(a) Definitions. All terminology used in this section, not defined below, shall be in conformance with applicable publications of the American National Standards Institute (ANSI) or its successor body and are on file in the office of the Village Administrator.
(1) "A-weighted sound level" means 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.
(2) "Noise level" means the A-weighted sound level produced by a light motor vehicle.
(3) "Person" means any individual, association, partnership or corporation, and includes any officer, employee, department, agency or instrumentality of a State or any political subdivision of a State.
(4) "Sound level meter" means an instrument which includes a microphone, amplifier, RNS detector, integrator or time averager, output meter and weighing networks used to measure sound pressure levels. The instrument shall comply with the standards for Type 1 or Type 2 sound level meters as specified in American National Standards Institute Standard ANSI S1.41971 or its successor.
(5) "Sound pressure level" means twenty times the logarithm to the base ten of the ratio of the RMS sound pressure to the reference pressure of twenty micro-pascals. The sound pressure level is expressed in decibels.
(6) "Noise" means any sound which annoys or disturbs humans or which causes or tends to cause an adverse phychological or physiological effect on humans.
(7) "Light motor vehicle" means any automobile, van, motorcycle, motor driven cycle, motor scooter or truck with gross vehicular weight of less than 10,000 pounds.
(8) "Modified exhaust system" means an exhaust system in which:
A. The original noise abatement devices have been physically altered causing them to be less effective in reducing noises;
B. The original noise abatement devices have been either removed or replaced by noise abatement devices which are not as effective in reducing noise as the original devices; or
C. Devices have been added to the original noise abatement devices, such that noise level are increased.
(b) Eighty dBA Noise Limit.
(1) It shall be unlawful for any person to cause noise levels from the operation of a light motor vehicle in excess of eighty dBA in any area within the corporate limits of the Village. Measurements shall be made on pedestrian walkways or on other suitable locations at a point no less than fifteen feet from the near edge of the closest usable land in accordance with procedures outlined in the Code of Recommended Practices on file in the office of the Village Administrator. The Village Administrator shall have copies at cost.
(2) This section shall not apply to public service vehicles nor public safety vehicles.
(c) Excessive Noise. In addition to any other prohibition in the ordinances of the Village, it shall be unlawful for any person to operate a light motor vehicle which causes excessive noise levels as a result of a defective or modified exhaust system, or as a result of unnecessary rapid acceleration, deceleration, horn blowing, revving, tire squeal or use of radios, stereos and accessories. At the request of the operator of the light motor vehicle, the officer may administer a stationary motor vehicle noise test as outlined in the Code of Recommended Practices on file with the Village Administrator. The stationary motor vehicle noise test can provide information as to the extent of defectiveness of the exhaust system or as to whether excessive noise levels were caused by improper operation of the light motor vehicle.
(d) Severability. If any section, subsection, sentence, clause, phrase or portion of this section is for any reason held invalid or unconstitutional by any Court or agency of competent jurisdiction such portion shall be deemed a separate, distinct and independent provision and such ruling or holding shall not affect the continued effectiveness, validity or enforcement of the remaining portions.
(e) Penalty. Whoever violates a section of this chapter is guilty of a misdemeanor of the fourth degree.
