Environmental Noise Level Impact Assessment for Proposed Increase to Bed Numbers for
Flashpackers, 102 and 106 Pacific Avenue, Sunshine Beach                                                Page 10 of 22




For the closest adjoining residences to the north-east, with no additional noise control measures in
place, vehicle noise level impact would be:

•   car driving on driveway:         46 dB(A) LAeq,adj,T @ 8 m – 12 (distance) = 34 dB(A) LAeq,adj,T;
•   car door closing:                48 dB(A) LAeq,adj,T @ 30 m – 1 (distance) = 47 dB(A) LAeq,adj,T;
•   car engine starting:             48 dB(A) LAeq,adj,T @ 30 m – 1 (distance) = 47 dB(A) LAeq,adj,T.

The noise limits for the above noise sources, at the adjoining residences to the north-east, are:

    •    daytime:           47 dB(A) LAeq,adj,T;
    •    evening:           47 dB(A) LAeq,adj,T;
    •    night-time:        42 dB(A) LAeq,adj,T.

With no noise control measures in place these noise limits are exceeded by:

    •    daytime:           0 dB(A) LAeq,adj,T;
    •    evening:           0 dB(A) LAeq,adj,T;
    •    night-time:        5 dB(A) LAeq,adj,T.

As the night-time noise limit criteria was exceeded a 1.8 metre high acoustic barrier was constructed
to control this noise source to the noise limits for the complete 24-hour day – refer Figure 1 for the
location of this acoustic barrier.


People Laughing and Talking

In the 2018 report the following source noise level was used for people laughing and talking:

•   people laughing and talking:               54 dB(A) LAeq,adj,T @ 8 metres.

Based on the capacity of Flashpackers increasing by 11 guests the above source noise level would
increase by 1 dB(A) to 55 dB(A) LAeq,adj,T.

The primary areas where guests would be laughing and talking would be in the (covered) communal
area and the outdoor communal area, adjacent to Pacific Avenue, and the pool and deck adjacent to
the pool.

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

•   covered communal area:           55 dB(A) LAeq,adj,T @ 8 m – 12 (distance) – 8 (barrier effect of
                                     backpacker accommodation building and/or acoustic barrier) = 35
                                     dB(A) LAeq,adj,.T;

•   outdoor area:                    55 dB(A) LAeq,adj,T @ 8 m – 13 (distance) – 8 (barrier effect of
                                     backpacker accommodation building and/or acoustic barrier) = 34
                                     dB(A) LAeq,adj,T;

•   pool and deck:                   55 dB(A) LAeq,adj,T @ 8 m – 8 (distance) – 12 (barrier effect of
                                     backpacker accommodation building and/or acoustic barrier) = 35
                                     dB(A) LAeq,adj,T;

The noise limits for the above noise source, at the adjoining residences to the north-east, are:

•   daytime:    47 dB(A) LAeq,adj,T;
•   evening:    47 dB(A) LAeq,adj,T;
•   night-time: 42 dB(A) LAeq,adj,T.
