Environmental Noise Level Assessment of Quad Bike Rider Competency Assessment Circuit,
298 Tablelands Road, Cooran Page 1 of 21
INTRODUCTION
Based on advice from Charles Marais Noosa Quad Bike Tours have all of the necessary approvals to
conduct quad bike tours on public roads and within the nearby National Park, in the Sunshine Coast
hinterland. These tours will be conducted with up to 12 quad bike riders, and all of the quad bikes will
be supplied by Noosa Quad Bike Tours.
Whilst some of the participants may have previous experience with riding a quad bike, others will not
and, therefore, the competency of the participants needs to be assessed prior to riding on public
roads. It is intended that this competency testing would be conducted on land owned by Charles
Marais and located at 298 Tablelands Road, Cooran. The small test/training ’circuit’ is located down a
steep decline from Tablelands Road in a gully, on the eastern side of Tablelands Road (with this road
generally running along a ridge in this area) with the closest residential being approximately:
. 420 m to the north, 374 Tablelands Road;
. 310m to the north-west, 335 Tablelands Road;
. 350 m to the west, 301 Tablelands Road;
. 200 m to the south, 268 Tablelands Road; and
. 380 m to the south-east, 295 Tablelands Road.
The area between the proposed quad bike test/training circuit and these nearby residences is
predominantly densely vegetated. Refer to Figure 1 for more detail, including the approximate
location of the test/training circuit and these closest residences.
In accordance with an email from Rhian Davies, Environment Officer, Sunshine Coast Regional
Council, in early April 2012, Noosa Quad Bike Tours were required to conduct a noise assessment of
the quad bikes using the test/training circuit at 298 Tablelands Road, C oran, for up to 12 quad bikes,
to determine noise impact at all of the nearby residences (located as detailed above).
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 brief background noise assessment.
Quad bike noise levels were then calculated to all of the closest residences, with due consideration of
separation distance, intervening vegetation and topography, and up to 12 quad bikes using the
test/training circuit simultaneously. These calculations predicted the following quad bike noise levels
(for 12 quad bikes on the competency assessment Circuit) at the closest residential:
. 335 Tablelands Road: 33.2 dB(A) LA1O,adj,T;
. 301 Tablelands Road: 28.2 dB(A) LA1O,adj,T;
. 268 Tablelands Road: 36.2 dB(A) LA10,adj,T; and
. 295 Tablelands Road: 32.2 dB(A) LA10,adj,T.
This report suggested a noise limit of 38 dB(A) LA1O,adj,T, which all of the above predicted noise levels
comply with.
conducted
Subsequent to this report being presented to Council, a third party review of my report was
& Associates
by Savery and Associates. A copy of this review has not been provided to David Moore
from Sunshine Coast Regional Council to Charles Marais dated 18 June 2012,
Pty Ltd, but in a letter
Council stated:
’. the council’s acoustic consultant has recommended that additional monitoring and assessment is
..
required to a,dequately address potential noise issues associated with operation of the quad bike
tours, including:-
1. Undertake noise logging for at least 7days, at a suitable location representative of the
surrounding houses;

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.

Noise Limits
At a separation distance of greater than 50 to 100 metres the noise from the quad bikes using the
test/training circuit would be relatively constant and best described as ’steady state’ noise. For steady
state or constant noise the most appropriate noise limit is the ’background plus allowance’ criteria,
which is background plus 5 dB(A) for the daytime, from 0700 to 1800 hours. This noise limit is
expressed as the average of the maximum source noise levels, adjusted for any tonal and/or
impulsive components, which is equivalent to the noise level exceeded 10% of the sample duration,
denoted LA10,T.
This is the noise limit that was applied in the initial version of this report, and is still considered
appropriate.
In addition to the above the Environmental Protection (Noise)Policy 2008 has the following
requirement with respect to background creep for steady state noise (which is the noise of the
airconditioning plant):
"10 Controlling Background Creep
(1) This section states the management intent for an activity involving noise.
(2) To the extent that it is reasonable to do so, noise from an activity must not be-
a) For noise that is continuous noise measured by LA90,T more than nil dB(A)
-
"
greater than the existing acoustic environment measured by LA90,T; or ...

SOURCE NOISE lEVEL
April 2012
With one quad bike using the competency assessment circuit at a speed representative of a person
who has previously ridden a quad bike (experienced rider), a noise assessment was conducted at 10
metres from the closest part of the circuit in April 2012. Sound level meter sampling rate was set to 2
second intervals, to ensure that all events were measured. Refer Appendix A details the
measurement equipment, equipment settings, calibration, monitoring location and atmospheric
conditions and Appendix B for a complete set of results.
Whilst the quad bikes will all be governed (controlled to a maximum number of revs), a noise
assessment was also conducted with the quad bike ungoverned to determine any difference in the
noise level.
From Appendix B the following noise levels should be noted:
.
quad bike governed, first set of circuits: 63.1 dB(A) LA1O,T average;
.
quad bike governed, second set of circuits: 64.1 dB(A) LA1O,T average;
.
quad bike ungoverned, doing circuits: 62.9 dB(A) LA1O,T average.
As the quad bike will be governed for all Noosa Quad Bike Tour riders, the adopted source noise level
for one quad bike is the average of the governed results, namely 63.6 dB(A) LA1O,T.
July 2012
In July 2012 a further noise assessment was conducted of one quad bike being ridden on the
competency assessment circuit, firstly by an experienced rider, then an inexperienced rider. The
results of these noise assessments were:
.
experienced rider: 62.4 dB(A) LAeq,T, 66.2 dB(A) LA1O,T and 56.6 dB(A) LA90,T;
.
inexperienced rider: 59.3 dB(A) LAeq,T, 62.8 dB(A) LA1O,T and 49.2 dB(A) LA90,T.
For these two assessments tonality was calculated from the 1/3rd octave frequency spectrum data in
accordance with the Ecoaccess Guideline Planning for Noise Control, Appendix A: Determination of
Tonal Adjustment (KI). Calculation resulted in tonal adjustments of 0dB(A)for the experienced rider
and 1.1 dB(A) for the inexperienced rider, as per Table 3.

Table 3
Calculation of Tonality for Experienced Quad Bike Rider
From the 1/3rd octave frequency spectrum of the quad bike a tonal adjustment of +1.1 dB(A) was
calculated as per Table 3, for an inexperienced rider. There is no impulsive noise associated with the
use of the quad bike.
In July 2012 (Tuesday 9 July) a noise assessment was conducted with a noise source located at the
closest
competency assessment circuit to simulate twelve quad bike riders on the circuit, and at the
residences. The results of the noise these measurements are detailed in Table 4.

Table 3
Calculation of Tonality for Experienced Quad Bike Rider
From the 1/3” octave frequency spectrum of the quad bike a tonal adjustment of +1.1 dB(A) was
calculated as per Table 3, for an inexperienced rider. There is no impulsive noise associated with the
use of the quad bike.
In July 2012 (Tuesday 9 July) a noise assessment was conducted with a noise source located at the
competency assessment circuit to simulate twelve quad bike riders on the circuit, and at the closest
residences. The results of the noise these measurements are detailed in Table 4.

NOISE LEVEL IMPACT
April 2012 -
Competency Assessment Circuit
From the results of the April 2012 noise level measurements, quad bike noise levels were calculated
to closest residences, with due consideration of separation distance, intervening vegetation and
topography, and 12 quad bikes using the competency assessment circuit simultaneously. These
calculations predicted the following quad bike noise levels (for 12 quad bikes on the competency
assessment circuit) at the closest residential:
335 Tablelands Road: 33.2 dB(A) LA1o,adj,T;
301 Tablelands Road: 28.2 dB(A) LA1o,adi,T;
268 Tablelands Road: 36.2 dB(A) LA1O,adi,T; and
295 Tablelands Road: 32.2 dB(A) LA1o,adi,T.
and for four quad bikes on the competency assessment circuit their noise level at the closest
residential would be 4.2 dB(A) less (as per my letter G120921D2670/DJM dated 1 July 2012):
. 335 Tablelands Road: 29.0 dB(A) LA1o,adi,T;

Recovery Vehicle and Voices
Recovery Vehicle
In accordance with the results of the source noise level measurements detailed in Table 4 the
recovery vehicle (Kawasaki Mule) at normal operating revs is 1.3 dB(A) LA1O.T greater than the
~oise
of one quad bike ridden by an experienced rider. Based on the noise levels calculated in Table 5 the
noise level of this recovery vehicle, from the competency assessment circuit at the closest adjoining
residences, would be:
268 Tablelands Road: 30.5 + 1.3 = 31.8 dB(A) LA10,T;
. 295 Tablelands Road: 27.1 + 1.3 = 28.4 dB(A) LA10,T;
. 374 Tablelands Road: -22.2 + 1.3 = -23.5 dB(A) LA10,T.
This recovery vehicle is road registered and is currently ridden by the owner up and down Tablelands
Road to visit his neighbours. Therefore it is a noise source which is already present in the area and
should not require any noise consideration with respect to the quad bike tours, as it is not introducing
a new noise source.
Voices
The noise of peoples voices talking and laughing has been previously assessment by the consultant
at a number of different venues, with a source noise level of approximately 60 dB(A) LA10,adj,[email protected] is the source noise for a group of at least 15 to 20 people talking and laughing, which is more
than would be present at the competency assessment circuit at anyone time.
This source noise is 6 dB(A) and 4 dB(A) LA10,adj,T less than the noise of one quad bike with an
experienced and inexperienced rider respectively on the competency assessment circuit. The
additive effect of the noise of people laughing and talking (to quad bike/s on the competency
ass_essment circuit) would be s; 1 dB(A), with + 1 dB(A) at the closest residential being the worst case
scenario.
State of Compliance
For the daytime period the average background noise level was 37.6 dB(A) LA90,T. For steady state
limit of
noise a commonly applied daytime noise limit criteria is ’background + 5 dB(A)’, giving a noise

Even if the absolute minimum daytime background noise level of 28.7 dB(A) LA9o.15min is adopted, this
background noise level is not exceeded by the noise of up to four quad bikes on the competency
assessment circuit at any of the closest residences (noise levels at residences in Table 5 reduced by
9.6 dB(A) for an experienced rider and reduced by 13.3 dB(A) for an inexperienced rider).
CONCLUSIONS
Prior to allowing participants out on public roads, Noosa Quad Bike Tours intend to conduct a
competency assessment of riders on a circuit at their property at 298 Tablelands Road, Cooran. Up to
12 quad bikes will be involved in each tour and there could be up to 4 quad bikes on the competency
assessment circuit at anyone time. This test/training ’circuit’ is loc ted approximately 70 metres down
a steep decline from Tablelands Road in a gully, on the eastern side of Tablelands Road.
Sunshine Coast Regional Council have requested Noosa Quad Bike Tours to provide additional
information on a number of occasions, the most recent in a letter dated 18 June 2012. This revised
report details the response to this request for additional information, as follows:
1. Undertake noise logging for at least 7days, at a suitable location representative of the
surrounding houses;
Noise logging was undertaken for a four day period, including weekdays and weekend, from
301 Tablelands Road, Cooran, at a time when there was no influence from insects and at a
location relative to the closest adjoining residences to the competency assessment circuit at
298 Tablelands Road.
2. Determine appropriate background noise level taking into account insect noise;
As per 1. above the background noise assessment was not influenced by insect noise.
3. Determine noise criteria using the DERM document Planning for Noise Control;
The above DERM document details criteria for allowing for ’background creep’. This
Guideline is not legislation and is dated 2004. The Environmental Protection (Noise)Policy
2008 is legislation and more recent document, so the requirements for ’background creep’

During the noise assessments at the three closest adjoining residential properties which were
accessed by the consultant, a source noise level of 76 dB(A) LA90,T and 78 dB(A) LA10,T was audible at
the closest side of the residences at 268 and 295 Tablelands Road, and only just barely audible on the
side of the deck closest to this noise source at 374 Tablelands Road.
Without the noise source present the background noise levels at these residences, at the time of this
assessment, were 35 to 37 dB(A) LA90,T with no insect noise present.
The atmospheric conditions, at the time of this assessment, were representative of worst case
scenario for the residences to the north, near the entrance to the National Park.
RECOMMENDATION
It is recommended that the quad bike competency assessment circuit at 298 Tablelands Road,
Cooran be approved, with no noise control measures required, for daytime use.
