In addition, as used in this chapter, the terms listed below shall have the following meanings:
(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) “Decibel” (dB) means a unit of sound pressure measurement as defined in the American National Standards Institute Bulletin.
(3) “dB(A)” refers to a weighted scale for measuring decibels as defined in the American National Standards Institute Bulletin.
(4) “Light motor vehicle” means any automobile, van, motorcycle, motor- driven cycle, motor scooter, dune buggy, snowmobile, all-terrain vehicle, go-cart, minibike, trail bike, dirt bike or truck with a gross vehicular weight of less than 8,000 pounds.
(5) “Modified exhaust system” means an exhaust system in which the original noise abatement devices have been physically altered, causing them to be less effective in reducing noise, or in which the original noise abatement devices have either been removed or replaced by noise abatement devices which are not as effective in reducing noise as their original devices, or in which devices have been added to the original noise abatement devices so that noise levels are increased.
(6) “Noise level” refers to the A-weighted sound level produced by a motor vehicle.
(7) “Person” means any individual, association, partnership or corporation and includes any officer, employee, department, agency or instrumentality.
(Ord. 111-2000. Passed 7-11-00.)
(8) “Sound level meter” means an instrument that conforms to ANSI S1.4- 1983, “American National Standard - Specification for Sound Level Meters”, or its successors.
(Ord. 34-2001. Passed 4-10-01.)
(9) “Traffic noise” means sound made by a motor vehicle operated either on a public right of way or on private property.
(b) Light Motor Vehicle Noise.
(1) No person shall cause noise levels from the operation of a light motor vehicle in excess of eighty dB(A) in any area of the City, at any time of the day, regardless of the specified speed limit, where the speed limit is not more than forty-five miles per hour. Such noise level limits of eighty dB(A) shall be based on a distance of not less than fifteen feet from the noise source.
(2) Whoever violates this subsection is guilty of a minor misdemeanor for the first offense, a fourth degree misdemeanor for any second offense occurring within six months of a first offense, and a third degree misdemeanor for subsequent offenses occurring within six months of a previous offense.
(c) Modified Exhaust Systems; Revving; Tire Squealing.
(1) No person shall operate a motor vehicle which causes noise levels in excess of eighty dB(A) in any area of the City as a result of a defective or modified exhaust system which noise level limits shall be based on a distance of not less than fifteen feet from the noise source. No person shall operate a motor vehicle which causes excessive noise levels as a result of unnecessary rapid acceleration, deceleration, revving or tire squealing.
(2) Whoever violates this subsection is guilty of a minor misdemeanor for the first offense, a fourth degree misdemeanor for any subsequent offense occurring within six months of a first offense, and a third degree misdemeanor for subsequent offenses occurring within six months of a previous offense.
