Definitions. The following words, terms and phrases, when used in
this section, shall have the meanings ascribed to them in this section,
except where the context clearly indicates a different meaning:
AMBIENT NOISE LEVEL
The sound pressure level of the all-encompassing noise associated
with a given environment, being usually a composite of sounds from
many sources. Man-made sounds shall be included in the ambient noise
level if they originate from permanent continuously operating equipment
necessary for the facility or residential operation. An example of
one such sound is air conditioning or fan units.
C-WEIGHTED SOUND PRESSURE LEVEL
The sound pressure level in decibels as measured on a sound
level meter, using the C-weighting network, by a trained operator.
The level so read is designated "dB(C)" or "dBC."
DECIBEL (DB)
The practical unit of measurement for sound pressure level.
The number of decibels of a measured sound is equal to 20 times the
logarithm to the base 10 of the ratio of the sound pressure of the
measured sound to the sound pressure of a standard sound (20 micropascals).
EMERGENCY
A public disaster or an exposure of any person or property
to imminent danger.
EMERGENCY SIGNAL DEVICE
Any gong, siren, whistle, air horn or similar device, the
use of which on emergency vehicles is permitted by Subdivision 26
of § 375 of the New York State Vehicle and Traffic Law.
EQUIVALENT CONTINUOUS SOUND PRESSURE LEVEL (LEQ)
A calculated sound pressure (noise) level of an imaginary
continuous constant amplitude signal, within a given time interval,
that would produce the same energy as the fluctuating sound level
that is being measured.
NOISE and NOISE DISTURBANCE
For the purpose of this section, shall mean any increase
in the ambient noise level or any sound which exceeds the sound pressure
levels, set forth in this section and has been generated by electronic
or amplified means.
NOISE-SENSITIVE ZONE
Any area designated pursuant to this section for the purpose
of ensuring exceptional quiet.
SOUND LEVEL
The weighted sound pressure level obtained by the use of
a sound level meter and frequency weighting network.
SOUND LEVEL METER
An instrument, which includes a microphone, amplifier, RMS
detector, integrator, output meter and frequency weighting networks,
for the measurement of noise and sound pressure levels which conforms
to the American National Standards Institute (ANSI) Type I or Type
II standards.
SOUND PRESSURE LEVEL
In decibels, 20 times the logarithm to the base 10 of the
ratio of the pressure of the sound to the reference pressure, which
reference pressure of 20 micropascals.
STATIONARY NOISE SOURCE
Any device, fixed or movable, which is located or used on
geographically defined real property other than a public right-of-way.
UNREASONABLE NOISE
Any excessive or unusually loud electronically generated
and/or amplified sound which either disturbs, injures or endangers
the peace or safety of a reasonable person of normal sensitivities
or which causes injury to animal life or damage to property or business.
Standards to be considered in determining whether unreasonable noise
exists in a given situation include but are not limited to the following:
(2)
Whether the nature and origin of the noise is usual or unusual.
(3)
The volume and intensity of the background noise, if any.
(4)
The nature and zoning district of the areas within which the
noise emanates.
(5)
The time of the day or night the noise occurs.
