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 background noise levels the appropriate noise limits are:

Closest Residence to North-west

•   steady state noise: background + 0 dB(A): daytime = 53 dB(A) LA90,T;
                                              evening = 46 dB(A) LA90,T;
                                              night-time = 39 dB(A) LA90,T;

•   time varying noise: background + 5 dB(A): daytime = 58 dB(A) LAeq,adj,T;
                                              evening = 51 dB(A) LAeq,adj,T;
                                              night-time = 44 dB(A) LAeq,adj,T;

Closest Residences to North-east

•   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.

These are the noise limits that have been adopted in this report for noise from the subject site.


NOISE FROM SUBJECT SITE


On-Site Vehicle Noise

From previous noise level measurements conducted by the consultant, typical on-site vehicle noise
levels (time varying noise source) would be:

•   car driving on driveway:          46 dB(A) LAeq,adj,T @ 8 m;
•   car door closing:                 48 dB(A) LAeq,adj,T @ 30 m;
•   car engine starting:              48 dB(A) LAeq,adj,T @ 30 m.

At the closest adjoining residence to the north-west the only potential noise impact from on-site vehicle
activities is cars driving on the subject site driveway and car parking activities – engines starting and
doors closing. At this closest adjoining residence to the north-west these noise levels would be:

•   car driving on driveway:          46 dB(A) LAeq,adj,T @ 8 m – 2 (distance) = 44 dB(A) LAeq,adj,T;
•   car door closing:                 48 dB(A) LAeq,adj,T @ 30 m + 14 (distance) = 62 dB(A) LAeq,adj,T;
