The following procedures must be used <br />to obtain a representative sound level measurement by the use of a sound measuring <br />device: <br /> <br />a. A decibel meter will be used to obtain readings and be used as <br /> evidence. <br /> <br />The operator of the device has sufficient training to properly operate <br />the equipment and can testify as to the manner in which the device <br />was set up and operated. <br /> <br />c. The device is operated with minimal distortion or interference from <br /> outside sources; and has been certified as being accurate and reliable. <br /> <br />do <br /> <br />Measurements must be made at least three (3) feet off the ground or <br />surface and away from natural or artificial structures which would <br />prevent an accurate measurement. <br /> <br />Measurements must be made using an A-weighting and fast response <br />characteristics of the sound measuring device as specified in American <br />National Standards Institute S 1.4-1983. <br /> <br />f. Measurements must not be made in sustained winds or in precipitation <br /> <br />which results in a difference of less than ten (10) decibels between the <br />background noise level and the noise source being measured. <br /> <br />Measurements must be made using a microphone which is protected <br />from ambient conditions which would prevent an accurate <br />measurement. <br /> <br />h. Measurement must be made from the property of the person making the <br /> complaint, when applicable. <br /> <br />H!ster'.'ea!
