Environmental Noise Level Impact Assessment for Proposed Addition of Second Floor to Block C and
Associated Increase to Bed Numbers for Flashpackers, 102 and 106 Pacific Avenue, Sunshine Beach Page 1 of 29
INTRODUCTION
David Moore & Associates Pty Ltd originally completed, in 2018, a noise impact assessment for the
existing backpacker accommodation (Visitor Accommodation Type 4 - Hostel) premises located at 102
Pacific Avenue, Sunshine Beach, to be expanded onto the adjoining residential property at 106 Pacific
Avenue, Sunshine Beach. Noosa Council subsequently approved this expansion of the backpacker
accommodation – Council Decision Notice reference 132007.2446.03. At this time Flashpackers had
69 approved beds across 102 and 106 Pacific Avenue, Sunshine Beach. Whilst this approval only
required a partial 1.8 metre high acoustic barrier on the north-western boundary, the as constructed
acoustic barrier extends all of the way to terminate adjacent to the western corner of Block C.
In 2020 David Moore & Associates Pty Ltd completed a further noise impact assessment report to
increase the number of beds within this backpacker accommodation by eleven (11), from 69 plus
manager to 80 plus manager, without making any changes to the overall size of the two buildings.
There were some internal room reconfiguration to achieve this increase in the number of guests, but
there were no changes to any part of the external shell of the buildings, windows, doors, etc. These
proposed changes never proceeded.
The existing Block A and Block B are two storey and Block C is single storey. It is now proposed to
add a second level to Block C, which will result in an additional maximum of 24 beds, but the existing
configuration of beds in dorms will be reduced, so that at any one time there will never be more than
80 beds. There will also be one additional carparking space. This current proposal was forwarded by
Noosa Council to their acoustic consultant, who provided the following preliminary comments:
• the location of any external air conditioning compressors;
• incidental noise generated by the proposed upper level;
• new carpark location and any impacts; and
• proximity of new stair/external access walkways etc to the new dorm area and neighbouring
properties would need to be understood and any potential impacts mitigated.
As a result of the above Council requested that an acoustic consultant review the proposal and
provide an assessment. In responding to the above comments, this report relies upon the previous
reports which we have prepared with respect to existing ambient noise levels, background sound
levels, noise limits, source noise levels, noise impact and noise control measures for the existing 69
bed backpacker accommodation, together with manufacturer noise data for the new air conditioning
units and the P J concepts and designs plans and elevations for the proposed amended layout for
Flashpackers.
All of the current noise control measures will remain in place, namely the 1.8m high acoustic barrier on
the rear (north-eastern) boundary of 106 Pacific Avenue and the 1.8 m high acoustic barrier on the
north-western boundary, from the northern corner to adjacent to the western corner of Block C.
This report has been prepared to assess any potential increase in noise impact to the adjoining
residential. The noise limit criteria has been based on the same criteria used for the 2018 report,
namely the noise limits contained in the Environmental Protection (Noise) Policy 2008 and the
adopted background sound levels based on the results of the 2009 ambient noise assessments,
together with a further 7-day ambient noise assessment in September 2018. The predominant noise
source in this area is traffic on Pacific Avenue, which is a direct link between the David Low Way and
Noosa Heads and carries a significant volume of traffic, together with the natural sounds of birds, wind
in the vegetation, domestic activities, etc. The September 2018 background sound levels were
specifically assessed adjacent to the closest adjoining residences, which are to the immediate north-
east of the subject site.

Associated Increase to Bed Numbers for Flashpackers, 102 and 106 Pacific Avenue, Sunshine Beach Page 2 of 29
With respect to the proposed second floor to Block C the potential noise impacts are:
• three additional air conditioning units, located at ground level on the north-western side of
Block C;
• addition of one extra carparking space (adjacent to Pacific Avenue and removing the small
external communal area adjacent to the bin storage area;
• guest noise from inside the new second floor dorms;
• guest noise from the access stairs and walkway to the new second floor of Block C.
In 2009 to assess the ambient noise levels relative to the closest boundary to Pacific Avenue, with the
ambient noise levels dominated by traffic, a 24-hour noise level study was conducted from Monitoring
Location A, on the front (Pacific Avenue) boundary of 102 Pacific Avenue with the microphone
elevated 2 metres.
To assess the general ambient noise levels for this residential area and establish appropriate noise
limits for noise from the subject site at the adjoining residential to the north-east a 24-hour ambient
noise assessment was conducted over a weekend from monitoring location B from adjacent the rear
boundary of 102 Pacific Avenue – boundary most distant from the influence of traffic noise from Pacific
Avenue, with the microphone also elevated 2 metres.
In September 2018 an extended 7-day ambient noise assessment was conducted from monitoring
location C, adjacent to the north-east boundary of the subject site and the closest adjoining residences
to the north-east, with the microphone elevated 1.8 metres.
This report details the results of these noise level studies, noise limits, and any noise level impact as a
result of the additional second floor to Block C, one additional carparking space and the additional 24
guests.

CRITERIA
Measurements and Calculations
All noise level measurements were conducted in accordance with the following:
• general requirements of the Queensland environmental protection legislation;
• Environmental Protection (Noise) Policy 2008;
• Noise Measurement Manual, Queensland Department of Environment and Heritage Protection,
Version 4 date 22 August 2013; and
• Australian Standard AS 1055.1-1997, Acoustics – Description and measurement of environmental
noise, Part 1 – General procedures.
Noise Limits
The Noosa Council Town Plan does not contain specific noise limits. However, in accordance with the
Environmental Protection (Noise) Policy 2008 the following should be noted:
1. Acoustic Quality Objectives. For the whole of Queensland the acoustic quality objectives are
target noise levels which should not be exceeded. These are, for residential:
• Outdoors, daytime and evening:
o 50 dB(A) LAeq,adj,1hr;
o 65 dB(A) LA1,adj,1hr; and
o 55 dB(A) LA10,adj,1hr;
• Indoors, daytime and evening:
o 35 dB(A) LAeq,adj,1hr;
o 45 dB(A) LA1,adj,1hr; and
o 40 dB(A) LA10,adj,1hr;
• Indoors, night-time:
o 30 dB(A) LAeq,adj,1hr;
o 40 dB(A) LA1,adj,1hr; and
o 35 dB(A) LA10,adj,1hr;
As it is not possible to assess inside the adjoining residential, the internal noise criteria needs to be
converted to the equivalent external criteria. To assist in converting the interior noise limits to
equivalent external noise limits, reference is made to the Department of Environment and Heritage
Protection Guideline, Noise Control, Planning for Noise Control, Version 1 dated 15 January 2016,
and in particular Table 7. Table 7 nominates different noise reduction levels for various states of
windows wide open, partially closed or completely closed, namely 5 dB(A), 10 dB(A) and 20 dB(A)
respectively. In addition, it should be noted that the ‘partially closed criteria’ protects at least 90
percent of the population from the adverse effects of transient noise, and for this reason a difference
of 10 dB(A) has been adopted to convert the interior noise criteria to the equivalent noise criteria
outside the residences.
Therefore, for the night-time period the equivalent external noise criteria would be:
• 30 + 10 = 40 dB(A) LAeq,adj,1hr;
• 40 + 10 = 50 dB(A) LA1,adj,1hr;
• 35 + 10 = 45 dB(A) LA10,adj,1hr;

2. Background Creep.
The ‘background creep’ noise limit criteria is specifically designed to adequately account from the
additive effect of a number of different noise sources, which can be generated by a number of
different premises. For the 2018 report the background creep criteria was adopted as the most
appropriate noise limit criteria. This is the criteria which has also been adopted in this report.
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
(b) for noise that varies over time measured by LAeq,adj,T – more than 5
dB(A) greater than the existing acoustic environment measured by
LA90,T.

From Table 1, the following average weekday and weekend background noise levels should be noted:
Weekday, Monitoring Location A
o daytime: 53 dB(A) LA90,T;
o evening: 46 dB(A) LA90,T;
o night: 39 dB(A) LA90,T;
Weekend, Monitoring Location B
o daytime: 47 dB(A) LA90,T;
o evening: 43 dB(A) LA90,T;
o night: 40 dB(A) LA90,T;
Based on the above 2009 background noise levels the background creep noise limits for the closest
adjoining residences to the north-east are:
• steady state noise: background + 0 dB(A): daytime = 47 dB(A) LA90,T;
evening = 43 dB(A) LA90,T;
night-time = 40 dB(A) LA90,T;
• time varying noise: background + 5 dB(A): daytime = 52 dB(A) LAeq,adj,T;
evening = 48 dB(A) LAeq,adj,T;
night-time = 45 dB(A) LAeq,adj,T.

From Table 2, the following average ambient noise levels should be noted:
o LAeq,T:
o daytime: 49.4, 48.9, 49.8, 49.2, 48.5, 48.1, 52.3 Average = 49.6 dB(A);
o evening: 44.8, 46.5, 44.3, 53.1, 44.4, 52.7, 45.9 Average = 47.4 dB(A);
o night-time: 42.0, 43.7, 41.4, 43.1, 43.2, 42.2, 43.6 Average = 42.7 dB(A);
o LA1,T:
o daytime: 58.4, 57.2, 58.6, 59.0, 57.7, 57.2, 63.1 Average = 58.7 dB(A);
o evening: 53.4, 55.9, 52.8, 57.7, 53.1, 57.7, 53.5 Average = 54.9 dB(A);
o night-time: 50.9, 51.4, 49.8, 52.4, 52.6, 52.5, 52.7 Average = 51.8 dB(A);
o LA10,T:
o daytime: 51.3, 51.1, 51.5, 51.9, 51.1, 50.7, 56.1 Average = 52.0 dB(A);
o evening: 47.4, 48.5, 46.9, 55.7, 46.8, 55.1, 48.3 Average = 49.8 dB(A);
o night-time: 44.3, 45.5, 44.1, 45.3, 45.4, 44.3, 45.8 Average = 45.0 dB(A);
o LA90,T:
o daytime: 42.1, 43.6, 43.9, 41.0, 41.8, 41.3, 43.2 Average = 42.4 dB(A);
o evening: 37.7, 40.6, 38.4, 47.5, 37.9, 46.9, 41.2 Average = 41.6 dB(A);
o night-time: 36.8, 38.3, 35.2, 37.0, 36.7, 35.6, 37.5 Average = 36.7 dB(A).
Based on the above 2018 background noise levels the background creep noise limits are:
Closest Residences to North-east
• steady state noise: background + 0 dB(A): daytime = 42 dB(A) LA90,T;
evening = 42 dB(A) LA90,T;
night-time = 37 dB(A) LA90,T;
• time varying noise: background + 5 dB(A): daytime = 47 dB(A) LAeq,adj,T;
evening = 47 dB(A) LAeq,adj,T;
night-time = 42 dB(A) LAeq,adj,T.
As the 2018 ambient noise assessment has resulted in lower noise limit criteria than the 2009

SOURCE NOISE LEVELS
On-Site Vehicle Noise
From previous noise level measurements conducted by the consultant, typical on-site vehicle noise
levels (time varying noise source) would be:
• car driving on driveway: 46 dB(A) LAeq,adj,T @ 8 m;
• car door closing: 48 dB(A) LAeq,adj,T @ 30 m;
• car engine starting: 48 dB(A) LAeq,adj,T @ 30 m.
People Laughing and Talking
In the 2018 report the following source noise level was used for people laughing and talking (69
guests):
• people laughing and talking: 54 dB(A) LAeq,adj,T @ 8 metres.
This is equivalent to a sound power level of 80 dB(A) LWAeq,adj,T.
The current proposal is for the total number of guests to not exceed 80. For the noise of people
laughing and talking the source noise levels can also be based on a paper presented at Acoustics
2011 by Hayne, M.J. titled ‘Prediction of Noise from Small to Medium Sized Crowds’ the applicable
formula for determining patron noise are:
• LWAeq = 15log10N + 64 dB(A);
• LWAmax = 11log10N + 81 dB(A).
where ‘N’ is the number of patrons.
As none of the external communal areas are changing in physical size so there would still be a similar
number of guests in all of these areas with the same source noise level as included in the 2020 report.
The only potential additional people noise impact with respect to the addition of a second floor to Block
C would be the guests inside these new dorms and guests accessing these dorms via the external
stair and walkway. There is accommodation for up to 24 guests inside the new second floor and there
could be up to an estimated 10 guests at any one time accessing these new dorms via the stairs and
walkway.
In accordance with the above formula the noise levels associated with the additional guests will be:
• 8 guests inside a dorm: 64 + 15 x log108 = 77.5 dB(A) LWAeq,adj,T. This is equivalent
to 51.5 dB(A) LAeq,adj,T @ 8m;
• 6 guests on stairs/walkway: 64 + 15 x log106 = 75.7 = 76 dB(A) LWAeq,adj,T. This is
equivalent to 49.7 = 50 dB(A) LAeq,adj,[email protected] primary areas where guests would be laughing and talking would be in the (covered) communal
area adjacent to Pacific Avenue, and the pool and deck adjacent to the pool.
The noise limits for the above noise source, at the adjoining residences to the north-east, are:
• daytime: 47 dB(A) LAeq,adj,T;
• evening: 47 dB(A) LAeq,adj,T;
• night-time: 42 dB(A) LAeq,adj,T.

NOISE LEVEL IMPACT
Vehicle Noise From Additional Carpark
From the source noise data used in the previous reports prepared for the subject site typical on-site
vehicle noise levels (time varying noise source) would be:
• car driving on driveway: 46 dB(A) LAeq,adj,T @ 8 m;
• car door closing: 48 dB(A) LAeq,adj,T @ 30 m;
• car engine starting: 48 dB(A) LAeq,adj,T @ 30 m.
For the proposed additional carpark on the south-western side of Block C the closest adjoining
residence is to the north-west, with the residence located towards the rear of the lot and the garages
at the Pacific Avenue end. At this residence, with an intervening boundary 1.2m high concrete block
wall, vehicle noise level impact at the closest habitable rooms would be:
• car driving on driveway: 46 dB(A) LAeq,adj,T @ 8 m – 8 (24m distance) – 8 (barrier effect of
intervening building) = 30 dB(A) LAeq,adj,T;
• car door closing: 48 dB(A) LAeq,adj,T @ 30 m + 2 (24m distance) – 8 (barrier effect of
intervening building) = 42 dB(A) LAeq,adj,T;
• car engine starting: 48 dB(A) LAeq,adj,T @ 30 m + 2 (24m distance) – 8 (barrier effect of
intervening building) = 42 dB(A) LAeq,adj,T;.
The noise limits for the above noise sources, at the adjoining residence to the north-west, are:
• daytime: 47 dB(A) LAeq,adj,T;
• evening: 47 dB(A) LAeq,adj,T;
• night-time: 42 dB(A) LAeq,adj,T.
The noise limits for the complete 24-hour period are complied with, and this compliance is achieved
with no additional noise control measures required.
People Noise
Block C Upper Floor
The applicable source noise levels are:
• 8 guests inside a dorm: 64 + 15 x log108 = 77.5 dB(A) LWAeq,adj,T. This is equivalent
to 51.5 dB(A) LAeq,adj,T @ 8m;
• 6 guests on stairs/walkway: 64 + 15 x log106 = 75.7 = 76 dB(A) LWAeq,adj,T. This is
equivalent to 49.7 = 50 dB(A) LAeq,adj,[email protected] closest residences which could be noise impacted by guests on the stairs leading up to the Block
C upper level dorms, and on the walkway, are those to the north-east. There is an existing 1.8 metre
high acoustic barrier on the north-eastern boundary of Flashpackers Noosa.
For guests inside a dorm on the upper level of Block C, all glazing will be fixed (un-openable) and the
minimum noise reduction achieved from inside to outside a dorm would be 20 dB(A).

Page 18
Flashpackers Noosa
Environmental Noise Level Impact Assessment for Proposed Addition of Second Floor to Block C and
Associated Increase to Bed Numbers for Flashpackers, 102 and 106 Pacific Avenue, Sunshine Beach Page 15 of 29
At the closest residential building to the north-east the noise level impact will be:
• 6 guests at base of stairs = 76.0 dB(A) LWAeq,adj,T – 33 (17m distance) – 8 (acoustic barrier) =
35 dB(A) LAeq,adj,T;
• 6 guests on walkway = 76.0 dB(A) LWAeq,adj,T – 35 (22m distance) = 41 dB(A) LAeq,adj,T;
• 8 guests inside dorm = 77.5 dB(A) LWAeq,adj,T – 20 (inside to outside dorm) – 27 (9m distance) =
30.5 = 31 dB(A) LAeq,adj,T.
The noise of 6 guests laughing and talking at either the base or the top of the stairs to the upper level
of Block C complies with the noise limits for the complete 24-hour day. This noise limit compliance is
achieved with no additional noise control measures in place. The noise of 8 guests laughing and
talking inside the closest dorm to the adjoining residence to the north-east the noise limits are also
complied with for the complete 24-hour day.
For the adjoining residence to the north-west there could be a maximum of 24 guests inside the three
new dorms on the upper level of Block C. With all windows fixed closed their noise level would be
reduced by at least 20 dB(A) from inside to outside the building and their noise level at the residence
to the north-west would be:
• (77.5 + 77.5 + 77.5 = 82.3) dB(A) LWAeq,adj,T – 20 (inside to outside building) – 24 (6m
separation distance) = 38.3 = 38 dB(A) LAeq,adj,T.
The noise of all of the 24 guests laughing and talking inside the upper level Block C dorms (with
windows closed) complies with the noise limits for the complete 24-hour day, with no additional noise
control measures required, at the adjoining residence to the north-west.
Swimming Pool Deck
If it is assumed that at any one time half of the total number of guests were on the pool deck and
surrounds, then their noise level would be:
• 64 + 15 x log1040 = 88.0 dB(A) LWAeq,adj,T
and their noise level impact at the closest residence to the north-east would be:
• 88.0 dB(A) LWAeq,adj,T – 35 (22m separation distance) – 8 (acoustic barrier) = 45 dB(A) LAeq,adj,T.
The noise limits for the above noise sources, at the adjoining residence to the north-east, are:
• daytime: 47 dB(A) LAeq,adj,T;
• evening: 47 dB(A) LAeq,adj,T;
• night-time: 42 dB(A) LAeq,adj,T.
For guests at the pool deck the noise limits for the daytime and evening (inclusive of the hours of
operation for the swimming pool and deck) are complied with, and this compliance is achieved with no
additional noise control measures required.

Roofed Communal Area
The roofed communal area is adjacent to Pacific Avenue and would have a capacity for up to
approximately 15 to 20 guests and has a perimeter acoustic barrier 1.8 metres high. At the closest
adjoining residence, which is to the north-west, the noise level of 20 guests laughing and talking (64 +
15 x log1020 = 83.5 = 84 dB(A) LWAeq,adj,T) would be:
• 84 dB(A) LWAeq,adj,T – 35 (22m distance) – 8 (acoustic barrier) = 41 dB(A) LAeq,adj,T.
For up to 20 guests in the roofed communal area adjacent to Pacific Avenue the 24-hour noise limits
are complied with, and this compliance is achieved with no additional noise control measures required.
Plant Noise
Three new air conditioning units are proposed for the new second floor of Block C – Daikin model
RXF35WVMA with a sound power level of 60 dB(A) for cooling and 61 dB(A) for heating, L WAeq,T.
These air conditioning units are to be located as per Figure 6. The top of these units is 550mm above
ground level.
The closest adjoining residence to these ground level air conditioning units is to the north-west, and at
this residence the noise of the three air conditioning units combined would be:
• 61 dB(A) + 4.8 (all three air conditioning units operating) – 22 (5m distance noise reduction) –
10 (intervening 1.8m high acoustic barrier) + 3 (reflected noise) = 36.8 = 37 dB(A) LAeq,adj,T.
The noise level of all three air conditioning units operating on the highest noise level (heating) at the
same time complies with the steady state noise limits at the closest residence to the north-west for the
complete 24-hour day, with no additional noise control measures required.
NOISE CONTROL
The noise level impact calculations detailed in this report assume that there are existing 1.8 metre
high acoustic barriers located as per Figure 2. If any of these acoustic barriers are in a poor state of
repair then to comply with the noise limits for the additional noise sources associated with the addition
of the upper floor for Block C they must be made good. In addition, the acoustic barrier on the north-
eastern boundary needs to be extended to the south-east to overlap with Block A by a minimum 2
metres. This small additional section of acoustic barrier must achieve compliance with the following:
• be a minimum 1.8 metres high relative to current ground levels;
• be located as per Figure 7;
• continuous and gap free;
• have a minimum surface area density of 10 kg/m2. Examples of suitable materials of
construction include, but are not limited to:
o reinforced concrete;
o concrete block;
o brick;
o hebel panel;
o sheet metal at least 2 mm thick;
o minimum 7.5 mm thick fibrous cement sheet;
o earth mound;
o lapped timber palings, for example, kiln dried softwood palings at least 19 mm thick
and overlapped a minimum 20 mm;
o any combination of the above.
With the 1.8 metre high acoustic barriers located as per Figure 7 in place, in conjunction with
separation distance and intervening building/s acting as acoustic barriers, all potential noise sources
associated with the proposed addition of a second floor to Block C, three air conditioning units (to

CONCLUSIONS
David Moore & Associates Pty Ltd has conducted previous noise impact assessments for the subject
site, with the original report in 2018 for the site now inclusive of 102 and 106 Sunshine Avenue and
three dorm blocks – Blocks A and B being two storey and Block C single storey, for a total of 69
guests.
It is now proposed to add the following:
• second storey to Block C, which will include three dorms, each to accommodate up to a
maximum of 8 guests (total maximum additional number of guests = 24). The total number of
guests on site will not exceed 80.
• additional carparking space in the current external communal area adjacent to Pacific Avenue.
• three additional air conditioning units to service the upper floor of Block C, noting that all dorm
windows will be fixed closed (un-openable).
Noise sources associated with the addition of an upper floor level to Block C include and an increase
in the maximum number of guests from 69 to 80:
• guest noise accessing the upper level of Block C – stairway and walkway;
• higher number of guests in the pool and deck area;
• up to 20 guests in the roofed communal area;
• guest noise from inside the new dorms for the upper level of Block C;
• vehicle noise associated with the additional carparking space;
• noise from the three new air conditioning units.
All of the above potential noise sources were calculated to the closest adjoining residences and
compared to the noise limits for the daytime, evening and night-time periods. These noise limits were
found to be complied with provided that the acoustic barriers detailed in Figure 7 of this report are in
place and that the pool and associated deck are only available for use from 0700 to 2200 hours daily.
RECOMMENDATION
It is recommended that, from an environmental noise perspective, the proposed addition of a second
level to Block C, a maximum number of 80 guests, three additional air conditioning units and one
additional carparking space be approved, provided that the noise control measures detailed in this
report are incorporated into this development.
