Environmental Noise Level Impact Assessment for Proposed Expansion of Existing Backpacker
Accommodation onto 106 Pacific Avenue, Sunshine Beach                                                   Page 12 of 18




The 2.0 metre high acoustic barrier will reduce vehicle activity noise levels, at the closest adjoining
residence to the north-west, by approximately 9 dB(A), which will result in compliance with the daytime
noise limit and a 2 dB(A) exceedance of the evening noise limit. As, subjectively, a change in noise
level of 1 to 2 dB(A) is not perceivable to the human ear, this 2 dB(A) evening noise limit exceedance
will sound the same at the closest adjoining residence to the north-west and, there, should be deemed
to comply with the evening noise limit.


CONCLUSIONS

The existing backpacker accommodation located at 102 Pacific Avenue, Sunshine Beach, for which
David Moore & Associates Pty Ltd prepared the original noise report for in 2009, is proposed to be
extended onto 106 Pacific Avenue. The existing dwelling is to remain on site and undergo some
minor alterations to be suitable for the proposed backpacker accommodation. In accordance with
advice from Nadine Gorton, Town Planner, Noosa Council have requested a noise impact assessment
be prepared for this proposed expansion of the backpacker accommodation.

This report has been based on the noise criteria contained in the Environmental Protection (Noise)
Policy 2008 and the adopted background sound levels based on the results of the 2009 ambient noise
assessments. It is the opinion of the acoustic consultant that these 2009 background sound levels are
still relevant today, albeit that they are most likely conservative as the primary noise source in this
area is traffic on Pacific Avenue, which is a direct link between the David Low Way and Noosa Heads
and carries a significant volume of traffic.

Pacific Avenue is not a transport noise corridor and as the existing residence is not being replaced or
extended traffic noise impact does not require consideration.

Potential noise impacts from the proposed extension to the backpacker accommodation onto 106
Pacific Avenue could include vehicle activities (cars driving, car doors closing and car engines
starting), people laughing and talking and plant and equipment (airconditioning units). The 2009
background sound levels were used to determine the noise limits in accordance with the ‘background
creep’ criteria, for the closest adjoining residence to the north-west, as well as the adjoining
residences to the north-east. Source noise levels were based on previous assessments conducted by
the consultant of similar premises.

With the acoustic barriers nominated in Figure 4 in place the noise of on-site vehicle activities
complies/effectively complies with the daytime and evening noise limit criteria and the noise of people
laughing and talking complies with the noise limit criteria 24-hours per day. With respect to night-time
vehicle activity, this is not likely to occur very often and this assessment only relates to two carparking
spaces. Therefore any potential night-time noise impact would be minimal and, additionally, these two
carparking bays could be signed that no vehicle is to arrive into or depart from either of these
carparking bays between the hours of 10pm and 7am daily.

With respect to the noise impact from plant and equipment (airconditioning units) the number, noise
level and location of these units has been assumed and calculated to the closest adjoining residences.
Whilst the noise limits are complied with at the closest residences to the north-east, airconditioning
unit noise levels, particularly those units associated with the dorms, exceed the night-time noise limit.

To ensure compliance with the noise limits for 24-hours per day, 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.
