A-WEIGHTED SOUND PRESSURE LEVEL
The sound pressure level as measured in decibels on a sound level meter using the A-weighting network. The level so read shall be designated dB(A) or dBA.
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, and/or the A-weighted sound pressure level exceeded 90% of the time/L90, based on a one-hour period.
CONTINUOUS NOISE
A steady, fluctuating or impact noise which exists, essentially without interruptions, for a period of one hour or more.
CYCLICALLY VARYING NOISE
A steady, fluctuating or impulsive noise which may or may not contain a pure tone, which varies in sound pressure level such that the same level is obtained repetitively at reasonably uniform intervals of time.
DECIBEL
A logarithmic (dimensionless) unit of measure often used in describing the amplitude of sound. Decibel is denoted as "dB."
DEPARTMENT
Any municipal agency.
DEVICE
Any mechanism which is intended to produce or which actually amplifies or produces noise when operated or handled.
EMERGENCY VEHICLE
A motor vehicle used in response to a public calamity or to protect persons or property from imminent danger.
EMERGENCY WORK
Work made necessary to restore property to a safe condition following a public calamity, work to restore public utilities or work required to protect persons or property from an imminent exposure to danger.
FLUCTUATING NOISE
The sound pressure level of a "fluctuating noise" varies more than six dB(A) during the period of observation when measured with the slow meter characteristic of a sound level meter and does not equal the previously existing ambient noise level more than once during the period of observation.
MOTOR VEHICLE
Any vehicle which is propelled or drawn by mechanical equipment, such as but not limited to passenger cars, trucks, truck-trailers, semitrailers, campers, motorcycles, minibikes, go-carts, snowmobiles, amphibious craft on land, dune buggies or racing vehicles.
MUFFLER
Any apparatus consisting of baffles, chambers of acoustical absorbing materials, whose primary purpose is to transmit liquids or gases while causing a reduction in sound emission at one end.
NOISE
Any sound which is unwanted or which causes or tends to cause an adverse psychological effect on human beings.
NOISE BAFFLE
A physical barrier for deflecting, checking or otherwise regulating the flow of noise.
NOISE DISTURBANCE
Any sound which annoys, disturbs or perturbs reasonable persons with normal sensitivities; or any sound which injures or endangers the comfort, repose, health, hearing, peace or safety of other persons. This definition does not apply to the content of words or speech in themselves as a disturbance.
PERSON
Any individual, association, partnership or corporation and includes any officer, employee, department, agency or instrumentality of the United States, a state or any political subdivision of that state.

PURE TONE
Any noise which can be distinctly heard as a single pitch or a set of single pitches. For the purposes of measurement, a "pure tone" shall exist if the one-third octave band sound pressure level is the band which the tone exceeds the arithmetic average of the sound pressure levels of the two contiguous one-third octave bands by five dB for frequencies of 500 hertz and above, by eight dB for frequencies between 160 and 400 hertz and by 15 dB for frequencies less than or equal to 125 hertz.
REPETITIVE IMPULSIVE NOISE
Any noise which is composed of impulsive noises that are repeated at sufficiently slow rates such that a sound level meter set at fast meter characteristic will show changes in sound pressure level greater than two dB(A).
SOUND
A temporal and spatial oscillation in pressure or other physical quantity in a medium with internal forces that causes compression and rarefaction of that medium and that propagates at finite speed to distant points.
SOUND LEVEL METER

SOUND PRESSURE
The instantaneous difference between the actual pressure and the average or barometric pressure at a given point in space.
