NOISE IMPACT ASSESSMENT
1.0 INTRODUCTION
Blue Care are proposing to establish an integrated Aged Care Precinct on a site located on the
corner of Ben Lexcen Drive and Grass Tree Court, Sunrise Beach. The site locality is shown
on Sketch 1. Palmer Acoustics (Australia) Pty Ltd has been commissioned by Blue Care to
complete a noise impact assessment addressing noise issues associated with the development.
The report aims to address:
Noise intrusion onto the facility from nearby traffic infrastructure; and
Noise emission from the facility onto neighbouring noise sensitive locations.
This report has been prepared in accordance with the relevant codes of the Sunshine Coast
Regional Council Noosa Division.
1.1 Existing site and surroundings
The development is proposed for a site generally described as the south western corner of
Grass Tree Court and Ben Lexcen Drive. The Sunrise Beach Uniting Church is located to the
north west of the site. The site is currently vacant and slopes down from east to west. The
site is located near an existing small retail facility.
1.2 Proposed development
Blue Care are seeking to establish an integrated care precinct providing aged care from fully
independent living to supported care. When fully developed the site will provide:
Serviced Apartments;
Independent Living Units;
Residential Aged Care Facilities: and
Allied Health & Respite Services.
The proposed plans of the development are shown on:

NOISE IMPACT ASSESSMENT
2.0 EQUIPMENT AND PROCEDURES
2.1 Measurement Procedures
Environmental Noise loggers were placed on the site at locations ML1 and ML2. The
locations were chosen for exposure to the noise related to Church Activity, to traffic noise
from Ben Lexcen Drive and to capture the overall background noise levels of the site. The
logger locations are shown on Sketch 2. Noise logging was conducted over the period 22nd to
29th April (ML2) and 8th to 11th May 2008 (ML1.
2.2 Instrumentation
The following instruments were used to measure the ambient noise levels:
ARL-EL 215 No. 2 Environmental Noise Logger (serial number 194660)
ARL-EL 215 No.1 Environmental Noise Logger (serial number 194442)
Rion NC-73 Calibrator
The operation of the sound level measuring equipment was field calibrated before and after
each measurement session and was found to be within 0.1 dB of the reference signal. All
instrumentation used in this assessment has a current calibration certificate from a certified
NATA calibration laboratory.
3.0 AMBIENT NOISE LEVELS
The typical average ambient noise levels measured at ML2 are presented in Table 1. The
logger was located adjacent to a private dwelling on Ben Lexcen Drive as there was no secure
location on the site itself. The location was fully exposed to road traffic noise. The logger was
located approximately 27m from the running edge of Ben Lexcen Drive. Ambient noise
during the survey was composed of traffic and insect noise.

4.0 ROAD TRAFFIC NOISE
Ben Lexcen Drive is the largest road in the area and is not classed as a major road. The
logged data from the 23 and 24 of April was chosen as being representative of the road traffic
noise in the area; being free of non traffic noise, e.g. dog barking and weather. The results
have been averaged to produce the results presented in Table 4 below.

4.2 Noise Criteria
Under the Sunshine Coast Regional Council’s Noosa Region’s Transport, Roads and Drainage
Code road traffic noise is only to be considered where a residential development is adjacent to
a major road. It is noted that the noise levels recorded from the traffic noise on Ben Lexcen
Drive are below the levels limiting levels of the commonly accepted Department of Main
roads traffic noise limits at the facades of affected premises. If a traffic growth rate of 3.5% per
annum is assumed, a commonly accepted default value, the increase in traffic noise will be 1.8
dB over a 10 year period, the noise level is still below the DMR limits,
Accordingly the impact of road traffic noise on the development is not considered further.
5.0 MECHANICAL PLANT EMMISION NOISE
Designs for mechanical services have not yet been completed and plant selections and
locations are unknown. Therefore, we are only able to recommend design limits for the
control of mechanical plant noise emissions at the nearest noise sensitive receptor.
5.1 Noise Emission Criteria
Under the Sunshine Coast Regional Council’s Noosa Region’s Residential Uses Code Section
14.50 Overall outcomes for the Residential Uses Code stipulates:
g) provides residents with a high degree of privacy and protection from noise, lighting and other
environmental nuisances;
It is accepted that this objective is achieved if the noise emissions of mechanical plant,
measured at a noise affected place, are limited to the background noise levels plus a margin.
The criteria and resultant limits are presented in Table 5.
11 L Aeq (24 h our) refers to the equivalent of energy-averaged noise level averaged over a 24 hour period
12 LA90 (18 hour) refers to the noise level exceeded 90% of the time during the period 6:00 am and midnight
13 L A90 (8 hour ) for a specified time interval, means the arithmetic average of 8 individual L A90(1h our) levels measured between 10:00 pm and 6:00
am on the day

The Environment Protection Regulations (1998) presents offence limits for mechanical plant
noise emissions. This mechanical plant includes refrigeration equipment and air conditioning
equipment. The offence limits are shown in Table 6 and the derived limits are shown in Table
7.

Period Noise Limit
6 am – 6 pm 43 dB(A)
6 pm – 10 pm 40 dB(A)
10 pm – 6 am 34 dB(A)
5.2 Assessment
To comply with these limits, there are a number of engineering solutions available. Low
noise levels are achieved by the engineered selection and application of:
Low sound power level equipment
Silencers
Acoustic enclosures
Noise barriers
Vibration isolation systems
The application of such principles and treatments, along with providing maximum separation
distances between noise sources and sensitive areas will ensure that noise from plant and
equipment complies with limits.
For noise sensitive places within the development noise impacts from mechanical plant
should be engineered not to exceed 40 dB(A) when measured inside apartments.
14 LAma x,a dj,T is obtained by making adjustments for tonality and impulsiveness as specified in AS1055

NOISE IMPACT ASSESSMENT
6.0 INTERMITTENT AND FLUCTUATING NOISE
The development of the site includes several sources of intermittent and fluctuating noise that
may impact on adjacent and internal noise sensitive areas:
Service lane accesses for domestic vehicles;
Outdoor dining at the café, Ground level Central Facilities Building.
6.1 Criteria
The Sunshine Coast Regional Council’s Noosa Region’s codes do not have specific criteria for
intermittent and fluctuating noise emissions. It is considered relevant to apply the Brisbane
City Council ‘Noise Impact Assessment Planning Scheme Policy’ to assess day time
intermittent and fluctuating noise emissions. The criterion for intermittent and fluctuating
noise source from service lane and outdoor dining is pursuant to Section 6.2.1 of the NIAPSP,
‘Comparison of Like Parameters or Descriptors’. This methodology is used to assess noise
during the day time (0700 – 2200).
Under this criterion, the noise impacts at the façade of the building should not exceed the
existing ambient noise levels by more than 3 dB(A). The parameter chosen for this
assessment is average LAmax (0700 – 2200).
Section 6.2.3 of NIAPSP offers the criteria of ‘Sleep awakenings’ to assess night time noise
emissions. Further the Environmental Protection (Noise) Policy (EPP) provides guidance in
relation to control of noise impacts, excluding air conditioners and outdoor refrigeration
units, which are to be administered under the Environmental Protection Regulation 2005 Reprint
No 5:
The EPP does not state explicit criteria relating to intermittent noise; however guidelines for
assessing noise impact and criteria for reasonable and unreasonable noise are stated in the
Users Guide to the Noise Policy. The guidelines in the User’s Guide have been based on
World Health Organization guidelines and some Australian research. The guidelines
recommended are to achieve or maintain:
A continuous average (LAeq) level of 35 dB(A) indoors in a bedroom at night
(measured over the night-time period); and
For good sleep, a maximum level of 45 dB(A) to 50 dB(A) should not be heard
indoors more than 10 to 15 times a night.
The research concerning the effect of maximum noise levels of 45 to 50 dB(A) and number of
events is not complete and there is continuing discussion amongst people involved in
acoustics about the application of such criteria. This is because human response to noise
varies significantly from person to person, as to their adjustment to new noise sources. The
maximum level does not mean a person is awakened at these levels, but that sleep may be
disturbed. People may awaken at a higher maximum level of around 55 dB(A) in a quiet
environment.
From this we conclude:
A reasonable level of acoustic amenity is achieved by a design goal of a measured
maximum level of close to LAmax 45 to 50 dB(A) inside a bedroom, with an average
maximum LAeq level of close to 40 dB(A).
A high level of amenity is achieved by noise levels below 35 dB(A) LAeq and this
lower level is recommended should a high level of internal amenity be required.

GRASSTREE COURT, SUNRISE BEACH
NOISE IMPACT ASSESSMENT
Under this criteria noise from the surrounding land uses must not regularly exceed a LAmax . Adj
level of 45dB(A) inside a bedroom or sleeping area. From experience, including site
measurements, it is reasonable to apply an eight dB attenuation across (through) a façade
including open windows. Therefore the appropriate external criterion at the façade is 53
dB(A).
Table 8 :Day and night time noise limits
Period Measured Average LAmax Noise Limit at Façade
dB(A) LAmax dB(A)
Day time 7am - 10pm 62 65
Night time 10pm – 7am N/A 53
6.2 Service lane access
Vehicles travelling internally in the development have the potential to affect the rear of
dwellings located along Ben Lexcen and Columbia Drives: Lots 763 to 770 MCH805764. Table
9 sets out the predicted car noise levels for the service lane to the affected lots. A 5m setback
from the boundary has been assumed for the dwellings on the affected lots and a 5m
separation to the passing vehicle.
Table 9: Predicted car park noise impacts at eastern boundary dwellings
Source Noise at 10 m Noise Level Noise Level Complies With Noise
dB(A) @ 10m dB(A) at Façade Limits
Car pass by 61 dB(A) LAmax 61 dB(A) LAmax Day time only
It can be seen that the car pass by exceed the night time noise limit by up to 4 dB. Traffic
down the service lane is expected to be minimal given the expected occupant mix of the units.
However to ensure unrestricted compliance a 1.8m acoustic barrier fence is recommended
along the eastern boundary.
6.3 Outdoor dining
The Central Facilities Building incorporates a Bar/Café/function room area. The café area will
operate from 7am to 6pm, seven days. Outside these times the area may be used for
functions up to 12 midnight. It is expected that the café function will provide outdoor dining
and that any amplified entertainment employed will be at background levels only and will
not be provided for the outdoor area. The potentially most noise affected space is the closest
residential unit on Grass Tree Court, 40m from the edge of the terrace. The Residential Aged
Care building on the opposite side of Grass Tree Court is not considered noise affected. The
expected levels of noise from outdoor dining are presented in Table 10

SUNRISE BEACH RETIREMENT VILLAGE
GRASSTREE COURT, SUNRISE BEACH
NOISE IMPACT ASSESSMENT
From the limits presented in Table 3 we see that the expected impacts are significantly below
the expected background noise levels.
Noise emissions from the provision of amplified entertainment in the internal areas will be
governed by the provisions of the Liquor Act and the Liquor Regulation. During the detailed
design phase of the development the façade and structure of the facility will be detailed to
ensure that the desired level of amplified entertainment will be contained so that the required
limits are satisfied at the nearest noise sensitive location.
7.0 INTRUSION NOISE
The area surrounding the proposed development is residential or undeveloped with the
exception of the Sunshine Beach Uniting Church. The logged record at ML1 which included a
weekend does not indicate noise impact above the background noise at the expected nosiest
time at the start of Sunday services. See Sketch 7 for a graphical representation of the logged
record. Accordingly noise intrusion onto the site from the church and its associated activities
are not considered an issue.
8.0 CONCLUSIONS AND RECOMMENDATIONS
Based on the measurements and predictions presented, the following conclusions can be
drawn:
Road traffic Noise from Ben Lexcen Drive will impact on to the most affected facades of
the development at levels up to 57 dB LA10 18 hr :
With the inclusion of an acoustic barrier fence internal traffic noise levels impacts onto
adjacent residents can be controlled to be below ambient levels.; and
The site is not affected by noise intrusion from the adjacent church.
To ensure compliance with the requirements of The Sunshine Coast Regional Council for the
control of noise intrusion and emission the following is recommended:
An acoustic barrier fence be incorporated in to the development as indicated on Sketch 2.
Subject to the recommended acoustic treatments, it is the opinion of Palmer Acoustics (Australia)
Pty Ltd that the proposed development will generally comply with the requirements of The
Sunshine Coast Regional Council, Noose Division’s development codes.
