1. INTRODUCTION
Trinity Consultants Australia (previously known as ASK) was commissioned by GH Properties to provide
acoustic consultancy services for the proposed 106 room hotel to be located at Noosa Springs Resort, Noosa
Heads.
An acoustic report was previously prepared to accompany a Development Application for consideration by
Noosa Council for a development permit for a material change of use and preliminary approval to carry out
building work for extensions to tourist accommodation purposes. The application was made over land at
Resort Drive, Noosa Springs QLD 4567, and described as Lot4 SP178340.
In September 2022, Trinity was made aware of two changes that required consideration in the assessment:
◼ A vacuum pump truck will extract grease from the underground grease trap at approximately number 23
shown in Figure 3.1. We are informed pumping out the grease trap will take 15 to 30 minutes and is
likely to occur once every two months.
◼ Linen Deliveries may also occur on 3 occasions each week via the service road at approximately number
“23” shown in Figure 3.1.
An updated acoustic report 207401.0104.R01V04, dated 19 September 2022, was provided by Trinity to
address the above listed operational activities. The project has undergone several more changes (design
modifications) since then, and this acoustic report has been prepared to these changes. The changes to the
design are documented below:
◼ Changes to Tennis Court location.
◼ Changes to carpark activity.
◼ Loading dock and delivery / collection vehicle movement
Further review of potential approaches to address grease trap truck pump noise has been undertaken
in Section 6.2.4.1. Considerations for relaxed noise limits to account for the infrequency of the
pump’s usage have been also provided.
To incorporate the above changes, another updated acoustic report 207401.0104.R01V05, dated 1 November
2024, was provided by Trinity. This report version 6 was prepared to update project drawings only. It is noted
that changes in projects drawings are minor (e.g. removing a floor level on some buildings), and do not have
an impact on noise predictions.
The purpose of this report is as follows:
◼ Outline the relevant project noise criteria.
◼ Update noise impact assessment based on the changes made to the design.
◼ Describe noise mitigation requirements, if any.
To aid in the understanding of the terms in this report a glossary is included in Appendix A.

4. NOISE MEASUREMENTS
4.1 Overview
Acoustic measurements were obtained from the previous iteration of the report (207401.0104.R01V04, dated
19 September 2022). The measurements consisted of an attended noise measurement and noise logging. The
noise measurement location A is shown in Figure 2.1. Location A was located on the natural slope
(approximately one metre above tennis court level) at the south-east corner of the development area.
The noise monitoring was undertaken in general accordance with Australian Standard AS1055 Acoustics –
Description and measurement of environmental noise and the EHP Noise Measurement Manual 2013.
4.2 Attended Noise Measurement
An attended noise measurement was undertaken at Location A. The measurement was undertaken at 12:52pm
on 24th August 2020 over a 15-minute period using a field and laboratory calibrated Norsonic N140 Type 1
Environmental 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, 28 oC, nil cloud cover and
nil wind.
The measured noise levels are summarised in Table 4.1.

Cars on Resort Drive: 35-45 dBA
Groundskeeper shovelling: 37 dBA
Cement Truck: 41-55 dBA
Motorbike: 43-45 dBA
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.
4.3 Noise Logging
Noise logging was undertaken at Location A. Logging was undertaken from 25 August 2020 to 2 September
2020 using a field and laboratory calibrated Larson Davis LD831 Type 1 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 with no rainfall. Overall, the noise monitoring data is considered acceptable for use
in this report.
The measured noise levels are shown in Figure 4.1.

5.3 Environmental Protection Act
In Queensland, the environment is protected under the Environmental Protection Act 1994.
Section 3 of the EP Act states that the object of the Act is to protect Queensland’s environment while allowing
for development that improves the total quality of life, both now and in the future, in a way that maintains
the ecological processes on which life depends (ecologically sustainable development).
Section 319 of the EP Act relates to General Environmental Duty and states that a person must not carry out
any activity that causes, or is likely to cause, environmental harm unless the person takes all reasonable and
practicable measures to prevent or minimise the harm.
Section 14(1) of the EP Act defines environmental harm as any adverse effect, or potential adverse effect
(whether temporary or permanent and of whatever magnitude, duration or frequency) on an environmental
value, and includes environmental nuisance.
Section 15 of the EP Act defines environmental nuisance as an unreasonable interference or likely interference
with an environmental value caused by noise.
Section 440 of the EP Act relates to the offence of causing a nuisance, and section 440T, 440U and 440V
relates to the offence of contravening a noise standard. In all cases, the sections state it does not apply to an
environmental nuisance of the variety mentioned in schedule 1, part 1 of the EP Act.
This Act refers to the Environmental Protection Policies as being subordinate legislation to the Act.
The Act describes a number of offences relating to noise standards, including building work, regulated devices
(e.g. power tools), pumps, air-conditioning equipment, refrigeration equipment, indoor venues, outdoor
events, amplifier devices other than at indoor venue or open-air event, power boat sports in waterway,
operating power boat engine at premises, blasting, and outdoor shooting ranges. The relevant standards are
included below.
5.3.1 440U Air-conditioning equipment
1. This section applies to premises at or for which there is air-conditioning equipment.
2. An occupier of the premises must not use, or permit the use of, the equipment on any day—

a. before 7a.m, if it makes a noise of more than 3dBA above the background level; or
b. from 7a.m. to 10p.m, if it makes a noise of more than 5dBA above the background level; or
c. after 10p.m, if it makes a noise of more than 3dBA above the background level.
5.3.2 440V Refrigeration equipment
3. This section applies to a person who is—
a. an occupier of premises at or for which there is plant or equipment for refrigeration
(refrigeration equipment); or
b. an owner of refrigeration equipment that is on or in a vehicle, other than a vehicle used or to
be used on a railway.
4. The person must not use, or permit the use of, the refrigeration equipment on any day—
a. before 7a.m, if it makes a noise of more than 3dBA above the background level; or
b. from 7a.m. to 10p.m, if it makes a noise of more than 5dBA above the background level; or
c. after 10p.m, if it makes a noise of more than 3dBA above the background level.
5. In this section—
vehicle includes a trailer.
5.4 Environmental Protection (Noise) Policy
5.4.1 Overview
In respect of the acoustic environment, the object of the Act is achieved by the Environmental Protection
(Noise) Policy 2019 (EPP (Noise)). This policy identifies environmental values to be enhanced or protected,
states acoustic quality objectives, and provides a framework for making decisions about the acoustic
environment.
5.4.2 Background Creep
The EPP(Noise) identifies that background creep is to be prevented or minimised. Background creep is defined
as a gradual increase in the total amount of background noise in the area of place as measured under the
document called the ‘Noise measurement manual’.
Unlike the former 2008 EPP(Noise), there are no specific criteria proposed for the control of background creep.
It is therefore proposed to refer to noise criteria that have been used over a number of decades in Queensland
and are still used in the EP Act as offence criteria for mechanical plant, i.e.
◼ From 7am to 10pm, noise (inclusive of background noise) is to be no more than 5 dBA above the
background level.
◼ Before 7am or after 10pm, noise (inclusive of background noise) is to be no more than 3 dBA above the
background level.
5.5 Summary of Criteria
The proposed noise criteria are the background creep criteria, as follows:
◼ from 7am to 10pm, noise (LAeq,adj,T inclusive of background noise) is to be no more than 5 dBA above the
background level (LA90,T).
◼ before 7am or after 10pm, noise (LAeq,adj,T inclusive of background noise) is to be no more than 3 dBA
above the background level (LA90,T).
207401.0104.R01V06 Page 8
Page 12
◼ For the purposes of this project, a noise limit of 3 dBA above the background level (LA90,T) has been
adopted for all periods of the day.
It is considered that compliance with the nominated background creep criteria will result in compliance with
Noosa Council performance outcomes PO21 and PO22, that is:
◼ Provide a high level of amenity to users of the subject site, and do not unreasonably impact on the
amenity enjoyed by users of adjoining or nearby premises, including privacy and access to sunlight.
◼ Do not have an adverse effect on the amenity enjoyed by users of adjacent or nearby premises through
emission of noise

6. NOISE ASSESSMENT
6.1 Noise Limits
The project noise criteria were outlined in Section 5.5, and the noise limits can be determined based on the
noise monitoring results in Section 4. It is proposed that the nearest residences to the proposed development
be assessed based on the background noise levels measured at Location A. The noise limits are calculated as
shown in Table 6.1.
Table 6.1: Noise Limits

Evening (6pm to 10pm) 31 36 34
Night (10pm to 7am) 28 31 28
6.2 Noise Modelling
Noise from Noosa Springs Boutique Hotel has been modelled in SoundPLAN 8.2 as multiple point and line
sources. The tennis court and pool noise have been modelled as point sources and carpark activity has been
modelled as both point and line sources to indicate the impact of door slams and vehicle movement on nearby
receptors. Receptor R1 has been modelled as a third storey façade on the future development, this site was
chosen due to its proximity and elevation and can be considered the worst affected location on the future
development. Receptor R2 and R3 have been modelled as the façade of the house to the north west and south
west respectively as per Figure 2.1.
6.2.1 Tennis Noise Assessment
The tennis courts have undergone a few changes throughout the development of the design. Three tennis
courts were previously located further to the north east (See Figure 3.1). The new design adds one extra
tennis court and relocates all of them to the position illustrated in Figure 6.1.
This report compares the results from Trinity Report 207401.0104.R01V04, dated 19 September 2022 (three
courts in total, approximate location as shown in Figure 3.1) to the current design. It is understood that the
courts are to be used during the day and evening periods i.e. 7:00 am to 9:00 pm (The Noosa Shire Council
requires any communal outdoor facilities to not used between the hours of 9:00 pm and 6:30 am the following
day).
Noise emission levels from the proposed tennis courts have been calculated based on a sound power level of
92 dBA Leq per court based on tennis noise sourced from Trinity’s noise source database. Tennis activity was
modelled as a point source at the middle of each tennis court, as illustrated in Figure 6.1. The noise emission
results at each receptor can be found in Table 6.2.
Table 6.2: Tennis Court Noise Level Predictions
Sensitive Receiver Predicted Leq dBA Changes in Noise Levels dBA

Criteria 39 day / 34 evening
207401.0104.R01V06 Page 10
Page 14
Figure 6.1: Tennis Court Noise Model
As can be seen in Table 6.2 the tennis noise levels at the sensitive receivers are predicted to comply with the
daytime limit (39 dBA) for all 3 receivers. The noise limit for the evening limit is exceeded by 2 dBA at R1 and
R3, and exceeded by 4 dBA at R2. Reducing tennis court use to two courts and one court respectively are
provided below:
Table 6.3: Tennis Court Noise Level Predictions with Reduced Use
Sensitive Receiver Predicted Leq dBA
Two Courts in Operation One Court in Operation
R1 32 31
R2 35 33
R3 33 29
As seen above, noise levels at R1 and R3 are compliant with the evening noise limit of 34 dBA. Noise levels at
R2 are 35 dBA when two courts are in use. Since the noise level is within 1 dBA of the noise limit it is considered
marginally compliant. Limiting court use to 1 court does not achieve compliance with night time criteria (28
dBA). Based on the results provided in Table 6.2 and Table 6.3, the following is recommended:
◼ Maintain operations as proposed (4 tennis courts) during daytime (7am to 6pm).
◼ Limits operations to two courts during the evening (6pm to 9pm).
◼ Do not allow tennis court use during nighttime (9pm to 7am).
It is also noted that the resort operators will need to manage tennis noise onto the subject development itself,
as is normal resort practice, and this impact will be greater than any offsite noise impacts.
207401.0104.R01V06 Page 11
Page 15
6.2.2 Pool Noise Assessment
The pool design has changed since the last iteration of the acoustic report (Trinity Report
207401.0104.R01V04, dated 19 September 2022). However, the removal of one hotel building (refer to
Figure 3.1) has the potential of increase noise levels at R1 (refer to Figure 2.1) due to reduced noise
shielding. The sound power levels of expected swimming activity are based on Trinity’s noise source database
and are as follows:
◼ Group of 10 people swimming 55 dBA
◼ Group of 20 people speaking with a ‘loud’ voice 84 dBA
◼ Group of 50 people speaking with a ‘loud’ voice 88 dBA
◼ Group of 13 people speaking with a ‘loud’ voice 81 dBA
The previous iteration of the model focuses on the worst case scenario of a group of 50 people speaking with
a loud voice. To provide a more realistic noise result, the noise source was split into 4 different groups of 13
people speaking with a loud voice. Each noise source was assigned to 1 of the 4 pools. The figure below
illustrates the change made to the model:
Figure 6.2: Changes in Pool Noise Assessment
The noise emission results are shown in Table 6.4.

4x Point Sources – Group of 13 people speaking with a

‘loud voice’ each
From the results presented in Table 6.4, all pool activity sources are predicted to comply at residential
sensitive receivers R1, R2 and R3 with the day and evening noise limits.
It is noted that the resort operators will need to manage pool noise onto the subject development itself, as is
normal resort practice, and this impact will be greater than any offsite noise impacts.
6.2.3 Carpark Activity
The proposed development will include additional car parking spaces to the west of the site (above an existing
carpark) and two smaller car parks in the east of the site (for overflow purposes). Existing carparks on site
207401.0104.R01V06 Page 12
Page 16
will be retained, which will see increased activity for the purpose of the hotel and its noise level has been
adjusted accordingly to reflect the increased usage. Data used for modelling noise levels is below:
◼ Carpark movement (#13  in Figure 3.1): 73.7 dBA Lw,eq (15 km/h, 0.5m height)
◼ Carpark movement (#34 (North) in Figure 3.1): 55.0 dBA Lw,eq (15 km/h, 0.5m height)
◼ Carpark movement (#15 & #34 (South) in Figure 3.1): 62.9 dBA Lw,eq (15 km/h, 0.5m height)
◼ Door slams (2 slams per spot per hour): 53.9 dBA Lw,eq (1m height)
◼ The number of vehicle movements used in the calculations is the total number of car movements per car
spaces with half entering and half leaving in an hour period.
It is noted that any door slam carpark activity that is enclosed or located underground has been omitted from
the model since the noise contribution from those carparking spots is expected to be negligible. The modelled
noise sources are illustrated in Figure 6.3.

The carparking noise has been modelled and the noise emission results are shown in Table 6.5. While the
previous report assessed each carpark section individually, this report will assess the cumulative impact of all
carpark activity on the nearby receivers.

As seen in Table 6.5, noise generated by the carparks are predicted to comply with the anointed noise limits.
Additionally, the carpark noise model is somewhat conservative as it assumes equal levels of activity during
207401.0104.R01V06 Page 13
Page 17
all time periods. Realistically, night time activity will be less frequent than daytime and as a result is predicted
to yield lower noise levels.
6.2.4 Deliveries and Waste Collection
It is understood that the deliveries and waste collection activities will be completed from the existing country
club. Deliveries will be dropped off at the existing country club and then transported up the hill to the proposed
development. Waste will be collected and transported down the hill to the existing country club for overall
collection. GH Australia has noted that the transporting of goods will be done via electric motorised golf carts
and the expected noise levels would be relatively low.
With the deliveries and waste collection activities occurring at the existing clubhouse, it is not expected the
increase in these activities would have a significant noise impact. Deliveries and waste collection activities are
still suggested to be limited to daytime hours 7am to 6pm. The activities are described as follows:
◼ A vacuum pump truck will extract grease from the underground grease trap at approximately number
23 shown in Figure 3.1. We are informed pumping out the grease trap will take 15 to 30 minutes and is
likely to occur once every two months. The assessment for the vacuum pump truck can be found in
Section 6.2.4.1.
◼ Linen Deliveries may also occur on 3 occasions each week via the service road at approximately number
“23” shown in Figure 3.1. A sound power level of 98 dBA for the delivery vehicle has been adopted with
a period sound power level LW,eq of 61 dBA, which is based on 2 movements (to and from) and a speed
of 10-40 km/hr. It was found that the linen truck delivery had no adverse effects on the predicted noise
levels at R1, R2 or R3.
6.2.4.1 Waste Collection – Grease Pump
It is understood that a grease trap located at the hotel loading dock area requires emptying every 1 to 2
months to remove any residue. This involves bringing in a pump truck that is equipped with a vacuum pump
to clear the grease in the trap. The sound power levels produced by the vacuum pump were provided by
Haztek. The sound power level and calculated sound pressure levels at 1m can be found in Table 6.5.
Table 6.6: Vacuum Pump Sound Levels
Source Sound Pressure Level (LAeq) Calculated Sound Power Level
(Lweq)
Vacuum Pump H400W (5m away) 84 112.3
Vacuum Pump H400W (10m away) 80 112.8
Vacuum Pump H400W (15m away) 77 112.7
When the sound power levels in Table 6.5 are averaged, the resultant sound pressure level comes to be
112.6 dBA. The vacuum pump was added to the model and its impact on nearby receivers has been
documented in Table 6.6.
Table 6.6: Vacuum Pump Noise Level Predictions
Receiver Predicted Noise Levels with Vacuum Pump
Day
R1 65
R2 37
R3 33
As seen in Table 6.6, the presence of the vacuum pump results in compliant noise levels at receivers R2 and
R3. On the other hand, receiver R1 experiences noise levels up to 65 dBA, which is 26 dBA above the 39 dBA
207401.0104.R01V06 Page 14
Page 18
limit. Given the infrequent occurrence of vacuum pump operations (15 to 30 mins every 1-2 months), a relaxed
noise limit could be considered. After further review following the previous reports, noise limits could consider:
◼ Background plus 10 dBA (equivalent to 46 dBA) – commonly adopted for short-term construction activities
and
◼ A fixed limit such as the Environmental Protection (Noise) Policy 50 dBA outdoor objective for a dwelling
◼ Existing LAeq noise levels – as per Table 4.2, max 58 dBA, top 10% 53 dBA, average 48 dBA, bottom
10% 43 dBA, min 39 dBA.
Potential noise measures may include barriers, enclosures or utilising trucks with quieter pumps. Also, given
the infrequent and short-term nature, an outcome may be to negotiate with the neighbouring townhouse a
suitable time for the pump operation to occur. These options for mitigation and management can be explored
further during subsequent design stages.
6.2.5 Road Traffic Noise Assessment
Road traffic noise for the site has been determined to be L10,18hr of 39 dBA in Trinity Report
207401.0104.R01V04, dated 19 September 2022. The building is exposed to noise levels that are below 57
L10,18hr dBA and as such is denoted as Category 0 under MP4.4 criteria. Standard construction is considered to
be acceptable for Category 0 and therefore no acoustic façade requirements are needed for the building.
6.2.6 Mechanical Plant Noise Assessment
At this stage the mechanical design is not complete and therefore it is proposed that plant is designed and
selected to achieve the above recommended design noise limits in Table 6.1. Consideration should also be
given to the construction of acoustic screening to plant where it may impact on residences.
6.2.7 Clubhouse Noise Assessment
The design includes changes to the layout existing clubhouse. The proposed changes are as follows:
◼ Replacement of old resort reception with new private dining / meeting facility.
◼ Replacement of old bar and coffee shop with new bar and café facilities.
◼ Replacement of old kitchen with new service kitchen facility.
◼ Addition of the following spaces:
Liquor cold room
Dry store
Security & procurement office
Wet waste cool room
Dry waste storage room
Enclosed storage area.
As seen above, the clubhouse changes involve the addition of new dining/meeting facilities, upgrade of existing
catering facilities and addition of storage space. These activities generate low levels of noise relative to other
noise sources on site. Additionally, the clubhouse is fully enclosed, which will heavily mitigate noise levels
generated from the additional / upgraded spaces. As such, proposed clubhouse changes are predicted to be
compliant with the noise limits in Table 6.1.

7. RECOMMENDATIONS AND CONCLUSION
A noise assessment has been conducted for the proposed 83 room hotel to be located at Noosa Springs Resort,
Noosa Heads. The results and recommendations of the assessment are as follows:
◼ Noise limits for the project have been determined using the noise data captured for the previous phase
of the project. All relevant noise data can be found in Section 4.
◼ Tennis activity is addressed in Section 6.2.1. The main outcomes are summarised as follows:
The tennis courts have been relocated as shown in Figure 3.1. The noise model has been updated
to calculate noise levels unto nearby receptors based on the new tennis court locations.
While compliance with the daytime noise limit is achieved, exceedances are experienced at R2 and
R3 during evening and nighttime. The following is proposed to achieve compliance throughout the
day:
◼ Maintain operations as proposed (4 tennis courts) during daytime (7am to 6pm).
◼ Limits operations to two courts during the evening (6pm to 9pm).
◼ No tennis court use during nighttime (9pm to 7am).
◼ The pool activity assessment is detailed in Section 6.2.2. It is summarised as follows:
Pool activity was previously modelled as 1 point source at 1 pool location, with a SWL of 88 dBA.
This has been changed as 4 point sources with a SWL of 81 dBA, scattered across all pools (Refer
to Figure 6.2).
Compliance is predicted at all receiver locations, as shown in Table 6.4.
◼ The noise assessment of the carpark is detailed in Section 6.2.3. It is summarised as follows:
Noise levels have been mostly kept similar to the previous assessment in Trinity Report
207401.0104.R01V04, dated 19 September 2022, with some adjustments to reflect the increased
activity on-site due to the carpark expansion.
Compliance is predicted at all receiver locations, as shown in Table 6.5.
◼ The majority of deliveries and waste collection activities are expected to be occurring at the existing
clubhouse and hence have no significant noise impact. Deliveries and waste collection activities are
suggested to be limited to daytime hours 7am to 6pm as outlined in Section 6.2.4.
◼ Delivery / waste collection activity’s impact on the site is summarised as follows:
Delivery of linen trucked to the proposed development is predicted to have no impact on the noise
levels at R1, R2 and R3.
Collection of residual grease via a vacuum truck visiting the site once every 2 months has the
potential for adverse acoustic impacts on R1, with a predicted noise level of 65 dBA LAeq,15min. Given
the infrequent nature of vacuum pump operations (15-30 minutes per month) a relaxed noise limit
may be applied. Refer to Section 6.2.4.1 for discussion.
◼ Road traffic noise for the site is L10,18hr of 39 dBA (based on noise monitoring data from Trinity Report
207401.0104.R01V04, dated 19 September 2022). No acoustic façade requirements are needed to be
met under MP4.4 criteria.
◼ Mechanical plant is to be designed, selected and located to achieve the noise limits as outlined in
Table 6.1.
◼ The activities associated with proposed clubhouse layout changes generate low levels of noise relative to
other noise sources on site. Additionally, the clubhouse is fully enclosed, which will heavily mitigate noise
levels generated from the clubhouse. As such, proposed clubhouse changes are expected to be compliant
with the noise limits in Table 6.1.
Compliance with the above recommendations is predicted to result in compliance with relevant noise criteria.

APPENDIX A GLOSSARY
Parameter or Term Description
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.
Brisbane City Council 2014 City Plan and Moreton Bay Regional Council Noise Policy
additional definition:
Lmax assessment only applies to ‘specified noise sources’ which are defined as - (a)
impact noises; (b) hammering; (c) loading/unloading; (d) dropping items; (e) beepers,
alarms, bells, phones, sirens; (f) power tools; (g) valve releases; (h) air brakes; and (i)
door slamming. People noise and vehicle pass-by noise (engine, exhaust, induction,
tyres) are specifically excluded.
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).
Habitable Rooms According to the "Building Code of Australia" a Habitable Room is: " a room used for
normal domestic activities and
Includes a bedroom, living room, lounge room, music room, television room, kitchen,
dining room, sewing room, study, playroom, family room, home theatre, and sunroom,
but
Excludes a bathroom, laundry, water closet, pantry, walk-in wardrobe, corridor,
hallway, lobby, photographic darkroom, clothes drying room, and other spaces of a
specialised nature occupied neither frequently nor for extended periods."
Acoustic fence Solid, gap free fence with minimum panel surface density of 12.5kg/m2.
