  Environmental Noise Level Impact Assessment for Proposed Addition of Second Floor to Block C and
  Associated Increase to Bed Numbers for Flashpackers, 102 and 106 Pacific Avenue, Sunshine Beach           Page 10 of 29




  From Table 1, the following average weekday and weekend background noise levels should be noted:

  Weekday, Monitoring Location A

  o      daytime:       53 dB(A) LA90,T;
  o      evening:       46 dB(A) LA90,T;
  o      night:         39 dB(A) LA90,T;

  Weekend, Monitoring Location B

  o      daytime:       47 dB(A) LA90,T;
  o      evening:       43 dB(A) LA90,T;
  o      night:         40 dB(A) LA90,T;

  Based on the above 2009 background noise levels the background creep noise limits for the closest
  adjoining residences to the north-east are:

  •      steady state noise: background + 0 dB(A): daytime = 47 dB(A) LA90,T;
                                                   evening = 43 dB(A) LA90,T;
                                                   night-time = 40 dB(A) LA90,T;

  •      time varying noise: background + 5 dB(A): daytime = 52 dB(A) LAeq,adj,T;
                                                   evening = 48 dB(A) LAeq,adj,T;
                                                   night-time = 45 dB(A) LAeq,adj,T.

  2018 Ambient Noise Assessment

  Table 2 details the results of the ambient noise level assessment from monitoring location C for a 7-
  day period in September 2018. For details of the measurement equipment, equipment settings,
  calibration, monitoring locations and atmospheric conditions, refer Appendix C. Appendix D details all
  of the results of the ambient noise level measurements.
