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:
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.
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."
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).
A public disaster or an exposure of any person or property to imminent danger.
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.
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.
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.
Any area designated pursuant to this section for the purpose of ensuring exceptional quiet.
The weighted sound pressure level obtained by the use of a sound level meter and frequency weighting network.
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.
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.
Any device, fixed or movable, which is located or used on geographically defined real property other than a public right-of-way.
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:
Whether the nature and origin of the noise is usual or unusual.
The volume and intensity of the background noise, if any.
The nature and zoning district of the areas within which the noise emanates.
The time of the day or night the noise occurs.
