5 DISCUSSION 5.1 Noted Noise Sources Table 4.1 to Table 4.4 present data gathered during attended monitoring. These noise levels are the result of many sounds reaching the sound level meter microphone during monitoring. Received levels from various noise sources were noted during attended monitoring and particular attention was paid to the extent of Mangoola Coal’s contribution, if any, to measured levels. At each receptor location, Mangoola Coal’s L Aeq(15 minute) (in the absence of any other noise) was, where possible, measured directly, or, determined by frequency analysis. From these observations summaries have been derived for each location. The following report sections provide these summaries. Statistical 1/3 octave band analysis of environmental noise was undertaken, and the charts following in this section display the frequency ranges for various noise sources at each location for L A1, L A10 , L A90 , and L Aeq . These figures also provide, graphically, statistical information for these noise levels. An example is provided as Figure 2 where it can be seen that frogs and insects are generating noise at frequencies above 1000 Hz; mining noise is at frequencies less than 1000 Hz (this is typical). Adding levels at frequencies that relate to mining only allows separate statistical results to be calculated. This analysis cannot always be performed if there are significant levels of other noise at the same frequencies as mining; this can be dogs, cows, or, most commonly, road traffic. It should be noted that the method of summing statistical values up to a cut-off frequency can overstate the L A1 result by a small margin but is entirely accurate for L Aeq . 19 12324_R01.doc Page 19
