  From Table 2, the following average ambient noise levels should be noted:

  o      LAeq,T:
              o     daytime:    49.4, 48.9, 49.8, 49.2, 48.5, 48.1, 52.3      Average = 49.6 dB(A);
              o     evening:    44.8, 46.5, 44.3, 53.1, 44.4, 52.7, 45.9      Average = 47.4 dB(A);
              o     night-time: 42.0, 43.7, 41.4, 43.1, 43.2, 42.2, 43.6      Average = 42.7 dB(A);

  o      LA1,T:
              o     daytime:    58.4, 57.2, 58.6, 59.0, 57.7, 57.2, 63.1      Average = 58.7 dB(A);
              o     evening:    53.4, 55.9, 52.8, 57.7, 53.1, 57.7, 53.5      Average = 54.9 dB(A);
              o     night-time: 50.9, 51.4, 49.8, 52.4, 52.6, 52.5, 52.7      Average = 51.8 dB(A);

  o      LA10,T:
              o     daytime:    51.3, 51.1, 51.5, 51.9, 51.1, 50.7, 56.1      Average = 52.0 dB(A);
              o     evening:    47.4, 48.5, 46.9, 55.7, 46.8, 55.1, 48.3      Average = 49.8 dB(A);
              o     night-time: 44.3, 45.5, 44.1, 45.3, 45.4, 44.3, 45.8      Average = 45.0 dB(A);

  o      LA90,T:
              o     daytime:    42.1, 43.6, 43.9, 41.0, 41.8, 41.3, 43.2      Average = 42.4 dB(A);
              o     evening:    37.7, 40.6, 38.4, 47.5, 37.9, 46.9, 41.2      Average = 41.6 dB(A);
              o     night-time: 36.8, 38.3, 35.2, 37.0, 36.7, 35.6, 37.5      Average = 36.7 dB(A).

  Based on the above 2018 background noise levels the background creep noise limits are:

  Closest Residences to North-east

  •      steady state noise: background + 0 dB(A): daytime = 42 dB(A) LA90,T;
                                                   evening = 42 dB(A) LA90,T;
                                                   night-time = 37 dB(A) LA90,T;

  •      time varying noise: background + 5 dB(A): daytime = 47 dB(A) LAeq,adj,T;
                                                   evening = 47 dB(A) LAeq,adj,T;
                                                   night-time = 42 dB(A) LAeq,adj,T.

  As the 2018 ambient noise assessment has resulted in lower noise limit criteria than the 2009
  assessment the above 2018 background creep noise limits are the noise limits that have been
  adopted in this report for noise from the subject site.
