Subject: 
Ultra Clean Express Car Wash at 83rd and Glendale Ave – Noise Impact Study – 
 
City of Glendale, AZ 
 
Dear Ms. Rudolph: 
 
MD Acoustics, LLC (MD) has completed a noise assessment for the proposed Ultra Clean Express Car Wash 
located at the northeast corner of 83rd Avenue and West Glendale Avenue in the City of Glendale, AZ. This 
assessment reviews the projected car wash operational noise levels and compares them to the City’s noise 
ordinance. The project proposes an approximately 124-foot car wash tunnel with 30 covered vacuum 
bays.

Assessment Overview 
 
This assessment evaluates the projections of operational noise and compares them 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. The land uses directly surrounding the project site are 
residential to the north, east, and northwest, commercial to the west and southwest, and undeveloped to 
the south. Other residences near the project site are located approximately 340 feet to the southeast and 
800 feet to the south. There are drive-throughs at the Walgreens and Mcdonald’s to the southwest. West 
Glendale Avenue is to the south, and 83rd Avenue is to the west.

Local Acoustical Requirements 
 
The City of Glendale does not have a specific not to exceed noise limit as it relates to stationary noise 
sources. However, Section 25-64 of the City of Glendale Municipal Code provides further information as it 
relates to the City’s noise ordinance and is as follows: 
 
Sec. 25-64. Excessive, unnecessary, or offensive noise prohibited. 
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.  
 
In an effort to provide a quantified analysis of the noise, this review assesses the project’s operational 
noise levels at adjacent sensitive uses.

Study Method and Procedure
SoundPLAN Acoustic Model
SoundPLAN 
 
(SP) 
 
acoustical 
 
modeling 
 
software 
 
was 
 
utilized 
 
to 
 
model 
 
future 
 
worst-case 
 
stationary 
 
noise
impacts to the adjacent land uses. SP is capable of evaluating multiple stationary noise source impacts at
various 
 
receiver 
 
locations. 
 
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 tunnel is approximately 124 feet long with a 11-foot-tall by 11-foot-wide exit and entrance opening.
The blowers (a 9 Sonny’s blower system with the silencer package installed or equivalent) were modeled
at 10 feet high as point sources. The blowers will be located approximately 5 to 10 feet inside the exit of
the tunnel. The reference equipment sound level data is provided in Appendix B.
The SP model assumes a total of 30 vacuums and the dryer system are operating simultaneously (worst-
case 
 
scenario) 
 
when 
 
in 
 
actuality, 
 
the 
 
noise 
 
will 
 
be 
 
intermittent 
 
and 
 
lower 
 
in 
 
noise 
 
level. 
 
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.

Findings and Recommendations
Existing Exterior Noise
Two (2) 15-minute ambient noise measurements were conducted at the project site on May 25th, 2023.
The sound level meter measured the Leq, Lmin, Lmax, and other statistical data (e.g., L2, L8…). The noise
measurements were taken to determine the existing ambient noise levels. Noise data indicates that traffic
along West Glendale 
 
Avenue and 83rd
 
Avenue is the 
 
primary source 
 
of 
 
noise 
 
impacting the 
 
site and 
 
the
adjacent 
 
uses. 
 
This 
 
assessment 
 
utilizes 
 
the 
 
ambient 
 
noise 
 
data 
 
as 
 
a 
 
basis 
 
and 
 
compares 
 
project
operational levels to said data.
The results of the short-term noise data are presented in Table 1.

Noise data indicates the ambient noise level is 54 to 67 dBA Leq near the project site and surrounding 
area. Additional field notes and photographs are provided in Appendix A. NM1 represents the nearby 
residential properties, and NM2 represents the nearby commercial properties. 
 
For this evaluation, MD has compared the project’s projected noise levels to the existing ambient level.  
 
Future Exterior Noise 
Sensitive receptors affected by the project operational noise include existing residences to the north, 
south, and east and commercial drive-throughs to the southwest. A total of five (5) receptors were 
modeled to accurately evaluate the future operational noise levels at the sensitive receptors. A yellow dot 
denotes a receptor. All yellow dots represent a property line or a noise-sensitive receptor, such as a drive-
thru window. Receptors 1 through 4 represent existing residential uses, and receptor 5 represents the 
southwest drive-throughs. 
 
Table 2 presents the measured ambient noise level, the project’s noise level, and the combined project 
plus ambient noise level condition.

Notes:
1. Receptors 1 -4 represent residential uses. Receptor 5 represents the southwest drive-throughs.
2. See Appendix A for the ambient noise measurement.
3. See Exhibit F for the operational noise level projections at said receptors.
 
Exhibit C shows the future noise level projections and contours based on the proposed project design. The 
model indicates that the project-only noise level will be 48 to 56 dBA at the existing residential receptors 
and 62 dBA Leq at the nearby drive-throughs. The project will increase the existing ambient noise level by 
1 to 4 dB at the sensitive receptors. The noise code does not specify a quantitative noise standard but 
instead prohibits unreasonably loud and disturbing noise. Table 3 provides the characteristics associated 
with changes in noise levels.

It takes a change of 3 dB for the human ear to perceive a difference and a change of 5 dB to perceive a 
clearly noticeable difference. Therefore, the change in noise level would be “Not Perceptible” to “Just 
Perceptible” at the sensitive receptors. The impact is, therefore, less than significant.

Caution: You must shut off all power to the conveyor and lock out the Motor Control Center 
before starting this install. 
1. Shut off all power to the conveyor, blowers and lock out the Motor Control Center. 
2. Insert the silencer over the venturi.  For the gator silencer option, align notches to the 
gator actuator bracket (as pictured above). 
3. Using the existing holes on the Silencer housing, affix the silencer to the gator housing 
using (8) of the provided self-tapping screws (# 10013134). 
4. Avoid over-torqueing the self-tapping screws to prevent stripping the plastic housing.

* Refers to the logarithmic average of all measurements. This measurement represents an average of the multiple vacuum positions.
Clear sky, measurements were performed within 1.5ft of source. Measurements were performed while the vacuum was 
positiioned at three (3) different positions. Holstered, unholstered and inside a car. This data is utilized for acoustic 
modeling purposes and represents an average sound level at a vacuum station.
