NOISE CONTROL

An acoustic barrier is required for the control of noise from vehicle activities, airconditioning units and
people (laughing and talking outside Manager’s Unit) on the subject site. 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 barrier calculated. The required location for the
acoustic barrier is as per Figure 4. This acoustic barrier must be a minimum 1.8 metres high relative
to current ground levels, be located as per Figure 4, be continuous and gap free and have a minimum
surface area density of 10 kg/m2. 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.

With the above acoustic barrier in place all potential noise sources associated with the proposed
extension of the backpacker accommodation will comply with the noise limits at the closest adjoining
residences to the north-east for the complete 24-hour day.
