3 Measurements

                     Noise measurements were carried out at the site from 1 September 2015 to 8
                     December 2015 at the location shown in Figure 3.
                     The measurements were carried out using a Rion NL-21 (serial no. 351) recording
                     “fast” response A-weighted sound levels at 15-minute intervals, with the
                     microphone at a height of approximately 1.2 m. Weather data for the duration of
                     the survey was obtained from the Bureau of Meteorology automatic weather
                     station at Noosa, and conditions were generally fine and suitable for noise
                     monitoring. The instrument was checked for calibration prior to and post-
                     measurement using a 94 dB acoustic signal at 1000 Hz, and drift in calibration was
                     nil.
                     The site was attended for a 15-minute period on 8 September 2015 to gain a
                     subjective assessment of the acoustic environment and to verify that the sound
                     measurement instrumentation was functioning correctly.
                     Notes from the attended measurements are provided in Table 1, and a summary
                     of the logged data over the week is provided in Table 2. A graphical representation
                     of the measurement data is provided in Appendix B.
