Mark Bain Constructions Pty Ltd Environmental Noise Level Impact Assessment for Proposed Wave Lagoon, 500/90 Beach Road, Noosa North Shore Page 1 of 16 INTRODUCTION It is proposed to establish a private wave lagoon at 500/90 Beach Road, Noosa North Shore (Lot 500 on SP 215779), in the south-east corner of this property. Potential noise sources associates with this wave lagoon, which will be approximately 0.4 Ha in area, are the blowers used to generate the waves and people noise. There will also be pumps used in association with the wave lagoon, for the purpose of water transfer and water filtration/treatment. The noise of the blowers and pumps is steady state whilst the noise of people is time varying. To determine the existing acoustic environment a 7-day ambient noise assessment was conducted from the subject site, from adjacent to one of the closest adjoining residences. Typical source noise data for the pumps and people is already held by the consultant, whilst wave lagoon blower noise was obtained from an acoustic report prepared for a similar scale wave lagoon at Palm Springs, California. With respect to noise limits the now superseded version of the Environmental Protection (Noise) Policy 2008 contained details of ‘background creep’ and allocated actual noise limits for both steady state and time varying noise sources. From previous work conducted by the consultant in the Noosa Council area this is the noise limit criteria which was applied. However, whilst background creep is still detailed in the current Environmental Protection (Noise) Policy 2019, no actual noise limits are defined. Currently the only noise criteria defined by the environmental protection legislation are the default noise standards of the Environmental Protection Act 1994 and the Acoustic Quality Objectives of the Environmental Protection (Noise) Policy 2019. In preparing this report the site plan prepared by Tim Ditchfield Architects, project 1732, drawing CD 1.01 dated June 2019 was referenced. Refer Figure 1 for locality plan and noise monitoring location and Figure 2 for proposed site plan. David Moore & Associates Pty Ltd Our reference: R19099/D3453/Rev.0/21.01.2020

CRITERIA
All noise level measurements were conducted in accordance with the following:
general requirements of the Queensland environmental protection legislation;
Environmental Protection (Noise) Policy 2019;
Noise Measurement Manual, Queensland Government, Department of Environment and Heritage
Protection, Version 4, August 2013;
Australian Standard AS 1055-2018, Acoustics – Description and Measurement of Environmental
Noise.
NOISE LIMITS
For all of the steady state and time varying noise sources the noise limits have been defined in
accordance with the Acoustic Quality Objectives and the default noise standards of the Queensland
environmental protection legislation.
In accordance with the default noise standards there are no noise limits for blowers, but the noise
limits for pumps (which, by definition includes spa blowers) are:
daytime (0700 to 1900 hours): background + 5 dB(A);
evening (1900 to 2200 hours): background + 3 dB(A);
night-time (2200 to 0700 hours): inaudible.
It has been assumed that the above noise limit criteria would be equally applicable to blowers as well
as pumps.
The acoustic quality objectives are:
Acoustic quality objectives, daytime and evening, external to dwelling:
o 50 dB(A) LAeq,adj,1H;
o 55 dB(A) LA10,adj,1H; and
o 65 dB(A) LA1,adj,1H;
Acoustic quality objectives, daytime and evening, inside dwelling:
o 35 dB(A) LAeq,adj,1H;
o 40 dB(A) LA10,adj,1H; and
o 45 dB(A) LA1,adj,1H;
Acoustic quality objectives, night-time, inside dwelling:
o 30 dB(A) LAeq,adj,1H;
o 35 dB(A) LA10,adj,1H; and
o 40 dB(A) LA1,adj,1H;
For the night-time period the internal noise criteria needs to be converted to be equivalent to outside
the closest residences. Allowing a 5 dB(A) noise level reduction from outside to inside (based on all of
the windows fully open and in accordance with the Queensland Environmental Protection Agency
Ecoaccess Guideline Planning for Noise Control) the internal criteria would be equivalent to the
following levels external to the dwelling:

Night-time
o 35 dB(A) LAeq,adj,1H;
o 40 dB(A) LA10,adj,1H; and
o 45 dB(A) LA1,adj,1H.
AMBIENT NOISE LEVEL MEASUREMENTS
Table 1 details the results of the ambient noise assessment conducted from the monitoring location on
the subject site for the daytime, evening and night-time periods – refer Figure 1 for further detail,
Appendix A for details of measurement equipment, equipment settings, calibration, etc., Appendix B
for graphical presentation of key parameters and Appendix C for atmospheric conditions.
With respect to noise the following should be noted:
daytime: 0700 to 1800 hours;
evening: 1800 to 2200 hours;
night-time: 2200 to 0700 hours;
‘A’ weighted: adjustment made by the sound level meter to the measured noise to
correspond to the response of the human ear. This adjustment is
standardised by international noise standards;
LAeq,T: the equivalent continuous (or approximately the ‘average’) ‘A’ weighted sound
pressure level for the measurement period ‘T’;
LA1,T: the ‘A’ weighted sound pressure level exceeded for 1% of the measurement
period ‘T’;
LA10,T: the ‘A’ weighted sound pressure level exceeded for 10% of the measurement
period ‘T’, which is an approximation of the ‘average of the maximum noise
levels’;
LA90,T: the ‘A’ weighted sound pressure level exceeded for 90% of the measurement
period ‘T’, which is an approximation of the ‘average of the minimum noise
levels’, which is also known as the ‘background’ noise level.

With respect to the above night-time ambient noise levels, the Acoustic Quality Objectives for the
night-time are:
o 35 dB(A) LAeq,adj,1H;
o 40 dB(A) LA10,adj,1H; and
o 45 dB(A) LA1,adj,1H.
The current average night-time ambient noise levels exceed this noise limit criteria by 6.5 dB(A)
LAeq,1H, 6.6 dB(A) LA1,1H and 1.8 dB(A) LA10,1H. This difference between the current average night-time
ambient noise levels and the noise limits should ensure that any noise from the proposed wave lagoon
will be either inaudible or only just barely audible at the closest residential.
Based on the above the noise limits are:
pumps and blowers:
o daytime (0700 to 1900 hours): 41 + 5 = 46 dB(A) LAeq,adj,T;
o evening (1900 to 2200 hours): 39 + 3 = 42 dB(A) LAeq,adj,T;
o night-time (2200 to 0700 hours): inaudible = ≤ 30 dB(A) LAeq,adj,T;
people noise:
o daytime and evening:
50 dB(A) LAeq,adj,1H;
55 dB(A) LA10,adj,1H; and
65 dB(A) LA1,adj,1H;
o night-time:
35 dB(A) LAeq,adj,1H;
40 dB(A) LA10,adj,1H; and
45 dB(A) LA1,adj,1H;
SOURCE NOISE LEVELS
Typical source noise levels are:
Steady state sources:
blower (total of 8):
o discharge air: 119 dB(A) LWA each;
o casing radiated: 88 dB(A) LWA;
pump (assumed 2 of): 90 dB(A) LWA;
Time varying noise source:
people: 62 dB(A) LAeq,adj,T, 70 dB(A) LA1,adj,T and 65 dB(A) LA10,adj,T @
10 m.
The blower source noise data was extracted from a report prepared for a wave lagon (believed to be
of similar size) at Palm Springs, California. The quoted blower is manufactured by Chicago Blower
Corporation, model 6105SW.
It is believed that the blowers and pumps will be located under-ground/built into an embankment and
contained within a concrete structure (or equivalent) – concrete floor, walls and roof. It has been
further assumed that the concrete structure will have a minimum Rw 50 (noise reduction of 45 dB(A)).

NOISE LEVEL IMPACT
The concrete structure containing the blowers and pumps is proposed to be located adjacent to the
western corner of the wave lagoon, which has a separation distance of approximately:
160 metres to the closest residence to the west:
700 metres from the closest residence to the south.
Compliance with the noise limits at the closest residence to the west will also result in noise limit
compliance at all other nearby residences.
Whilst it is most likely that the wave lagoon will only be used during daylight hours, this could be as
early as 0500 hours in the summer. There is also a small likelihood that the wave lagoon could be
used during the evening, up to 2200 hours. It has been assumed that the generation of waves could
occur at any time from 0500 hours to 2200 hours.
Steady State Noise Sources
At the closest residence to the west the noise of the plant and equipment, which will all be located
inside a concrete structure (or equivalent) the noise level impact would be:
blower discharge: 119 LWA + 9 (total of eight blowers) – 52 (distance of 160m) – 45
(concrete structure) – 7 (ground) = 24 dB(A) LAeq,adj,T;
122 LWA + 9 – 52 – 45 – 7 = 27 dB(A) LA1,adj,T;
120 LWA + 9 – 52 – 45 – 7 = 25 dB(A) LA10,adj,T;
blower radiated: 88 LWA + 9 (total of eight blowers) – 52 (distance of 160m) – 45
(concrete structure) – 7 (ground) = -7 dB(A) LAeq,adj,T;
91 LWA + 9 – 52 – 45 – 7 = -4 dB(A) LA1,adj,T;
89 LWA + 9 – 52 – 45 – 7 = -6 dB(A) LA10,adj,T;
pumps: 90 dB(A) LWA + 3 (two pumps) – 52 (distance of 160m) – 45
(concrete structure) – 7 (ground) = -11 dB(A) LAeq,adj,T;
93 dB(A) LWA + 3 – 52 – 45 – 7 = -8 dB(A) LA1,adj,T;
91 dB(A) LWA + 3 – 52 – 45 – 7 = -10 dB(A) LA10,adj,T;
combined: 24 dB(A) LAeq,adj,T, 27 dB(A) LA1,adj,T and 25 dB(A) LA10,adj,T.
The combined noise level of all of the eight blowers and two pumps comply with both the default noise
standard for pumps, as well as the acoustic quality objectives.
Time Varying Noise Source
The most likely time varying noise source is people noise from the wave lagoon, with a separation
distance of approximately 180 metres to the closest residence to the west.
At this closest residence to the west the noise level impact of the time varying noise source will be:
people: 62 dB(A) LAeq,adj,1H @ 10m – 25 (distance of 55m) – 7 (ground) = 30 dB(A)
LAeq,adj,1H;
70 dB(A) LA1,adj,1H @ 10m – 25 – 7 = 38 dB(A) LA1,adj,1H;
65 dB(A) LA10,adj,1H @ 10m – 25 – 7 = 33 dB(A) LA10,adj,1H;
The above people noise complies with the acoustic quality objective criteria for the daytime, evening
and night-time, with no additional noise control measures required.

Mark Bain Constructions Pty Ltd Environmental Noise Level Impact Assessment for Proposed Wave Lagoon, 500/90 Beach Road, Noosa North Shore Page 9 of 16 NOISE CONTROL To be able to operate the wave lagoon from 0500 to 2200 hours daily, based on the source noise data available to the consultant at the time of preparing this report, all plant and equipment must be located inside a concrete structure (or equivalent) with a minimum Rw 50. Once all of the plant and equipment has been selected, the actual building location, design and materials of construction defined, together with manufacturers’ source noise data for the actual equipment to be installed, an acoustic consultant must be appointed to re-calculate noise level impact. If any of the noise limits are exceeded, appropriate noise control measures must be defined. CONCLUSIONS It is proposed to establish a private wave lagoon at 500/90 Beach Road, Noosa North Shore (Lot 500 on SP 215779), in the south-east corner of this property. Potential noise sources associates with this wave lagoon, which will be approximately 0.4 Ha in area, are the blowers used to generate the waves and people noise. There will also be pumps used in association with the wave lagoon, for the purpose of water transfer and water filtration/treatment. The noise of the blowers and pumps is steady state whilst the noise of people is time varying. To determine the existing acoustic environment a 7-day ambient noise assessment was conducted from the subject site, from adjacent to one of the closest adjoining residences. Typical source noise data for the pumps and people is already held by the consultant, whilst wave lagoon blower noise was obtained from an acoustic report prepared for a similar scale wave lagoon at Palm Springs, California. Whilst it is most likely that the wave lagoon will only be used during daylight hours, this could be as early as 0500 hours in the summer. There is also a small likelihood that the wave lagoon could be used during the evening, up to 2200 hours. It has been assumed that the generation of waves could occur at any time from 0500 hours to 2200 hours. For the steady state noise sources these all comply (individually and combined) with the default noise standards and the acoustic quality objectives. This is for the noise sources applied in this report and assuming that these steady state noise sources are located within a concrete structure with a minimum Rw 50. Once the actual noise sources are determined, and their associated noise levels available, an acoustic consultant must re-calculate noise impact. If any of the noise limits are still exceeded then noise control measures must be defined. For the time varying noise source – people – this complies with the acoustic quality objectives for the proposed hours of operation (0500 to 2200 hours daily), with no additional noise control measures required. RECOMMENDATION It is recommended that, from an environmental noise perspective, the proposed wave lagoon be approved, with no additional noise control measures required.
