Environmental Noise Level Impact Assessment for Proposed Expansion of Existing Backpacker
Accommodation onto 106 Pacific Avenue, Sunshine Beach                                                    Page 9 of 18




At the closest adjoining residence to the north-west the noise of people laughing and talking would be:

•   covered communal area:           54 dB(A) LAeq,adj,T @ 8 m – 4 (distance) – 8 (acoustic barrier/fence
                                     between communal area and staff carparking space = 42 dB(A);

•   outdoor DOSA:                    54 dB(A) LAeq,adj,T @ 8 m – 5 (distance) – 8 (acoustic barrier/fence
                                     between outdoor DOSA and staff carparking space = 41 dB(A).

The noise limits for the above noise source, at the adjoining residence to the north-west, are:

•   daytime:    58 dB(A) LAeq,adj,T;
•   evening:    51 dB(A) LAeq,adj,T;
•   night-time: 44 dB(A) LAeq,adj,T.

All of the above noise limits are complied with for the complete 24-hour day, provided the fence
between the communal area and DOSA and the staff carparking space is an acoustic barrier.


Plant Noise

Plant noise from the proposed backpacker accommodation could include airconditioning units. Whilst
at the time of preparing this report no detail was available with respect to plant it has been assumed
that the 6-bed Dorms would be airconditioned, along with the Manager and Staff facilities and the
cinema. Based on previous noise assessments conducted by the consultant typical airconditioner
noise levels are 64 dB(A) LWA.

At the closest adjoining residence to the north-west the noise level of the airconditioning units,
assuming a total of 6 units (dorms × 3, cinema × 1, staff/manager × 2) would be:

•   dorms:                  64 dB(A) LWA + 6 (3 units) – 26 (distance) = 44 dB(A);
•   cinema:                 64 dB(A) LWA – 30 (distance) – 8 (fence/barrier between communal area and
                            staff carpark) = 26 dB(A);
•   staff:                  64 dB(A) LWA + 3 (2 units) – 30 (distance) = 37 dB(A);
•   combined:               44 + 26 + 37 = 45 dB(A) LA90,T.

The noise limits for plant noise at the adjoining residence to the north-west are:

•   daytime:    53 dB(A);
•   evening:    46 dB(A);
•   night-time: 39 dB(A).

The night-time noise limit is exceeded by the three airconditioning units associated with the Dorms.
Therefore, if the Dorms are to be airconditioned, EITHER the airconditioning units need to be located
remote from the adjoining residence to the north-west OR these airconditioning units are acoustically
treated with an acoustic enclosure OR acoustic barrier on the common boundary adjacent to these
airconditioning units.

At the closest adjoining residences to the north-east the noise level of the airconditioning units,
assuming a total of 6 units (dorms × 3, cinema × 1, staff/manager × 2) would be:

•   dorms:                  64 dB(A) LWA + 6 (3 units) – 36 (distance) = 34 dB(A);
•   cinema:                 64 dB(A) LWA – 38 (distance) – 15 (intervening building) = 11 dB(A);
•   staff:                  64 dB(A) LWA + 3 (2 units) – 32 (distance) = 35 dB(A);
•   combined:               34 + 11 + 35 = 38 dB(A) LA90,T.
