3.           Methodology
3.1          Measurement Equipment
The following equipment was used to measure existing noise levels:
             Five ARL EL316 Environmental Noise Loggers (serial numbers 16-306-005, 16-207-011,
              16-306-012, 16-707-010 and 16-004-037);
             BSWA Technology Co. Ltd Sound Calibrator (Serial number 44095);
             RION NA-28 Sound Level Meter (Serial number 01060055);
             RION NC-74 Sound Calibrator (Serial number 35073393).

Equipment was calibrated by a NATA accredited laboratory. Certification is held and available on
request. Instrument calibration was checked before and after the monitoring sessions with no
significant drift from the reference signal.


3.2          Unattended Noise Monitoring
The individual residences surrounding the site are believed to be experiencing differing ambient
noise levels. This is due to the proximity of the surrounding road network and existing
commercial/retail activities. As a result two unattended ambient noise monitoring locations were
selected to obtain an accurate representation of the ambient noise levels for residential receivers
surrounding the site. The unattended noise monitoring locations are shown in Figure 3.


3.2.1        ‘A’ Weighted – Unattended Ambient Noise Measurements
ARL EL316 noise monitors were located in the front yard of 7 Coral Tree Avenue and in the front
yard of 22 Wyandra Street. The microphones were in free field locations, approximately 1.4
metres above ground surface level. The locations were selected as they are representative of
ambient noise levels experienced by existing residents.

The noise monitors were set to measure noise levels from the 21st to the 30th of November, 2012
as follows:

             ‘A’ weighting;
             ‘Fast’ response; and
             15 minute statistical interval.
Measurements were conducted generally in accordance with Australian Standard AS1055:1997
Acoustics – Description & Measurement of Environmental Noise.
