§ 13-6-4. Measurement of Noise.

(a)

The measurement of sound or noise shall be made with a sound level meter and octave band analyzer meeting the standards prescribed by ANSI S1.4-1971, TYPE 1 and IEC 179. The instruments shall be maintained in calibration and good working order. Octave band corrections may be employed in meeting the response specifications. A calibration check shall be made of the system at the time of any noise measurement. Measurements recorded shall be taken so as to provide a proper representation of the noise source. The microphone during measurement shall be positioned so as not to create any unnatural enhancement of diminution of the measured noise. A windscreen for the microphone shall be used when required. Traffic, aircraft and other transportation noise sources and other background noises shall not be considered in taking measurements except where such background noise interferes with the primary noise being measured.

(b)

The slow meter response of the sound level shall be used in order to best determine that the average amplitude has not exceeded the limiting noise spectra set forth in Table I.

(c)

The measurement shall be made at the property line of the property on which such noise is generated, or perceived, as appropriate, five (5) feet above ground.

(d)

In the case of an elevated or directional sound or noise source, compliance with the noise limits is to be maintained at any elevation at the boundary. The limits hereinabove referred to shall be in accordance with the Tables set forth in Section 13-6-5.
