Environmental Noise Level Study for Proposed Service Station and Fast Food Premises, 6 Taylor Court, Cooroy   Page 7 of 15




NOISE LEVEL IMPACT

The closest residences to the proposed service station and associated shop and fast food premises are:

   west, on the eastern side of Ferrells Road, approximately 450 metres;
   east on the northern side of Nandroya Road, approximately 360 metres;
   south-west on the eastern side of Ferrells Road, approximately 430 metres.

All other residences are set back further than the above residences. Compliance with the noise limits at
the above closest residences would also result in compliance with the noise limits at all other residential
premises.

Detailed below is the noise level impact to the closest residences to the west, east and south-west.


Closest Residence to West

At the closest residence to the west, on the eastern side of Ferrells Road, the noise level impact of the
different noise sources are:

   forecourt activities:             50 dB(A) LAeq,adj,1hr @ 15 m – 30 (distance) = 20 dB(A);
                                      60 dB(A) LA1,adj,1hr @ 15 m – 30 = 30 dB(A);
                                      53 dB(A) LA10,adj,1hr @ 15 m – 30 = 23 dB(A);

   fuel delivery:                    72 dB(A) LAeq,adj,1hr @ 3 m – 44 (distance) = 28 dB(A);
                                      80 dB(A) LA1,adj,1hr @ 3 m – 44 = 36 dB(A);
                                      76 dB(A) LA10,adj,1hr @ 3 m – 44 = 32 dB(A);

   plant and equipment:              53.5 dB(A) LAeq,adj,1hr @ 10 m – 33 (distance) = 21 dB(A);
                                      56.5 dB(A) LA1,adj,1hr @ 10 m – 33 = 24 dB(A);
                                      54.5 dB(A) LA10,adj,1hr @ 10 m – 33 = 22 dB(A);

   general:
       o delivery truck:                        65 dB(A) LAeq,adj,T @ 6 m – 38 (distance) = 27 dB(A);
                                                70 dB(A) LA1,adj,T @ 6 m – 38 = 32 dB(A);
                                                67 dB(A) LA10,adj,T @ 6 m – 38 = 29 dB(A);

         o    waste collection:                 70 dB(A) LAeq,adj,T @ 8 m – 35 (distance) = 35 dB(A);
                                                74 dB(A) LA1,adj,T @ 8 m – 35 = 39 dB(A);
                                                72 dB(A) LA10,adj,T @ 8 m – 35 = 37 dB(A).

At the closest residence to the west, with no noise control measures in place, the daytime, evening and
night-time noise limits of 47, 52 and 42 dB(A) LA10,adj,T respectively are all complied with. Therefore, for
the closest residence to the west, no additional noise control measures are required.


Closest Residence to East

At the closest residence to the east, on the northern side of Nandroya Road, the noise level impact of
the different noise sources are:

   forecourt activities:             50 dB(A) LAeq,adj,1hr @ 15 m – 28 (distance) = 22 dB(A);
                                      60 dB(A) LA1,adj,1hr @ 15 m – 28 = 32 dB(A);
                                      53 dB(A) LA10,adj,1hr @ 15 m – 28 = 25 dB(A);

   fuel delivery:                    72 dB(A) LAeq,adj,1hr @ 3 m – 42 (distance) = 30 dB(A);
                                      80 dB(A) LA1,adj,1hr @ 3 m – 42 = 38 dB(A);
                                      76 dB(A) LA10,adj,1hr @ 3 m – 42 = 34 dB(A);
