Noise Limits

Based on the above and the fact that all of the closest residential are apartment buildings, the noise
limits which have been adopted in this report, for immediately outside a residential apartment, are as
described by Condition 81 of the Noosa Council approval for steady state noise and, for time varying
noise sources, as follows:

Steady State Noise Source

    daytime (0700 to 1900 hours):                         50 dB(A) LAeq,adj,T;
    evening (1900 to 2200 hours):                         43 dB(A) LAe,adj,T;
    night-time (2200 hours to midnight):                  38 dB(A) LAeq,adj,T.

Time Varying Noise Source

    daytime (0700 to 1800 hours):                         50 dB(A) LAeq,adj,T;
    evening (1800m to 2200 hours):                        45 dB(A) LAe,adj,T;
    night-time (2200 hours to midnight):                  40 dB(A) LAeq,adj,T.


AMBIENT NOISE LEVEL MEASUREMENTS

On Wednesday 13th November ambient noise levels were obtained from adjacent to Block 3, the closest
residential to the Facilities Building. The results of these ambient noise level measurements are
detailed in Table 1 below.
