Time Varying Noise
    car driving:                              50 dB(A) LAeq,adj,T @ 8 metres – 21 (90 m separation distance)
                                               – 12 (intervening commercial/industrial building) = 17 dB(A)
                                               LAeq,adj,T;

        car door closing:                     62 dB(A) LAeq,adj,T @ 8 metres – 21(90 m separation distance)
                                               – 12 (intervening commercial/industrial building) = 29 dB(A)
                                               LAeq,adj,T;

        car engine starting:                  62 dB(A) LAeq,adj,T @ 8 metres – 21(90 m separation distance)
                                               – 12 (intervening commercial/industrial building) = 29 dB(A)
                                               LAeq,adj,T;

        people laughing, talking:             62 dB(A) LAeq,adj,T @ 8 metres – 21(90 m separation distance)
                                               – 12 (intervening commercial/industrial building) = 29 dB(A)
                                               LAeq,adj,T;

        amplified music:                      85 to 90 dB(A) LAeq,adj,T @ 3 metres – 24 (45 m separation
                                               distance) – 25 (inside to outside building, external openings
                                               closed) = 36 to 41 dB(A) LAeq,adj,T;

        amplified voice:                      85 to 90 dB(A) LAeq,adj,T @ 3 metres – 24 (45 m separation
                                               distance) – 25 (inside to outside building, external openings
                                               closed) = 36 to 41 dB(A) LAeq,adj,T.

All of the above source noise levels comply (amplified music and amplified voice maximum permitted
volume is 89 dB(A) LAeq,adj,T) with the evening noise limits at the closest residence on the opposite side
of Walter Hay Drive. For noise from within the fitness centre – amplified music and amplified voice, this
assumes that all external openings are closed. As the fitness centre will be fully airconditioned there will
be no need to open any external doors or windows, albeit that it would appear that all windows are fixed
(unopenable) glazing. With respect to the sliding glass doors to the two mezzanine balconies, these are
both off office space and only accessible to fitness centre staff. These sliding glass doors must remain
closed whenever there is any noise generating activity within the fitness centre.

It should also be noted that one of the main potential sources of amplified music/voice is group fitness
activities, and this is conducted in a separate room with further noise attenuation to the closest
residences, as it is completely walled off from all other parts of the fitness centre (and this additional
acoustic isolation has net been accounted for in the above calculations).

Night-time

During the night-time (2200 to 0700 hours) the estimated lowest background sound level at the closest
residences is 40 dB(A), with associated noise limits of:

        steady sound:               30 dB(A) LA90,T;
        time varying sound:         35 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;
