Sec. 20-24. Classification and measurement of noise.
For the purposes of classifying any noise disturbance and determining whether
it is in violation of§ 20-23,the following test measurements and requirements shall
be applied; provided, however, that a violation of§ 20-22 may occur without the
following measurements being made:
(1) Noise shall be measured at a distance of at least twenty-five(25)feet from
a noise source located within the public right-of-way, and if the noise
source is located on private property or public property other than the
public right-of-way,the noise shall be measured at or within the property
boundary of the receiving land use.
(2) The noise shall be measured on a sound level meter.
(3) No outdoor measurement shall be taken without a wind screen
recommended by the sound level meter manufacturer, or during periods
when wind speeds, including gusts, exceed fifteen(15) miles per hour.
See. 20-25. Exceptions.
The provisions of this Article shall not apply to:
(1) Noise from emergency signaling devices;
(2) Noise from agricultural activities;
