As used in this chapter, the following terms
shall have the meanings indicated:
All-encompassing noise associated with a given environment.
The band-pressure level of a sound for a specified frequency
band is the sound-pressure level for the sound contained within the
restricted band. The reference pressure must be specified.
A unit of level when the base of a logarithm is 10 and is
restricted to levels of quantities proportional to power.
The complete sequence of values of a periodic quantity that
occur during a period.
One-tenth of a bel and is a unit of level when the base of
the logarithm is the tenth root of 10 and the quantities concerned
are proportional to power.
The noise level-metering device is using the A-weighted network
to duplicate how the human ear hears the noise.
The duration of a transient noise is the period of time the
noise from a linear moving device or vehicle is distinguished from
the ambient noise.
These terms may be used interchangeably and are known as
a unit which may be used for work or recreational purposes which creates
noise and disturbs, as provided herein, whether it is hand-driven
or operated or is mechanically, electrically or electronically powered
or operated.
A unit which may be used for recreational purposes which
creates noise and disturbs, as provided herein, whether it is hand-driven
or operated or is mechanically, electrically or electronically powered
or operated, and is not specified, built or mufflered for street or
highway traffic (i.e., moto-dirt bike, minibike, motocross bike).
The frequency of a function periodic in time is the reciprocal
of the primitive period. The unit is the cycle per unit time and must
be specified.
Any linear moving device or vehicle shall be considered as
one that can be maneuvered or moves about, (i.e., auto, boat, helicopter).
A unit of pressure commonly used in acoustics and is equal
to one dyne per square centimeter.
Any increase in the ambient noise, heard and measured in
this article or otherwise determined and confirmed. "Noise" is divided
into the following categories:
TRANSIENT NOISEAny noise having a duration of six seconds up to one minute shall be considered a "transient noise."
STEADY NOISEAny noise caused by any mechanical device (defined in § 230-1E) that continues in excess of one minute shall be considered a steady noise, (i.e. air conditioner, compressor, device or vehicle with motor running while parked or standing).
IMPACT NOISEAny noise caused by actions involving pounding, chipping, hammering or explosive-discharge noise from a firearm [see § 230-1D(2)(b)].
Includes the singular and plural and shall also mean and
include any person, firm, corporation, association, club, partnership,
society, union or any other form of association or organization.
A device for measuring the band-pressure level or pressure
spectrum level of a sound as a function of frequency.
An instrument (including a microphone, an amplifier, an output
meter and frequency weighing networks) for the measurement of noise
and sound levels in the manner provided by this article.
The sound-pressure level, in decibels, of a sound is 20 times
the logarithm to the base 10 of the ratio of the pressure of this
sound to the reference pressure, which reference pressure must be
explicitly stated.
A function of time and is a description of its resolution
into components, each of different frequency, and is also used to
signify continuous range of components usually wide in extent within
which waves have some specified characteristics such as "audio-frequency
spectrum," and is also applied to functions of variables other than
time.
A device to monitor the wind velocity up to the equivalent
of 12 miles per hour.
[Amended 4-2-2001 by L.L. No. 2-2001]
Except as otherwise provided in this chapter,
no person shall create or cause to be emitted any noise within the
Town of Grand Island exceeding the dB(A) noise limitation as set forth
herein, as measured on a sound-level meter using the A-weighted scale
with slow response.

In the Town of Grand Island and the New York State
Thruway from 7:00 a.m. to 7:00 p.m., the limits herein set forth shall
apply to transient noises having a duration in excess of 12 seconds,
noise regulations of the New York State Department of Transportation
and Environmental Protection Agency notwithstanding.

In the Town of Grand Island, from 7:00 p.m. to 7:00
a.m., the same limits shall apply to transient noises having a duration
in excess of six seconds, except on the New York State Thruway, where
the noise regulations noted above apply.

Noise measurements and limits shall conform
to the following practices:
A.Â
Noise shall be measured at an altitude between 500
feet and 700 feet above sea level with wind velocity less than 12
miles per hour and microphone wind screen in place using a sound-level
meter conforming to ANSI Type II Standards and set at slow meter reading
response.
B.Â
Measurement of transient noise emanating from any
linear moving device or vehicle including, but not limited to, motor
vehicles, shall be made at or adjusted to a distance of 50 feet from
the longitudinal center line of the device or vehicle with the microphone
three to five feet above the ground.
C.Â
Steady noise, including manual creative work noise
and repair work noise, shall be measured at three feet from the major
surface (i.e., floor, walls) of residences, buildings or structures
used primarily for sleeping purposes by people with the microphone
three feet to five feet above the ground.
