Noosa Quad Bike Tours
Environmental Noise Level Assessment of Quad Bike Rider Competency Assessment Circuit,
298 Tablelands Road, Cooran                                                                             Page 5 of 11




For the daytime operation of the quad bikes on the test/training circuit the noise limit at the nearby
residences is 38 dB(A), expressed as the LA10,adj,T. Based on the above calculations this noise limit is
complied with at all of the closest residences to the test/training circuit for the quad bikes, with twelve
quad bikes all using the test/training circuit at the same time.


CONCLUSIONS


Prior to allowing participants out on public roads, Noosa Quad Bike Tours intend to conduct a
competency assessment of riders on a test/training circuit at their property at 298 Tablelands Road,
Cooran. Up to 12 quad bikes will be involved in each tour and, therefore, there could be up to 12 quad
bikes on the test/training circuit. This test/training ’circuit’ is located approximately 70 metres down a
steep decline from Tablelands Road in a gully, on the eastern side of Tablelands Road with the
closest residential being approximately:


    .     350 m to the north-west, opposite side of Tablelands Road;
          350 m to the west, opposite side of Tablelands Road;
    .     250 m to the south, opposite side of Tablelands Road; and
          400 m to the south-east, same side of Tablelands Road.


Sunshine Coast Regional Council have requested Noosa Quad Bike Tours to conduct a noise
assessment of the quad bikes using the test/training circuit at 298 Tablelands Road, Cooran, for up to
12 quad bikes, to determine noise impact at all of the nearby residences (located as per Figure 1).


On Wednesday 18 April 2012 David Moore & Associates Pty Ltd conducted a noise assessment of the
quad bike to be used for the tours, namely a Kymco MXU 300 quad bike with automatic transmission
and a 270cc engine. This assessment was conducted with the quad bike being ridden around the
test/training circuit, together with a background noise assessment.

From the background noise assessment the daytime noise limit was determined, and from the results
of one quad bike riding around the circuit the noise level of 12 quad bikes on the circuit was calculated
to all of the closest residences. Based on the daytime background sound levels the noise limit at
these residences is 38 dB(A), and this was complied with at all of the closest residences.


As the noise limit is complied with, no noise control measures are required for the Noosa Quad Bike
Tours test/training circuit at 298 Tablelands Road, Cooran, for daytime use for up to 12 quad bikes at
a time.




RECOMMENDATION


It is recommended that the quad bike test/training circuit at 298 Tablelands Road, Cooran be
approved, with no noise control measures required.
