(a) 
Any unreasonably loud or disturbing noise that causes material distress, discomfort or injury to persons of ordinary sensibilities in the immediate vicinity thereof is hereby declared to be a nuisance and is hereby prohibited. A noise is considered unreasonably loud or disturbing if it is measured above 85 decibels (dBA) beyond the property of the source, or 50 feet or more from the source if in a public right-of-way; or if the noise creates a vibration which is above the vibration perception threshold of an individual beyond the property of the source, or 50 feet or more if in a public right-of-way. It shall be prima facie evidence that the decibel level is above 85 if the instrument used to measure the noise level is approved by the city police department and applied so as to provide a proper representation of the sound being measured.
(b) 
Additionally, no person shall cause, suffer, allow, or permit any of the following acts, which are declared to be noise nuisances. If a noise is made on property which falls under more than one of the four categories enumerated in this section, the lowest maximum decibel level shall apply.
(1) 
The making of noise which exceeds 85 decibels between the hours of 7:00 a.m. and 9:59 p.m. or 56 decibels between the hours of 10:00 p.m. and 6:59 a.m. in residential areas and all abutting public rights-of-way;
(2) 
The making of noise which exceeds 85 decibels between the hours of 7:00 a.m. and 9:59 p.m. or 63 decibels between the hours of 10:00 p.m. and 6:59 a.m. on commercial or other business zoned property as defined by the zoning ordinance of the city;
(3) 
The making of noise which exceeds 85 decibels between the hours of 7:00 a.m. and 9:59 p.m. or 65 decibels between the hours of 10:00 p.m. and 6:59 a.m. on industrial zoned property as defined by the zoning ordinance of the city; or
(4) 
The making of noise which exceeds 85 decibels between the hours of 7:00 a.m. and 9:59 p.m. or 65 decibels between the hours of 10:00 p.m. and 6:59 a.m. on any property which does not fit into any of the categories described in the foregoing subsections (1), (2) and (3) of this section.
