INTRODUCTION
The Parkridge development includes a Facilities Building at 75 Resort Drive, Noosa Heads. This
Facilities Building comprises:
reception;
café;
outdoor dining;
shared multipurpose room;
gymnasium;
convenience store;
kitchen;
office;
amenities.
The proposed hours of operation of the café and outdoor dining areas of the Facilities Building are 0600
hours to midnight, daily. All of the plant and equipment for this Facilities Building are located within a
dedicated rooftop plant deck.
With respect to the Facilities Building, potential noise sources include:
1. plant and equipment;
2. gymnasium equipment;
3. patron noise;
4. amplified music;
5. delivery vehicles;
6. waste collection.
Each of these potential noise sources has been calculated to the closest residential and compared to
the noise limits. In those instances where the noise limits are not complied with suitable noise control
measures have been nominated.
Refer Figure 1 for the location of the Facilities Building relative to all on-site residential for Parkridge.
Compliance with the noise limits at the on-site Parkridge residential would also result in noise limit
compliance at all other nearby residential. Figure 2 is a floor plan for the Facilities Building.
In preparing this report the architectural drawings prepared by Blackburne Jackson Design, project
number 7038, were referenced, together with the mechanical drawings prepared by Ashburner Francis.

CRITERIA
Noise Criteria
For the Parkridge development potential noise impact is with respect to the surrounding residential
units, both with respect to balconies and internal habitable rooms.
Environmental Protection (Noise) Policy 2008
In accordance with the Environmental Protection (Noise) Policy 2008, Schedule 1 describes the
following Acoustic Quality Objectives for dwellings:
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, night-time:
o 30 dB(A) LAeq,adj,1hr;
o 40 dB(A) LA1,adj,1hr; and
o 35 dB(A) LA10,adj,1hr;
To enable assessment against the above criteria the indoor criteria requires adjustment to be equivalent
to outside the residential units. For a fully open window the noise level reduction from outside to inside
is 5 dB(A) (Eccoaccess ‘Planning for Noise Control’, Department of Environment and Heritage
Protection, 15 January 2016 refers).
Therefore, the equivalent external noise levels for the night-time period are:
o 30 + 5 = 35 dB(A) LAeq,adj,1hr;
o 40 + 5 = 45 dB(A) LA1,adj,1hr; and
o 35 + 5 = 40 dB(A) LA10,adj,1hr;
In addition to the above the Environmental Protection (Noise) Policy 2008 also describes noise limits to
accommodate ‘background creep’. These noise limits, for time varying noise sources, are ‘background
+ 5 dB(A)’, with the noise limit expressed as the LAeq,adj,T, and ‘T’ has been assumed to be 15 minutes.
Noosa Council Parkridge Approval
In accordance with the Noosa Council Change to an Existing Approval document dated 18 October
2019 (Council reference 132005.1133.10) the following should be noted with respect to noise and the
Facilities Building:
81. Noise emission from mechanical plant and equipment (air conditioners, refrigeration
equipment or pool pumps, etc) shall comply with the following requirements:
a. A person must not use equipment on any day if it makes or causes noise to be made:

i. From 10pm to 7am, not more than the higher of either:
a) 40 dB(A);
b) 3 dB(A) above the background noise level;
No audible noise for pool pumps apply during these hours.
ii. From 7am to 7pm, not more than the lower of either:
a) 50 dB(A);
b) 3 dB(A) above the background noise level;
iii. From 7pm to 10pm:
a) Not more than 3 dB(A) above the background noise level
With respect to the above extract it should be noted that this is not a direct transcript, as some of the
detail was not included in the Noosa Council Change to an Existing Approval document dated 18
October 2019 (Council reference 132005.1133.10).
Australian Standard 2107:2000
In accordance with Australian Standard 2107:2000 Acoustics – Recommended design sound levels and
reverberation times for building interiors the recommended design sound levels for building interiors,
namely houses and apartments near minor roads, are:
Recommended Level, LAeq,
Type of Occupancy dB(A)
Satisfactory Maximum
Living area 30 40
Sleeping area 30 35
Work areas 35 40
For the night-time period for sleeping areas the above 30 dB(A) L Aeq,T is the same as the acoustic
quality objective for the same time period, for inside.
Measured Evening Background Noise Level
On Monday 2 December and Wednesday 18 December 2019 noise assessments were conducted
adjacent to the rear (eastern) boundary of Block 3, with the kitchen exhaust fan of the Facilities Building
turned off and any other plant and equipment associated with the Facilities Building inaudible.
For Monday 2 December the early evening background sound level was an average of 40 dB(A) LA90,T.
For Wednesday 18 December the late evening background sound level was 38 dB(A) LA90,T.
The adopted evening (1800 to 2200 hours) background sound level is 40 dB(A) LA90,T and the adopted
early night-time (2200 hours to midnight) background sound level is a conservative 35 dB(A) LA90,T.

Noise Limits
Based on the above and the fact that all of the closest residential are apartment buildings, the noise
limits which have been adopted in this report, for immediately outside a residential apartment, are as
described by Condition 81 of the Noosa Council approval for steady state noise and, for time varying
noise sources, as follows:
Steady State Noise Source
daytime (0700 to 1900 hours): 50 dB(A) LAeq,adj,T;
evening (1900 to 2200 hours): 43 dB(A) LAe,adj,T;
night-time (2200 hours to midnight): 38 dB(A) LAeq,adj,T.
Time Varying Noise Source
daytime (0700 to 1800 hours): 50 dB(A) LAeq,adj,T;
evening (1800m to 2200 hours): 45 dB(A) LAe,adj,T;
night-time (2200 hours to midnight): 40 dB(A) LAeq,adj,T.
AMBIENT NOISE LEVEL MEASUREMENTS
On Wednesday 13th November ambient noise levels were obtained from adjacent to Block 3, the closest
residential to the Facilities Building. The results of these ambient noise level measurements are
detailed in Table 1 below.

The above ambient noise levels are lower than what would be expected for the density of residential
apartments in this complex. At the time of these ambient noise assessments very few (four) apartments
appeared to be occupied (gauged by whether at approximately 2120 hour or not there were any lights
on in the apartment at approximately 2120 hours) – three in Block 2, one in Block 3 and none in Block 4.
Block 14 is currently under construction and Blocks 18 to 21 – construction not yet commenced. Once
all of these apartments are constructed and occupied the ambient noise levels will be greater, including
the background sound level (LA90,T).
It is anticipated that, with all of the apartments occupied, the background sound levels will be:
daytime: 45 dB(A);
evening: 40 dB(A);
night (up to midnight): 35 dB(A).
In December 2019 (Monday 2 and Wednesday 18) evening background sound levels were obtained.
The early evening background sound level was 40 dB(A) LA90,T and the late evening background sound
level was 38 dB(A) LA90,T respectively, and these results support the above predicted evening
background sound level of 40 dB(A) and early night-time predicted background sound level of 35 dB(A).
In accordance with Condition 81 the associated plant and equipment noise limits will be:
daytime (0700 to 1900 hours): 50 dB(A);
evening (1900 to 2200 hours): 43 dB(A);
night (up to midnight): 38 dB(A).
PLANT AND EQUIPMENT
For the Facilities Building all of the plant and equipment is located on the roof plant deck. On the
western side of the plant deck a Sonic Series 100 acoustic louvre has been installed with an insertion
loss of:
63 Hz: -
125 Hz: 4 dB;
250 Hz: 5 dB;
500 Hz: 8 dB;
1000 Hz: 12 dB;
2000 Hz: 16 dB;
4000 Hz: 15 dB.
All sides of the roof top plant deck has differing height masonry nib walls, ranging from 800 mm to 1600
mm high.
The plant and equipment located on the plant deck is as follows:
kitchen exhaust fan;
Daikin RXYQ8AYM;
Daikin RXYQ16AYM (gymnasium);
Daikin RXYMQ4AV4A (two of);
Glacier GC 301-B-2.7 (two of);
MINT HUCE22-1M;
MINT HUCE-1L.

Measured Noise Levels
On Wednesday 13th November, during the early evening, source noise level measurements were
obtained, as all of the above plant and equipment has been commissioned and was operating (for the
purpose of assessing the noise level only). However, at this time the kitchen exhaust fan ductwork was
not connected to the rooftop cowl and the acoustic louvre had not been installed.
By late November 2019 the acoustic louvre was installed to the western side of the rooftop plant deck
and the kitchen exhaust fan connected to the roof cowl. On Monday 2 December 2019 a further noise
assessment was conducted, to determine the magnitude of noise reduction achieved by these further
works. The results of this further noise assessment, from the eastern (rear) boundary fence of Block 3,
with the microphone elevated 7.5 metres to be equivalent to the top floor of residential in Block 3) are as
follows.
During the ambient noise assessments (kitchen exhaust fan OFF) there was some limited domestic
noise from the closest occupied apartments, including people talking and televisions, with some distant
noise from the irrigation system watering the vegetated embankment to the east.

From the above results, for the early evening the average background sound level was 40 dB(A) LA90,T,
which is the same as the evening background sound level adopted to determine the evening noise limit.
By late evening/early night-time it would be expected that the background sound level could reduce to
as low as the adopted level of 35 dB(A) LA90,T.
On Wednesday 18 December 2019 a further noise assessment was conducted, to determine the
magnitude of noise reduction achieved if the kitchen exhaust fan speed is reduced to 50% - ‘low’. The
results of this further noise assessment, from the eastern (rear) boundary fence of Block 3, with the
microphone elevated 7.5 metres to be equivalent to the top floor of residential in Block 3) are as follows.

From the above results, for the late evening, the background sound level was 38 dB(A) LA90,T, providing
further support for the early night-time (2200 hours to midnight) adopted background sound level of a
conservative 35 dB(A) LA90,T.
With no Utilities Building plant and equipment audible and the kitchen exhaust fan turned off the
average ambient LAeq,5min noise level was 40.7 dB(A) LAeq,5min.
All noise level measurements were conducted 17 metres from the kitchen exhaust fan of the Utilities
Building, with the microphone elevated 7.5 metres to be equivalent to the upper level residential of
Block 3, which was a further 7 metres distant from the monitoring location. This additional separation
distance would result in a further 3 dB(A) noise level reduction.
With the kitchen exhaust fan at 75% the noise level of the kitchen exhaust fan would be:
46.0 dB(A) (measured level) – 40.7 (ambient noise level without exhaust fan) = 44.5 dB(A) – 3
(additional separation distance) = 41.5 dB(A) LAeq,T.
This complies with the daytime and evening noise limits but exceeds the night-time (up to midnight)
noise limit by 41.5 – 38 = 3.5 dB(A).
With the kitchen exhaust fan at 50% the noise level of the kitchen exhaust fan and ambient noise was
39.4 dB(A) LAeq,T, and without the kitchen exhaust operating the ambient noise only was 39.0 dB(A)
LAeq,T. There is insufficient difference between these two levels to determine kitchen exhaust fan noise
only at 50%, so conservatively the noise level of the kitchen exhaust fan at 50% has been assumed to
be 39.4 dB(A) LAeq,T (in actuality it would be less than this).
Therefore the noise level of the kitchen exhaust fan at 50% would be:
39.4 dB(A) (measured level) – 3 (additional separation distance) = 36.4 dB(A) LAeq,T.
This complies with the daytime, evening and night-time (up to midnight) noise limits.
For just the kitchen exhaust fan the noise limits are complied with provided:
daytime and evening – kitchen exhaust fan set to low (50%) or high (75%);
night-time – kitchen exhaust fan set to low (50%) only (or turned off).
For all other plant and equipment (refrigeration and air-conditioning) their noise levels comply with the
noise limits for the complete 24-hour day.
GYMNASIUM
There is potential for noise from within the gymnasium to impact the closest residential Block, in
particular Blocks 3 and 4. The gymnasium is fully air-conditioned and it has been assumed that it will
only be ever operated with all external openings closed.
From a previous noise assessment conducted inside a gymnasium for a 48-hour period the noise levels
were:
average up to 72 dB(A) LAeq,15min;
maximum up to 88 dB(A).
The noise limits for noise from the gymnasium, at the closest residential, is:
daytime (0700 to 1800 hours): 50 dB(A) LAeq,adj,T;
evening (1800m to 2200 hours): 45 dB(A) LAe,adj,T;
night-time (2200 hours to midnight): 40 dB(A) LAeq,adj,T.

Environmental Noise Level Impact Assessment of Facilities Building, Parkridge, 75 Resort Drive, Noosa Heads Page 10 of 16
The external structure of the gymnasium building will reduce noise levels from inside the gymnasium to
the closest residential as follows:
72 dB(A) LAeq,adj,15min – 20 (inside to outside gymnasium building, external; openings closed) –
10 (distance to closest residential apartment) = 32 dB(A) LAeq,adj,T.
Provided the external openings are closed noise from inside the gymnasium complies with the noise
limits for the complete 24-hour day.
DELIVERY VEHICLES
From previous noise assessments conducted of different commercial facilities, the typical noise of a
refrigerated delivery vehicle (up to 4.5 tonne) is 79 dB(A) LWA. This includes the truck arriving, doors
opening and closing, unloading, and departing.
The closest residential apartment to the loading bay/waste collection bay (bay 21, site plan refers) is
Block 3, Apartment T8, with a separation distance of approximately 15 metres (refer site plan, Figure 2
of this report). At this separation distance the noise of the delivery vehicle will be 79 dB(A) LWA – 32
(separation distance) = 47 dB(A) LAeq,adj,15min. This is a time varying noise source and complied with the
daytime noise limit of 50 dB(A) LAeq,adj,15min, but exceeds the evening and night-time noise limits of 40
and 45 dB(A) LAeq,adj,15min respectively.
To ensure compliance with the noise limits delivery vehicles should be limited to accessing the Facilities
Building during the daytime only, from 0700 to 1800 hours.
WASTE COLLECTION
From previous noise assessments conducted of waste collection vehicles (for wheeled plastic bins) the
typical noise level (adjusted to be equivalent to a 15-minute period) is 81 dB(A) LWA. This includes the
truck arriving, bins being emptied, and departing.
The closest residential apartment to the loading bay/waste collection bay (bay 21, site plan refers) is
Block 3, Apartment T8, with a separation distance of approximately 15 metres (refer site plan, Figure 2
of this report). At this separation distance the noise of the delivery vehicle will be 81 dB(A) LWA – 32
(separation distance) = 49 dB(A) LAeq,adj,15min. This is a time varying noise source and complied with the
daytime noise limit of 50 dB(A) LAeq,adj,15min, but exceeds the evening and night-time noise limits of 40
and 45 dB(A) LAeq,adj,15min respectively.
To ensure compliance with the noise limits waste collection vehicles should be limited to accessing the
Facilities Building during the daytime only, from 0700 to 1800 hours.
PATRON NOISE
The café and outdoor dining area will have a capacity of up to 150 diners and is proposed to trade from
0600 hours to midnight. During the early morning, from 0600 to 0700 hours, it is unlikely that there
would be more than approximately 30 diners present. During the daytime end evening there could be
up to the maximum capacity, namely 150 diners, and from 2200 hours to midnight it is unlikely that there
would be more than 100 diners.
From the architectural drawings approximately 25% of the outdoor dining area is not roofed and the
balance, 75%, is roofed.
The outdoor dining area and the café will be licensed for the consumption of alcohol, and this is
controlled by the Office of Liquor and Gaming Regulation (OLGR). It should be noted that as these
areas are licensed noise from patrons and amplified entertainment is under the control of OLGR.

Using the formula for patron noise LWA = 15 × log10(number of patrons) + 64 dB(A), then for the different
time periods the predicted patron noise levels would be:
0600 to 0700 hours: (15 × 1.48) + 64 = 86 dB(A) LWA for 30 diners and 82 dB(A) LWA for 15
diners;
0700 to 2200 hours: (15 × 2.18) + 64 = 97 dB(A) LWA for 150 diners and 92 dB(A) LWA for 75
diners;
2200 hours to midnight: (15 × 2.0) + 64 = 94 dB(A) LWA for 100 diners and 89.5 dB(A) LWA for 50
diners.
Closest Residential to East
The closest residential apartments with direct line of sight to the outdoor dining area are, at the time of
this report, still to be constructed, namely Blocks 18 to 21 inclusive. The floor level of these Blocks is
elevated at least 12 metres above the outdoor dining area, with Blocks 19 and 20 the closest, at a
separation distance of approximately 50 metres. At this elevation, and given that 75% of the outdoor
dining area is roofed, there would be line of sight to approximately 50% of the outdoor dining area and
the remaining 50% would be obscured from view by the roof. Therefore, for approximately 50% of the
outdoor dining area the roof acts as an acoustic barrier between the diners and the residential
apartment Blocks 18 to 21 inclusive.
At this separation distance (and allowing 50% protection to the outdoor dining area by the roof and
assuming 50% of the diners are under the roof and the other 50% are in the open) the above patron
noise levels would be:
0600 to 0700 hours: 82 dB(A) LWA – 42 (distance) = 40 dB(A) LAeq,adj,T with line of sight; and
82 dB(A) LWA – 42 (distance) – 8 (roof over) = 32 dB(A) LAeq,adj,T.
Combined noise level = 41 dB(A) LAeq,adj,T, less 7 dB(A) for the
residential balcony balustrade = 34 dB(A) LAeq,adj,T.
0700 to 2200 hours: 92 dB(A) LWA – 42 (distance) = 50 dB(A) LAeq,adj,T with line of sight; and
92 dB(A) LWA – 42 (distance) – 8 (roof over) = 42 dB(A) LAeq,adj,T.
Combined noise level = 51 dB(A) LAeq,adj,T, less 7 dB(A) for the
residential balcony balustrade = 44 dB(A) LAeq,adj,T.
2200 hours to midnight: 89.5 dB(A) LWA – 42 (distance) = 47.5 dB(A) LAeq,adj,T with line of sight;
and
89.5 dB(A) LWA – 42 (distance) – 8 (roof over) = 39.5 dB(A) LAeq,adj,T.
Combined noise level = 48 dB(A) LAeq,adj,T, less 7 dB(A) for the
residential balcony balustrade = 41 dB(A) LAeq,adj,T.
For the time varying noise of patrons laughing and talking the noise limits are:
daytime (0700 to 1800 hours): 50 dB(A) LAeq,adj,T;
evening (1800 to 2200 hours): 45 dB(A) LAeq,adj,T;
night-time (2200 to 0700 hours): 40 dB(A) LAeq,adj,T.
The daytime and evening noise limits are complied with for the above scenarios, as is the early morning
period. However, the night-time period (2200 to midnight) is potentially exceeded by 1 dB(A). Given
that it is unlikely that there would still be 100 patrons in the outdoor dining area between 2200 hours and
midnight on a regular basis, this minor exceedance should be considered acceptable.
In addition to the above it should be noted that there will be clear plastic blinds installed around the
perimeter of the roofline for the outdoor dining area and when these curtains are closed they will assist,
to a small extent, in further reducing any potential noise impact to the closest residential.

Closest Residential to North
The next closest residential apartments with direct line of sight to the outdoor dining area are to the
north – Block 14, and to the north-north-west, Block 2. Block 14 is approximately 75 metres from the
outdoor dining area and has line of sight to approximately 80% of the outdoor dining area. Block 2 is
approximately 50 metres from the outdoor dining area and has line of sight to approximately 60% of the
outdoor dining area.
Block 14
At a 75 metre separation distance the patron noise levels would be:
0600 to 0700 hours: 85 dB(A) LWA – 46 (distance) = 39 dB(A) LAeq,adj,T with line of sight, less
7 dB(A) for the residential balcony balustrade = 32 dB(A) LAeq,adj,T.
0700 to 2200 hours: 95 dB(A) LWA – 46 (distance) = 49 dB(A) LAeq,adj,T with line of sight less
7 dB(A) for the residential balcony balustrade = 42 dB(A) LAeq,adj,T.
2200 hours to midnight: 92.5 dB(A) LWA – 46 (distance) = 46.5 dB(A) LAeq,adj,T with line of sight,
less 7 dB(A) for the residential balcony balustrade = 40 dB(A) LAeq,adj,T.
For the time varying noise of patrons laughing and talking the noise limits are:
daytime (0700 to 1800 hours): 50 dB(A) LAeq,adj,T;
evening (1800 to 2200 hours): 45 dB(A) LAeq,adj,T;
night-time (2200 to 0700 hours): 40 dB(A) LAeq,adj,T.
The daytime, evening and night-time noise limits are complied with for the above scenarios, for Block
14.
Block 2
At a 50 metre separation distance the patron noise levels would be:
0600 to 0700 hours: 83 dB(A) LWA – 42 (distance) = 41 dB(A) LAeq,adj,T with line of sight, less
7 dB(A) for the residential balcony balustrade = 34 dB(A) LAeq,adj,T.
0700 to 2200 hours: 93 dB(A) LWA – 42 (distance) = 51 dB(A) LAeq,adj,T with line of sight less
7 dB(A) for the residential balcony balustrade = 44 dB(A) LAeq,adj,T.
2200 hours to midnight: 90.5 dB(A) LWA – 42 (distance) = 48.5 dB(A) LAeq,adj,T with line of sight,
less 7 dB(A) for the residential balcony balustrade = 41 dB(A) LAeq,adj,T.
For the time varying noise of patrons laughing and talking the noise limits are:
daytime (0700 to 1800 hours): 50 dB(A) LAeq,adj,T;
evening (1800 to 2200 hours): 45 dB(A) LAeq,adj,T;
night-time (2200 to 0700 hours): 40 dB(A) LAeq,adj,T.
The daytime and evening noise limits are complied with for the above scenarios, as is the early morning
period. However, the night-time period (2200 to midnight) is potentially exceeded by 1 dB(A). Given
that it is unlikely that there would still be 100 patrons in the outdoor dining area between 2200 hours and
midnight on a regular basis, this minor exceedance should be considered acceptable.

In addition to the above it should be noted that there will be clear plastic blinds installed around the
perimeter of the roofline for the outdoor dining area and when these curtains are closed they will assist,
to a small extent, in further reducing any potential noise impact to the closest residential.
Closest Residential to West
The closest residential apartments to the west have no line of sight to the outdoor dining area, with the
closest residential in this direction being Block 3 at a distance of approximately 40 metres. The
intervening roof of the Facilities Building provides a noise reduction of approximately 14 dB(A).
At a 40 metre separation distance the patron noise levels would be:
0600 to 0700 hours: 86 dB(A) LWA – 40 (distance) – 14 (roof acting as acoustic barrier) = 32
dB(A) LAeq,adj,T, less 3 dB(A) for the residential balcony balustrade = 29
dB(A) LAeq,adj,T.
0700 to 2200 hours: 97 dB(A) LWA – 40 (distance) – 14 (roof) = 43 dB(A) LAeq,adj,T, less 3
dB(A) for the residential balcony balustrade = 40 dB(A) LAeq,adj,T.
2200 hours to midnight: 94 dB(A) LWA – 40 (distance) – 14 (roof) = 40 dB(A) LAeq,adj,T, less 3
dB(A) for the residential balcony balustrade = 37 dB(A) LAeq,adj,T.
For the time varying noise of patrons laughing and talking the noise limits are:
daytime (0700 to 1800 hours): 50 dB(A) LAeq,adj,T;
evening (1800 to 2200 hours): 45 dB(A) LAeq,adj,T;
night-time (2200 to 0700 hours): 40 dB(A) LAeq,adj,T.
The daytime, evening and night-time noise limits are complied with for the above scenarios, for Block 3.
AMPLIFIED MUSIC
At the time of preparing this report no detail was available with respect to speaker locations. It has been
assumed that all speakers would be located immediately under the solid roof of the outdoor dining area,
and angled down as much as possible – area delineated by red rectangle in Figure 2.
It should also be noted that the café and outdoor dining areas will be licensed for the consumption of
alcohol and, as such, the noise of amplified entertainment will be controlled by the Office of Liquor and
Gaming Regulation, together with patron noise. OLGR will require a separate noise impact assessment
of amplified entertainment based on actual source noise level measurements conducted concurrently
from 3 metres from the speakers and at the closest sensitive receptors – in this situation the closest
residential apartments.
The amplified entertainment noise limits nominated below are based on calculation only and should be
considered preliminary, as actual amplified music noise level measurements will provide the required
level of detail to determine the actual amplified entertainment noise limits.
Based on the patron noise impact calculations the preliminary amplified music noise limits for the in-
house speaker system for amplified music should be the same as for patrons, but +5 dB to allow for the
additional barrier effect of the roof and the fact that these speakers will be located just below the line of
the ceiling.
Therefore the preliminary amplified music noise limits for the in-house speakers, located within the red
rectangle in Figure 2, are:
daytime and evening (0700 to 2200 hours) = 92 dB(A) LWA, which is equivalent to 75 dB(A) + 5
= 80 dB(A) LAeq,adj,T at 3 metres from the speakers;

Altum Constructions
Environmental Noise Level Impact Assessment of Facilities Building, Parkridge, 75 Resort Drive, Noosa Heads Page 14 of 16
night-time (0600 to 0700 hours and 2200 hours to midnight) = 88 dB(A) LWA, which is equivalent
to 71 dB(A) + 5 = 76 dB(A) LAeq,adj,T at 3 metres from the speakers.
In addition to the above any live performer must be required to play through the in-house system. No
speakers (in addition to the in-house system) are to be permitted on site.
NOISE CONTROL
The noise limits adopted in this noise impact assessment report for the Facilities Building are:
Steady state noise:
daytime (0700 to 1900 hours): 50 dB(A) LAeq,adj,T;
evening (1900 to 2200 hours): 43 dB(A) LAeq,adj,T;
night-time (2200 hours to midnight): 38 dB(A) LAeq,adj,T;
time varying noise:
daytime (0700 to 1800 hours): 50 dB(A) LAeq,adj,T;
evening (1800 to 2200 hours): 45 dB(A) LAeq,adj,T;
night-time (2200 hours to midnight): 40 dB(A) LAeq,adj,T.
All of the noise level impact calculations detailed in this report are to the closest residential external
living areas, namely balconies or courtyards. In consideration of the potential for noise impact inside
the residential apartments, this will be significantly less due the fact that all habitable rooms of all
apartments are fully air-conditioned, enabling external openings to be closed and maintaining an
acceptable level of temperature comfort inside the apartment. Additionally, all sliding glass doors are
fitted with 6 mm thick toughened glass with an Rw 28 to 30. For Block 3 (at least), where there is also
fixed panes of glass above the sliding glass doors to access the balconies, these have 6 mm float glass
with a similar Rw to the sliding glass doors.
In accordance with the Council approval, the following noise control measure requirements should be
noted:
82. The development shall comply with the noise management strategies contained in the report
prepared by Ron Rumble Pty Ltd and dated November 2006, with the following additional
details to be provided prior to issue of Operational Works to the reasonable satisfaction of
Manager, Environmental Health Noosa Council: -
83.1 The necessary and appropriate noise control measures incorporated into the façade of
the apartments and within the restaurant. These measures shall include:
83.1.1 Upgraded glazing and air-conditioning to the potentially affected apartments;
83.1.2 Strategically placed wing walls on balconies to screen the apartment and
balconies from alfresco dining areas;
83.1.3 Installation of a roof over the outdoor dining area with absorption to the
underside should be explored;
83.1.4 Revised hours of operation to no later than midnight;
83.2 Formulate and implement a Noise Management Plan to deal with noise emissions from
the premises including patron noise.
83.3 The applicant must advise prospective purchasers that a noise management plan has
been prepared to manage noise emissions related to the development.
83.4 The Noise Management Plan referred to in Condition 83.2 shall be incorporated in
perpetuity in the By-Laws of the Body Corp for the building.

83.5 The Noise Management Plan shall include a process for dealing with complaints and
specify that the Restaurant Management and Body Corp Manager be responsible for
dealing with any noise complaints.
With respect to the above the following noise control measures are incorporated into the Facilities
Building and all of the closest residential apartments, as applicable. With respect to the calculation of
noise impact detailed in this report, the following noise control measures, as applicable, have been
taken into account:
1. roof over the outdoor dining area, accounting for approximately 75% of the total outdoor dining
area;
2. solid balustrades to residential balconies at least 1000 mm high;
3. solid full height (and full depth of balcony) masonry walls separating residential balconies and
acting as wing walls.
Specific to the above Conditions, the following comments should also be noted:
83.1.1: ALL residential apartments are fully air-conditioned (all habitable rooms) and glazing
facing the Facilities Building (for the closest Blocks, namely 2, 3 and 4, as well as 18 to
21) is 6 mm thick toughened glass for sliding glass doors and, for any windows above
the sliding glass doors, 6 mm float glass, both of which are thicker than what would
normally be installed when the original 2006 noise report was prepared.
83.1.2: Every residential apartment balcony has full height (and full depth of the balcony) end
walls (masonry construction) which are, effectively, wing walls for those apartments not
directly in line with the Facilities Building and in particular the outdoor dining area.
83.1.3: Approximately 75% of the outdoor dining area is roofed over, and for that part of the
roof closest to the café, approximately 75 m2 has acoustic absorbent panelling
incorporated into the ceiling lining. This represents approximately 50% of the primary
roofed area out from the café (but not including the additional awning which is roof only
– no ceiling lining).
83.1.4: The proposed trading hours are from 0600 to 2400 hours (6:00am to midnight).
83.2: A Noise Management Plan has been prepared.
83.5: The Noise Management Plan includes a process for dealing with any noise complaints.
Further to the above the following additional noise control measures are required:
1. Waste collection to only occur between 0700 and 1800 hours daily;
2. Delivery vehicles to only access the Facilities Building between 0700 and 1800 hours daily;
3. Gymnasium to only operate with all external openings (doors and windows) closed. The only
possible variation to this requirement would be for quiet activities within the gymnasium during
the daytime;
4. Preliminary amplified music noise limits are:
day and evening (0700 to 2200 hours): 80 dB(A) LAeq,adj,T at 3 m from the speakers;
night (up to midnight): 76 dB(A) LAeq,adj,T at 3 m from the speakers;
5. All speakers for amplified music must be located immediately under the solid roof of the outdoor
dining area, and angled down as much as possible.

6. Any live performer must be required to play through the in-house system. No speakers (in
addition to the in-house system) are to be permitted on site.
7. Plant and equipment (excluding the kitchen exhaust) can operate 24-hours per day, 7-days per
week.
8. Kitchen exhaust fan can be operated on ‘high’ (75%) from 0600 to 2200 hours. From 2200
hours to midnight the kitchen exhaust fan must only be operated on ‘low’ (50%), or turned off.
9. Access door into the rooftop plant deck (western side of plant deck) must be kept closed at all
times.
It is a requirement of Condition 82 (and to a lesser extent Condition 84) that a noise assessment of the
plant and equipment be conducted to confirm compliance with the noise limits. This plant and
equipment noise assessment was conducted on Monday 2 and Wednesday 18 December 2019. With
the kitchen exhaust fan operating on ‘high’ from 0600 to 2200 hours and then, from 2200 hours to
midnight, operating at ‘low’ (50%), together with all other plant and equipment operating 24-hours per
day, all of the steady state noise limits are complied with.
CONCLUSIONS
The Facilities Building of Parkridge is located at 75 Resort Drive, Noosa Heads. The proposed hours of
operation for this Facilities Building are 0600 hours to midnight, daily. Potential noise impacts from the
Facilities Building include:
1. delivery vehicles;
2. waste collection vehicles;
3. plant and equipment;
4. patron noise;
5. amplified music.
The closest residential to the Facilities Building are:
Block 3 to the west;
Block 2 to the north-north-west;
Block 14 to the north;
Blocks 18, 19, 20 and 21 to the east.
