A.         Sound levels shall be measured with a sound level meter or sound level meter with associated octave band analyzer that conforms to standards and specifications published by the American Standards Association.  Impulsive-type noise shall be subject to the performance standards hereinafter prescribed, provided that such noise shall be capable of being accurately measured with such equipment.  Noise capable of being so measured, for the purpose of this chapter, shall be those noises which cause rapid fluctuations of the needle of the sound level meter with a variation of not more than plus or minus (+ or -) two (2) decibels.  Noise incapable of being so measured, such as those of an irregular intermittent nature, shall be controlled so as not to become a nuisance to adjacent uses.  (American Standard Sound Levels for Measurement of Noise and Other Sounds, 224, 3-1944, American Standards Association, Inc., New York, New York, shall be used.)

B.         No activity may transmit noise across any residential, commercial or industrial use property boundary line in excess of levels established below:

 

Maximum Permitted Sound Level in Decibels (Re .0002 microbar)
Within Following Zoning District		7:00 a.m. to 7:00 p.m.		7:00 p.m. to 7:00 a.m.
CR, MDR,  OSPC		55		50
TC, RB, HC, PORBP		65		60
PIP		70		65

 

OR

 

Maximum Permitted Sound Level in Decibels (RE .0002 microbar)
Octave Band Cycles/Second (preferred center frequency)		7:00 a.m. to 7:00 p.m.		7:00 p.m. to 7:00 a.m.
31.5		79		73
63.0		74		68
125.0		68		62
250.0		60		54
500.00		55		49
1,000.0		50		44
2,000.0		46		40
4,000.0		41		35
8,000.0		38		32

 

C.         Impulsive type noises generated by sources that do not operate more than one (1) minute in any one-hour period are permissible up to a level of ten (10) dB(A) in excess of the figures listed in Subsection B except that this higher level of permissible noise shall not apply from 7:00 p.m. to 7:00 a.m. when the adjacent lot is zoned residential.  The noise shall be measured using the fast response of the sound level meter.

D.         Noise resulting from alarms, sirens, emergency work, normal lawn and landscaping care, traffic and agricultural use shall be exempt from the requirements of this section.  Noise resulting from temporary construction activity that occurs between 7:00 a.m. and 7:00 p.m. shall be exempt from the requirements of this section, except that such activity that occurs on Sundays shall be exempt from the requirements of this section from 9:00 a.m to 7:00 p.m.

E.         No noise from recordings, loudspeakers or public address systems shall be allowed which interferes with the reasonable enjoyment of adjacent residential properties.
