CRITERIA

Measurements and Calculations

All previous background sound level measurements (associated with other projects within Noosa
Council) were conducted in accordance with the following:

    general requirements of the Queensland environmental protection legislation;
    Environmental Protection (Noise) Policy 2008;
    Noise Measurement Manual, Queensland Government – Environmental Protection Agency, Version
     4, August 2013; and
    Australian Standard AS 1055.1-1997, Acoustics – Description and Measurement of Environmental
     Noise, Part 1, General Procedures.

Noise Limits

The closest residences are to the east on the opposite side of Walter Hay Drive and are exposed to a
number of different potential noise sources associated with the commercial/industrial buildings located
at 8 Selkirk Drive, Noosaville and, therefore, the most appropriate noise limit criteria is the ‘background
creep’ criteria of the Environmental Protection (Noise) Policy 2008, namely:

10       Controlling Background Creep

         (1)       This section states the management intent for an activity involving noise.

         (2)       To the extent that it is reasonable to do so, noise from an activity must not be –

                   (a)      for noise that is continuous noise measured by LA90,T – more than nil dB(A)
                            greater than the existing acoustic environment measured by L A90,T; or

                   (b)      for noise that varies over time measured by LAeq,adj,T – more than 5 dB(A)
                            greater than the existing acoustic environment measured by L A90,T.

The ‘background creep’ noise limit criteria is specifically designed to adequately account for the additive
effect of a number of different noise sources, which can be generated by a number of different
premises.


BACKGROUND SOUND LEVELS

From background sound level measurements conducted for other projects within the Noosa Council
area the estimated background sound levels at the closest residences to the east of the proposed
fitness centre are:

        daytime:           40 to 45 dB(A) LA90,T;
        evening:           35 to 40 dB(A) LA90,T; and
        night-time:        30 to 35 dB(A) LA90,T.

To be conservative the adopted background sound levels for the different time periods are the lowest of
the above range of levels.
