Subject: 
SuperStar Express Car Wash @ 5810 West Thunderbird Road – Noise Assessment – City of 
Glendale, AZ 
 
Dear Mr. Amirrezvani: 
 
MD Acoustics, LLC (MD) has completed a noise assessment for the proposed SuperStar Express Car Wash 
located at 5810 West Thunderbird Road, in Glendale AZ. This assessment reviews the projected car wash 
operational noise levels and compares to the City’s noise ordinance. The project proposes an 
approximately 116-foot car wash tunnel with 28 covered vacuum bays.

Assessment Overview 
This assessment evaluates the projections operational noise and compares to the City’s noise ordinance 
for informational purposes. The project location map is located in Exhibit A. The site plan utilized for the 
project is indicated in Exhibit B. It should be noted that the nearest residences are located 700-feet to the 
north. A glossary of Acoustical Terms is located in Appendix A.  
 
2.0 
Acoustical Requirements 
The City of Glendale outlines their noise regulations and standards within the Code of Ordinances from 
the Municipal Code. Chapter 25, Section 25-64 outlines the noise standards and is as follows:  
 
a) It shall be unlawful for any person to make or continue, or cause or permit to be made or 
continued, any excessive, unnecessary, or offensive noise that disturbs the peace and quiet or that 
causes discomfort or annoyance to two or more independent witnesses who are not related.  
b) This article is intended to reduce the amount of return visits by law enforcement. Subsequent 
visits by law enforcement will be cause for abatement of such disturbance and will require a 
mandatory restitution assessment for the law enforcement subsequent response services as a 
term of the sentencing.

SP’s software utilizes algorithms (based on the inverse square law and reference equipment noise level 
data) to calculate noise level projections. The software allows the user to input specific noise sources, 
spectral content, sound barriers, building placement, topography, and sensitive receptor locations. 
 
The future worst-case noise level projections were modeled using referenced sound level data for the 
various stationary on-site sources (vacuums, vacuum turbine motors and car wash blowers at the exit). 
The SP model assumes a total of 28 vacuums and the dryer system are operating simultaneously (worst-
case scenario), when the noise will in reality be intermittent and lower in noise level.  
 
In addition, the modeling takes into account existing property line walls, commercial buildings, and 
equipment enclosures proposed for the vacuum turbine. The reference vacuum equipment sound level 
data is provided in Appendix B. 
 
All other noise producing equipment (e.g., compressors, pumps) will be housed within mechanical 
equipment rooms. 
 
The following outlines the project design features: 
 
1. The project will incorporate approximately twelve (12) 15-HP Sonny Blowers within the tunnel. 
 
2. The project proposes to house the vacuum turbine motors inside the attached fully enclosed 
equipment room. 
 
SoundPlan input and output values are provided in Appendix C. 
 
4.0 
Noise Level Projections and Recommendations 
The worst-case stationary noise was modeled using SoundPLAN acoustical modeling software. Worst-case 
assumes the blowers, vacuums and equipment are always operational when in reality the noise will be 
intermittent and cycle on/off depending on the customer usage.  
 
The modeling takes into account the proposed tunnel and equipment design, enclosure for the vacuum 
turbines.  Project operations are anticipated to occur within the City’s allowable daytime standards.  
 
A total of four (4) receptors (R1 – R4) were modeled to evaluate the proposed project’s operational 
impact. R1 – R4 represents the noise level to the nearest commercial uses. 
 
All yellow dots represent either a property line or a sensitive receptor such as an outdoor sensitive area 
(e.g. courtyard, patio, backyard, etc). 
 
Exhibit C illustrates the noise level projections associated with the car wash noise operations when all 
equipment is fully active (even though the noise will be intermittent). The noise projections demonstrate 
that the operational noise level to the nearest commercial uses will range between 55 to 62 dBA. The 
noise level at the residences to the north will be 36 dBA.

It is anticipated that within a 200 to 300 ft radius the car wash noise levels will be audible. Beyond said 
radius, local traffic noise becomes the dominate noise source and the car wash noise gets masked from 
local traffic. Residences are located 700 feet north of the site are outside the confluence of the car wash 
noise. In addition, existing retail structures further block the line of sight of the car wash to the residences. 
 
It should be noted that the City of Glendale does not have a specific not-to-exceed noise limit. Therefore, 
this study compares the predicted car wash noise level to the estimated baseline traffic noise condition.  
 
It is estimated that there are 15,000 to 20,000 average daily traffic volumes (ADTs) along Thunderbird 
Blvd. Based on the ADTs, vehicle speed, vehicle mix, the calculated noise level at 50-ft from the centerline 
of the roadway would be 68 dBA (see Appendix D). When extrapolating the data out to the existing 
commercial buildings north of the project site the anticipated baseline noise level is 55 dBA. The 
anticipated traffic noise level to the residences to the north (approximately 900 feet from the centerline) 
would be 48 to 52dBA. 
 
 When comparing the predicted car wash noise levels to the estimated baseline noise levels at the 
residences to the north, it is anticipated that the noise level will be 36 dBA which is more than 10 dBA 
quieter than the existing condition. The noise level will not increase at the residences to the north.

Conclusions 
MD is pleased to provide this noise assessment for the SuperStar Express Car Wash project. Project 
operations are anticipated to comply with the City’s noise ordinance. If you have any questions regarding 
this analysis, please call our office at (602) 774-1950.

Operational Noise Levels

Appendix A 
Glossary of Acoustical Terms

Glossary of Terms 
 
A-Weighted Sound Level: The sound pressure level in decibels as measured on a sound level 
meter using the A-weighted filter network.  The A-weighting filter de-emphasizes the very low 
and very high frequency components of the sound in a manner similar to the response of the 
human ear.  A numerical method of rating human judgment of loudness. 
 
Ambient Noise Level: The composite of noise from all sources, near and far.  In this context, the 
ambient noise level constitutes the normal or existing level of environmental noise at a given 
location. 
 
Community Noise Equivalent Level (CNEL): The average equivalent A-weighted sound level 
during a 24-hour day, obtained after addition of five (5) decibels to sound levels in the evening 
from 7:00 to 10:00 PM and after addition of ten (10) decibels to sound levels in the night before 
7:00 AM and after 10:00 PM. 
 
Day-Night-Level (DNL or LDN): The average equivalent A-weighted sound level during a 24-hour 
day, obtained after addition of ten (10) decibels to sound levels in the night before 7:00 AM and 
after 10:00 PM. 
 
Decibel (dB): A unit for measuring the amplitude of a sound, equal to 20 times the logarithm to 
the base 10 of the ratio of the pressure of the sound measured to the reference pressure, which 
is 20 micro-pascals. 
 
dB(A):  A-weighted sound level (see definition above). 
 
Equivalent Sound Level (LEQ): The sound level corresponding to a steady noise level over a given 
sample period with the same amount of acoustic energy as the actual time varying noise level.  
The energy average noise level during the sample period. 
 
Habitable Room: Any room meeting the requirements of the Uniform Building Code or other 
applicable regulations which is intended to be used for sleeping, living, cooking or dining 
purposes, excluding such enclosed spaces as closets, pantries, bath or toilet rooms, service 
rooms, connecting corridors, laundries, unfinished attics, foyers, storage spaces, cellars, utility 
rooms and similar spaces.  
 
L(n): The A-weighted sound level exceeded during a certain percentage of the sample time.  For 
example, L10 in the sound level exceeded 10 percent of the sample time.  Similarly L50, L90 and 
L99, etc.

Noise: Any unwanted sound or sound which is undesirable because it interferes with speech and 
hearing, or is intense enough to damage hearing, or is otherwise annoying.  The State Noise 
Control Act defines noise as "...excessive undesirable sound...". 
 
Noise Criteria (NC) Method: This metric plots octave band sound levels against a family of 
reference curves, with the number rating equal to the highest tangent line value as demonstrated 
in Figure 1.  
 
Percent Noise Levels: See L(n). 
 
Room Criterion (RC) Method: When sound quality 
in the space is important, the RC metric provides a 
diagnostic tool to quantify both the speech 
interference level and spectral imbalance. 
 
Sound Level (Noise Level): The weighted sound 
pressure level obtained by use of a sound level 
meter having a standard frequency-filter for 
attenuating part of the sound spectrum. 
 
Sound Level Meter: An instrument, including a 
microphone, an amplifier, an output meter, and 
frequency 
weighting 
networks 
for 
the 
measurement and determination of noise and 
sound levels. 
 
Sound Transmission Class (STC):  To quantify STC, a Transmission Loss (TL) measurement is 
performed in a laboratory over a range of 16 third-octave bands between 125 – 4,000 Hertz (Hz). 
The average human voice creates sound within the 125 – 4,000 Hz 1/3rd octave bands. 
STC is a single-number rating given to a particular material or assembly. The STC rating measures 
the ability of a material or an assembly to resist airborne sound transfer over the specified 
frequencies (see ASTM International Classification E413 and E90). In general, a higher STC rating 
corresponds with a greater reduction of noise transmitting through a partition. 
STC is highly dependent on the construction of the partition. The STC of a partition can be 
increased by: adding mass, increasing or adding air space, adding absorptive materials within the 
assembly. The STC rating does not assess low frequency sound transfer (e.g. sounds less than 125 
Hz). Special consideration must be given to spaces where the noise transfer concern has lower 
frequencies than speech, such as mechanical equipment and or/or music. The STC rating is a lab 
test that does not take into consideration weak points, penetrations, or flanking paths.  
Even with a high STC rating, any penetration, air-gap, or “flanking path can seriously degrade the 
isolation quality of a wall. Flanking paths are the means for sound to transfer from one space to 
FIGURE 1: Sample NC Curves and 
Sample Spectrum Levels

another other than through the wall. Sound can flank over, under, or around a wall. Sound can 
also travel through common ductwork, plumbing or corridors. Noise will travel between spaces at 
the weakest points. Typically, there is no reason to spend money or effort to improve the walls 
until all weak points are controlled first. 
 
Outdoor Living Area: Outdoor spaces that are associated with residential land uses typically used 
for passive recreational activities or other noise-sensitive uses.  Such spaces include patio areas, 
barbecue areas, jacuzzi areas, etc. associated with residential uses; outdoor patient recovery or 
resting areas associated with hospitals, convalescent hospitals, or rest homes; outdoor areas 
associated with places of worship which have a significant role in services or other noise-sensitive 
activities; and outdoor school facilities routinely used for educational purposes which may be 
adversely impacted by noise.  Outdoor areas usually not included in this definition are:  front yard 
areas, driveways, greenbelts, maintenance areas and storage areas associated with residential 
land uses; exterior areas at hospitals that are not used for patient activities; outdoor areas 
associated with places of worship and principally used for short-term social gatherings; and, 
outdoor areas associated with school facilities that are not typically associated with educational 
uses prone to adverse noise impacts (for example, school play yard areas). 
 
Percent Noise Levels: See L(n). 
 
Sound Level (Noise Level): The weighted sound pressure level obtained by use of a sound level 
meter having a standard frequency-filter for attenuating part of the sound spectrum. 
 
Sound Level Meter: An instrument, including a microphone, an amplifier, an output meter, and 
frequency weighting networks for the measurement and determination of noise and sound 
levels. 
 
Single Event Noise Exposure Level (SENEL): The dB(A) level which, if it lasted for one second, 
would produce the same A-weighted sound energy as the actual event.
