As used in this chapter, the following terms shall have the meanings as indicated:
DECIBEL (DB)A unit for measuring the amplitude of 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.
EMERGENCYAny occurrence or set of circumstances involving actual or imminent physical trauma, or property damage which requires immediate action.
IMPULSIVE SOUNDSound of short duration, usually less than one second, with an abrupt onset and rapid decay. Examples of impulsive sounds include explosions, drop impacts and firearm discharges.
MOTOR VEHICLEEvery vehicle which is not self-propelled, except an electrically driven invalid chair being operated or driven by an invalid, which includes but is not limited to a passenger vehicle, truck, truck-trailer, trailer or semitrailer, motorcycle, snowmobile, minibike and Go-Kart.
MULTIFAMILY DWELLINGAny housing unit where two or more dwellings are separated by a common wall, floor, or ceiling, including but not limited to apartments, condominiums and townhouses.
NOISE LEVELThe amplitude of sound pressure referenced to 20 micropascals, measured in decibels, using the A-weighting network (for the purposes of this chapter).
NOISE LEVEL MEASUREMENTThe procedure of measuring sound consisting of the usage of a precision sound level meter (SLM), as defined in this section, set to "fast" response. If the sound level meter is analog with a VU meter, then the response shall be "slow" unless the noise issue is impulsive. The meter must be calibrated before any measurements and the microphone shall be a minimum of 3 1/2 feet from any wall, floor or other large sound-reflecting surface. The meter shall be protected from wind or other extraneous noise by the use of screens, shields or other appropriate devices.
OWNERIncludes the owner of the freehold of the premises or lessor estate therein; or mortgagee thereof, a lessee or agent of any of the above persons, a lessee of a device or his agent, a tenant, operator or any other person who has regular control of a building, device or an apparatus.
PERSONAny individual, association, partnership or corporation, including any officer, employee, department, agency or instrumentality of the state or any political subdivision of a state.
PRECISION SOUND LEVEL METERA sound pressure level measuring instrument which conforms to the American National Standards Institute (ANSI) specification S1.4 for Type 1 or Type 2 measuring instruments.
REAL PROPERTY BOUNDARYA line along the ground surface and its vertical extension, which separates the real property owned by one person from that owned by another person.
RESIDENTIAL PROPERTYAny property legally used for a single-family, two-family or multifamily dwelling as defined in the Zoning Chapter.
SOUND DEVICE OR APPARATUSAny apparatus or device for the making, reproduction or amplification of the human voice or other sounds.
