Noise Report

The microphone was in a free-field location and 1.5m above ground level. The noise monitor was set to
measure statistical noise levels in 'A'-weighting, 'Fast' response, over 15 minute intervals. Ambient noise
levels were measured in accordance with Australian Standard AS1055:2018 Acoustics – Description and
Measurement of Environmental Noise (AS1055). Weather during the monitoring period was generally fine
(source: Bureau of Meteorology).

4.3             Noise Source Measurements
Noise levels associated with typical on-site activities were taken from similar investigations conducted by
TTM. All measurements were conducted generally in accordance with AS1055.

4.4             Results of Measurements
4.4.1           Ambient Noise Levels
Table 1 presents the measured ambient noise levels. The Rating Background Level (RBL) is an average
minimum background noise level (10th percentile average) in accordance with planning scheme
requirements. Graphical presentation of the measured levels is shown in Appendix B. The measurement
results were used to determine the assessment criteria for the development.
