�T ���-0�6� - �n�e � <br />TEST METHODS <br />Our monitoring was performed with a Larson-Davis Laboratories Mode1700 Sound L,evel Meter <br />with calibration traceable to NIST. This equipment meets the equipment specifications for a Type <br />II Meter (ANSI 51.4-1983}. The A-Weighting Network on fast mode was used for all of ow <br />monitoring. The A-weightingnetwork attempts to duplicate the ear's sensitivity by discriminating <br />against low frequencynoise since humans are muc� za�nte sensitiveto noise with a higher frequency. <br />At each location, the meter was placed at the required height above the surface. Care was taken to <br />avoid as much error as possible caused by reflecting obj ects or s�rfaces. The monitor was placed <br />down wind fram the noise source. <br />We remained in the vicinity of the monitoring locations during the monitoringperiod to document <br />specific events which resulted in readings above the normal noise levels. <br />. ,. <br />This data is for informational purposes only and was not performed for any one particular set of <br />regulations or local ordinance standards. <br />The raw noise data will be retained in our file aald is available to you on request. If you have any <br />questions regardingthis report, please contact Jason Crowley. <br />Report Prepared by: Report Reviewed by: <br />American EngineeringTesting, Inc. l�nteric� E.n�ri�tin�, [ac, <br />�� r <br />�_ r <br />� - •�.
