As used in this chapter, the following terms shall have the meanings indicated:
Any sound (i.e., voice, music, or other noise) created, enhanced, or amplified through the use of equipment, including, but not limited to, speakers, amplifiers, sound systems, stereos, and bullhorns.
The sound pressure level in decibels as measured on a sound level meter using the A-weighting network. The level so read is designated "dB(A)" or "dBa."
Any site preparation, assembly, erection, substantial repair, alteration or similar action, but excluding demolition, for or of public or private rights-of-way, structures, utilities or similar property.
The twenty-four-hour energy average of the A-weighted sound pressure level, with the levels during the period of 10:00 p.m. to 7:00 a.m. the following day increased by 10 dBa's before averaging.
A unit for measuring the volume of a sound, equal to 20 times the logarithm to the base 10 of the ratio of the pressure of the sound measured to the reference pressure, which is 20 micropascals (20 micronewtons per square meter).
Any dismantling, intentional destruction or removal of structures, utilities, public or private right-of-way surfaces or similar property.
Any occurrence or set of circumstances involving actual or imminent physical trauma or property damage which demands immediate action.
Any work performed for the purpose of preventing or alleviating the physical trauma or property damage threatened or caused by an emergency.
The constant sound level that, in a given situation and time period, conveys the same sound energy as the actual time-varying A-weighted sound. For the purposes of this chapter, a time period of 24 hours shall be used, unless otherwise specified.
The value specified by the manufacturer as the recommended maximum loaded weight of a single motor vehicle. In cases where trailers and tractors are separable, the gross combination weight rating (GCWR), which is the value specified by the manufacturer as the recommended maximum loaded weight of the combination vehicle, shall be used.
Sound of short duration, usually less than one second, with an abrupt onset and rapid decay. Examples of sources of impulsive sound include explosions, drop forge impacts and the discharge of firearms.
Any vessel which operates on water and which is propelled by a motor, including but not limited to boats, barges, amphibious crafts, water-ski towing devices and hover craft.
Any vehicle for which regulations apply pursuant to Section 18 of the Federal Noise Control Act of 1972 (P.L. 92-574), as amended, pertaining to motor carriers engaged in interstate commerce.
As defined in the Motor Vehicle Code of the State of New Jersey.
As defined in the Motor Vehicle Code of the state.
A device for abating the sound of escaping gases of an internal-combustion engine.
Any sound which annoys or disturbs humans or which causes or tends to cause an adverse psychological or physiological effect on humans.
Any sound which endangers or injures the safety or health of humans or animals or annoys or disturbs a reasonable person of normal sensitivities or endangers or injures personal or real property.
Any area designated for the purpose of ensuring exceptional quiet.
Any street, avenue, boulevard, highway, sidewalk or alley or similar place which is owned or controlled by a governmental entity.
Any real property or structures thereon which are owned or controlled by a governmental entity.
Any imaginary line along the ground surface, and its vertical extension, which separates the real property owned by one person from that owned by another person, but not including intrabuilding real property divisions.
The square root of the time averaged square of the sound pressure, denoted P rms.
An oscillation in pressure, particle displacement, particle velocity or other physical parameter, in a medium with internal forces, that causes compression and rarefaction of that medium. The description of sound may include any characteristic of such sound, including duration, intensity and frequency.
The weighted sound pressure level obtained by the use of a sound level meter and frequency weighting network, such as A, B or C as specified in American National Standards Institute specifications of sound level meters. If the frequency weighting employed is not indicated, the A-weighting shall apply.
An instrument which includes a microphone, amplifier, RMS detector, integrator or time averager, output meter and weighting networks used to measure sound pressure levels and meets ANSI S-1.4.
The instantaneous difference between the actual pressure and the average or barometric pressure at a given point in space, as produced by sound energy.
Twenty times the logarithm to the base 10 of the ratio of the RMS sound pressure to the reference pressure of 20 micropascals (20 times 10-6 newtons per square meter). The sound pressure level is denoted L p or SPL and is expressed in decibels.
An oscillatory motion of solid bodies of deterministic or random nature described by displacement, velocity or acceleration with respect to a given reference point.
