Flashpackers, 102 and 106 Pacific Avenue, Sunshine Beach                                                 Page 9 of 22




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.


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-east the primary potential noise impact is from the noise
of people, as the closest on-site vehicle activities – cars driving on the subject site driveway and car
parking activities – engines starting and doors closing, is adjacent to Pacific Avenue.
