NOISE LIMITS

Based on the lowest of the above estimated background sound levels for the closest residences on the
opposite side of Walter Hay Drive, the ‘background creep’ noise limits for the proposed fitness centre
are:

Continuous noise:

        daytime (0700 to 1800 hours):                  40 dB(A) LA90,T;
        evening (1800 to 2200 hours):                  35 dB(A) LA90,T; and
        night-time (2200 to 0700 hours):               30 dB(A) LA90,T.

Time Varying noise:

        daytime (0700 to 1800 hours):                  45 dB(A) LAeq,adj,T;
        evening (1800 to 2200 hours):                  40 dB(A) LAeq,adj,T; and
        night-time (2200 to 0700 hours):               35 dB(A) LAeq,adj,T.


SOURCE NOISE LEVELS

From previous noise level measurements conducted by the consultant, typical source noise levels for a
Fitness Centre are:

        car driving:                          50 dB(A) LAeq,adj,T @ 8 metres;
        car door closing:                     62 dB(A) LAeq,adj,T @ 8 metres;
        car engine starting:                  62 dB(A) LAeq,adj,T @ 8 metres;
        people laughing, talking:             62 dB(A) LAeq,adj,T @ 8 metres;
        amplified music:                      85 to 90 dB(A) LAeq,adj,T @ 3 metres;
        amplified voice:                      85 to 90 dB(A) LAeq,adj,T @ 3 metres;
        airconditioning unit:                 68 dB(A) LWA.


NOISE LEVEL IMPACT

Daytime

During the daytime (0700 to 1800 hours) the estimated lowest background sound level at the closest
residences is 40 dB(A), with associated noise limits of:

        steady sound:               40 dB(A) LA90,T;
        time varying sound:         45 dB(A) LAeq,adj,T.

At the closest residences on the opposite side of Walter Hay Drive the noise level impact of the
proposed fitness centre will be:

Continuous Noise
    airconditioning unit:           68 dB(A) LWA + 5 (estimated 3 units, all operating) – 41 (45 m
                                     separation distance) – 5 (intervening acoustic barrier) = 27
                                     dB(A) LA90,T;
