[Derived from Section 30B of the General Code of Ordinances]
Subject to the provisions of this article, the creation of any unreasonably loud, disturbing and unnecessary noise is prohibited. Noise of such character, intensity and duration as to be detrimental to the life or health of any individual is prohibited.
The following acts, among others, are declared to be loud, disturbing and unnecessary noises in violation of this section, but any enumeration herein shall not be deemed to be exclusive: The operation of any machinery, motor vehicle, equipment, pump, exhaust fan, attic fan, air-conditioning apparatus or similar mechanical device, television, radio, phonograph, loading or unloading of vehicles, or use of any instrument in such a manner or with such volume as to annoy or disturb the quiet, comfort or repose of any person or persons in any dwelling, hotel or other type of residence or in such a manner or with such volume as to create any noise in excess of the sound pressure levels hereinafter designated.
A. 
Except for noise emanating from the operation of motor vehicles, the permissible intensity of noise from the foregoing acts between the hours from 7:00 a.m. to 10:00 p.m. and from 10:00 p.m. to 7:00 a.m., respectively, whether such noise is intermittent, impulsive, sporadic or continuous, is as follows:

B. 
Except for noise emanating from the operation of motor vehicles, the point at which the intensity of sound is to be measured shall be as follows:
(1) 
For noise emanating from a source in a Residential Zoned District: at any adjoining property line.
(2) 
For noises emanating from a source in any district other than a Residence Zoned District: at the Residence District boundary line.
C. 
Noise emanating from the operation of motor vehicles shall not exceed a sound pressure level measured on the A scale of a sound meter at a distance from the longitudinal center line of the vehicle as follows:

Upon the trial of any action or proceeding arising out of acts committed by any person creating unreasonably loud, disturbing and unnecessary noise, the court may admit evidence of sound pressure levels in decibels as shown by a sound level meter, octave band analyzer and impact noise analyzer. For the purpose of this section, evidence that noise exceeding the maximum sound pressure levels in decibels as provided in Subsections A and C hereof may be admitted as prima facie evidence that the noise was unreasonably loud, disturbing and unnecessary.
