(A) For the purpose of this chapter, the following definitions shall apply unless the context indicates or requires a different meaning.
A-WEIGHTED SOUND LEVEL. The sound pressure level in decibels as measured on a sound level meter using the A-weighting network. The level so read is designated as db(A) or dbA.
DECIBEL (DB). 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 micro-newtons per square meter).
LIGHT MOTOR VEHICLE. Any automobile, van, motorcycle, motor driven cycle, motor scooter, dune buggy, snowmobile, all-terrain vehicle, go-cart, minibike, trail bike, or truck with a gross vehicular weight of less than 8,000 pounds.
MINOR. A person under 18 years of age.
MODIFIED AND DEFECTIVE EXHAUST SYSTEMS. An exhaust system in which the original noise abatement devices have been physically altered,
causing them to be less effective in reducing noise than their original devices, or devices which have been added to the original noise abatement devices so that noise levels are increased.
NOISE LEVEL. The A-weighted sound level produced by or from a motor vehicle.
PERSON. Any individual, association, partnership, or corporation which includes any officer, employee, department, agency, or instrumentality.
SOUND LEVEL METER. An instrument which includes a microphone, amplifier, RMS detector, integrator or time average, output meter, and weighting networks used to measure sound pressure levels. This instrument shall be used for measurement of the intensity of sound and calibrated in decibels as standardized by the American National Standards Institute (ANSI). Readings shall be made on a db(A) scale.
TOWN OF CHANDLER OWNED PROPERTY. Any right-of-way, property in which the town is the title holder of record, or property in which the town owns a leasehold interest.
TRAFFIC NOISE. Sound made by or from a motor vehicle operated either on public property or right-of-way or on private property.
(B) All definitions and terminology used in this chapter and not defined above, shall be defined in conformance with an applicable publication of the American National Standards Institute (ANSI), or its successor body.
