  Environmental Noise Level Impact Assessment for Proposed Expansion of Existing Backpacker

  2. Background Creep.

       The ‘background creep’ noise limit criteria is specifically designed to adequately account from the
       additive effect of a number of different noise sources, which can be generated by a number of
       different premises. As there is an existing backpacker accommodation at 102 Pacific Avenue and
       it is proposed to extend this onto the subject site at 106 Pacific Avenue, background creep is
       considered the most appropriate noise limit criteria. This is the criteria which has been adopted in
       this report.

            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
                                        LA90,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
                                        LA90,T.


  AMBIENT NOISE LEVELS

  2009 Ambient Noise Assessments

  Table 1 details the results of the ambient noise level assessments from monitoring location A during
  the week and over the weekend for monitoring location B, in 2009. For details of the measurement
  equipment, equipment settings, calibration, monitoring locations and atmospheric conditions, refer
  Appendix A. Appendix B details all of the results of the ambient noise level measurements.
