Method of sound mteaunmemelllllt <br />Whenever portions of this chapter prohibit sound over a certain decibel limit, <br />measurement of said sound shall be made with a Type 1 or Type 2 calibrated <br />sound level meter utilizing the Aweighting scale and the slow meter response as <br />specified by the American National Standards Institute (ANSI S141984/85A). <br />Noise levels shall be measured in decibels and A-weighted. The unit of <br />measurement shall be designated as Db(A). Meters shall be maintained in <br />calibration and good working order. Measurements recorded shall be taken so as <br />to provide a proper representation of the sound being measured. The microphone <br />of said meter shall be positioned so as not to create any unnatural enhancement of <br />diminution of the measured sound. A windscreen for said microphone shall be <br />used. Except as provided in Sections 34-94 and 34-95, measurements shall be <br />taken at or near the nearest property line of the property where the sound is being <br />received. <br /> <br />Sec1tioI!l 34-97.
