4.2     Offsite Sources
To ensure a reasonable acoustic amenity is maintained for the proposed development, the nearest
offsite activities were considered as shown in Figure 2. The nearest offsite sources were identified
as follows:

        A. Single storey commercial premises (restaurants) along the southern site boundary of the
           site. Assumed operating hours of the various restaurants operate between 7am and
           Midnight (according to Google Maps).
        B. Commercial premises located at 4 Bottlebrush Avenue.


4.3     Unattended Noise Monitoring
4.3.1    Road Traffic Noise Levels
A Rion NL42 environmental noise monitor was placed at 71 Noosa Drive, 12m from the nearest lane
to measure road traffic and ambient noise levels. The monitor was located in a free field position
with the microphone approximately 1.4 metres above ground surface level. The noise monitor was
set to record noise levels between the 18 and 25 May 2023.

The environmental noise monitor was set to record noise levels in “A” Weighting, Fast response
using 15-minute statistical intervals. Ambient noise monitoring was conducted generally in
accordance with Australian Standard AS1055:2018 ‘Acoustics – Description and measurement of
environmental noise’. Refer to Figure 2 for noise monitoring location.

4.4     Attended Monitoring
4.4.1    Road Traffic Noise
In addition to the unattended noise monitoring, attended noise measurements of the Noosa Drive
were conducted on 25th May 2023. The Norsonic Nor140 Sound Level Meter was located
approximately 3 m from the Noosa Drive with the microphone positioned 1.5 metres above ground
level. Noise measurements were conducted in “A” weighting “Fast” response, 15 minute statistical
interval which recorded the LA10 (used to calculate the 18 hour LA10).

For the attended and unattended noise monitoring locations refer to Figure 2.


4.4.2    Offsite Activities
Attended measurements were conducted on the 25th May 2023 to determine the noise impacts
associated with the offsite activities. The assessed activities are associated with any offsite activity
including mechanical plant units which may impact the site, with the results presented in Section
5.2.

The noise measurements were conducted utilising a Norsonic NOR140 sound level meter measured
in 1/3 octave bands. All noise measurements were conducted generally in accordance with Australian
Standard AS1055 'Acoustics – Description & Measurement of Environmental Noise'.
