The following words and terms, as used herein shall have the following meanings:

- SOURCE OF COMPLAINT
- The location on the property adjacent to that property which

complainant.[Added 12-13-1976 by Ord. No. 1649]
- SPORADIC NOISE
- Any noise which does not normally continue for a period of time necessary to obtain decibel readings in all frequency bands.
It shall be unlawful for any person in the operation of an air conditioning unit or units and equipment or other types of mechanical equipment or apparatus installed in or attached to buildings or located on premises appurtenant to buildings to make or produce excessive noise, thereby causing annoyance, inconvenience or detriment to the public or to any other person or persons. Noise shall be considered excessive if the sound pressure from the air-conditioning unit or units and equipment or other type of mechanical equipment or apparatus exceeds the limits hereinafter set forth.
During daytime hours, the maximum permissible sound pressure levels at specified points of measurement for continuous noise radiated from premises shall not exceed the following:
During nighttime hours, the maximum permissible sound pressure levels at specified points of measurement for continuous noise radiated from premises shall not exceed the following:
When the source of complaint originates inside of a building or structure, the microphone shall be placed three feet from the nearest window in the room where the source of complaint originates and not less than three feet above the floor, in which case the inside table of sound pressure levels shall be used.
When the source of complaint originates outside, the microphone shall be placed at the source of the complaint but no closer than three feet to any wall and not less than three feet above the ground, in which case the outside table of sound-pressure levels shall be used.
If as a result of such test the air-conditioning unit and equipment or other mechanical equipment or apparatus is found to violate the provisions of this chapter, the operation thereof shall forthwith be discontinued and not be resumed unless and until proper corrections have been made therein, which shall first have been approved by the Director of Code Enforcement.
[Amended 6-30-1986 by Ord. No. 1960]
No person shall create any sporadic noise which, when measured in the 600 to 1,200 cycles per second frequency band, exceeds a soundpressure level of 57 decibels during daylight hours or 52 decibels during nighttime hours.
Sound levels shall be measured with a sound-level meter and associated octave band analyzer manufactured according to standards prescribed by the American Standards Association.
Traffic noises, noises created by governmental units and noises created by emergency and civil defense activities shall be exempt from the application of this chapter.
Noises created by construction work and the repair and maintenance of any building or structure shall be exempt, but only during the hours of 8:00 a.m. to 6:00 p.m.
