of LEO, it was assumed that each highway was an infinitely-long line source and that the values of LEQ due to a single lane of

traffic fall off at a rate of 4.5 dB per doubling of distance. With these

assumptions, LEQ was computed from (text continued on page 68)

In addition to comparing observed and predicted values of LEQ, a comparison was made of observed and predicted values of SIG, the standard deviation of the

A-weighted sound levels. For this the analysis of Kurze (see Appendix D) was used.

The standard deviations of sound levels, for mixes of automobiles, medium trucks, and

heavy trucks, were calculated from the expression

and the other quantities are as defined above.

In computing LEQ and SIG from the above expressions, it was assumed that all

traffic in a given direction was traveling at the average speeds given in Table 2 and

that the vehicle mixes given in Table 3 were uniformly distributed among the lanes in

a given direction.

The deviations, in decibels, between observed and predicted values of LEQ and

SIG for the 75 recordings corresponding to constant-speed traffic conditions are

listed in Table 28. The first three columns, corresponding to the same columns in

Tables 2 and 3, identify the site, the date, and the time at which recordings were

initiated. The next four columns give, in order, the deviations, observed minus

predicted, for the LEO values for the 7.5, 15, 30, and 60 m microphone positions,

respectively. The last four columns. give the deviations between the observed and

predicted SIG values. For each site, the average (over all recording sessions at

that site) deviations are also given for each microphone position.

In Figures 31 and 32 the average (over all recording sessions at a particular

site) observed values of LEQ are compared with the average predicted values of LEQ

for each of the five sites where there was essentially constant speed traffic. In

these figures, the solid lines represent the predicted values while the data points

correspond to the observed LEQ values. At the COMSAT and 195 sites the average

predicted values are within about +3/-2 dB of the observed values at the three microphone

positions nearest to the highway. At the B-W PKWY site and at the two secondary road

sites, the observed and predicted values are within + 2 dB at the 7. 5 -meter microphone

position but the observed values fall off more rapidly with distance than the

predicted values ; the reason for this phenomenon is not evident.

In Figures 33 and 34 the average observed and predicted values of SIG, the standard

deviation of the A-weighted sound levels, are compared. At all sites and at all

microphone positions, these averages agree to within +1.3/-1.1 dB. At the COMSAT and

RT.28 sites, and the observed values of SIG do not fall off as rapidly with distance

between the 30-meter and 60-meter microphone positions as do the predicted values. At

the 195 site the observed values of SIG are systematically higher than the predicted

values. At the B-W PKWY and GUDE DR. sites, the observed values of SIG tend to fall

off more rapidly with distance than the predicted values, for reasons which are not

known at present.

4.2 Single-Event Noise Recordings

The most-commonly used descriptors of single-vehicle passbys are the

sound exposure level, SEL, and the "10 dB down time", the length of time during

which the sound level is within 10 dB of its maximum value. These descriptors

are tabulated in Tables 29-31 for the sixteen vehicles for which single-vehicle

passby recordings were made. Table 29 corresponds to the 88 km/hr (55 mph) passbys.

Table 30 to the 56 km/hr (35 mph) passbys, and Table 31 to the stop-and-go passbys.

In these tables, the data for the five Nova, two Maverick and three Chevette

automobiles have been grouped together, and arithmetically averaged values of SEL

and the 10 dB down time are shown for each model of automobile. In addition, the

averages over all ten automobiles are shown. The averages over the four trucks are given also.

In Fig. 35 the average A-weighted sound exposure levels are shown versus distance for automobiles and for trucks. The "error bars" for the trucks show

the range of SEL values for the four trucks. The error bars for the automobiles

show the range of the averages for the three models of automobiles (not the

range for the ten individual vehicles) . For all three types of passbys, the

average values of SEL decreased, on the average, by about 6 decibels per

doubling of distance.

Figure 36 shows the average values and the ranges of the 10 dB down times

for automobiles and for trucks. The symbols otherwise have the same meaning

as in Fig. 35. For the constant-speed passbys, the 10 dB down times roughly

doubled in going from the 7.5 meter microphone position to the 30-meter

position.

levels produced by the vehicles did not mu ch exc eed the

Appendix A.

Description of Sites for Actual-Highway Noise Recordings.

Information concerning each of the seven measurement sites used

for the traffic noise tape recordings discussed in Section 2 is

presented in this appendix. For each of the sites, a photograph

(taken from a position near that of the 60-m microphone) showing

a segment of the roadway at the site and several of the microphone

positions used for the recordings at that site is included. Also,

plan view drawings of each site, indicating the dimensions of the

roadway in the vicinity of the site and the orientation of the

microphone array to the roadway, are presented in this appendix.

Traffic speeds, flow rate, and mixes for each site are given in Tables

2 and 3 in the main body of this report. For the two sites where

there was an intersection, additional details are given in this

appendix concerning the traffic counts.

Appendix B.

Spectra from the Actual-Traffic Recordings

This appendix includes tables of the 1/3-octave band spectra corresponding to LEQ, LI, LIO, L50, L90, and L99, for all 107 actualtraffic recordings. The 1/3-octave band sound pressure levels are relative to a reference sound pressure of 20yPa and are expressed in

decxbels for the 1/3-octave bands having center frequencies from

50 to 10,000 Hz. The data recording and analysis procedures are described in Sections 2.3 and 2.4, respectively, of the main body

of the report. Representative data are presented in Section 2.5.1.

Wherever a level was at or below the baseline level of the real-time

analyzers, during the analysis of that recording, it was replaced

by the value of zero. In addition, plots of the data are included for

the LEQ, LI, LIO, and L50 spectra. The spectral tables and plots are

in the order given below:

Appendix C.

Descriptions of the A-Weighted Sound Levels for the Actual-Traffic Recordings

This appendix includes, for all 107 actual-traffic recordings, (1) plots of

the cumulative probability distributions of the A-weighted levels and (2) tables of

the various descriptors of the A-weighted levels. The probability distributions

(1 to 99 percent) correspond to the entire duration of each recording. The tabulated descriptors are given for each 30-s time block (the last time block is the left-over time in excess of an integral multiple of 30 s) throughout the duration

of each recording and also for the entire duration of each recording. The data recording and analysis procedures are described in Sections 2.3 and 2.4, respectively,

of the main body of this report. Representative data are presented in 2.5.2. The

plots and tables are in the order given below:

Appendix D.

Selection of Traffic Flow Densities and Microphone Locations

for Simulated-Traffic Noise Recordings

In this appendix, calculations are described that were used as an aid in

selecting traffic flow densities and microphone locations for the simulatedtraffic noise recordings. A goal in making these selections was to ensure that

a library of recordings was obtained which covered both a large range of sound

levels and of variation of sound levels, within the ranges of interest for use

in the proposed psychoacoustic experiments.

Because of the existence of suitable predictive models, the average (on a mean- square-pressure basis) sound level, LEQ, and the standard deviation of the sound

levels, SIG, were selected as the noise descriptors for use in these calculations.

The predictive models, described below, are based upon data obtained for

''average" traffic in the United States. It was realized that the small number

of vehicles to be used in this study might not conform, in terms of noise emission, to average U.S. traffic. Furthermore, the predictive model used for calculation of SIG values is based upon certain assumptions, such as statistical

independence among different variables, that are not met by the structured con- ditions used for the simulated-traffic noise recordings. Nonetheless, it was believed that the predictive models would be useful in estimating the ranges in

LEQ and SIG that might be expected for the simulated-traffic noise recordings.

D.l. Average Sound Levels

The average (on a mean-square pressure basis) sound level, LEQ, for free-flowing

traffic on an infinitely-long highway was computed by summing up the contributions

from three classes of traffic:

LEQ = 10 log

i=l

(D.l)

in this equation i = 1, 2, or 3 for automobiles, medium trucks, or heavy trucks,

respectively. For each class of traffic, the average sound level was computed

from an equation supplied by the Federal Highway Administration [Dl]. Converted

to the International System of Units, this equation can be written in the form:

f .VD D LEO.XI= L. +0.115a2 + IQ log ^^ ° + 15 log-^ - 26.18, (D.2)

1 ° S D

where

L. = average source level (dB) for the i-th class of vehicles when traveling

at speed S;

a. = standard deviation of source levels (dB) for the i-th class of vehicles

when traveling at speed S;

D-1
V = total traffic flow rate (vehicles/hr) for all three classes of vehicles

combined;

f. = fraction of the traffic flow that is in the i-th class; thus f•, V is the

number of automobiles per hour; also, f + f + f = 1;

S = traffic speed (km/hr)

;

D = reference distance (m) at which source level is measured;

oD = distance (m) from center of defined traffic lane.

The Federal Highway Administration also supplied the following equations

for computing L-^, the average source level, and a^, the standard deviation of the source levels, for the three classes of vehicle [ D1 ] :

Automobiles

L^ = -3.1 + 38.05 log S,

In these equations, D = 15m and S is expressed in km/hr.

The upper drawing in Fig. Dl shows a , plotted versus vehicle speed, for

the three classes of vehicle, as computed from Eqs. (D.4), (D.6), and (D.8).

The solid curves in the lower drawing in Fig. Dl correspond to the values of L-^ computed from Eqs. (D.3), (D.5), and D.7). The dashed curves in the lower drawing correspond to the term, L. 4- 0.115aj_, from Eq. (D.2).

D.2. Standard Deviations of Sound Levels

The standard deviations of sound levels, for mixes of automobiles, medium

trucks, and heavy trucks, were calculated, following the analysis of Kurze[D2, D3]

,

from the expression

SIG * 4.34/ln(l+K2), (D.9)

where k^^ is the second-order cumulant (or semi-invariant) of the sound intensity

normalized with its mean value. The cumulant itself was computed from

where V, f^, S, and D are as defined above in Section D.l. The factor of 1000

derives from the fact that S is expressed in kilometers per hour but D is ex- pressed in meters.

D.3. Calculations Performed Prior to Selection

of Simulated-Traffic Parameters

Given the Lj^ and o^ values from Eqs. (D.3) through (D.8), the predicted

values of LEQ and SIG are functions only of V, f^, S, and D.

It was decided that there would be little point in selecting more than two

values of S for the simulated-traffic noise recordings, since neither LEQ nor

SIG change rapidly as S is changed over the speed range of interest. The values

S = 56 and 88 km/hr (35 and 55 mph) were chosen as representative of the most

commonly-encountered speeds for steady traffic flows.

Since only ten vehicles were to be used in the multiple-vehicle simulatedtraffic studies, the fraction of medium or heavy trucks could not be changed

continuously but rather only in steps of 0.1 or, if two recordings were combined, in steps of 0.05.

Based upon the above, it was decided to fix S at 56 or 88 km/hr, vary f.^ and fo incrementally in 0.05 steps, and to explore the influence of V and D, as continuous variables, on LEQ and SIG. After exploring alternative ways to

present the results, it was decided to plot equal-LEQ and equal-SIG contours on

the same drawing with D as the ordinate variable, V as the abscissa variable.

and S, f. and f, fixed.

Figure D3 is an example of such a plot, with S = 88 km/hr and f2 = f3 = (i.e., 100 percent automobiles). The solid lines represent LEQ-contours of 40,

50, 60, and 70 dB. The dashed lines represent SIG-contours of 3, 6, and 9 dB.

Figure D4 is another example, still with S = 88 km/hr but with f3 = 0.15 (i.e.,

85 percent automobiles and 15 percent heavy trucks). The inclusion of the heavy

trucks shifted the LEQ contours by about 8 dB and significantly increased the value

of SIG corresponding to a given value of V'D.

A large number of tables, containing information equivalent to that represented by Figs. D3 and D4 , were generated for different values of S, f ;^ , f 2 , and

fj. These tables were studied to ascertain the ranges of LEQ and SIG values

that would be expected, for different ranges of V and D, for different values

of S, f^, f2, and fg. In addition, the following practical considerations were

taken into account:

1, With traffic flow rates greater than 300 vehicles per hour, the noise

exposure for persons located outdoors at distances significantly closer

than 7.5 m from a highway would be excessively high regardless of what

D-6
noise descriptors were used. Furthermore, based upon conversations

with Federal Highway Administration officials, it was assumed that very

few highways of conceini to the FHWA would have people living closer

than 7.5 m from the center of the nearest traffic lane.

2. It would not be practical to utilize microphone locations further than

60 m from the center of the traffic lane. This conclusion was based

chiefly upon considerations of background noise and wind-generated

noise at the microphone.

3. It would not be necessary to make recordings of multiple-vehicle passbys at traffic flow densities less than about 300 vehicles per hour.

This decision was made, not because such situations were not of interest^

but, rather, because with one vehicle passby every 12 s, or less frequently, it would be easy to combine single-event recordings to achieve

any desired multiple-event situation.

4. It would not be necessary to make recordings of multiple-vehicle passbys at traffic flow densities greater than 1500 vehicles per hour since

1500 vehicles per hour per lane is a practical upper limit for traffic

flow densities on real highways.

Based on all of the above considerations, it was decided to use microphone

positions located 7.5, 15, 30, and 60 m (nominally 25, 50, 100 and 200 ft) from

the centerline of vehicle travel. Traffic flow rates of 300, 660, and 1500

vehicles per hour (5, 11, and 25 vehicles per minute) were selected, based upon

300 and 1500 vehicles per hour as the lower and upper limits, respectively, with

660 chosen as (approximately) the geometric mean of 300 and 1500.

D.4. Agreement between Predicted and

Observed Values of LEQ and SIG

It was known, a priori, that the predictions of LEQ and SIG would only

agree approximately with observed values obtained from the simulated-traffic

noise recordings since the vehicles used would not produce noise emissions

corresponding to the average values assumed in the models and since the models

were known to be only approximately correct for the test conditions used. However, the predictions served their purpose by providing information useful to the selection of the ranges of D and V. Nonetheless, it is of some interest

to examine how well the predicted values did agree with those that were actually

observed. Table D.l shows such a comparison for the 56-km/hr tests with ten

automobiles and no gaps. Table D.2 shows the same comparison for the 88-km/hr

tests with ten automobiles and no gaps.

Multiple-vehicle, constant-speed passbys with trucks included were not ac- tually made. Rather, as described in Section 3, recordings were made with

"automobiles and gaps," the intent being to dub single-event recordings into the

gaps. Thus, it is more difficult to compare the predicted and observed values

for mixes of automobiles and trucks. However, as described in Appendic G, two

"cars-and-trucks" recordings were synthesized, on the computer, and the values

of the corresponding noise descriptors were computed. In Table D, 3 these com- puted values of LEQ and SIG are compared with the values predicted using the

equations from Sections D.l and D.2.

Inspection of the entries in Tables D.l to D.3 reveals that the predictions

of LEQ and SIG were not in particularly good agreement with the observed values.

Additional analysis, and perhaps additional data, would be needed in order to

make more quantitative statements about the validity of these predictive models.

However, as discussed in Section 4, similar predictions were in rather good

agreement with data obtained for actual-highway traffic noise.

Appendix E.

Descriptors of the A-Weighted Sound Levels for the Simulated-Traffic

Multiple-Vehicle Recordings

This appendix includes the several descriptors for each of the simulatedtraffic multiple-vehicle recordings described in Section 3.2. The data recording and analysis procedures are described in Sections 2.4, 3.3, and 3.4 of the

main body of this report. The format of the tables is the same as that of

Tables 19 to 22 in the main body of the report„ The identification code for

individual runs is described on pages 40-41.

The group of 88-km/hr (55-mph) passbys is first, followed by the 56-km/hr

(35-mph) passbys and then by the stop-and-go (intersection) passbys. Within

each group, the 300-vehicle-per-hour subgroup (A) is first, followed by the

660-vehicle-per-hour subgroup (B) and then by the 1500-vehicle-per-hour subgroup (C)o For the constant-speed passbys, the configuration order in each

subgroup is:

Appendix F

Descriptors of the A-Weighted Sound Levels for the Simulated-Traffic

Single-Vehicle Recordings

This appendix includes the several descriptors for each of the simulatedtraffic single-vehicle recordings described in Section 3.2. The data recording

and analysis' procedures are described in Sections 2.4, 3.3, and 3. A of the main

body of this report. The format of the tables is the same as that of Tables

23-25 in the main body of the report. The identification code for individual

runs is described on page 42.

The group of 88-km/hr (55-mph) passbys is first, followed by the 56-km/hr

(35-mph) passbys and then by the stop-and-go (intersection) passbys. Within

each group, the ten automobiles (Al, A2,...A10) come first, followed by the

four trucks (Tl, T2, T3, T4) , the bus (B) , and, finally, the souped-up pickup

truck (P) . The overall order is as follows:

Vehicle Speed ConditiotiI Identification

Appendix G.

Time Histories of die A-Weighted Levels for

the Simulated-Traffic Single-Vehicle Passbys

Graphic level recordings ("fast" response) of the time histories of the

A-weighted sound levels for the single-vehicle passbys are included in this appendix.

In the present study, the major interest with regard to these time histories is

the shape of the curves rather than the actual levels obtained. Thus ordinate

scales have not been placed on each curve. Rather, only the sound level range

(50 dB) of these plots is shown. A time scale is shown for the abscissa. For

the 56-km/hr passbys, a recording of nominally 22 sec is shown. For the 88-km/hr

passbys, a 15-sec recording is shown. For the stop-and-go passbys, a record

length of 60 sec is displayed. Figures Gl through G24 display these time

histories, organized as follows:

In each of Figures G1-G12, ten plots are shown corresponding to the ten automobiles

(see p. 38) which were used. In each of Figures G13-G24, six plots are shown,

corresponding to the four trucks (see Table 16, p. 38), the bus, and the souped-up

pickup truck.

Appendix H.

Sound Exposure Level Spectra for the Simulated-Traffic

Single-Vehicle Passbys

Sound exposure level spectra for the single vehicle passbys are included in

this appendix. In the present study, the major interest is in the shape of these

spectra, rather than in the actual levels obtained. Accordingly, all sound exposure

level spectra are presented as levels relative to the corresponding A-weighted

single event level. Tables HI through H24 list these normalized spectra, organized

as follows

Automobiles:

Speed condition Microphone position

7.5 m 15 m 30 m 60 m

56 km/hr Table HI Table H2 Table H3 Table H4

88 km/hr Table H5 Table H6 Table H7 Table H8

"stop and go" Table H21 Table H22 Table H23 Table H24

In each of Tables HI through H12, the normalized 1/3-octave band sound exposure levels

are listed versus frequency from 50 to 10,000 Hz for the ten automobiles (see Table 15

on page 37) which were used. In addition, the arithmetic mean level and the standard

deviation of the levels (for the ten automobiles) are listed for each 1/3-octave band.

These mean levels, and the plus or minus one standard deviation limits, are plotted in

Figures HI through H12. In each of Tables H13 through H24, similar normalized levels

are given for the four trucks (see Table 16 on P. 38), the bus, and the souped-up

pickup truck. The means and standard deviations are given, for this rather inhomogeneous set of vehicles, in the tables and corresponding figures.

Prediction of Noise Descriptors for Dubbed Tapes

Since LEQ represents an "energy average" of mean-square sound pressure over

the time interval of interest, it is easy to predict the effect, on LEQ, of

dubbing single-event recordings into a recording of automobiles and gaps. If

the original recording is of duration T and its average sound level is LEQ, the

average sound level of the dubbed recording should be:

LEQ* = 10 log ,0LEQ/10 ^ E10 (SELi - 10 log T)/10 (I.l)

where the i-th single event recording has a sound exposure level of SEL..

Under conditions described below, it also is straightforward to predict LB

for a dubbed recording. For each recording of automobiles and gaps, both L and

dL/dt were sufficiently low during the "gap" portions of the recording so that

these portions did not contribute significantly to LB. If a single-event re- cording is dubbed into such a gap and if the duration of the single event (e.g.,

as defined by the "10 dB down time") is shorter than the duration of the gap

(e.g., the time when the sound level is at least 10 dB less than the maximum

levels due to the automobiles) , then there is little interaction between the

recordings (i.e., L and dL/dt each may take on significantly large values, at

any given time, due to the contribution from one recording or the other but not

both) and the rating, designated LB*, for the dubbed recording is approximated by:

LB* ^ 10 lo? -^qLB/10

_^ y^ ]^Q(SELBi - 10 log T)/10

(1.2)

Similarly, when there is a little "interaction" between the multiple-event

recording and the single-event recordings, the root-mean-square value of the

rate of change of level with respect to time for a dubbed recording, TDR*, is given

approximately by:

ni/2

TDR* * TDR^ + E f LD,^ (1.3)

where TDR is as defined in Section 2.5.2 and LD. is the root-mean-square value

of dL/dt, for the i-th single-event, over the time period T^. This value of TDR

can be used, in conjunction with LEQ* from Eq. (l.l), to obtain an approximation

to the LEQP value corresponding to the dubbed recording.

The other noise descriptors (LI, LIO, L50, L90, L99, TNI, SIG, and LNP) for

a dubbed recording could, with certain assumptions, be computed from the cumulative distribution functions for the multiple-event recording and for the singleevent recordings. However, it is easier simply to compute the synthesized time

history directly and then use it to obtain these descriptors.

I-l
In order to check the validity of Eqs . (I.l), (1.2), and 1.3),

two synthesized time histories were generated and the twelve noise

descriptors corresponding to each of these time histories were

calculated. These calculated values are compared with the predictions

of Eqs. (I.l) through (1.3) in Tables I.l and 1.2. The singleevent recordings were dubbed in at their actually-measured levels

(they could have been adjusted relative to the multiple-event

recordings). The relative timing of the recordings was such that

the maximum A-weighted sound level for each single event occurred

midway between the times corresponding to the maximum levels for the

automobile passbys just before and just after the gap into which

the single-event passby was dubbed. In predicting the values for

LEQ, LB, and TDR, the values of SEL, SELB, and LD (total)

derived for the "10 dB down time" were used. The cumulative

probability A-weighted sound pressure level distributions for these

two synthesized time histories are plotted in Figs. I.l and 1.2.

The results shown in Tables I.l and 1.2 indicated that Eqs.

(I.l), (I. 2), and(1.3) may be used as aids in predicting values of

LEQ, LB, and TDR (and hence LEQP) for dubbed recordings.

16. ABSTRACT (A 200-worcl or leaa tactual summary of moat aignUicant information. If document includes a significant bibliography or

literature survey, mention it here.)

This report documents a traffic noise data base that was obtained as part of a large research program developed to identify and quantify the important physical

parameters which affect human response to time-varying traffic noise and to

investigate various procedures for rating such noise so as to enable reliable

predictions of subjective response to the noise. Fifteen-minute recordings of actual

traffic noise were made at four microphone positions (7.5, 15, 30, and 60 m from the

centerline of the near lane) at several times of the day at each of seven sites, five

representing nominally constant-speed traffic and two representing stop-and-go

intersection traffic. The 107 recordings that resulted were subjected to extensive

analysis. The analysis procedures are described and tables and graphs are included

which document, for each recording, the 1/3-octave band spectra and numerous noise

descriptors computed from the time-histories of the A-weighted sound level. As a separate part of this study, recordings also were made of the noise from singlevehicle passbys and from simulated traffic consisting of controlled drive-bys of up

to ten vehicles. These recordings also were extensively analyzed and the results of

these analyses are given.
