6.2. Mechanical Plant Noise
In accordance with the Sunshine Coast Regional Council requirement for the application of the
background creep policy, the following criteria shall apply that mechanical plant does not exceed
the existing background noise levels by more than 0dB(A). Based upon measured background
noise levels measured at the site, the following noise limits apply to mechanical plant when
measured at the property boundary of affected residents.

                                 Table 3: Criteria for Residential Receivers.

         Time Period                                          Criteria LA90 dB(A)
         Daytime 7am – 6pm                                   46 (LA90 + 0 dB(A))
         Evening – time 6pm – 10pm                           41 (LA90 + 0 dB(A))
         Night time 10pm – 7am             35 internal (Sleep disturbance criteria Section 6.1.2)

Refer to Appendix B for graphical representation of measured noise levels.

The above levels are quoted as a measured level, not a component level; hence, all plant
proposed must be included in assessment including correction for tonality. By designing plant
noise to a measured level rather than a component level, the additive effect of multiple plant is
taken into account.
