Noosa Civic - Acoustic Review of Proposed Fence

Acoustic Logic has been asked to provide comments on the proposed acoustic fence between Noosa Civic
Shopping Centre and the proposed residential lots.

Noise impacts from the general activities have been predicted and recommendations for the residential
façade constructions as well as the noise barrier have been provided in Acoustic Logic report Noosa Civic
Noise Impact Assessment (ref: 20191414.2/0309A/R4/OB, dated 3/09/2020).

We have reviewed the proposed location indicated below and note that the location indicated with red
dashed line is generally in accordance to the proposed location in the above-mentioned report Section 6.2
for lots 19 and 21. Lot 17 is not indicated and therefore, it is not addressed in this letter.

We also confirm that in accordance to the report, the timber fence is required to be 1800mm from above
the loading dock ground level or top of existing loading dock blockwork whichever is higher. On the proviso
that this is achieved, the height of the proposed barrier follows the recommendations in Section 6.2 of the
abovementioned report.

Lastly, it is a requirement to construct the fence gap free and have it built from materials to achieve a
minimum surface density of 12kg/m2.

We understand that 100mmx25mm thick timber palings are used for the fence. Without exact information
on the weight, we have assumed radiate pine average 400kg/m3 density to determine if the construction is
capable of achieving the requested surface density. With the assumed density, the 25mm thick palings are
capable of achieving approximately 10kg/m2, however, given the palings are lapped with min 20mm overlap
as indicated below, approximate 40% weight increase is predicted to occur per linear metre which in turn
leads to average of 14kg/m2 surface density. We note that this is a nominal outcome and the actual minimum
surface density of 12kg/m2 must be achieved by the contractor by selecting appropriate materials and
construction techniques.
