54 Elm Street and 5 Pearl Street, Cooroy                                                                      Page 17 of 36

For all of the private external living areas only the Unit 1 terrace requires an acoustic barrier to reduce
ultimate free field traffic noise levels by 5.4 dB(A). Refer to Noise Control section of this report for
further detail.

Traffic Noise – Level 1 Facades

In accordance with PO40, as the LA90,8H was less than 40 dB(A) the facade traffic noise limit is 60 dB(A)
LA10,18H facade corrected.

At the closest facade to Elm Street Table 6 details the ultimate facade corrected traffic noise level.

At the closest facade to Elm Street (western side wall of Unit 1) the ultimate facade corrected traffic
noise level exceeds the 60 dB(A) noise limit by 6.0 dB(A) LA10,18H.

At the next closest facade at right angles with Elm Street (rear wall of Unit 1) the ultimate facade
corrected traffic noise level will be as per Table 7.
