1 Introduction
ASK Consulting Engineers Pty Ltd (ASK) was commissioned by Palmlake Works Pty Ltd to provide
acoustic consultancy services for the proposed new townhouse development being constructed
at Trading Post Road, Cooroy.
This acoustic report is to accompany a Development Application for consideration by Noosa
Shire Council. The application is made over land described as Lot 1 on RP215922 and Lot 2 on
RP165418.
ASK has previously assessed the development in ASK report 4991R01V01, dated 12/03/2009.
Since that report the local authority has changed.
The proposed development includes 164 Independent Living Units for a proposed resort
development and a 120 bed proposed aged care development.
The purpose of this report is as follows:
Outline the relevant project noise criteria.
Present the results of noise monitoring.
Predict and assess the road and rail traffic noise impact onto the development.
Describe noise mitigation requirements, if any.
To aid in the understanding of the terms in this report a glossary is included in Appendix A.

Notes: Noise levels from railways or type 2 multi-modal corridors are to be measured in
accordance with AS1055.1–1997 Acoustics – Description and measurement of
environmental noise.
* ASK has been advised by SARA on 03/12/13 that it is acceptable to design residential
buildings beside a rail corridor to MP4.4 even if the rail corridor has not yet been
mapped as a transport noise corridor.
4.3 Department of Housing and Public Works – MP4.4
The Department of Housing and Public Works (HPW) has a number of mandatory Codes that
must be complied with at building application stage. These are referred to as Queensland
Development Codes (QDC). These codes previously only related to items such as energy
efficiency and water efficient fixtures in new residences.
7617R01V01.docx Page 12
Page 13
ACOUSTICS & AIR QUALITY
QDC Mandatory Part (MP) 4.4 relates to new buildings in transport noise corridors. This
mandatory Code deals with buildings within residential developments close to state-controlled
roads and railways. MP 4.4 sets mandatory construction standards for new residential
development, or additions to existing residential development, within a Transport Noise Corridor.
The Code is only intended to be applicable to gazetted Transport Noise Corridors, however, ASK
has been advised that it also applies to non-gazetted railway lines.
The noise level categories extend out to 57 dBA L10 (18 hour) for roads and 69 dBA Lmax for
railway lines.
4.4 Noosa Shire Council
The Noosa Shire Council Noosa Plan includes the following relevant noise requirements for
reconfiguration of a lot in Table 4.1.
Table 4.1 Noosa Shire Council Road and Rail Noise Criteria
Specific Outcome Probable Solution
14.193 Road and rail corridors
O31 Noise sensitive uses including residential S31.1 Noise sensitive uses including
uses are not subjected to high traffic noise residential uses are separated by a minimum
levels from the major road network or rail of—
corridors. a) 40m from the property boundary of roads
within the major road network; and
b) 80m from the property boundary of rail
corridors;
OR
S31.2 Development in the vicinity of road
corridors meets the following external design
criteria for roads in the major road network—
a) 54dBA L10 (18hours) based on predicted traffic
volumes ten years hence;
AND
S31.3 Development in the vicinity of rail
corridors meets the following external design
level noise criteria—
a) 65dBA, assessed as the 24hour average
equivalent continuous A-weighted sound
pressure level; and
b) 87dBA, assessed as a single event
maximum sound pressure level.
It is understood that the site does not comply with solution S31.1 and therefore should comply
with S31.2 and S31.3. However, a recent conversation with a Noosa Shire Council officer
regarding the road traffic noise criteria revealed a concern with the nominated limit. The
nominated limit of 54 dBA is significantly lower than the state road noise criteria and thus would
result in higher noise barriers, which we expect would be undesirable from Council’s perspective.
Therefore, with respect to road noise it is proposed to utilise the state road noise criteria.
7617R01V01.docx Page 13
Page 14
ACOUSTICS & AIR QUALITY
With respect to rail noise, the Council criteria in S31.3 match the state rail noise criteria
proposed previously.
4.5 Summary and Noise Limits
The relevant noise criteria for this development are:
Traffic noise (SDAP)
o At 1m outside buildings L10(18 hour) 60/63 dBA including façade reflection.
o For outdoor recreation areas L10(18 hour) 57/60 dBA excluding façade
reflection.
o For dwellings, apply the construction requirements in MP4.4 which correspond to
the external noise level categories.
Rail noise (SDAP)
o Lmax 87dBA and Leq (24 hour) average 65 dBA external level 1m from the façade.
o Lmax 84dBA and Leq (24 hour) average 62 dBA external free field level in private
open space and passive recreation areas.
o For dwellings, apply the construction requirements in MP4.4 which correspond to
the external noise level categories.

5 Acoustic Measurements
Acoustic measurements consisted of noise logging and a brief attended noise measurement.
5.1 Attended Noise Measurement
An attended noise measurement was undertaken at Location A as shown on Figure 2.1.
Location A was located on the fence line between the two southern-most at the designated site
on Trading Post Road, Cooroy.
The measurement was undertaken at 1pm on Wednesday 11th November, 2014, over a 15
minute period using a field and laboratory calibrated Norsonic NOR140 sound level meter. The
microphone height was approximately 1.3m above natural ground level and was located in the
free field. Weather during the time of monitoring was fine and warm, with no cloud cover.
The measured noise levels are summarised in Table 5.1. The parameters noted in Table 5.1 are
described in the glossary in Appendix A.

Noise from insects audible around 4 to 8 kHz
Note: * The reported noise levels, excluding the statistical noise levels, are the instantaneous levels
read from the sound level meter, and generally represent the range in noise levels or maximum
noise levels for a particular noise source.
5.2 Noise Logging
Noise logging was undertaken at Location A as shown on Figure 2.1. Logging was undertaken
from the 11th of November 2014 to the 19th of November 2014 using a field and laboratory
calibrated Larson Davis LD831 environmental noise logger. Noise logging was undertaken in
the free field.
Data from the Bureau of Meteorology (Brisbane) indicates that weather during the monitoring
period was generally fine and warm, but with light rainfall on Tuesday 18 th (2.8mm). Overall, the
noise monitoring data is considered acceptable for use in this report.
The measured noise levels are shown in Figure 5.1 and 5.2. The parameters graphed in Figure
5.1 and 5.2 are described in the glossary in Appendix A.

The single event maximum rail noise level at the monitoring location is determined as the
average of the noisiest 15 rail noise levels during any 24 hour period. The rail noise level has
been calculated using the average of the noisiest Lmax,15min values in each 24 hour period, with
the overall single event maximum rail noise level being taken as the median daily value. The
results are shown in Table 5.5.

Median Day 75.1
To check the validity of the above approach, ASK reviewed the noise level and audio data
associated with the maximum noise events on Day 1. It was determined that the average of the
noisiest 15 rail noise events was marginally lower than the average of the noisiest 15 overall
noise events, at 74.4 dBA Lmax versus 75.7 dBA shown in Table 5.5. Thus the approach used
in Table 5.5 is considered conservative as it is likely to marginally over predict the rail noise
exposure.
From the results in Figure 5.1, Table 5.2 to Table 5.5 and the observations noted from attended
measurements in Section 5.1 the following comments are made:
Road traffic is the consistent source of noise at this location.
Rail noise in inconsistent in comparison to traffic noise, however L max levels will be
dominant
Noise sources are Elm Road/Cooroy Connection Road, and Rail line adjacent to road.
Based on the measured background noise levels the outdoor road traffic noise limits are as
follows:
For the external facade of buildings L10(18 hour) 60 dBA including façade reflection.
For outdoor recreation areas L10(18 hour) 57 dBA free field.

6 Road Traffic Noise Assessment
6.1 Overview
Road traffic noise has been assessed from Cooroy Connection Road (Elm Street) onto the
proposed development. The relevant assessment criteria are outlined in Section 4.2.2.
TMR recommends that the prediction of road traffic noise is to be conducted according to the
United Kingdom Department of Transport (1988) procedure published as ”Calculation of Road
Traffic Noise” (CoRTN88). The road traffic noise levels have been predicted using the PEN3D
computer model, based on the CoRTN88 traffic noise prediction method and is approved by
TMR.
6.2 Data
The following data has been used in the noise calculations:
Noise source height of 0.5 m.
Ground contours for the site obtained from the Client onsite survey, field observations,
and Google Earth Pro.
It is understood that all residential dwellings will be single storey, and therefore a
receiver height of 1.8m above the provided pad levels has been used in the noise model.
Road width as per site inspection and Google Earth Pro images.
Traffic data shown in Table 6.1 has been obtained from TMR for Year 2012, and has
been adjusted for the years 2014 (existing) and 2024 (ten year planning horizon) using
a standard growth rate of 3.5% per annum.
The 18-hour traffic flow is taken to be 94% of the ultimate daily traffic flow.
The road surface for the roads is unknown but has been modelled as dense graded
asphalt (DGA) for validation purposes.
TMR CoRTN correction values of -0.7 dBA for free-field predictions and -1.7 for facade
corrected predictions have been used.
A +2.5 dBA facade reflection allowance is included in the road traffic noise level
predictions.

The results of the noise survey carried out at Location A have been used to verify the road traffic
noise model of Cooroy Connection Road (Elm Street).

Page 21
ACOUSTICS & AIR QUALITY
The road traffic verification model uses the 2014 traffic flow, as stated in Section 6.2 and
current road alignment to determine the L10(18hour). Table 6.2 compares the results obtained
from the noise survey with the calculated results from the computer model.
Table 6.2 Existing and Calculated Road Traffic Noise Level
Receptor Height Measured Noise Level Calculated Noise Level
metres L10(18 hour) dBA L10(18 hour) dBA
1.3m 55.9 56.8
The road traffic model is considered to be verified since the calculated level is within ± 2.0 dBA
of the measured level.
6.4 Calculations
The road traffic noise levels have been predicted for all retirement community allotments (refer
Figure 3.1 for numbering) and facade of the aged care building (refer Figure 3.2 for numbering).
The predicted Year 2024 L10(18hour) noise levels are listed in Table C.1.
From Table C.1 the highest predicted road traffic noise level is 71 dBA L10(18hour) in the
retirement community allotments and 66 dBA L10(18hour) outside the aged care building. All
other locations have lower levels of noise exposure. Based on the predicted noise levels the
MP4.4 Noise Categories in Table C.1 for road traffic noise are up to Noise Category 3.
The predicted L10(18hour) noise levels exceed the noise limits of 60 dBA (1m from the facade)
and 57 dBA (free-field) from Section 4.2.2, and therefore noise barriers are required. The
barriers required to achieve these criteria are 2.5m to 3.5m high as shown in Figure 6.1.
The predicted L10(18hour) noise levels with the proposed noise barriers are listed in Table D.1.
From Table D.1 the highest predicted road traffic noise level is 60 dBA L10(18hour) in the
retirement community allotments and 60 dBA L10(18hour) outside the aged care building. All
other locations have lower levels of noise exposure. The predicted L10(18hour) noise levels
comply with the noise limit of 60 dBA (1m from the facade) and 57 dBA (free-field) from Section
4.2.2 and therefore no additional noise barriers are required. Based on the predicted noise
levels the MP4.4 Noise Categories in Table D.1 for road traffic noise are up to Noise Category 1.
It is noted that the proposed noise barrier is very long and relatively high for what appears to be
a road carrying only minor to moderate traffic volumes. This is due in part to the strict noise
criterion being a quiet area, and the undulating terrain. It is noted that in the previous ASK
noise report for this site, the barrier height was restricted to 2.1m, resulting in higher noise
exposures at dwellings but accommodating this through more significant acoustic upgrades for
the dwellings. It is likely that any relaxation of the barrier height would require acceptance from
TMR and Council.
The noise barrier is mitigating noise from a TMR road and therefore it should comply with Main
Roads Technical Standard MRTS15 ‘Noise Fences’ dated April 2014. The noise barrier should
be solid and continuous with negligible holes or gaps, and achieve the TMR required density of
15 kg/m2.
A review of building construction requirements associated with the predicted MP4.4 noise
categories is included in Section 8.

7 Rail Noise Assessment
7.1 Overview
Rail traffic noise has been assessed from Sunshine Coast Line (Nambour and Gympie North
railway line) onto the proposed development. The relevant assessment criteria are outlined in
Section 4.2.3.
The rail noise levels have been predicted using the PEN3D computer model validated to onsite
noise measurements and is approved by TMR.
7.2 Data
The following data has been used in the noise calculations:
Ground contours for the site obtained from the Client onsite survey, field observations,
and Google Earth Pro.
It is understood that all residential dwellings will be single storey, and therefore a
receiver height of 1.8m above the provided pad levels has been used in the noise model.
The future rail noise levels are assumed to be equal to or lower than the existing rail
noise levels.
A +2.5 dBA facade reflection allowance is included in the rail noise level predictions.
7.3 Verification
The results of the rail noise survey carried out at Location A have been used to verify the rail
noise model.
The rail verification model uses the existing ground topography and current rail alignment to
determine the Lmax noise level. Table 7.1 compares the results obtained from the noise survey
with the calculated results from the computer model.
Table 7.1 Existing and Calculated Rail Noise Level
Receptor Height Measured Rail Noise Level Calculated Rail Noise Level
metres Lmax dBA Lmax dBA
1.3m 75.1 75.1
The rail noise model is considered to be verified since the calculated level matches the
measured level.
7.4 Calculations
The rail noise levels have been predicted for all retirement community allotments (refer Figure
3.1 for numbering) and facade of the aged care building (refer Figure 3.2 for numbering). The
predicted single event Lmax noise levels are listed in Table C.1.
7617R01V01.docx Page 23
Page 24
ACOUSTICS & AIR QUALITY From Table C.1 the highest predicted rail noise level is 82 dBA Lmax in the retirement community allotments and 80 dBA Lmax outside the aged care building. All other locations have lower levels of noise exposure. Based on the predicted noise levels the MP4.4 Noise Categories in Table C.1 for rail noise are up to Noise Category 3. The predicted Lmax noise levels comply with the noise limits of 87 dBA (1m from the facade) and 84 dBA (free-field) from Section 4.2.3 and Section 4.1, and therefore no noise barriers are required. However, a noise barrier has previously been proposed (refer Figure 6.1) and this can be included in the noise calculations. The predicted single event Lmax noise levels with the proposed noise barrier are listed in Table D.1. From Table D.1 the highest predicted rail noise level is 78 dBA Lmax in the retirement community allotments and 77 dBA Lmax outside the aged care building. All other locations have lower levels of noise exposure. Based on the predicted noise levels the MP4.4 Noise Categories in Table D.1 for rail noise are up to Noise Category 2. A review of building construction requirements associated with the predicted MP4.4 noise categories is included in Section 8. 7617R01V01.docx Page 24
Page 25
ACOUSTICS & AIR QUALITY
8 Internal Noise Assessment
The predicted noise levels shown in Tables C.1 and D.1 are used to determine the associated
noise category for each allotment or room facade based on Schedule 3, Table 1 of MP4.4 as
follows in Table 8.1.
Table 8.1 MP4.4 Noise Categories
MP4.4 Noise Category Rail Noise Level Road Traffic Noise Level
Lmax dBA L10(18hour) dBA
4 ≥ 85 ≥ 73
3 80 to 84 68 to 72
2 75 to 79 63 to 67
1 70 to 74 58 to 62
0 ≤ 69 ≤ 57
The MP4.4 classifications are included in Tables C.1 and D.1. From Table D.1, including the
noise barrier, it can be seen that the noise categories are up to Category 3, and are greater than
zero in most instances and therefore façade treatment is required to be assessed for these
rooms.
In accordance with MP4.4 the construction requirements are to be either (i) using construction
materials nominated in MP4.4, as described in Appendix E; or (ii) using construction materials
and methods that meet the minimum acoustic rating (Rw) requirements in MP4.4, as shown in
Appendix E, based on the manufacturers specifications.
To achieve the target noise reductions from external noise to internal noise levels in MP4.4 will
require the construction details are of an appropriate acoustic standard, and that all external
openings to be closed when these habitable rooms are occupied. Therefore, an air-
conditioning/mechanical ventilation system that does not degrade the internal acoustic
environment or the sound isolation of the building envelope, and also meets the ventilation
requirements of the Building Code of Australia may need to be installed.

9 Recommendations & Conclusion
A road and rail noise assessment has been conducted for the proposed retirement community
and aged care facility at Trading Post Road, Cooroy. The results and recommendations of the
assessment are as follows:
A noise barrier is proposed for the roadside boundary as shown in Figure 6.1. The
barrier is modelled as 2.0 metres to 3.5 metres high based on the proposed ground
levels provided to ASK. It is noted that the proposed noise barrier is very long and
relatively high for what appears to be a road carrying only minor to moderate traffic
volumes. This is due in part to the strict noise criterion being a quiet area, and the
undulating terrain. It is noted that in the previous ASK noise report for this site, the
barrier height was restricted to 2.1m, resulting in higher noise exposures at dwellings
but accommodating this through more significant acoustic upgrades for the dwellings. It
is likely that any relaxation of the barrier height would require acceptance from TMR and
Council.
To achieve the target noise reductions from external noise to internal noise levels in
MP4.4 will require the construction details are of an appropriate acoustic standard, and
that all external openings to be closed when these habitable rooms are occupied. The
required noise categories for all allotments and aged care home facades are included in
Table D.1, including the effect of the proposed noise barrier. The construction
requirements associated with these noise categories are included in Appendix E.
To achieve the target noise reductions from external noise to internal noise levels in
MP4.4 will require the construction details are of an appropriate acoustic standard, and
that all external openings to be closed when these habitable rooms are occupied.
Therefore, an air-conditioning/mechanical ventilation system that does not degrade the
internal acoustic environment or the sound isolation of the building envelope, and also
meets the ventilation requirements of the Building Code of Australia may need to be
installed.
Compliance with the above recommendations is predicted to result in compliance with relevant
noise criteria.

Appendix A Glossary
Parameter or Description
Term
dB The decibel (dB) is the unit measure of sound. Most noises occur in a range of
20 dB (quiet rural area at night) to 120 dB (nightclub dance floor or concert).
dBA Noise levels are most commonly expressed in terms of the ‘A' weighted decibel
scale, dBA. This scale closely approximates the response of the human ear,
thus providing a measure of the subjective loudness of noise and enabling the
intensity of noises with different frequency characteristics (e.g. pitch and tone)
to be compared.
Day The period between 7am and 6pm.
Evening The period between 6pm and 10pm.
Night The period between 10pm and 7am.
Free-field The description of a noise receiver or source location which is away from any
significantly reflective objects (e.g. buildings, walls).
L1 The noise level exceeded for 1% of the measurement period.
L10 The noise level exceeded for 10% of the measurement period. It is sometimes
referred to as the average maximum noise level.
L90 The noise level exceeded for 90% of the measurement period. This is
commonly referred to as the background noise level.
Leq The equivalent continuous sound level, which is the constant sound level over
a given time period, which is equivalent in total sound energy to the time-
varying sound level, measured over the same time period.
Leq,1hour As for Leq except the measurement intervals are defined as 1 hour duration.
Lmax Maximum A-weighted sound pressure level.
Leq(24 hour) The average Leq noise level over the 24-hour period from midnight to midnight.
L10(18 hour) The arithmetic average of the one-hour L10 values between 6am and midnight.
This parameter is used in the assessment of road traffic noise.
Rw Weighted Sound Reduction Index – is a single number evaluation of the
property of a partition to attenuate sounds. For the majority of partitions, the
value of Rw will be similar to the value for STC. Partitions with particularly poor
performance at 100 Hz may have lower values for Rw than for STC.
Conversely, partitions with poor performance at 4000 Hz may have higher Rw
than for STC. (As per AS1276.1-1999).
