Attachment 7 - Acoustic Report
8. Environmental Assessment
Noise associated with onsite activities has been assessed based on previous measurements of similar
activities. The calculations assume that the nominated activities are located at the closest
representative point to each receiver location. Any relevant shielding or building transmission loss is
taken into account for these activities.
8.1.1 Acoustic Quality Objectives
The average maximum noise source levels and predicted impacts at the receiver locations are shown
in Table 12. Note: LA10 and LA1 results are not shown in cases where the total duration of the events
is less than the minimum time required e.g. L A10(1hr) requires noise events to occur for at least 360
seconds of an hour long period. LAeq results are not shown where the calculated total is less than
0dBA.
