            APPENDIX A: AMBIENT NOISE LEVEL MEASUREMENT EQUIPMENT, 2009


Measurement Equipment

The following equipment was used to conduct the two 24-hour ambient noise level studies, one at
Monitoring Location A and the other at Monitoring Location B:

•   Bruel and Kjaer Type 2260I Modular Precision Sound Analyzer – Observer – Serial No. 2409371,
    with Type BZ 7220 Software and Prepolarised free-field ½” microphone, Type 4189, Serial No.
    2395445;

•   Bruel and Kjaer Type 3592 outdoor microphone kit, including Type UA1404 outdoor microphone;

•   Bruel and Kjaer Type AO 0442 ten metre microphone extension cable; and

•   Bruel and Kjaer Type 4231 Sound Level Calibrator, Serial No. 2292746.

All of the above equipment is Type 1 in accordance with the requirements of Australian Standard AS
1259-1990, Acoustics – Sound Level Meters, as required by Australian Standard AS 1055.1-1997.


Measurement Equipment Settings

The above equipment was used with the following settings:

•   Detector:                        RMS
•   Time Weighting:                  FAST
•   Frequency Weighting:             A
•   Sound Incidence:                 FRONTAL
•   Microphone sensitivity:          -26.0 dB
•   Range:                           20-100 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

Monitoring Location A was on the Pacific Avenue boundary of the subject site, approximately 14
metres from the centre of traffic on Pacific Avenue with the microphone elevated 2.0 metres.

Monitoring location B was adjacent the rear boundary of the subject site with the microphone elevated
2 metres. Refer Figure 1 for further detail.


Atmospheric Conditions

Throughout the two 24-hour periods, atmospheric conditions complied with the requirements of the
Australian Standard.
