ORDER OF THE BOARD (by M.E. Tristano, G.T. Girard, T. E. Johnson):
 
The Board opened this rulemaking to propose updated regulations governing noise found
in 35 Ill. Adm. Code Subtitle H, pursuant to Sections 27 and 28 of the Illinois Environmental
Protection Act, (415 ILCS 5/27-5/28 (2002) and 35 Ill. Adm. Code Part 102 Subpart B. Many of
the sound measurement definitions and techniques in the Board’s current rules do not reflect
present scientific standards. The instant rulemaking is closely associated with recently opened
docket Noise Rule Update Amendments to 35 Ill. Adm. Code 900 and 903, R03-08 (R03-8) that
defines acoustical terms, pollution sources and sound measurement procedures. R03-8 is also
based on updated science, including pertinent American National Standards Institute updates
from 1998-2001, and other current scientific publications. Noise Rule Update Amendments to
35 Ill. Adm. Code 900 and 903, R03-08 (Dec. 19, 2003)
slip op
at 2.
 
The instant proposal revises outdated numerical sound emission standards for property
line noise sources found at 35 Ill. Adm. Code Parts 901. In addition, the proposal adds Part 910
to the Board’s rules that incorporates noise measurement techniques currently contained only in
Illinois Environmental Protection Agency (Agency) rules at 35 Ill. Adm. Code 951.
 
BACKGROUND
 
The Board’s noise rules have not been updated since 1983 and 1987. In 1990, the
Department of Energy and Natural Resource
1
(DENR) contracted Dr. Paul Schomer of the
University of Illinois to examine the adequacy of Illinois noise regulations, and, particularly
whether the existing rules were adequate to regulate discontinuous noise. Dr. Schomer’s report,
“Impulse Noise Study”, (ILENR/RE-EA-90-16, printed November 1990, Springfield, IL)
suggested some adjustments in the Board’s noise regulations. In 1991, DENR contracted for an
additional report by Dr. Schomer, entitled, “Proposed Revisions to Property Line Noise Source
Measurement Procedures”, (ILENR/RE-EA-91/10, printed June 1991, Springfield, IL),
describing and developing a systematic set of procedures for noise measurements.
 
1
In 1995, the Department of Natural Resources Act P.A. 89-50 (eff. July 1, 1995) (20 ILCS
5/801
et seq
. (2002)
 
merged DENR into the Department of Natural Resources.

2
 
During the summer of 1991, the Board prepared a proposal that attempted to
translate the Schomer reports into regulatory language (Amendments to 35 Ill. Adm.
Code Subtitle H Noise-Pertaining to Definitions, Measurement Procedures, and Sound
Emission Standards Relating to Certain Noise Sources, R91-25 (Oct. 24, 1991)). An
inquiry hearing based on the document was held on November 25, 1991, in Chicago,
Illinois, in which testimony was presented. The Board’s proposal was based on revising
the noise measurement procedures at Section 900.103(b) and the impulsive sound
standards at Section 901.104. In addition, the Board proposed incorporating Agency
noise measurement procedures found at 35 Ill. Adm. Code 951 into Board regulations at
35 Ill. Adm. Code Part 910, by modifying the Part 951 language to incorporate the
recommendations contained within the Schomer reports. In 1992, the Board closed the
R91-25 docket before proceeding to first notice with proposed changes to the Board’s
noise rules.
 
The need to update the Board’s noise rules to conform to current scientific
procedures has become more apparent during the past ten years. The Board has
identified necessary improvements in several areas. In the instant rulemaking, the Board
proposes changes in Parts 901 and 910. In Part 901, the Board proposes to replace the
references to the Standard Land Use Coding System (SLUCM) codes with the more
appropriate Land-Use Based Classification System. New rules in Part 910 are proposed
to incorporate Agency noise measurement procedures found at 35 Ill. Adm. Code 951. In
the companion rulemaking, R03-08, which went to first notice on December 19, 2002,
the Board proposed changes in Parts 900 and 903 of the noise rules. In Part 900,
definitions and technical references have been updated. Part 903 needs to be repealed
because the Illinois legislature has removed the authority for the rules.
 
DISCUSSION
 
The Board will explain each section of the rule in the following discussion.
 
35 Ill. Adm. Code 910: Measurement Procedures for the Enforcement of 35 Ill. Adm.
Code 900 & 901
 
 
The proposed new Part 910 sets forth the measurement procedures for enforcing
the Board’s noise standards in Parts 900 and 901. These procedures are essentially based
upon the Agency’s noise measurement protocols at 35 Ill. Adm. Code 951. As noted
above, the Board has made a number of substantive changes to the Agency’s
measurement protocols to reflect the recommendations of the DENR’s noise reports. A
brief description of the proposed procedures is provided below.

3
 
Section 910.100 General
 
This Section sets forth the scope of the proposed noise measurement procedures
and techniques. The Board has deleted references to “Agency personnel”, since the
measurement procedures are applicable to any person conducting noise measurements to
demonstrate compliance with Parts 900 and 901.
 
Section 910.101 Personnel Qualification
 
The Board decided not to incorporate the Agency’s personnel qualification
requirements in the instant proposal since they are specific to Agency personnel, and also
because the requirements are not based on any State approved licensing or certification.
 
Section 910.102 Instrumentation
  
 
This section sets forth the requirements for sound measuring equipment, sound
indicating devices such as magnetic tape recorder or graphic level recorder, and weather
measuring instruments. These requirements are the same as that in Part 951, except for
the updated references to the ANSI (American National Standards Institute), and the
International Electrotechnical Commission (IEC) standards. See changes at Section
910.102(a).
 
Section 910.103 Definitions
 
The Board has moved all pertinent definitions found in the Agency’s regulations
to 35 Ill. Adm. Code 900.103, which contains the definitions applicable to the Board’s
noise regulations.
 
Section 910.104 Measurement Techniques for 35 Ill. Adm. Code 900
 
This section clarifies that while sound pressure level measurements are not
required to establish a violation of the Board’s nuisance noise standard at 35 Ill. Adm.
Code 900.102, such measurements may be used as corroborating evidence. In this
regard, the proposal requires a person conducting sound measurements to comply with
the instructions of the sound measurement equipment manufacturer. Further, Section
910.104 sets forth that the measurement techniques proposed at Section 910.105 may be
used as guidance. While the proposed approach deviates from the detailed sound
measurement requirements specified in Part 951, the Board believes that the proposed
approach is consistent with the Board’s precedence and case law concerning nuisance
noise complaints.
 
Section 910.105 Measurement Techniques for 35 Ill. Adm. Code 901
 
The measurement techniques for obtaining sound pressure levels to demonstrate
compliance with Part 901 standards are essentially the same as the Agency’s regulations,
except for the deletion of measurement procedures for steady sound, fluctuating sound,

4
 
intermittent sound, impulsive sound, and quasi steady sound set forth at Sections 910.105
(d)(3) through (d)(7), respectively. The Board notes that these measurement procedures
are addressed by the measurement techniques for highly-impulsive sound set forth at
Section 910.107.
 
Section 910.106 Protocols for Determination of Sound Levels
 
This section sets forth a systematic set of procedures for determination of
equivalent sound level (Leq) using as an example the determination of a 1-hour Leq
corrected for background ambient sound. The proposed protocols are based on the
recommendations of the Department’s noise study entitled “ Proposed Revisions to
Property Line Noise Source Measurement Procedures.” These protocols prescribe
detailed data collection requirements, and equations for averaging sound data on an
energy basis. In addition, Section 910.106 prescribes procedures correcting the raw
equivalent sound level for background ambient sound. The proposal also prescribes
detailed procedures for measuring background ambient sound that include both direct
measurement methods and the use of Tables of long-term background ambient.
 
Section 910.107 Measurement Techniques for Highly-Impulsive Sound under
35 Ill. Adm. Code 901.104
  
Two equally valid methods are proposed for measuring highly-impulsive sound.
The first method, termed as the “General Method” at Section 901.107(b), provides for A-
weighted Leq measurement using the procedures set forth in Sections 910.105 and
910.106. The second method, which is referred to as the “Controlled Test Method” at
Section 910.107(c), involves the determination of total sound exposure per hour. Again,
the Board notes that the proposed protocols are based on the Department’s noise study.
 
35 Ill. Adm. Code 901: Sound Emission Standards and Limitations for Property Line-
Noise-Sources
 
The proposed changes to Part 901 update the existing Standard Land Use Coding
Manual (SLUCM) based land classification, and revise the impulsive sound standards. A
brief description of the proposed changes is provided below.
 
Section 901.101 Classification of Land According to Use
 
The changes proposed to this section update the existing land use classification,
which is based on SLUCM codes, with the Land-Based Classification Standards (LBCS)
codes. The Board notes that the LBCS, which replaced the 1965 SLUCM, provides a
consistent model for classifying land uses based on a multi-dimensional land use
classification model. While the LBCS provides for classification of land use based on
activity, function, structure type, site development character, and ownership, the Board is
proposing to update the SLUCM codes with the LBCS function codes. In this regard, the
Board believes that the LBCS functional categories are very similar to the SLUCM
categories listed in the existing regulations at Part 901, Appendix B.

5
 
 
Consistent with the changes proposed to Section 901.101, the instant proposal
also updates the SLUCM Codes Table in Part 901, Appendix B with the LBCS function
codes. For more detailed information concerning the LBCS, the Board directs interested
persons to review the LBCS executive summary or visit the LBCS web page
(www.planning.org/LBCS ).
 
Section 901.104 Highly-Impulsive Sound
 
The proposed changes to Section 901.104 clarify that the impulsive sound
standards are based on 1-hour A-weighted equivalent sound levels, and revise the
numeric standards. The revisions to the numeric limits for highly-impulsive sound are
based on the recommendations of the Department’s Impulse Noise Study. These
revisions are intended to bring highly impulsive noise standards into conformity with the
standards set forth in Sections 901.102 and 901.103 in terms of the effective community
response. A more detailed discussion of the proposed revisions may be found in the
proposal.
 
Section 901.109
 
Highly-Impulsive Sound From Explosive Blasting
 
 
Based on the recommendations of the Department’s noise study, the Board has
revised the peak level limits to be consistent with the U.S. Bureau of Mines requirements.
The proposal also specifies lower limits for multiple events in one day. In addition, the
instant proposal clarifies when the daytime and nighttime hours begin and end. The
Board has also changed the reference to SLUCM codes to LBCS codes.
 
CONCLUSION
 
The Board will proceed to public notice with the following proposal. The Board
will hold hearings and accept comment on the proposal prior to determining whether or
not to proceed to first notice.
 
To facilitate understanding of the possible modifications to Ill. Adm. Code 35 Part
951 suggested as part of this Rulemaking, the Board edited that document using the
traditional strike through and underlining approach to new language. The Board
encourages interested persons to contact the hearing officer to be added to the notice list.
  
ORDER
 
The Board adopts this proposal for public comment. The Board intends to
conduct two pre-first notice hearings on the proposal, one in Chicago and one in
Springfield.

operational level from the Board. A permanent site specific level
is that level of operation allowed petitioner after review and
approval by the Board and after implementation of abated
measures, if any, approved by the Board.
 
2) Any existing impact forging operation seeking a permanent site
specific operational level must submit as its petition the following:
 
A) The location of the petitioner, a description of the
surrounding community, and a map locating the petitioner
within the community;
 
B) A description of the petitioner's operations, the number and
size of the petitioner's forging hammers, the current hours
of hammer operation, the approximate number of forgings
manufactured during each of the three prior calendar years
and the approximate number of hammer blows used to
manufacture the forgings.
 
C) A description of any existing sound abatement measure.
 
D) The sound levels in excess of those permitted by
subparagraph (c) emitted by the petitioner into the
community, in 5 decibel increments measured in Leq,
shown on the map of the community.

F) A description of other significant sources of noise (mobile
and stationary) and their location shown on the map of the
community;
 
G) A description of the proposed operational level and
proposed physical abatement measures, if any, a schedule
for their implementation and their costs;
 
H) The predicted improvement in community sound levels as a
result of implementation of the proposed abatement
measures; and
 
I) A description of the economic and technical considerations
which justify the permanent site specific allowable
operational level sought by petitioner.
 
3) An existing impact forging operation seeking a permanent site
specific operational level shall prepare and file its petition with the
Board and Agency as applicable no later than December 1, 1983.
 
4) The Agency shall prepare a written evaluation regarding each
petition seeking a permanent site specific operational level and
shall file said evaluation within ninety (90) days following receipt
of the petition with both the Board and the petitioner.
 
e) Land Use Classifications Preserved
 
The land use classifications in effect within a one-mile radius of an
existing impact forging operation on September 1, 1982 shall remain the
applicable land use classification for enforcement of these rules against an
existing forging operation and any future modification thereof, regardless
of actual subsequent changes in land use unless such actual changes would
impose less restrictive limitations on the impact forging operations.
 
f) Site-Specific Operational Levels Each individual existing forging
operation identified in Sections 901.110, 901.111 and 901.112 must
comply with the site-specific operational level defined, or is otherwise
subject to Section 901.105(c).

microphone.
 
Section 910.103 Definitions
 
The definitions contained in 35 Ill. And. Code 900.101 shallwill apply to this part
 
  
"Angle of incidence": the orientation of the microphone relative to the sound
source. See Appendix A.
 
"Ambient": the all-encompassing sound associated with a given environment
without the noise source of interest.
 
"Discrete tone": a sound wave whose instantaneous sound pressure varies
essentially as a simple sinusoidal function of time.
 
(Agency Note: A discrete tone differs by definition from a prominent discrete
tone.)
 
"Fluctuating sound": a class of nonsteady sound whose sound pressure level
varies over a range greater than 6 decibels (dB) with the "slow" meter
characteristic, and where the meter indication does not equal the ambient level
more than once during the period of observation.

72
 
 
"Impulsive sound": sound characterized by brief excursions of sound pressure
(acoustical impulses) above the ambient whose duration is less than one second.
 
(Agency Note: Examples of impulsive sound sources are a drop forge hammer
and explosive blasting.)
 
"Intermittent sound": a class of nonsteady sound where the meter indicates a
sound pressure level equal to the ambient level two or more times during the
period of observation. The period of time during which the level of the sound
remains at a value different from that of the ambient is of the order of one second
or more.
 
"Noise floor": the electrical noise (in decibels) of the sound measurement system.
When the noise floor is determined by placing a calibrator over the microphone of
the sound measurement system, the noise floor may include acoustic noise due to
leakage around the calibrator.
 
"Nonsteady sound": a sound whose sound pressure level shifts significantly
during the period of observation. Meter variations are greater than + 3 dB using
the "slow" meter characteristic.
 
"Period of observation": the time interval during which acoustical data are
obtained. The period of observation is determined by the characteristics of the
noise being measured and should be at least ten times as long as the response time
of the instrumentation. The greater the variation in indicated sound level, the
longer must be the observation time for a given expected precision of the
measurement.
 
"Prominent discrete tone": sound, having a one-third octave band sound pressure
level which, when measured in a one-third octave band at the preferred
frequencies, exceeds the arithmetic average of the sound pressure levels of the
two adjacent one-third octave bands on either side of such one-third octave band
by:
 
5 dB for such one-third octave band with a center frequency from 500
Hertz to 10,000 Hertz, inclusive. Provided: such one-third octave band
sound pressure level exceeds the sound pressure level of each adjacent
one-third octave band, or;
 
8 dB for such one-third octave band with a center frequency from 160
Hertz to 400 Hertz, inclusive. Provided: such one-third octave band
sound pressure level exceeds the sound pressure level of each adjacent
one-third octave band, or;
 

73
 
15 dB for such one-third octave band with a center frequency from 25
Hertz to 125 Hertz, inclusive. Provided: such one-third octave band
sound pressure level exceeds the sound pressure level of each adjacent
one-third octave band.
 
"Property-line-noise-source": any equipment or facility, or combination thereof,
which operates within any land used as specified by 35 Ill. Adm. Code 901.101 of
the Noise Regulations. Such equipment or facility, or combination thereof, must
be capable of emitting sound beyond the property line of the land on which
operated.
 
(Agency Note: The property-line-noise-source is the equipment or facility or
combination thereof that is emitting the sound to be measured. The surface of the
property-line-noise-source is not necessarily on the property line unless they are
contiguous.)
 
"Quasi-steady sound": a train of two or more acoustical impulses.
 
(Agency Note: Examples of quasi-steady sound are riveting and a pneumatic
hammer.)
 
"Reflective surface": any building, hillside, or similar object (other than the flat
ground surface) that reflects sufficient sound to affect the sound pressure level
readings obtained from a noise source. Not included as reflective surfaces are
small objects such as trees, posts, chain-link fences, fire hydrants, vegetation such
as bushes and shrubs, or any similar object.
 
"Sound level": in decibels, a weighted sound pressure level determined by the use
of metering characteristics and frequency weightings specified in ANSI,
§1.4-1971 "Specification for Sound Level Meters."
 
(Agency Note: The sound level may be obtained by the use of a metering
characteristic and the weightings A, B, C (or other).)
 
"Sound pressure level": in decibels, 20 times the logarithm to the base 10 of the
ratio of the magnitude of a particular sound pressure to the standard reference
pressure. The standard reference pressure is 20 micronewtons per square meter.
 
"Steady sound": a sound whose sound pressure level remains essentially constant
(that is, meter fluctuations are negligibly small) during the period of observation.
Meter variations are less than or equal to + 3 dB using the "slow" meter
characteristic.
 
Section 910.104 Measurement Techniques for 35 Ill. Adm. Code 900
 

74
 
Sound pressure level measurements are not required to establish a violation of 35 Ill.Adm.Code
900.102 (nuisance noise). However, sound pressure level measurements may be introduced as
corroborating evidence when alleging a violation of 35 Ill. And. Code 900.102. If sound
pressure level measurements are collected, manufacturer’s instructions must be followed for the
equipment used and 35 Ill. Adm. Code 910.105 may be used as guidance in gathering data.
 
 
Section 910.105 Measurement Techniques for 35 Ill. Adm. Code 901
 
Sound pressure level measurements must be obtained in accordance with the following
measurement techniques to determine whether a noise source is in compliance with 35 Ill. Adm.
Code 901 of the Noise Regulations:
 
a) Site Selection
 
1) Measurements may be taken at one or more microphone positions within
the appropriate receiving land. Measurement instruments shall must be set
up outdoors within the boundaries of the receiving land for the purpose of
determining whether a noise source is in compliance with Part 901.
 
2) Measurement instruments shall must be set up not less than 25 feet
(7.6 meters (m)) from the property-line-noise-source. The 25-foot (7.6 m)
set back requirement is from the noise source and not the property line
unless the noise source is contiguous to the property line.
 
3) Other measurement locations may be used for investigatory purposes such
as, but not limited to, the following:
 
A) Determining the extent of noise pollution caused by the source of
sound;
 
B) Determining the ambient; and
 
C) Analyzing those acoustical parameters that describe the sound
source
 
4) For measurements of sound sources with no audible discrete tones,
microphones should not be set up less than 25 feet (7.6 m) from any
reflective surface which may affect data. If measurements must be taken
within 25 feet (7.6 m), the effect, if any, of the reflective surface on the
measured data must be determined.
 
5) For measurements of sound sources with audible discrete tones
microphones should not be set up less than 50 feet (15.2 m) from any
reflective surface which may affect data. If measurements must be taken

75
 
within 50 feet (15.2 m), the effect, if any, of the reflective surface on the
measured data must be determined.
 
6) Objects with small dimensions (trees, posts, bushes, etc.) should not be
within 5 feet (1.5 m) of the microphone position. If measurements must
be taken within 5 feet (1.5 m) of such objects, the effect, if any, on the
measured data must be determined.
b) Instrumentation Set Up
 
1) A tripod shall must be set over at the chosen site. The tripod shall be
extended to a height between 3 feet 8 inches (1.12 m) and 4 feet 10 inches
(1.47 m) above ground.
 
2) A microphone shall must be attached to the appropriate end of a 5-foot
(1.5 m) or longer cable and shall must be affixed to the top of the tripod.
The other end of the cable shall be connected to the measuring instrument
 
3) The angle of incidence of the microphone shall must be adjusted to that
which will yield the flattest frequency response in accordance with the
manufactures specifications.
 
4) The measuring instrument should be separated from the microphone so as
to minimize any influence on the measurements. The cable movement
must be minimized during the measurement period.
 
c) Data Acquisition and Measurement Site Operation and Instrument Calibration
 
1) Before taking sound pressure level measurements, measure and record
(near the measurement site):
 
A) Wind speed and direction;
 
B) Ambient temperature;
 
C) Relative humidity; and
 
D) Barometric pressure.
 
2) Turn the measuring instrument on and allow the instrument to stabilize.
Monitor and record the battery condition of the calibrator and all
measuring instruments.
 
3) Turn the calibrator on at its appropriate frequency. Allow the calibrator to
stabilize and calibrate the measuring system according to the
manufacturer's specifications. After the measuring system has been

76
 
calibrated, remove the calibrator and attach a suitable windscreen to the
microphone.
 
4) Adjust the microphone to the angle of incidence that will yield the flattest
frequency response in accordance with the manufacturer's specifications.
 
5) Measure the sound pressure level data within the limitations of subsection
(d) and according to the manufacturer's recommended procedures. Other
sound pressure levels may be used for investigatory purposes such as, but
not limited to, the following:
 
A) Determining the extent of noise pollution caused by the source of
sound;
 
B) Determining the ambient; and
 
C) Analyzing those acoustical parameters that describe the sound
source.
 
6) While sound measurements are being taken, the operator must be
separated from the microphone so as to minimize any influence on the
measurements.
 
7) While measurements are being taken, visual and aural surveillance of
extraneous sound sources and varying wind conditions should must be
made to insure that the conditions of measurement are accurately known.
Record any variations in these parameters that may affect data. The
number and basis for each bad or corrupted affected data block shall must
be recorded. When using a tape recorder, voice commentary concerning
conditions shall will be recorded on the cue track.
 
8) To minimize wind effects on the microphone, sound measurements shall
must not be taken when the wind velocity is greater than 12 miles per hour
(5.4 m/second) at the microphone position.
 
9) For the purposes of data correction, the ambient sound at the measurement
site must be determined by means of measurement or analysis.
 
10) After taking sound pressure level measurements, remove the windscreen
and attach the calibrator to the microphone. Turn the calibrator on at its
appropriate frequency. After allowing the calibrator to stabilize, monitor
and record the measuring system response. When the measuring system
response varies by more than + 0.5 dB from the most recent field
calibration, the sound pressure level measurements obtained since such
most recent field calibration shall not be used for enforcement purposes.
 

77
 
11) Before removing the calibrator from the microphone, turn the calibrator
off. If the ambient has not been determined by means of measurement,
determine the noise floor of the measuring system. If the noise floor is
within 10 dB of the measured sound pressure level data, such noise floor
measurements shall must be recorded.
 
12) At the end of the sound survey, monitor and record the battery condition
of the calibrator and all measuring instruments. Near the measurement
site, measure and record:
 
A) Windspeed and direction;
 
B) Ambient temperature;
 
C) Relative humidity; and
 
D) Barometric pressure.
 
13) Record the physical and topographical description of the ground surface
within the vicinity of the measurement site, survey site location, a
description of the sound source, a diagram of the area, the location of
reflective surfaces near the microphone, and the approximate location of
the noise source relative to the microphone position.
 
14) Use of A magnetic tape recorder is used to preserve the raw data is
encouraged. Calibration signals shall must be recorded at the beginning
and end of each tape as well as at intermediate times such as when
relocating to a new measurement site occurs. Voice commentary
concerning local conditions and bad or corrupted affected data blocks shall
must be recorded on the cue track. The original tape recording shall must
be preserved for subsequent evaluation. Laboratory analyses may be
performed on magnetic tape recorded field data. A description of the
laboratory instrumentation and procedures shall must be recorded.
Analyses used in the laboratory shall must be correlated to field
measurement techniques.
 
d) Limiting Procedures for Specific Types of Data Acquisition
 
1) For measurements of non-impulsive sound with audible discrete tones,
one-third octave band sound pressure levels shall must be obtained in
determining whether a noise source is in compliance with 35 Ill. Adm.
Code 901.106 of the Noise Regulations.
 
2) For measurements of non-impulsive sound with no audible discrete tones,
octave band sound pressure levels shall must be obtained in determining

78
 
whether a noise source is in compliance with 35 Ill. Adm. Code 901.102
and 901.103 of the Noise Regulations.
 
 
3)
Steady sound:
 
A)
For measurements of steady sound at one or more octave or
one-third octave bands, sound pressure level measurements shall
be obtained for such octave or one-third octave bands. The
average of the maximum and minimum sound pressure levels shall
be obtained for each octave or one-third octave band center
frequency during the period of observation (See Appendix C,
Figure 1).
 
B)
For measurements of steady sound that varies between two or more
levels when observed using the "fast" or "slow" meter
characteristic, the average sound pressure level for the steady level
of interest shall be obtained (See Appendix C, Figure 2).
 
C)
For steady sound whose duration is five seconds or more the "fast"
or "slow" meter characteristic shall be used. For levels that are
steady for one to five seconds the "fast" meter characteristic shall
be used.
 
4)
Fluctuating Sound:
 
A)
For measurements of fluctuating sound at one or more octave or
one-third octave bands where the fluctuations on the indicating
meter are between + 3 dB and + 5 dB ("slow" meter characteristic),
obtain the sound pressure level 3 dB below the maximum level.
This corresponds to the root mean square (rms) sound pressure
level and shall be obtained for such octave or one-third octave
bands (See Appendix C, Figure 3). When successive fluctuations
are observed to have different maximum levels, obtain the sound
pressure level 3 dB below the mean of the maximum levels for
several excursions.
 
B)
For measurements of fluctuating sound at one or more octave or
one-third octave bands where the fluctuations on the indicating
meter are greater than + 5 dB, the sound pressure level may deviate
from the true rms value by several decibels (See Appendix D,
Figure 1). The recorded level shall be obtained by reading the
maximum level of the sound level meter 10 or more times during
the period of observation. The recorded level shall be obtained
from the following equation:
 
 
N

79
 
L = 10 log 1/N 10
L
i
/10
 
i=1
 
where
N = the total number of observations
 
L
i
= the maximum level at each observation
 
C)
For measurements of fluctuating sound that varies between two or
more levels when observed using the "slow" meter characteristic,
the measurement methods specified in subsection (d)(4)(A) or
(D)(4)(B), may be used to obtain sound pressure levels for the
fluctuating level of interest (See Appendix D, Figure 2).
5)
Intermittent Sound: For measurements of intermittent sound the methods
specified in subsections (d)(1), (d)(2), (d)(3) or (d)(4) shall be used during
the time the sound exceeds the ambient level (See Appendix D, Figure 3).
 
6)
Impulsive Sound: For measurements of impulsive sound, A-weighting
and the "fast" meter characteristic shall be used. The maximum excursion
of the indicating meter shall be obtained. Measurements may also be
taken using other weightings and meter characteristics for informational
purposes (See Appendix E, Figure 1).
 
7)
Quasi-Steady Sound: For measurement of quasi-steady sound,
A-weighting and the "fast" meter characteristic shall be used. The
maximum excursion of the indicating meter shall be obtained.
Measurements may also be taken using other weightings and meter
characteristics for informational purposes (See Appendix E, Figure 2).
 
e) Correction Factors
 
If necessary, correction factors rounded to the nearest 1/2 decibel shall must be
applied to sound pressure level measurements. The correction factors applicable
to the measurement system may include, but are not limited to, corrections for
windscreen interference and the sound pressure level difference between
consecutive field calibrations. Such calibration correction factors shall must only
be used to make negative corrections (subtraction from the field data). In no case
shall must such calibration correction factors be added to the measured sound
pressure levels so as to raise the sound pressure level field data. The correction
factors applicable to the measurement site may include, but are not limited to,
corrections for reflective surfaces and ambient sound.
 
Section 910.106 Protocols for Determination of Sound Levels
 

80
 
a) The raw data collection procedures for the determination of equivalent sound
level (Leq) are described in this section using as an example the determination of a
1-hour equivalent sound level (Leq) corrected for background ambient. The
following procedures shall must be used:
 
1) Using small blocks:
 
A) The 1-hour interval is divided into many small blocks of time such
that corruption of the data from short-term background transient
sound and loss of data can be limited to the corrupted or bad
blocks. The block duration in seconds, shall must remain fixed for
any measurement hour. The duration shall must be neither less
than 10 seconds nor greater than 100 seconds. For example, if the
block duration is chosen to be 60 seconds (1 minute), then the data
collection proceeds for 60, 1-minute periods of measurement.
B) The collected data shall must be the block duration Leq (or sound
exposure level (SEL)) in octave bands (or 1/3-octave bands if
prominent discrete tones may be present).
 
C) Data for any block corrupted by one or more short-term
background transient sounds shall must be deleted.
 
D) After deleting corrupted data blocks, there will be a fixed number
of “good” data blocks remaining. This number is designated as
NPLNS, where PLNS stands for Property-Line-Noise-Source. These
remaining “good” blocks shall must be numbered consecutively.
The subscript i is used to denote the numbering of the blocks in
time order after corrupted data blocks have been deleted.
 
E) The data for the NPLNS remaining blocks are averaged on an energy
basis by octave (or 1/3-octave band) using Equation 1 below. In
this equation, two subscripts are used, i to designate time and j to
designate the specific frequency, either an octave band or 1/3
octave band. The raw 1-hour Leq. The raw, 1-hour Leq in the
j
th
frequency band is give by:
 
 
[Equation 1]
 
where Lequij is the Leq in the
j
th frequency band for the
i
th non-
deleted data block.

an hour.
 
2) Continuous Data Collection.
 
A) The measuring instrument shall must be adjusted to continuously
measure and accumulate Leq for each block of time. For
convenience, the hour may be split into several smaller blocks such
as 10, 6-minute blocks or 4, 15-minute blocks, etc.
 
B) A switch on the measuring instrument shall must be available to
inhibit data collection whenever a short-term background transient
sound occurs. This switch shall be used to prevent short-term
background ambient sounds from corrupting the data.
 
 
C) Data collection shall must proceed for one hour. The energy
average of the several measured Leqij each weighted by the number
of seconds actually accumulated during the
i
th block results in the
raw, 1-hour Leq in each frequency band given by:

3) Minimum data collection requirements:
 
A) Initial Measurement Duration.
The property-line-noise-source
measurements shall must proceed initially for one hour. Because
of correction for short-term background transient sounds, actual
reported data collection time T, in seconds, may be less than 3600
(one hour).
 
i) If small blocks of data are used for data collection,
then the total measurement duration in seconds,
TPLNS is given by NPLNS T, where T is the length of
each block in seconds and NPLNS is the number of
non-discarded blocks. If data inhibition is used for
data collection, then TPLNS is the number of non-
inhibited seconds during the measurement hour. In
either case, TPLNS shall be no less than 900 seconds.
 
ii) If very few blocks were used for data collection,
then the duration of each block, T, may be too long
and should be reduced.
 
iii) For either data collection method, sounds
considered to be short-term transient may actually
be part of the long-term background ambient and
should be so redefined.
 
B) Extended Measurement Duration. If TPLNS is less than 900 seconds
during the first hour of measurements, the raw data collection
procedures shall be appropriately modified and new measurements
shall must proceed for an additional hour. If TPLNS after
combining the first and the second hour of measurements is also
less than 900 seconds, then the raw data collection shall must
continue using the data inhibition method or method employed
during the second hour until TPLNS is greater than or equal to 900
seconds.
 
4) Correction for Long-Term Background Ambient Sound:
 
A) The raw, 1-hour Leq shall must be corrected for long-term
background ambient sound. Subsection (a) (4) (5) below describes
methods to obtain the long-term background ambient sound level
in the jth frequency band. The correction is dependent on the

83
 
difference (in decibels) between the raw, 1-hour, jth band property-
line-noise-source Leqj and corresponding jth band long-term
background ambient sound level. The correction to be applied is
as follows:
 
i. If the difference between the raw1-hour Leq and the
long-term background ambient sound is larger than
10 decibels, then the correction shall be set to 0.
 
ii. If the difference between the raw 1-hour Leq and the
long-term background ambient sound difference is
less than 3 decibels, then the
j
th frequency-band
level, Leqj, shall be set equal to 0.
 
 
iii. If the difference between the raw 1-hour Leq and the
long-term background ambient sound is between 3
and 10 decibels then the correction given in Table 1
below shall be subtracted from the raw, 1-hour
property-line-noise-source Leqj
 
Table 1

5 1.7
 
6 1.3
 
7 1.0
 
8 0.7
 
9 0.6
10 0.5
 
B) The long-term background ambient corrected level shall must be
the property-line-noise-source Leqj reported for the jth frequency
band.
 
b) Obtaining the background ambient sound level:
 
1) The background ambient shall must be measured for the purposes of this
section during a 10-minute interval.
 

84
 
2) Long-term background ambient measurement procedures are similar to
procedures to measure the property-line-noise-source itself. Eliminating
short-term background ambient transient sounds from the measurement of
average long-term background ambient sound proceeds in a manner
similar to the measurement of the property-line-noise-source emissions
themselves. The two methods for measurement are: (1) to divide the 10-
minute measurement into short blocks of data, or (2) inhibit data collection
when short-term background transient sounds occur. The same method
shall must be used for gathering both the long-term background ambient
data. The measurement procedures for each method are given in
subsections (b) (3), (b) (4) and (b) (5) below:
 
3) Using small blocks of data
 
A) The 10-minute measurement of long-term background ambient
shall must be divided into short measurement blocks. The duration
of these blocks shall remain constant during the entire
measurement, both when measuring the long-term background
ambeint and when measuring the property-line-noise-source. The
duration of this measurement block in seconds, T, shall must
divide exactly (without remainder) into 600 and shall must be
higher neither greater than 100 seconds nor less than 10 seconds.
 
B) All data for any measurement block corrupted by one or more
short-term ambient transient sounds shall must be discarded. The
number of remaining, non-discarded measurement blocks is
designated NBA, where
BA
stands for background ambient.
 
C) The Leq for each octave (or 1/3 – octave) band are (energy)
averaged over the NBA remaining measurement blocks to obtain
average long-term background ambient Leq per band. Equation 1
(see subsection (a) (1) (E) above) is used for this calculation with
NBA replacing NPLNS as the number of elemental blocks to be
summed. The total duration of the measurement in seconds, TBA,
is given by NBA multiplied by T.
 
4) Continuous Data Collection.
 
A) The measuring instrument shall must be adjusted according to
manufacturer’s instructions to continuously measure and
accumulate (i.e record) Leq. A switch shall must be available to
inhibit data collection whenever a short-term background transient
sound occurs, (and on some instruments, a button may be available
to delete the most recent, previous data).
 

85
 
B) The switches or buttons shall must be used to prevent short-term
background ambient sounds from corrupting the data.
 
C) Data collection shall must proceed for 10 minutes. The result is
the 10-minute, long-term background ambient Leq in each band.
D) TBA is the number of non-inhibited measurement seconds during
the 10-minute measurement period.
 
5) The minimum duration, for either method, TBA shall must be no less than
150 seconds. If TBA is less than 150 seconds, then the measurement of the
long-term background ambient shall must continue beyond the original 10
minutes and until TBA for the total long-term background ambient
measurement is greater than or equal to 150 seconds.
 
6) Measurement Alternatives. The long-term background ambient-noise
should ideally be measured at the potential violation site just before
measurement of the property-line-noise-source emissions. However,
turning off the property-line-noise-source may not always be possible.
The following are a hierarchical order of five procedures for obtaining the
long-term background ambient noise. The first four procedures involves
direct measurement; the fifth procedure provides for use of tables of
values obtained from extensive measurements. These are not equivalent
procedures but are ordered from what shall be is considered to be the
most accurate to what shall is considered to be the least accurate
procedure.
 
A) Direct Measurement Procedure –1: With the property-line-noise-
source (PLNS) turned off measure the long-term background
ambient noise within the hour before or within the hour after
measurement of the PLNS emissions at the location where the
PLNS measurements are being taken and with the measurement
equipment used for the PLNS measurements.
 
B) Direct Measurement Procedure-2: With the PLNS turned off,
measure the long-term background ambient during a similar time
period in terms of background ambient sound level, within one (1)
to twenty-four (24) hours before, or within one (1) to twenty four
(24) hours after measurement of the PLNS emissions at the
location where the PLNS measurements are being taken and with
the measurement equipment used for the PLNS.
 
C) Direct Measurement Procedure- 3: With the PLNS turned off,
measure the long-term background ambient during some other
acoustically similar period within one (1) to thirty (30) days
before, or within one (1) to thirty (30) days after measurement of
the PLNS emissions. This alternate long-term background ambient

86
 
measurement time might be a Saturday night or anytime during a
Sunday or holiday. The measurements would be made at the
location where the PLNS measurements are being taken and with
the measurement equipment (or like equipment) used for the PLNS
measurement.
 
D) Direct Measurement Procedure-4: With the PLNS turned off,
measure the long-term background ambient noise during some
other acoustically similar period within thirty (30) to ninety (90)
days before, or within thirty (30) to ninety (90) days after
measurement of the PLNS emissions. These measurements would
be made at the location where the PLNS measurements are being
taken and with the measurement equipment (or like equipment)
used for the property-line-noise-source measurements.
 
E) Tables of long-term background Ambient Noise. Where none of
the alternatives can be used, use the applicable long-term
background ambient data taken from Tables 2 through 5. These
tables are organized by predominant land use and time of day
(daytime or nighttime). There are separate tables for octave and
1/3- octave bands. The background environments presented in the
table are based on extensive measurements conducted in the
Chicago area and are divided into the five categories given below
in accordance with Bonvallet, G.L., “Levels and Spectra of Traffic
of Traffic, Industrial, and Residential Area Noise,” Jornal of the
Acoustical Society of America, 23 (4), pp 435-439, July, 1951; and

Edition, Cyril M Harris, Editor , McGraw-Hill
Book Co., New York (1991).
 
i) Category 1: Noisy commercial and Industrial Areas. Very
heavy traffic conditions such as (a) in busy downtown
commercial areas, (b) at intersections of mass
transportation and other vehicles including L trains, heavy
motor trucks and other heavy traffic, and (c) street corners
where many motor vehicles, buses and heavy trucks
accelerate.
 
ii) Category 2: Moderate Commercial and Industrial Areas,
and Noisy Residential Areas. Heavy traffic areas with (a)
conditions similar to (1) above but with somewhat less
traffic, (b) routes of relatively heavy or fast automobile
traffic but where heavy truck traffic is not extremely dense,
and (c) motor bus routes.
 

87
 
iii) Category 3: Quiet Commercial and Industrial Areas, and
Moderate Residential Areas. Light traffic conditions where
no mass transportation vehicles and relatively few
automobiles and trucks pass, and where these vehicles
generally are travel at low speeds. Residential areas and
commercial streets and intersections with little traffic
comprise this category.
iv) Category 4: Quiet Residential Areas. These areas are
similar to Category 3 above but for this group the
background is either is distant traffic or is unidentifiable.
 
v) Category 5: Very Quiet, Sparse Suburban or Rural Areas.
These areas are similar to Category 4 above but are usually
in unincorporated areas and for this group there are few if
any near neighbors.

Section 910.107 Measurement Techniques for Highly-Impulsive Sound Under 35 Ill. Adm.
Code 901.104.
 
a) Measurement of highly-impulsive sound under Rule 901.104 can be made in two
distinct and equally valid ways, namely the general method and the controlled test
method.
 
b) General Method: The general method is to measure the 1-hour, A–weighted Leq
(not the octave or 1/3 octave band levels) using essentially one of the two
procedures described in 35 Ill. Adm. Code 910.105 and 910.106.
 
1) The procedure using small blocks of time to collect data is as follows:
 
A) The hour must be divided into small blocks and the A-weighted Leq
must be measured for each of these small blocks of time. Leq must
be measured for the entire hour but data collection must be
inhibited whenever a short-term background transient sound
occurs.
 
B) The duration of each block must be held constant during the hour.
This duration in seconds must divide exactly into 900 and must be
neither greater than 100 seconds nor less than 10 seconds.
 
C) The data for any block corrupted by one or more short-term
background ambient sounds must be discarded.
 
2) The continuous data collection procedures is as follows:
A) Leq must be measured for the entire hour.

91
 
 
B) Data collection must be inhibited whenever a short-term
background transient sound occurs.
 
3) Correction for the Long-Term Background Ambient must be
accomplished using all of the other procedures and requirements
enumerated in 35 Ill. Adm. Code 910.105 and 910.106 must be complied
with in order to determine an A-weighted, 1-hour, background-ambient-
correct Leq for the highly impulsive property-line-noise-source under
study.
 
c) Controlled Test Method:
For this method, the following procedures must be used:
 
1) General Measurement Description
 
A) The sound exposure per impulse from each separate individual
impulsive source is measured.
B) The total sound exposure per hour from each source is the sound
exposure per event multiplied by the number of events per hour.
 
C) The grand total sound exposure (SE) per hours is the sum of the
sound exposures per hour from each of the separate individual
sources.
 
D) The reported SEL is obtained from the grand total sound exposure
(SE) per hour using the following:
 
SEL = 10 log (SE) + 94. [Eq. 7]
 
E) The equivalent level, Leq corresponding to a SEL measured or
predicted for one hour (3600 seconds) is given by:
 
Leq = SEL - 10 log (3600). [Eq. 8]
 
2) Determination of Sound Exposure per Event must be as follows:
 
A) The sound exposure per event from each, separate, individual
source must be determined by measuring the total A-weighted
sound exposure for about 10 repetitions of this source. This set of
about 10 measurements may be performed continuously over a
short period of time, or this set of measurements may be performed
over a discontinuous set of measurement periods. In either case,
the total measurement duration must be less than 100 seconds.
 
B) These separate, individual property-line-noise-source controlled
measurement must be free of any short-term ambient sounds. If

92
 
any short-term background transient sounds occur during these
measurements, then the measurement must be repeated until
measurement data, free of any corrupting short-term background
ambient sounds are obtained.
 
C) The total measured A-weighted sound exposure for this group of
about 10 repetitions must be corrected for long-term background
ambient by subtracting the A-weighted long-term background
ambient sound exposure. The sound exposure value subtracted
must be the long-term A-weighted background ambient sound
exposure per second multiplied by the number of seconds used to
measure the several source repetitions.
 
D) The reported source A-weight sound exposure per event must be
the total corrected sound exposure divided by the number of source
repetitions measured.
 
E) The background ambient must be measured for a short time, at
least 30 seconds as near in time to the source measurements as
possible, but within ½ hour. The total A-weighted long-term
background ambient sound exposure per second is the total
measured long-term background ambient sound exposure divided
by the number of seconds of background ambient measurement.
 
F) There must be no short-term background ambient sounds present
during the measurement of the long-term background ambient. If
any short-term background transient sounds occur during these
measurements, then the measurements must be repeated until long-
term background ambient measurement data free of any corrupting
short-term background ambient sound are obtained.
 
 
IT IS SO ORDERED.
 
I, Dorothy M. Gunn, Clerk of the Illinois Pollution Control Board, certify that the Board
adopted the above order on February 20, 2003, by a vote of 7-0.
