As used in this chapter, the following terms shall have the meanings indicated:
AMBIENT NOISE
All-encompassing noise associated with a given environment.
BAND-PRESSURE LEVEL
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.
BEL
A unit of level when the base of a logarithm is 10 and is restricted to levels of quantities proportional to power.
CYCLE
The complete sequence of values of a periodic quantity that occur during a period.
DECIBEL
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.
DECIBEL A SCALE or dB(A)
The noise level-metering device is using the A-weighted network to duplicate how the human ear hears the noise.
DURATION
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.
EQUIPMENT, DEVICE or VEHICLE
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.
FIELD VEHICLE
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).
FREQUENCY
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.
LINEAR
Any linear moving device or vehicle shall be considered as one that can be maneuvered or moves about, (i.e., auto, boat, helicopter).
MICROBARS
A unit of pressure commonly used in acoustics and is equal to one dyne per square centimeter.
NOISE
Any increase in the ambient noise, heard and measured in this article or otherwise determined and confirmed. "Noise" is divided into the following categories:
A. 
Any noise having a duration of six seconds up to one minute shall be considered a "transient noise."
B. 
Any 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).
C. 
Any noise caused by actions involving pounding, chipping, hammering or explosive-discharge noise from a firearm [see § 230-1D(2)(b)].
PERSON
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.
SOUND ANALYZER
A device for measuring the band-pressure level or pressure spectrum level of a sound as a function of frequency.
SOUND-LEVEL METER
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.
SOUND-PRESSURE LEVEL
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.
SPECTRUM
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.
WIND MEASURING GAUGE
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.
A. 
Table 1.
Limiting Levels for Transient Noise
Daytime
(7:00 a.m. to 7:00 p.m.)
Nighttime
(7:00 p.m. to 7:00 a.m.)
85 dB(A)
85 dB(A)
(1) 
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.
(2) 
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.
B. 
Table 2.
Limiting Levels for Steady Noise
Daytime
(9:00 a.m. to 11:00 p.m.)
Nighttime
(11:00 p.m. to 9:00 a.m.)
65 dB(A)
50 dB(A)
Noise measurements and limits shall conform to the following practices:
A. 
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. 
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. 
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.
