As used in this chapter, the following terms shall
have the meanings indicated:
AMBIENT NOISE
The all-encompassing noise associated with a given environment,
being usually a composite of sounds from many sources.
A-WEIGHTED SOUND LEVEL [dB(A)]
The sound pressure level in decibels as measured on a sound-level
meter using the A-weighting network slow response. The level so read
is designated dB(A).
EMERGENCY
Any occurrence or set of circumstances involving actual or
imminent physical trauma or property damage which demands immediate
action.
IMPULSIVE SOUND
A sound characterized by brief excursions of peak sound pressure
which significantly exceed the ambient sound.
PEAK SOUND PRESSURE LEVEL
The maximum absolute value of the instantaneous sound pressure
level during a specified time interval.
SOUND-LEVEL METER
An instrument, including a microphone, an amplifier, an output
meter and frequency-weighting networks, for the measure of sound levels.
SOUND PRESSURE LEVEL
The weighted sound pressure level in decibels obtained by
the use of a sound-level meter and frequency-weighting network, such
as A, B or C. If the frequency weighting employed is not indicated,
the A-weighting slow response shall apply.
SOUND REPRODUCTION DEVICE
Any device that is designed to be used or is actually used
for the production or reproduction of sound, including but not limited
to any musical instrument, radio, television, tape recorder, phonograph,
loudspeaker, public-address system or any other sound-amplifying device.
SOUND SOURCE SITE
A parcel of land, or a tract of land consisting of two or
more parcels, which includes all contiguous land and water areas under
the ownership or control of a person in or upon which one or more
sound sources are located. The "sound source site" includes all individual
sound sources that are located on such site, whether stationary, movable
or mobile. A sound source site is created by the installation of one
or more sound sources thereon.
UNREASONABLE NOISE
Any excessive or unusually loud sound or any sound which
either annoys, disturbs, injures or endangers the comfort, repose,
health, 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)
The intensity of the noise.
(3)
Whether the nature of the noise is usual or
unusual.
(4)
Whether the origin of the noise is usual or
unusual.
(5)
The volume and intensity of the background noise,
if any.
(6)
The proximity of the noise to residential sleeping
facilities.
(7)
The nature and the zoning district of the areas
within which the noise emanates.
(8)
The time of the day or night the noise occurs.
(9)
The time duration of the noise.
(10)
Whether the sound source is temporary.
(11)
Whether the noise is continuous or impulsive.
