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 84 dB(A) LAeq,adj,T) with the night-time noise limits at the closest residence on the opposite side
of Walter Hay Drive. Also, for the night-time period (2200 to 0700 hours), it is not considered likely that
there would be any amplified music (other than quiet background music) or amplified voice.

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).


NOISE CONTROL

All potential noise sources associated with carparking activities and airconditioning units comply with the
noise limit criteria for the complete 24-hour day, with no noise control measures required.

For noise from within the fitness centre, provided all external openings are closed and the noise level of
amplified music/amplified voice does not exceed the following levels:

        daytime:           94 dB(A) LAeq,adj,T @ 3 metres from the speakers;
        evening:           89 dB(A) LAeq,adj,T @ 3 metres from the speakers; and
        night-time:        84 dB(A) LAeq,adj,T @ 3 metres from the speakers.

then the noise limits are complied with at the closest residential (on the opposite side of Walter Hay
Drive) for the complete 24-hour day.
