meter to become wet; or when the ambient temperature is out of range of tolerance on the <br /> sound meter. <br /> 4. Calibration: The sound level meter must be verified and calibrated according to the <br /> manufacturer's specifications immediately prior to taking the measurements. <br /> 5. Meter Placement: The sound level meter must be placed a minimum of four feet above <br /> the ground or from any reflective surface. The microphone must be pointed at the sound <br /> source. <br /> 6. Measurements: Measurements must include"high", "average", and"low"readings. If the <br /> sound level meter does not provide these multiple readings, a minimum of three separate <br /> measurements must be taken at a single location at varying time intervals. The average <br /> sound level reading shall be used to determine whether there has been a violation of this <br /> Ordinance. <br /> 7. Monitoring Report: The report for each measurement session must include: <br /> a. The day, date and time of the measurements, <br /> b. Date and time of recent calibration, <br /> c. Temperature and wind speed the time of measurement, <br /> d. Identification of the monitoring equipment, <br /> e. Location, land use, and description of the source, <br /> f. Location and land use of the listener, and <br /> g. Sound level measurements. <br /> 8. Extraneous Sounds: If there are extraneous sound sources that are unrelated to the <br /> measurements and increase the monitored sound level,the measurement shall be <br /> postponed until these noises subside. <br /> ARTICLE 5: Noise Limitations <br /> It shall be unlawful for any Data Center to make, or continue to cause or permit to be made or <br /> continued, noise levels constituting a noise disturbance. For the purposes of this section,the <br /> external noise level emanating from Data Centers shall be deemed disturbing to a person, <br /> reasonably calculated to disturb the peace and unreasonably offensive and injurious to the public, <br /> or their property, if the sound level is: <br /> 1. 65 dBa or higher during the hours of 8 A.M.to 10 P.M. or 55 dBa or higher during the <br /> hours of 10 P.M. to 8 A.M. (as determined by a third-party acoustic engineer)measured <br /> at the property line of the receiving property. <br /> 2. The standard which may be considered in determining whether a violation of this <br /> Ordinance exists includes but is not limited to the following: <br /> a. The level or volume of the noise <br /> b. The time of day or night the noise occurs <br /> c. The duration of the noise <br /> d. Whether the noise is recurrent, intermittent or constant <br /> 5 <br />
