The following procedures shall be utilized for measuring and evaluating exterior noise in the city unless otherwise specified in this chapter:
(A) Noise measurements shall be conducted any time during the day or night when the suspect noise source is in operation.
(B) The location selected for noise measurement shall be on the noise receptor's property line at a point approximately ten feet from any building, wall or obstruction (trees, bushes, etc.).
(C) No individual other than the operator shall be within ten feet of the sound level meter during the measurement period.
(D) The sound level meter shall be calibrated in accordance with the manufacturer's instructions.
(E) With the noise source in operation, the operator shall record the instantaneous response at 15-second intervals or less, for a period of 15 minutes or greater. Or, for a noise source in operation for less than 15 minutes, the operator shall record the instantaneous response at 15-second intervals or less for the time the noise source is in operation.
(F) The suspect noise source shall only be measured for a violation of this subchapter when it is five dBA or greater than another noise source within the measurement vicinity.
(G) The corrective factors set forth in § 130.34(B) shall be applied to the noise standard established for the specific noise zone.
(H) The suspect noise level shall be compared with the standards in § 130.34(A). If the noise level generated from the suspect noise source exceeds the standard, the suspect noise source shall be considered to be in violation of this chapter.
