Measurement with sound level meter.
(1) The measurement of sound shall be made with a sound level meter meeting the standards prescribed by ANSI S1.4-1971 (R1976). The instruments shall be maintained in calibration and in good working order. A calibration check shall be made of the system at the time of any sound level measurement. Measurements shall be taken so as to provide a proper representation of the source of the sound. The microphone during measurement shall be positioned so as not to create any unnatural enhancement or diminution of the measured sound. A windscreen for the microphone shall be used at all times. However, a violation of this Article may occur without the occasion of the measurements being made as otherwise provided.
(2) The slow meter response of the sound level meter shall be used in order to best determine the average amplitude.
(3) The measurement shall be made at any point from at least twenty-five (25) feet away from any ground, wall, floor, ceiling, roof and other plane surface.
(4) In case of multiple occupancy of a property, the measurement may be made at any point inside the premises to which any complainant has right of legal private occupancy, provided that the measurement shall not be made within three (3) feet of any ground, wall, floor, ceiling, roof or other plane surface.
