                       APPENDIX A: NOISE LEVEL MEASUREMENT EQUIPMENT


Measurement Equipment

The following equipment was used to conduct the ambient noise level measurements at the logger
monitoring location:

   Bruel and Kjaer Type 2260 Precision Sound Level Analyzer, Serial No. 2487423, with Type BZ
    7219, Version 1.2 Software and Prepolarised free-field ½” microphone, Type 4189, Serial No.
    2469624;

   Bruel and Kjaer Type 4231 Sound Level Calibrator, Serial No. 2292736.

All of the above equipment is Type 1 in accordance with the requirements of Australian Standard AS
1259-1990, Acoustics – Sound Level Meters.


Measurement Equipment Settings

The above equipment was used with the following settings:

   Detector:                       RMS
   Time Weighting:                 FAST
   Frequency Weighting:            linear in 1/3 octave bands from 20 to 20000 Hz
   Sound Incidence:                FRONTAL;
   Sensitivity:                    -28.4 dB.


Calibration

The sound level meter was calibrated to the required value of 93.8 dB at 1000 Hz immediately before
and after the noise level measurements were conducted. At no time was an adjustment of more than
0.5 dB required. This complies with the requirements of the Australian Standard.


Monitoring Location

Adjacent to the western boundary of the subject site closest to the closest adjoining residence to the
south-west, which is a similar setback distance from the proposed wave lagoon (and the ocean) as all
other closest residences to the west, with the microphone elevated approximately 1.6 m above the
ground level. Refer Figure 1 for further detail.


Atmospheric Conditions

Throughout the noise level assessment atmospheric conditions generally complied with the
requirements of the Australian Standard. Refer Appendix C for details.
