Noise Level Assessment Report for Noosa Quad Bike Tours MCU12/0012

Noosa Quad Bike Tours
Environmental Noise Level Assessment of Quad Bike Rider Competency Assessment Circuit,
298 Tablelands Road, Cooran                                                                            Page 2 of 21



      2. Determine appropriate background noise level taking into account insect noise;


      3. Determine noise criteria using the DERM document Planning for Noise Control;


      4. Measure noise levels for quad bikes ridden by an in-experienced rider (maybe noisier than
           competent rider), and include in the report;

      5. Measure vehicle pass-by noise levels on Tablelands Road and volume of traffic, to allow
           comparison with future levels and volumes with quad bikes;

      6. Confirm tonality calculation of 2dBA;


      7. Provide 10 dBA vegetation attenuation, particularly given clearing of vegetation on Tablelands
           Road site since the older map used in the David Moore and Associates report;


      8. Confirm separation distances to the nearest residences using more recent aerial photography
           maps;


      9. Comment on the expected effect of noise travelling along the gully to residents and the
           "amphitheatre effect" with noise source relatively low and some houses at higher elevations.
           Additional noise measurements on site could be taken to clarify this effect.


      10. Re-assess noise impacts using a suitable noise model (eg. SoundPLAN)to take account of
           the effect of distance, terrain, air absorption, ground effect and meteorological conditions,
           and comment on the effect under adverse propagation conditions (i.e. temperature
           inversions, light downwind). The assessment noise sources should include: quad bike noise,
           voices of instructors/clients, staff and clients vehicles, maintenance of quad bikes and any
           other relevant sources (eg. Kawasaki Mule recovery vehicle noted in residents
           correspondence dated 6June 2012);

      11. The assessment should also include residences along Tablelands Road and near the
           entrance to the national park (i.e. residences on Lots 335,374,382, and 398);


      12. Comments on limiting hours of operation of tours to minimise the effect of noise annoyance
           on residents and temperature inversions       (eg. 9am   -

                                                                       4pm);

      13. Provide revised report including impact assessment of: quad bikes/ voices on circuit, quad
          bikes/ voices driving from circuit to Tablelands Road, and quad bikes/voices and client!staff
           vehicles on Tablelands Road.


This report details the results of a background noise assessment relative to the closest residences on
Tablelands Road, the results of a noise assessment of an experienced and an inexperienced quad
bike rider, the results of noise level measurements with and without a noise source at the quad bike
assessment circuit, at all of the closest residences to 298 Tablelands Road, including adjacent the
entrance to the National Park, noise limits and noise level impact from the quad bikes on the
test/training circuit. Tonality calculations are confirmed in this revised report, together with noise level
reduction from the quad bike competency assessment circuit to the closest residences for calm
atmospheric conditions.

People noise is included, but there is no client vehicles involved as they arrive and depart from the
quad bike competency assessment circuit by mini bus, so this does not require consideration.

Compliance with the noise limits based on this additional assessment voids the need for computer
noise modelling, consideration of traffic noise on Tablelands Road, determining precise separation
distances from the quad bike competency assessment circuit to the closest residences and
commenting on limiting hours of operation.
