§ 23.06.050. Noise Level Measurement.

For the purpose of evaluating conformance with the standards of this chapter, noise levels shall be measured as follows:

a.

Use of meter: Any noise measurement made pursuant to the provisions of Sections 23.06.044-048 shall be made with a sound level meter using the A-weighted network (scale). Calibration of the measurement equipment utilizing an acoustical calibrator shall be performed immediately prior to recording any noise data.

b.

Measuring exterior noise levels: Except as otherwise provided in Sections 22.06.044-048, exterior noise levels shall be measured at the property line of the affected noise-sensitive land use listed in Section 23.06.044. Where practical, the microphone shall be positioned five feet above the ground and away from reflective surfaces.

c.

Measuring interior noise levels: Interior noise levels shall be measured within the affected residential use listed in Section 23.06.046, at points at least four (4) feet from the wall, ceiling or floor nearest the noise source, with windows in the normal seasonal configuration. The reported interior noise level shall be determined by taking the arithmetic average of the readings taken at the various microphone locations.
