RE: Sprint Vision Cumulative Noise Study
Site #: BS23XC422 SBA Site #:MAO 1085-A
Site Name:SBA Tower
Address:300 Chestnut Street, North Andover,MA 01845
Dear Mr. Bakis:
This report is to demonstrate that the project proposed by Sprint is in compliance with the Town of
North Andover Zoning By-law requirement Section 8.9(4)(e)(iv) Environmental Standards, and
Section 8.9(5)(d)(vi) Noise Filing Requirements.
Section 8.9(4)(e)(iv)states:
1. Ground-mounted equipment for wireless service facilities shall not generate acoustic noise
in excess of 50dB at the security barrier.
In addition,Section 8.9(5)(d)(vi)(c) Requires the equipment to meet The Massachusetts
Department of Environmental Protection's (MA DEP) Noise Regulation,310 CMR 7.10. The
regulation considers a noise in violation if it:
I
1. Increases the broadband sound level by more than 10 dB(A) above ambient, or;
2. Produces a "pure tone" condition-when any octave band center frequency sound
pressure level exceeds the 2 adjacent center frequency sound pressure levels by 3 dB(A) or
more.

BACKGROUND NOISE SURVEY
i
HDG performed a background noise survey at the subject property on Saturday February 251h at
8:00 p.m, to Sunday February 26th 8:00 p.m. The logging sound level meter is in conformance with
the ANSI S1.4-1983 Type (S)2 & ANSI 51.43-1997 accuracy standards and measurements were
taken in accordance with ASTM E 1014-2008 Standard Guide for Measurement of Outdoor A-
Weighted Sound Levels. The location of the field measurement is shown on the site plan attached.
Table 1 shows the results using the Average Sound Level (Leq) in A-weighted decibels and L90
which is the sound level exceeded 90%of the time (commonly known as the quietist 10%of the
time period). L90 allows for filtering of short duration sound sources that produce a higher sound
level.

HDG also calculated the Day-Night Average Sound Level (Ldn). Ldn is the average equivalent
sound level over a 24 hour period,with a penalty added for noise during the nighttime hours of
10:00 P.M. to 07:00 a,m. During the nighttime period 10 dB is added to reflect the impact of the
noise.

EQUIPMENT NOISE EVALUATION
I am well-versed with the technical specifications, published acoustical noise levels, and actual
operating conditions of the Alcatel-Lucent 9928 Distributed Base Station (DBS) utilized by Sprint.
During normal operating conditions the fresh air cooling fans built into the DBS will create the
maximum acoustical noise level of this equipment. in addition,Sprint proposes to remove an
existing Lucent Flexent Modcell 2.0 cabinet. Table 2 provides the maximum sound pressure level of
the cabinet to be removed and the proposed cabinet.

AlcateYLucent9928 Pro used 65 '
This sound is approximately equivalent to a standard household vacuum cleaner at 10'. All other
proposed equipment does not produce noise during operation.
CUMULATIVE NOISE RESULTS
Utilizing the free field formula (20 log R) for further attenuation for spherical spreading we show the
calculated noise levels in Table 3.

`Note: Sprint is proposing to replace the existing Flexent Modcell cabinet with the new 9928
DBS with a similar acoustic noise level of 65 dB(A). Therefore it is anticipated that there will
be no change in the background noise levels at the fence and property lines.
CONCLUSION
The Town of North Andover defines a noise in violation if it exceeds 50 dB at the security barrier.
The Average Day-Night noise level (Ldn) is estimated to be 58.3 dB(A). However,Sprint proposes to
remove an existing Lucent Flexent Modcell 2.0 cabinet which produces a similar sound pressure
level as the proposed Alcatel-Lucent 9928. As a result, there will be no perceptible change in noise
at the security fence or the properly line.
The MA DEP Noise Regulation,310 CMR 7.10 defines unnecessary, excessive, or offensive noise as a
noise level which exceeds the ambient noise level by 10 dB(A),and 3 dB(A) if a tonal component
exists. There is no calculated increase in the noise level at the south property line. Therefore,
during normal operating conditions, it is my professional opinion that the predicted maximum
acoustical noise levels from the Sprint equipment will be in conformance with the MA DEP noise
regulation.

Memorandum for Record
Introduction
The Acoustical Noise Suppression test was performed on an outdoor version Flexent Modcell on January
24,2000 at the Noise Unlimited Inc.test laboratory located in Annandale,NJ.This test was conducted to
verify compliance of the outdoor version of the Flexent Modcell to the Bellcore acoustic noise suppression
requirement specified in section 3.28 R3-157 of GR-487-CORE(Generic Requirements for Electronic
Equipment Cabinets)see Noise Unlimited Test Report No.9065.1.Marvin Lowman of Noise Unlimited
Inc.conducted the testing.G.Mikus and J.Stofanek of Lucent Technologies were present during the
testing.
Bellcore Requirement Description
Cabinets,equipped with telecommunications equipment and associated cooling falls,shall suppress
acoustical noise to a level of 65dBA at a distance of 1.5nh(5ft)from the cabinet with the doors closed
during times of maximum noise generation within the cabinet.
Test Procedure:
• Sound measurements shall be made in a room or enclosure that duplicates as much as possible the
acoustic properties of a network facility and the actual service environment.
• The sound level shall be measured by a sound meter meeting ANSI 1.4,and set to the A-
weighting scale and the slow meter response setting.
• Measurements shall be made in accordance with ANSI St.18.
• Cabinet doors shall be closed.
• Sound levels produced shall be measured at 5ft from the cabinet surfaces in all horizontal
directions at a height of 3ft from the cabinet mounting surface.
Test Setup
Lucent Technologies
Proprietary-Use pursuant to Company Instructions
e) Environmental Standards
i) Wireless services facilities shall not be located in wetland resource areas. Locating of
wireless facilities in wetland buffer areas shall he avoided whenever possible and
disturbance to wetland buffer areas shall be minimized. All Conservation Commission
