Environmental Noise Level Impact Assessment for Proposed Expansion of Existing Backpacker
Accommodation onto 106 Pacific Avenue, Sunshine Beach                                                   Page 10 of 18




The noise limits for plant noise at the adjoining residences to the north-east are:

•   daytime:    47 dB(A);
•   evening:    43 dB(A);
•   night-time: 40 dB(A).

All of the above noise limits are complied with, with no additional noise control measures required.

Once the location and exact number of airconditioning units has been determined, and the
manufacturer and model number (and associated noise levels) selected, this information should be
provided to the acoustic consultant to re-assess the noise impact from the airconditioning units and, if
any of the noise limits are exceeded, nominate suitable noise control measures.


NOISE CONTROL

Acoustic barriers are required for the control of vehicle activities on the subject site, as well as the
noise of people laughing and talking in the covered communal area and outdoor DOSA, relative to the
adjoining residence to the north-west. The noise of airconditioning units requires further consideration
once their number and location has been determined, together with manufacturer and associated
noise levels.

With respect to the acoustic barrier requirements, path difference calculations have been performed
and the required extent and height of acoustic barriers calculated. With respect to the control of
vehicle activities the night-time period has not been considered as there are only two carparking
spaces in question and whilst they could be used at night, most of the activity will be during the
daytime and evening. It is also possible that these two carparking spaces could be signed that there
is to be no arrival/departure from these two spaces between the hours of 10pm and 7am daily. The
required acoustic barriers are:

    •    between the staff carparking space/driveway and the covered communal area and outdoor
         DOSA, 1.8 metres high and extending from the external wall of the cinema to the garden bad
         adjacent to pacific Avenue;

    •    corner (south-west) of the cinema to the north-western side boundary, then south-west on the
         north-western boundary to 3 metres from the Pacific Avenue boundary, 2.0 metres high. This
         acoustic barrier is approximately 7 metres long along the north-western side boundary.

The above acoustic barriers must be the nominated height relative to existing ground levels, be
located as per the above description and as indicated at Figure 4, be continuous and gap free and
have a minimum surface area density of 10 kg/m 2. Examples of suitable materials of construction
include, but are not limited to:

    •   reinforced concrete;
    •   concrete block;
    •   brick;
    •   hebel panel;
    •   sheet metal at least 2 mm thick;
    •   minimum 7.5 mm thick fibrous cement sheet;
    •   earth mound;
    •   lapped timber palings, for example, kiln dried softwood palings at least 19 mm thick and
        overlapped a minimum 20 mm;
    •   any combination of the above.
