When this subchapter requires measurement of the sound level, the measurement shall be as follows.
(A) The measurement of sound or noise shall be made with sound level meters Type 1 or Type 2 which meet the standards prescribed by the ANSI. The instruments shall be maintained in calibration and good working order. A calibration 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 or diminution of the measured noise. A windscreen for the microphone shall be used. A minimum of three sound level readings will be taken. The geometric mean of these readings will be used as the average sound level. If the background noise is equal to the levels set forth in § 92.06, three dB shall be subtracted out of the average sound level.
(B) The slow meter response of the sound level meter shall be used to determine that the average amplitude has not exceeded the dBA readings or the limiting noise spectra set forth in § 92.06.
(C) Unless otherwise specified in this subchapter, the measurement shall be made at:
(1) The property boundary on which such noise is generated;
(2) Any point within the receiving property affected by the noise; or
(3) Any public area including, but not limited to, any public streets, docks or sidewalks.
