(Rulemaking - Noise)
 
Proposed Rule. Second Notice.
 
OPINION AND ORDER OF THE BOARD (by G.T. Girard):
 
Pursuant to Sections 27 and 28 of the Illinois Environmental Protection Act (Act), (415
ILCS 5/27-5/28 (2004)) and 35 Ill. Adm. Code 102.Subpart B, on February 20, 2003, the Board
opened this rulemaking to propose updated regulations governing noise found in 35 Ill. Adm.
Code Subtitle H. Many of the sound measurement definitions and techniques in the Board’s
current rules do not reflect present scientific standards. The instant proposal revises outdated
numerical sound emission standards for property line noise sources found at 35 Ill. Adm. Code
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. The Board today proposes for second notice the
amendments.
 
BACKGROUND
 
The Board opened this rulemaking by issuing a draft for public comment on February 20,
2003. The Board elicited comments on the draft prior to first-notice publication and the Board
held two hearings before Hearing Officer William F. Murphy. The first hearing was held in
Springfield on May 1, 2003, no members of the public attended that hearing. The second
hearing (Tr.2) was held in Chicago on May 15, 2003. Joel Sternstein and Howard Chinn of the
Illinois Attorney General’s Office (AGO) attended the second hearing and Mr. Chinn presented
testimony. During the time that the proposal was offered for public comment, the Board
received two public comments, one from the AGO (PC 2) and one from Dr. Paul Schomer (PC
1).
 
On July 10, 2003, the Board proposed the rule for first notice. On July 25, 2003, the first
notice was published in the
Illinois Register
(27 Ill. Reg. 11908). The Board received five public
comments. The comments were from Scot Forge (PC 3), Vaughan and Bushnell Manufacturing
(PC 4), Illinois Association of Aggregate Producers (IAAP) (PC 5), Boughton Trucking and
Materials Inc. (Boughton Trucking) (PC 6) and Intermet Decatur Foundry (Intermet) (PC 7). In
general, the comments requested a site-specific rule modification or requested another hearing to
discuss concerns with the proposed rule.
 

 
2
On October 18, 2003, the Board determined that additional hearings should be held.
After holding an additional hearing, the Board determined on March 4, 2004, that administrative
economy supported including site-specific changes in a new first notice. Because of this
decision, the Board withdrew the first notice (
See
28 Ill. Reg. 7341, 7342 (May 21, 2004)).
 
The Board held two hearings before Board Hearing Officer Marie Tipsord. The third
hearing (Tr.3) was held February 10, 2004, in Chicago. At that hearing, Mr. John P. McGillivray
testified on behalf of Scot-Forge Company and Howard Chinn testified on behalf of the AGO.
The fourth hearing (Tr.4) was held November 4, 2004, in Springfield. Mr. John Henriksen and
Dane Tittman testified on behalf of the IAAP.
 
The Board received six additional comments during the second phase of hearings. The
comments were from Moline Forge (PC 8), Intermet (PC 9,) IAAP (PC 10), the AGO (PC 11),
Village of Bridgeview (Bridgeview) (PC 12), and the Illinois Department of Natural Resources
(IDNR) (PC 13).
 
On March 17, 2005, the Board proceeded to a second first notice with this rulemaking.
That first notice was published in the
Illinois Register
on April 15, 2005 (29 Ill. Reg. 5196). The
Board held an additional hearing on September 1, 2005 (Tr. 5) and at that hearing Mr. Henriksen
again testified along with Mr. Willard Pierce of Evenson Explosives, LLC on behalf of IAAP.
Also Mr. Jim Hafliger of the IDNR testified. The public comment period closed on October 17,
2005, and the Board received six additional comments during the 2005 first-notice period. Those
comments are:
 
PC 14 Joseph R. Angleton, Office Director, Office of
Mines and Minerals, Illinois Department of Natural
Resources
PC 15 John Henriksen, Executive Director, Illinois
Association of Aggregate Producers
PC 16 Dr. Paul Schomer, Schomer and Associates, Inc.
PC 17 Therese M. Dorigan, Bradburne, Briller & Johnson,
LLC
PC 18 Village of Bridgeview
PC 19 Dr. Paul Schomer, on behalf of Village of
Bridgeview
 
COMMENTS AND TESTIMONY
 
 
The Board received six comments along with testimony at the September 1, 2005 hearing
regarding the Board’s 2005 first-notice proposal. The following paragraphs will summarize the
comments and testimony received by the Board.
 
Testimony
 

 
3
At the September 1, 2005 hearing, Mr. John Henriksen again testified along with Mr.
Willard Pierce of Evenson Explosives, LLC on behalf of IAAP. Also Mr. Jim Hafliger of the
Illinois Department of Natural Resources (IDNR), Office of Mines and Minerals testified.
 
Mr. John Henriksen
 
Mr. Henriksen manages IAAP, which is a trade association representing companies that
produce aggregates (
i.e.
crushed sand, stone, and gravel). Tr.5 at 6-7. The companies have 113
members that operate in 80 Illinois counties and produce 111 million tons of materials. Tr.5 at 7.
The aggregate industry has been regulated for blasting by IDNR since 1995 pursuant to Section
6.5 of the Surface-Mined Land Conservation and Reclamation Act (225 ILCS 715/6.5 (2004)).
Id
. IDNR’s Office of Mines and Minerals has promulgated a set of regulations that regulate
blasting at coal mining and aggregate mining sites in Illinois pursuant to Section 3.13 of the
Surface Coal Mining Land Conservation and Reclamation Act (225 ILCS 715/3.13 (2004)) (
See
 
62 Ill. Adm. Code 300, 1816). Tr.5 at 7.
 
Mr. Henriksen testifies that IDNR’s Office of Mines and Minerals has promulgated a
comprehensive set of regulations that subjects explosives blasting at coal mining and aggregate
mining operations to air blast or ground vibration monitoring, or both, as necessary to prevent
property damage and protect public safety. Tr.5 at 7-8. Additionally, IDNR enforces the
regulations using highly trained, technologically proficient inspectors and state of the art
equipment.
Id
.
 
Mr. Henriksen states that the Board is seeking to maintain a duplicative and overlapping
regulatory program for coal mining and aggregate producers in Illinois. Tr.5 at 8. Mr.
Henriksen argues that Section 25 of the Act provides that the Board “may adopt” regulations
limiting noise emissions; however, the Board is not required to adopts such limitations. Tr.5 at
9-10. Mr. Henriksen asserts that the Board has elected not to regulate other sources of noise and
can do so here as well.
Id
. Mr. Henriksen acknowledges that the Board has the authority to
decide which activities should be regulated. Tr.5 at 10. Mr. Henriksen contends, however, that
regulation of sound generated by blasting operations at aggregate or coal mines, which are
already highly regulated by a sister agency, is unreasonable. Tr.5 at 10-11. Mr. Henriksen
suggests that Part 901 not apply to explosive operations at mines. Tr.5 at 11-12.
 
In response to questions from the Board, Mr. Henriksen states that only the sound
produced from blasting should be exempted from the Board’s rules. Tr.5 at 35. Mr. Henriksen
states that the Board should regulate steady noises that are a function of mining operations such
as sounds generated from crushing equipment and backup alarms on equipment.
Id
. However,
pursuant to Section 25 of the Act (415 ILCS 5/25 2004), Mr. Henriksen believes the Board
should defer to IDNR’s regulations on blasting at mining operations.
Id
.
 
Mr. Henriksen recommends that if the Board decides to continue to regulate the noise
emissions from blasting at mining operations, the Board should adopt a regulatory program in
harmony with IDNR’s program. Tr.5 at 13. In order for the Board’s rules to be consistent with
IDNR’s program, Mr. Henriksen suggests language changes such as limiting blasting from
sunrise to sunset and shifting the regulatory focus from the property line to protected structures.

 
4
Tr.5 at 13-14. Also, Mr. Henriksen maintains that none of the monitoring methods proposed in
Part 910 will monitor highly impulsive sound from blasting. Tr.5 at 15.
 
Mr. Jim Hafliger
 
Mr. Hafliger, whose title is Chief Division Technical Explosive Specialist in the Office of
Mines and Minerals at IDNR, testified to provide the Board with an overview of IDNR’s
program and responsibilities related to blasting at coal mines and aggregate mines in Illinois.
Tr.5 at 17. Mr. Hafliger attempts to point to areas of duplication between the Board’s
regulations and IDNR’s program.
Id
. IDNR’s program is staffed by 12 individuals in three
offices throughout the state. Tr.5 at 17-18. Eight of the staff members are full time inspectors
regulating the use of explosives in Illinois. Tr.5 at 18. Part of IDNR’s statutorily mandated
duties include regulating the use, handling and storage of explosives at the 172 active surface
mining operations in Illinois.
Id
. IDNR’s inspectors are in the field on a daily basis. These
inspectors use 35 seismographs that register and record (for analysis by IDNR’s experts) the
traces reflected as a result of air blast or air overpressure and ground vibrations at the mining
operations.
Id
.
 
IDNR’s program has been in place for many years and started with regulation of
explosive use in the 1930s. Tr.5 at 18. In the 1980s, IDNR began regulating coal blasting
operations and in the 1990s regulating blasting operations at the surface aggregate operations.
Tr.5 at 18-19. The field inspectors are trained to use the seismographs and to analyze the data.
Tr.5 at 19. IDNR regularly monitors the sites and takes a proactive stance to make sure the
operators are fulfilling their statutory obligations. Tr.5 at 20. IDNR has a comprehensive
training program for people who undertake blasting in Illinois and recently Illinois was
recognized for using an estimated 500 million pounds of explosives over a five-year period
without a reported injury. Tr.5 at 20-21.
 
IDNR’s program is enforced using a hearing process within IDNR and can include fines
or even suspension or revocation of actual blasting operations. Tr.5 at 41. The program includes
requirements for recordkeeping for each blast that incorporates every minor detail of the blast.
Tr.5 at 41-42. Mr. Hafliger testifies that there are 17 different criterion included on the blasting
records which must be available for inspection by IDNR’s staff. Tr.5 at 42-43. Furthermore,
both the mining company and the actual person performing the blasting are subject to sanctions
for violation of IDNR’s rules. Tr.5 at 43-44. Mr. Hafliger also notes that IDNR has an 800
number to be used for any complaints relating to blasting and that number has received about
100 complaints this year. Tr.5 at 44, 46.
 
Mr. Willard Pierce
 
Mr. Pierce is general manager of Evenson Explosives, which provides blasting services in
four states with a majority of that in Illinois. Tr. 5 at 23. Mr. Pierce also worked for IDNR and
helped establish and implement the blasting regulatory program at IDNR.
Id
. Mr. Pierce wishes
to ensure that the regulatory requirements are consistent and that the requirements can be
implemented. Tr.5 at 24. Mr. Pierce testifies that based on the regulations, blasters in Illinois

 
5
need two years hand on experience, as well as class room training and examination before
receiving a license. Tr.5 at 24.
 
Mr. Pierce expresses concern over the inconsistency in the C-weighted numbers between
those in Section 901.109 and IDNR’s rules. Tr.5 at 25-26. Mr. Pierce also suggests that there
should only be one standard and that standard should not deviate depending on the time of day or
the number of times a blast occurs during the day. Tr.5 at 26.
 
Mr. Pierce also testifies that an air blast is a very specific type of sound and is a very low
frequency. Tr.5 at 26. Mr. Pierce states that you do not actually “hear” an air blast but rather the
effects of the air blast.
Id
. For example, Mr. Pierce states that you may hear surface delays or
venting and you might feel the blast in your chest.
Id
.
 
Mr. Pierce indicates that about 12 years ago the International Society of Explosive
Engineers worked with manufacturers of monitoring equipment to develop standards for
monitoring air blasts from blasting. Tr.5 at 27. The standard was published in 1999 and uses the
seismograph for measuring air blast because the seismograph can measure ground vibration and
air blast. Tr.5 at 27-28. Mr. Pierce sums up his position by stating that the industry has a
standard for air blast, and a standard for monitoring which has been in place for a number of
years. Tr.5 at 29-30. Further, the standard is based on science and is protective of structures.
Tr.5 at 30.
 
Mr. Pierce notes that air blast is a short-term transient noise, that lasts about three
seconds. Tr.5 at 28. Thus, where the Board’s propose rule suggests shutting off monitoring
equipment for transient noise, the rule would seem to allow shutting down monitoring equipment
for air blasts.
Id
. Mr. Pierce recommends that if the Board chooses to adopt a rule requiring
monitoring of air blasting, that the Board require the use of a blasting seismograph for
monitoring. Tr.5 at 29.
 
Mr. Pierce summarizes his testimony by stating that he has five recommendations. The
first is that the C-weighted and flat response microphones have the same number. Tr.5 at 30.
Second, Mr. Pierce recommends that the limit for air blasts apply at a structure, not the property
line.
Id
. Third, Mr. Pierce recommends limiting blasting from sunrise to sunset, except in
emergency situations. Tr.5 at 31. Fourth, Mr. Pierce does not believe the limits should be
lowered based on the time of day.
Id
. And fifth, Mr. Pierce urges the Board to require the use of
monitoring procedures and equipment appropriate to blasting.
Id
.
 
Public Comments
 
 
As indicated by the list above the Board received six comments including two from Dr.
Paul Schomer including one on behalf of the Village of Bridgeview. The Board will group the
comments by the author of the comment.
 
Office of Mines and Minerals, IDNR
 
 

 
6
IDNR regulates blasting operations at all surface aggregate and coal mines in Illinois. PC
14 at 1. IDNR’s comprehensive regulations help prevent personal injury and property damage
though the use of the conservative limits of one inch per second ground vibration and 133dB
maximum air over pressure.
Id
. IDNR comments that these standards are nationally recognized
and accepted industry practice.
Id
. IDNR determines regulatory compliance by routinely
inspecting and monitoring blasting at all of the State’s 172 active aggregate and coal blasting
sites.
Id
. IDNR’s staff of 13 people have over 100 years of combined explosives related
experience and field inspectors trained in the technical elements of seismology regularly monitor
blasting using state-of-the-art seismographs.
Id
.
 
IDNR specifically lists several points where the Board’s proposal is inconsistent or
deviates from IDNR’s standards and IDNR recommends changes for consistency. First, IDNR
notes that the amendments to Section 901.109(a) result in limits that are inconsistent with and
less stringent than the IDNR limits. PC 14 at 1. IDNR also suggests that the limits remain
constant from sunrise to sunset and not be amended based on the time of day. PC 14 at 2. IDNR
recommends that the regulatory limits apply to the nearest protected structure rather than the
property line.
Id
. IDNR also notes that the monitoring methods in Part 910 are not conducive
for use in monitoring blasting and seismographs are specifically designed for monitoring
blasting.
Id
.
 
IDNR states that the proposed rules are trying to fit air over pressure within the scope of
intrusive noise and sound regulations when in fact the two are separate issues. PC 14 at 2.
IDNR suggests that the surface aggregate and coal mine blasting provisions in the Board’s rules
be deferred to IDNR for regulation.
Id
.
 
IAAP
 
 
IAAP’s public comment echoes the testimony of Mr. Henriksen in suggesting that the
Board can and should defer to IDNR for the regulation of blasting at aggregate and coal mining
operations. PC 15. IAAP points out that IDNR has regulated blasting operations at aggregate
mines since 1995 and surface coal mines since 1982.
Id
. IAAP suggests that if the Board does
decide to regulate blasting from mine operations, then the rules should be amended to ensure
consistency between the Board and IDNR’s regulations.
Id
.
 
Ms. Therese M. Dorigan
 
 
Ms. Dorigan filed a comment on behalf of Kropp Forge. PC 17. Ms. Dorigan notes that
Kropp Forge is not seeking any site-specific relief in this proceeding, but wishes to preserve any
right to seek site-specific relief from the Board at a future date.
Id
.
 
Dr. Paul Schomer and Village of Bridgeview
 
 
Dr. Schomer and Bridgeview reiterate the positions taken by Bridgeview at first notice
concerning both the sound monitoring personnel qualifications and sound measurement
procedures for establishing nuisance noise violation. PC 16, 18, and 19. Bridgeview also argues
that bad science and misleading evidence should not be admissible in nuisance cases any more

 
7
than in numeric violation cases and challenges the use of noise measurements in nuisance noise
enforcement proceedings. PC 18 at 1. In addition, Dr. Schomer raises concerns about the
efficacy of the Board’s rules. PC 19 at 2. The following paragraphs will summarize the
comments.
 
 
Sound Monitoring Personnel Qualifications.
Dr. Schomer comments that the lay
person taking sound measurements can make errors when taking those measurements. PC 16 at
1. According to Dr. Schomer those errors include:
 
1. A lay person does not understand or necessarily hear properly background noise;
 
2. A lay person does not understand the role that wind induced noise makes on
measurements;
 
3. A lay person does not understand the role that reflecting surfaces have on noise
measurements. PC 16 at 2-3.
 
The “implications” of errors in measurement in Dr. Schomer’s opinion is that the evidence of
noise emissions measured by a lay person is inherently unreliable. PC 16 at 3.
 
Dr. Schomer argues that the Board has a viable option in terms of identifying qualified
noise professionals. PC 16 at 5. Dr. Schomer urges the Board to require that measurements of
noise emissions be supervised by an individual who is a “Member, Board Certified, of the
Institute of Noise Control Engineering of the USA” (Institute).
Id
. Dr. Schomer states that the
Institute is a non-profit technical society and certification requires education, several years
experience, passing a rigorous 8-hour exam, and periodic professional activities to maintain
certification.
Id
.
 
Dr. Schomer notes that as a lessor option, the Board could require that a member of the
Institute, who is also a full member of the Acoustical Society of America, supervise noise
emission measurements. PC 16 at 6. Dr. Schomer opines that with such a requirement the
individual supervising the measurements “has some working knowledge of the mathematics of
acoustics and of acoustical measurement.”
Id
.
 
In Bridgeview’s final comment, Dr. Schomer states that there is one way to correctly
perform measurements, but a multitude of ways to mess up measurements. PC 19 at 1. Dr.
Schomer argues that ANSI procedures must be followed using ANSI approved methods and
instrumentation.
Id
. Dr. Schomer opines that many measurement devices sold at stores are
worthless and best used for indoor measurements.
Id
.
 
 
Sound Measurement Procedures for Establishing Nuisance Noise Violation.
Dr.
Schomer states that standards exist so that within a reasonable degree of scientific certainty, two
people can perform the same measurements under identical conditions and get the similar results.
PC 16 at 4. Dr. Schomer asserts that unless standards are followed, the Board has no valid
scientific method by which to assess the accuracy of data submitted to the Board. PC 16 at 4-5.

 
8
Dr. Schomer opines that the Board should use this rulemaking to make the standards for accurate
measurements clear for both numeric and nuisance cases. PC 16 at 5.
 
 
Efficacy of the Rules.
Dr. Schomer argues that allowing a lay person to make hand held
A-weighted measurements does a disservice to the rules and to the noise receiver. PC 16 at 3.
Dr. Schomer states that there is a trade-off between the complexity of the rules and the efficacy
of the regulations.
Id
. Dr. Schomer notes that the Illinois rules are more complex than in many
states, but as a result, Illinois’ rules are more useful and protective.
Id
. Dr. Schomer asserts that
because measurements made with simple, hand-held A-weighted instruments fail to address the
spectrum of octaves covered under Illinois regulations, the measurements give a misleading
picture of the noise emissions. PC 16 at 4. Dr. Schomer opines that to the extent the Board
allows such evidence to be admitted in a nuisance noise case, the entire decision making process
may be tainted by misleading information.
Id
.
 
Dr. Schomer, in his comment filed for Bridgeview, asserts that poor instruments may not
detect many valid nuisance noise instances. PC 19 at 2. The instruments that do not measure
individual octave bands may result in missing noise at a low frequency, according to Dr.
Schomer.
Id
. Dr. Schomer argues that the octave band nature of the Board’s rules is a positive
factor and should not be “squandered” by substituting A-weighted measurements of questionable
validity.
Id
.
 
 
Nuisance Noise Cases.
Bridgeview argues the Board should take the opportunity in
these rules to establish that in a nuisance complaint valid noise measurements must be used. PC
18 at 1. Bridgeview states that if noise measurements are taken in a nuisance case, the
measurements should be taken as directed in Part 910.
Id
. Bridgeview maintains that to do
otherwise is misleading to the complainant, prejudicial to the Board’s decisions, and
fundamentally unfair and costly to respondents.
Id
.
 
Bridgeview argues that admitting noise emissions measurements taken by a lay person
other than pursuant to the requirements of Part 910 is contrary to the Board’s responsibility for
admitting scientific evidence based on Daubert v. Merrell Dow Pharmaceuticals, Inc., 501 U.S.
579 (1993). PC 18 at 2. Bridgeview asserts that the Board recognizes the legal principal
articulated in Daubert but retreats froM the sound science approach in nuisance cases.
Id
.
Bridgeview opines that allowing “quick and dirty” sound measurements to be used in nuisance
cases, the Board is encouraging frivolous lawsuits.
Id
. Bridgeview further argues that the Board
appears to be shifting the burden of proof by requiring the respondent to expose problems with
the measurements. PC 18 at 3.
 
DISCUSSION
 
During the first-notice period, the comments and testimony received by the Board
reiterated issues raised prior to the Board proceeding to first notice in March 2005. The issues
are: (1) whether blasting operations by aggregate producers and surface coal mines should be
governed by rules adopted by the Board or should the Board defer to IDNR’s regulations; and (2)
whether the Board should require that noise measurements taken for presentation in a nuisance

 
9
noise enforcement case should be taken pursuant to 35 Ill. Adm. Code 910. The Board will
address these issues below.
 
Applicability of Noise Rules to Aggregate Producers and Surface Coal Mines
 
At first notice, the Board did make changes to the rule in response to IAAP’s comments.
After consideration of the testimony and comments from IAAP and IDNR during the first-notice
comment period, the Board is convinced that additional changes to the rule are warranted.
 
The testimony of IAAP and IDNR clearly demonstrates that IDNR has an extensive
regulatory program in place that regulates the noise from blasting at facilities operated by
aggregate producers and surface coal mines. Further, IDNR has an active staff that regularly
oversees blasting and monitoring of the blasting at sites in Illinois. IDNR also has stringent
enforcement tools for any violation of the regulations when blasting. Therefore, the Board finds
that the Board can appropriately defer the regulation of noise emissions from blasting at
aggregate and surface coal mines to IDNR. The Board will make changes to the rule under
Sections 901.107 and 901.109 to reflect that deference.
 
The Board notes that IAAP’s testimony indicates that IAAP only asks the Board to defer
to IDNR for blasting at the aggregate producers sites in Illinois. All other operations, such as
back up beepers, ingress and egress, and daily production noise emission should be subject to the
Board rules according to IAAP. In light of this, the Board limits the scope of the proposed
exemption to only to impulsive sound produced by explosive blasting activities, which are
regulated by IDNR in accordance with Section 6.5 and Section 3.13 of the Surface Coal Mining
Land Conservation and Reclamation Act (225 ILCS 715/6.5 and 3.13 (2004)).
 
Applicability of Part 910 to Nuisance Noise Enforcement Cases
 
The Board has long held in that noise measurements may be used to substantiate or refute
a nuisance noise claim.
See
Discovery South Group v. PCB, 275 Ill. App. 3d 547, 549, 656
N.E.2d 51, 59 (1st Dist. 1995); Charter Hall Home Owners Association v. Overland
Transportation System PCB 98-81 (Oct. 1, 1998); Pawlowski v. Benchwarmers Pub, PCB 99-82
(Apr. 6, 2000); Gladys Knox and David Knox v. Turris Coal Company and AEI Resources, Inc.,
PCB 00-140 (Jan. 9, 2003). In the Board’s first-notice opinion and order, the Board stated:
 
Section 910.104 clarifies that sound pressure level measurements are not required
to establish a violation of the Board’s nuisance noise standard at Section 900.102,
although such measurements may be used as corroborating evidence. In light of
this, the Board finds that compliance with the detailed sound measurement
procedures set forth in Part 951 or the proposed Part 910 are not required for
sound measurements used as corroborating evidence in a nuisance noise
proceeding. The Board will assign appropriate weight to sound measurement data
submitted in any nuisance noise complaint based on the information in the hearing
record and in accordance with the provisions of the Act. As noted in the first
first-notice opinion (Proposed New and Updated Rules for Measurement and
Numerical Sound Emissions Standards; Amendments to 35 Ill. Adm. Code 901

 
10
and 910, R03-9 (July 10, 1003)), the Board believes that this approach is
consistent with the Board’s precedence and case law concerning nuisance noise
complaints. The Board declines to make the changes suggested by IAAP.
Proposed New and Updated Rules for Measurement and Numerical Sound
Emissions Standards; Amendments to 35 Ill. Adm. Code 901 and 910, R03-9,
(Mar. 17, 2005).
 
The Board also discussed, at first notice, the request that noise measurements be
supervised by an individual who is certified. The Board stated:
 
The Board finds that the present regulatory structure, where the Board determines
the validity of sound data on a case-by-case basis in noise enforcement cases, is a
more prudent approach than prescribing vague qualification requirements. The
Board believes this is especially true absent a State approved licensing or
certification process. Proposed New and Updated Rules for Measurement and
Numerical Sound Emissions Standards; Amendments to 35 Ill. Adm. Code 901
and 910, R03-9, (Mar. 17, 2005).
 
The Board has carefully reviewed the arguments and concerns expressed by Bridgeview
and Dr. Schomer. However, the Board is unconvinced that a change to the rule is necessary.
First, as to the suggestion that the Board require compliance with Part 910 for measurement of
noise emissions in a nuisance noise enforcement, the Board does not believe that change is
necessary. If a complainant complies with the requirements of Part 910 when alleging a
violation, then such a violation would be of the numeric standards and not a nuisance violation.
The Board has long heard testimony in nuisance noise enforcement cases concerning the use of
noise measurements. The Board examines that testimony and the measurements in light of the
entirety of the evidence and renders a decision as to whether the noise unreasonablY interferes
with the enjoyment of life.
See e.g.
, Zivoli v. Somebody’s Bar and Restaurant, PCB 90-200
(May 21, 1992). Therefore, the Board declines to make a change to the rule.
 
regarding the qualifications of individual supervising the measurement of emissions, the
Board is not persuaded that requiring certification by the Institute is appropriate. The Board will
continue to review the noise emission measurements on a case-by-case basis and make
determination based on the evidence provided.
 
The Board finds that the extensive record in this proceeding supports proceeding to
second notice with these noise regulations. The Board further finds that the rules are technically
feasible and economically reasonable. Therefore the Board will proceed to second notice.
 
CONCLUSION
 
The Board today adopts for second notice regulations concerning measurement of and
standards for noise emissions in Illinois. The Board defers regulation of blasting operations at
aggregate and surface coal mines to IDNR, who has an extensive regulatory scheme in place.
The Board declines to alter the Board’s longstanding position on noise emission measurements
in nuisance noise enforcement cases and to require measurements be supervised by a certified

 
11
individual. The Board sends this proceeding to the Joint Committee on Administrative Review
for second notice consideration.
 
ORDER
 
The Board directs the Clerk to cause the filing of the following with the Joint Committee
on Administrative Review for second notice consideration.

Section 910.103 Definitions
 
The definitions contained in 35 Ill. Adm. Code 900.101 apply to this Part.
 
  
Section 910.104 Measurement Techniques for 35 Ill. Adm. Code 900
 
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. Adm. 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:
 
a) Site Selection
 
1) Measurements may be taken at one or more microphone positions within
the appropriate receiving land. Measurement instruments 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 35 Ill. Adm.
Code 901.
 
2) Measurement instruments 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) setback
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

 
74
 
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 that 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 must not be set up less than 50 feet (15.2 m) from any
reflective surface that may affect data. If measurements must be taken
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.) must 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 must be set at the chosen site. The tripod must 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 must be attached to the appropriate end of a 5-foot (1.5 m)
or longer cable and must be affixed to the top of the tripod. The other end
of the cable must be connected to the measuring instrument.
 
3) The angle of incidence of the microphone must be adjusted to yield the
flattest frequency response in accordance with the manufacturer’s
specifications.
 
4) The measuring instrument must 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) 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;
 

 
75
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
calibrated, remove the calibrator and attach a windscreen to the
microphone.
 
4) Adjust the microphone to the angle of incidence that will yield the
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 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 affected data block must be recorded. When using a tape
recorder, voice commentary concerning conditions will be recorded on the
cue track.
 

 
76
8) To minimize wind effects on the microphone, sound measurements 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 cannot be used for enforcement purposes.
 
11) Before removing the calibrator from the microphone, turn the calibrator
off. If the ambient sound 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 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) A magnetic tape recorder may be used to preserve the raw data.
Calibration signals 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. Voice commentary concerning local conditions and
affected data blocks must be recorded on the cue track. The original tape
recording must be preserved for subsequent evaluation. Laboratory
analyses may be performed on magnetic tape recorded field data. A

 
77
description of the laboratory instrumentation and procedures must be
recorded. Analyses used in the laboratory 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, 1/3
octave-band sound pressure levels must be obtained in determining
whether a noise source is in compliance with 35 Ill. Adm. Code 901.106.
 
2) For measurements of non-impulsive sound with no audible discrete tones,
octave-band sound pressure levels must be obtained in determining
whether a noise source is in compliance with 35 Ill. Adm. Code 901.102
and 901.103.
 
 
e) Correction Factors
 
If necessary, correction factors rounded to the nearest 1/2 decibel 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 must only be
used to make negative corrections (subtraction from the field data). In no case
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
 
a) The raw data collection procedures for the determination of equivalent continuous
sound pressure level (Leq) are described in this Section using as an example the
determination of a 1-hour Leq corrected for ambient. The following procedures
must be used:
 
1) Using small blocks:
 
A) The 1-hour interval is divided into many small blocks of time so
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 must remain fixed for any
measurement hour. The duration 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.
 

 
78
B) The collected data for each block represents a 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 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 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 time 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 in the
j

Where T is the block duration in seconds, NPLNS is the number of

an hour.
 
2) Continuous Data Collection:

 
79
 
A) The measuring instrument must be adjusted to continuously
measure sound pressure 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 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 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:

[Equation 5]
 
3) Minimum data collection requirements:
 
A) Initial Measurement Duration.
The property-line-noise-source
measurements 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
seconds (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 must be no less than 900
seconds.
 

 
80
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 must be appropriately modified and new measurements
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 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 must be corrected for long-term background
ambient sound. The subsection below describes methods to obtain
the long-term background ambient sound level in the jth frequency
band. The correction is dependent on the 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 raw 1-hour Leq and the
long-term background ambient sound is larger than
10 decibels, then the correction must 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, must 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 must be subtracted from the raw, 1-hour
property-line-noise-source Leqj
 
Table 1

4 2.3
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 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 must be measured for the purposes of this
Section during a 10-minute interval.
 
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: to divide the 10-
minute measurement into short blocks of data, or inhibit data collection
when short-term background transient sounds occur. The same method
must be used for gathering both the property-line-noise-source data and
the corresponding long-term background ambient data. The measurement
procedures for each method are given in subsections (b)(3), (b)(4) and
(b)(5) of this Section:
 
3) Using Small Blocks of Data
 
A) The 10-minute measurement of long-term background ambient
must be divided into short measurement blocks. The duration of
these blocks must remain constant during the entire measurement,
both when measuring the long-term background ambient and when
measuring the property-line-noise-source. The duration of this
measurement block in seconds, T, must divide exactly (without
remainder) into 600 and must be 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 must be discarded. The

 
82
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 time-averaged on
an energy basis over the NBA remaining measurement blocks to
obtain average long-term background ambient Leq per band.
Equation 1 (see subsection (a) (1) (E) of this Section) 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 must be adjusted according to
manufacturer’s instructions to continuously measure sound
pressure and accumulate (i.e. record) Leq. A switch 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).
 
B) The switches or buttons must be used to prevent short-term
background ambient sounds from corrupting the data.
 
C) Data collection 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 must be no less than 150
seconds. If TBA is less than 150 seconds, then the measurement of the
long-term background ambient 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 involve 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 is considered to be the most accurate
to what is considered to be the least accurate procedure.
 

 
83
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 to
24 hours before, or within one to 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 to 30 days before, or within
one to 30 days after measurement of the PLNS emissions. This
alternate long-term background ambient 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 30 to 90 days before, or
within 30 to 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 A through D in
Appendix A of this Part. 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
G.L. Bonvallet, “Levels and Spectra of Traffic, Industrial, and
Residential Area Noise,” Journal of the Acoustical Society of
America, 23 (4), pp 435-439, July 1951; and Dwight E. Bishop and

i) Category 1: Noisy Commercial and Industrial Areas. Very
heavy traffic conditions, such as in busy downtown
commercial areas, at intersections of mass transportation
and other vehicles, including the Chicago Transit Authority
trains, heavy motor trucks and other heavy traffic, and
street corners where motor buses and heavy trucks
accelerate.
 
ii) Category 2: Moderate Commercial and Industrial Areas,
and Noisy Residential Areas. Heavy traffic areas with
conditions similar to subsection (b)(6)(E)(i) of this Section
but with somewhat less traffic, routes of relatively heavy or
fast automobile traffic but where heavy truck traffic is not
extremely dense, and motor bus routes.
 
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 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 in subsection (b)(6)(E)(iii) of this
Section but, for this group, the background is either distant
traffic or is unidentifiable.
 
v) Category 5: Very Quiet, Sparse Suburban or Rural Areas.
These areas are similar to Category 4 subsection
(b)(6)(E)(iv) of this Section 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 35 Ill. Adm. Code 901.104 can be
made in two distinct and equally valid ways, namely the general method and the
controlled test method.
 

 
85
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 Sections 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 procedure is as follows:
 
A) Leq must be measured for the entire hour.
 
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 Sections
910.105 and 910.106. These requirements must be complied with to
determine an A-weighted, 1-hour, background-ambient-corrected 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 hour is the sum of the
sound exposures per hour from each of the separate individual
sources.
 

 
86
D) The reported SEL is obtained from the grand total sound exposure
(SE) per hour using the following:
 
SEL = 10 log (SE) + 94 [Equation 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) [Equation 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
measurements must be free of any short-term ambient sounds. If
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-weighted 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.
 

 
87
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.
