                   APPENDIX C: NOISE LEVEL MEASUREMENT EQUIPMENT, 2018

Measurement Equipment

The following equipment was used to conduct the ambient noise level study at Monitoring Location C:

•   Bruel and Kjaer Type 2250 L Hand Held Analyzer – Serial No. 3004242, with Type BZ 7131, BZ
    7132 and BZ 7133 Software and Prepolarised free-field ½” microphone, Type 4189, Serial No.
    2879996;

•   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. 2292736.

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:           39.216 mV/Pa


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 C was approximately 1 metre inside the north-east boundary of 106 Pacific
Avenue, Sunshine Beach, immediately adjacent to the side boundary with 102 Pacific Avenue, on the
subject site, with the microphone elevated 1.6 metres above ground level. Refer Figure 1 for further
detail.


Atmospheric Conditions

Throughout the 7-day ambient noise assessment atmospheric conditions complied with the
requirements of the Australian Standard.
