objects. This predicted level would be most evident at the loading dock area of Noosa Civic. The indoor
level would readily be below the criteria of 45 dB(A), with sound reductions of 20 dB(A) expected
between the outside and inside of the Noosa Civic building structure.
The same calculation has been applied to the approved residential development to the east of the site on
Hoffmann Drive, also approximately 160 m away. The calculation is conservative as it doesn’t take into
account ground absorption or shielding. The predicted noise level (LAeq 1 hour) of a truck operating for 10
minutes in every hour at residences on Hoffmann Drive is 48 dB(A), which is below the criteria of 50
dB(A).

Other residential receivers exist 500 m to the west of the site on Gumdale Ct and Casuarina Ct. Noise
predictions at these receivers are highly conservative as many industrial buildings exist between the site
and the houses on Gumdale Ct and Casuarina Ct which would shield the noise. The predicted level (LAeq
1 hour) of truck noise during the day and evening time periods at houses on Gumdale Ct and Casuarina Ct

is 38 dB(A), which is below the criteria of 50 dB(A). This is likely to be masked by the ongoing ambient
noise associated with traffic on the Emu Mountain Road and Eumundi Road.


6.3         Risk of noise impact
Due to the separation distances between the proposal site and the nearest residential receivers (160 m -
500 m) and commercial receivers (160 m) the risk associated with noise impacts is very low. There are
other buildings between the site and residential receivers which will shield noise generated as part of
operations. There is a line of sight between the facility and the back of Noosa Civic, which supports the
loading docks for the shopping centre. Trucks in use at Noosa Civic would be similar or larger than those
used at the brewery, and of much higher throughput. Noise predictions in Section 6.2 show that the
expected noise levels from the site comply with the relevant criteria. This area is likely to also be
exposed to higher ambient noise associated with vehicle movements on Emu Mountain Road.

Noise levels at all sensitive receivers generated by the proposed development are expected to be below
the acoustic objectives outlined in the Environmental Protection (Noise) Policy 2008.


6.4         Noise assessment findings
Noise from the proposal is not considered to be an issue based on the proposal design and distance to
receivers for 24-hour operation. The use of masonry walls and the orientation of the building is
considered appropriate from an acoustic perspective with respect to the level of impact anticipated on
surrounding sensitive receivers.


7           Conclusion
A desktop odour and noise assessment has been undertaken for the proposed brewery at 85 Rene
Street. The assessment shows that odour and noise impacts will be negligible at all identified sensitive
receivers on the basis of the inclusion of specific design measures for managing odour emission from the
brewing process, and the setback of the facility from nearby noise sensitive premises.
