 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. For the 2018 report the background creep criteria was adopted as the most
     appropriate noise limit criteria. This is the criteria which has also 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.
