§ 2-22-58. Measurement techniques.

(a)

Noise measurements shall be made at the nearest adjacent property line from the property on which the noise source is located. Such noise measurements shall be made at a height of at least four (4) feet above the ground and at a point approximately ten (10) feet away from walls, barriers, obstructions (trees, bushes, etc.) on a sound level meter operated on the "A" weighting level.

(b)

The ambient base noise level shall be determined with the noise source not in operation prior to or after a measurement. The ambient base noise level shall be determined as follows:

(1)

Calibrate the sound level meter immediately before use.

(2)

Set the sound level meter on the "A" weighted network at a fast response.

(3)

Without the noise source in operation, set the omni-directional microphone in a vertical position in a location which complies with subsection (a). The operator of the sound level meter shall face the noise source and record the meter's instantaneous response.

(c)

It shall be unlawful for any person to refuse to cease making any sound when so ordered by duly authorized personnel, for the purpose of measuring the ambient base noise level.
