Determination of Ambient Noise Levels Sample Clauses

Determination of Ambient Noise Levels. The objectives of the baseline noise study were: i) to measure ambient noise levels; and ii) to identify recurring sources of noise in the vicinity of the proposed Project that may influence the measured levels. The first field program was undertaken on June 2nd and 3rd, 2008 and involved the automatic recording of sound levels at two on the Donkin peninsula over a 24 hour period. The recording locations, as depicted on Figure 3.4, are as follows: ⮚ Location 1 - at the former Xxxxxx Homestead; and ⮚ Location 2 - south of the proposed mine site towards Morien Bay. The weather during the sampling period was mainly clear as reported in the hourly data attained from EC. All measurements were taken using an Extech Sound Level Meter. The sound level was measured as Leq, which is the logarithmic average over a measurement time. Leq measurements at each location were logged once per minute over a 24-hour period. The measurement unit selected for the evaluation was dBA, or “A” weighted decibels. A fast response time was selected to capture both noise peaks and noises that occur very quickly. Each noise meter was set up approximately 1.5 m above the ground and away from reflective objects. As stated above, the instruments were activated for a 24-hour period and collected at the end of the sample period. The raw noise data from each of the four units was downloaded to a computer. The logged data was then reduced to one hour Leq values for comparison with the Nova Scotia Guidelines for Environmental Noise Measurement and Assessment. (NSDE, 2005). The results of the monitoring program are provided in Section 4.3.7.
