4            Measurements
4.1            Equipment
The following equipment was used to measure existing noise levels:

         •     ARL EL 316 Environmental noise logger (SN# 16-707-016)

         •     Norsonic 140 Environmental noise logger (SN# 1406507)

         •     Norsonic 131 Sound Level Meter (SN# 1313158)

         •     RION NC-73 Sound Calibrator (SN# TTMNC73-01)

All equipment was calibrated by a National Association of Testing Authorities (NATA) accredited laboratory.
The equipment was field calibrated before and after the measurement session. No significant drift from the
reference signal was recorded.

4.2            Unattended Noise Monitoring
Unattended noise monitoring was conducted between Thursday 23rd and Thursday 30th March 2023 to
establish the existing ambient noise levels at the site location and nearest residential receivers. The noise
monitoring locations are shown in Figure 3. The ambient monitors were in a position considered
representative of the ambient noise levels experienced at the site and surrounding locations with
consideration to both access and equipment security requirements.

The microphones were in free-field locations and 1.5m above ground level. The noise monitors were 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
with approx. 2mm of rain on the 29th of March and no / negligible rainfall on all other days. Rainfall affected
data was excluded from the analysis (source: Bureau of Meteorology).
