§ 272-3. Prohibited noise levels.

A. 

Determination of noise levels.

(1) 

No person shall operate or cause to be operated any mechanism or device which shall create a noise within the Village exceeding the limiting noise levels set forth in the following table:

	Octave Band Center Frequency in Hertz (CPS)	Sound Pressure Level in Decibels Above 0.0002 Microbar
	63	70
	125	63
	250	56
	500	49
	1,000	45
	2,000	40
	4,000	38
	8,000	35

(2) 

The above values refer to smooth and continuous noise; however, in the event that the noise is not smooth and continuous and is not radiated at nighttime, one or more of the following corrections shall be added to or subtracted from each of the decibel levels given above:

	Type of Operation or Character of Noise	Correction (dBs)
	Daytime operation only	+5
	Noise source operates less than 20% of any 1 hour	+5*
	Noise source operates less than 5% of any 1 hour	+10*
	Noise source operates less than 1% of any 1 hour	+15*
	Noise of impulsive character	-5
	Noise of periodic character	-5

	NOTE:
	*	Apply one of these corrections only.

B. 

Noise measurements required under the terms of this chapter shall be made by the use of an octave band analyzer as defined herein.

C. 

Noise measurements and limits shall conform to the following practices:

(1) 

Noise shall be measured at least four feet above ground level but not more than at an altitude exceeding 40 feet above ground level.

(2) 

Facility noise originating on residential property shall be measured at the property on which the noise source is located.

(3) 

Facility noise originating on business or commercial property shall be measured at the property line of the nearest residential property.
