Upon receipt of a complaint from a citizen, the Chief of Police or his or her designated representative, equipped with a sound level meter, shall investigate the complaint. The investigation shall consist of a measurement and the gathering of data to define adequately the noise problem and shall include the following.
(A) Non-acoustic data.
(1) Type of noise source;
(2) Location of noise source relative to complainant’s property;
(3) Time period during which noise source is considered by complainant to be intrusive;
(4) Total duration of noise produced by noise source; and
(5) Date and time of noise measurement survey.
(B) Noise measurement procedure:
(1) Utilizing the A weighting scale of the sound level meter and the “slow” meter response (use “fast” response for impulsive type sounds), the noise level shall be measured at a position or positions at any point on the complainant’s property line.
(2) In general, the microphone shall be located four to five feet above the ground, ten feet or more from the nearest reflective surface, where possible; however, in those cases where another elevation is deemed appropriate, the latter shall be utilized. Calibration of the measurement equipment, utilizing an acoustic calibrator, shall be performed immediately prior to recording any noise data.
