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 13 of 21




     6. Confirm tonality calculation of 2dBA;


         Calculated tonal adjustment of 0 dB{A)for experienced rider and 1.1 dB{A) for inexperienced
         rider. Tonal calculation for inexperienced rider detailed in this report.


     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;


         On-site noise level measurements were used to determine attenuation due to distance,
         vegetation and topography from the competency assessment circuit to the closest adjoining
         residences (268,295 and 374 Tablelands Road). These measurements were conducted with
         and without a noise source located at the competency assessment circuit.


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


         Not required as noise level reduction to the closest adjoining residences to the competency
         assessment circuit determined by on-site noise level measurements.


      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.


         On-site noise level measurements used to determine the effect of noise travelling along the
         gully to residents.

      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);

          Noise modelling not required as on-site noise assessments conducted from competency
                                                                                    included in this
         assessment circuit to closest residences. Recovery vehicle and voice noises
         assessment.


      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);


          Assessment included consideration of noise impact at residence at 374
                                                                                  Tablelands Road.
                                                            and the other residences considered, would
          Compliance with noise criteria at this residence,
                                       the residences at 335,382  and  398 Tablelands  Road.
          also result in compliance at


       12. Comments on limiting hours of operation of tours to minimise the
                                                                                         effect of noise annoyance

           on residents and temperature inversions (eg.
                                                        9am 4pm);    -




          Not required as daytime noise criteria complied with.


       13. Provide revised report including impact assessment of: quad                          quad
                                                                                 bikes/ voices on circuit,

            vehicles on Tablelands Road.


          Revised report provided.
