2 Noise Monitoring

2.1      Noise Measurement Methodology
Noise measurements were taken continuously over a four-day period commencing Saturday 22nd
May to Wednesday 26th May 2021. The following information was detailed:
      ➢ Measurements were completed on the site using a Type 1 Sound Level Meter, Rion NL 54
        (s/n 00297846);
      ➢ The sound level meter holds current laboratory certificate of calibration, available upon
        request;
      ➢ The meter was calibrated before and after the measurements and was found to be within
        0.1dB of the reference signal;
      ➢ The meter records both slow and fast time weighted sound levels, along with statistics
        throughout the measurement period, allowing relevant data to be collected;
      ➢ The microphone was fitted with a standard wind screen;
      ➢ During the measurements, the microphone was located at a height of 1.4 metres above the
        ground level and at least 3 metres from reflecting facades (other than the ground plane); as
        such no adjustments have been applied for reflected noise.
Average meteorological conditions at the time, recorded at the Bureau of Meteorology’s Tewantin
site, were:
      ➢ Temperature:                   13.2 – 25.7oC
      ➢ Relative Humidity (avg):       81%
      ➢ Periods of rainfall omitted from the data.


2.2      Ambient Noise Monitoring
The results of the noise logging is summarised in Table 2.1. Figure 2.1 presents a chart of the
measured noise levels.
