5. Measured Noise Levels
The following tables present the measured ambient noise levels from the unattended noise surveys
and meteorological conditions. Any periods of inclement weather or extraneous noise were omitted
from the measured data prior to determining the results.


5.1   Meteorological Conditions
Meteorological observations during the unattended noise monitoring survey were obtained from the
Bureau of Meteorology website (http://www.bom.gov.au/climate/data), shown in Table 1 below.

*Note extraneous noise on the 30th March and 3rd and 4th April was found to affect the
measurements, therefore the data was omitted for the affected time periods.

Based on detailed review of the noise data, the evening period was found to be affected by insect
noise on the days nominated in Table 2 and above.
