    From Table 1, the following average ambient noise levels should be noted:

    o      LAeq,T:
                o     daytime:    52.2, 51.0, 50.1, 51.3, 50.6, 50.2                         Average = 50.9 dB(A);
                o     evening:    51.6, 51.9, 52.4, 51.0, 51.9, 49.7, 52.2                   Average = 51.5 dB(A);
                o     night-time: 47.9, 47.9, 47.8, 44.0, 46.9, 45.3, 47.8                   Average = 46.8 dB(A);

    o      LA1,T:
                o     daytime:    63.9, 63.2, 62.2, 64.5, 63.3, 62.7                         Average = 63.3 dB(A);
                o     evening:    59.2, 60.0, 60.9, 59.5, 60.6, 55.5, 57.9                   Average = 59.1 dB(A);
                o     night-time: 56.1, 55.5, 58.5, 55.4, 56.9, 55.0, 57.0                   Average = 56.3 dB(A);

    o      LA10,T:
                o     daytime:    52.7, 50.9, 50.4, 50.1, 48.8, 48.7                         Average = 50.3 dB(A);
                o     evening:    53.3, 53.2, 54.7, 53.0, 54.0, 51.8, 53.7                   Average = 53.4 dB(A);
                o     night-time: 49.6, 49.5, 50.7, 44.9, 50.3, 48.0, 50.4                   Average = 49.1 dB(A);

    o      LA90,T:
                o     daytime:    44.7, 42.1, 41.6, 41.7, 41.0, 40.5                         Average = 41.9 dB(A);
                o     evening:    47.7, 47.6, 47.1, 45.0, 46.0, 45.3, 47.7                   Average = 46.6 dB(A);
                o     night-time: 43.1, 44.0, 37.4, 35.6, 37.0, 36.0, 41.3                   Average = 39.2 dB(A).

    Based on the average background sound levels (LA90,T) the applicable noise limits are:

              daytime (0700 to 1800 hours):                  41.9 + 5 = 47 dB(A) LA10,adj,T;
              evening (1800 to 2200 hours):                  46.6 + 5 = 52 dB(A) LA10,adj,T;
              night-time (2200 to 0700 hours):               39.2 + 3 = 42 dB(A) LA10,adj,T.
