   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 appropriate 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.
