1 INTRODUCTION

Rodney Stevens Acoustics Pty Ltd (RSA) has been engaged by Iris Capital to prepare a noise impact

assessment for the proposed additions and alterations to the existing Sportmans Hotel located at 81 Kildare

Road, Blacktown NSW 2148. This assessment forms part of the supporting documentation for DA submission

to Blacktown City Council.

The purpose of this report is to determine possible noise impacts on nearby receivers and if necessary provide

acoustic control recommendations so that the proposed additions and alterations may operate in an

acoustically compliant manner in accordance with Blacktown City Council’s requirements and Liquor and

Gaming NSW license conditions.

This report presents RSA’s methodology, assessment criteria and recommendations regarding patron and

operational noise emissions from the operation of the proposed additions and alterations.

Specific acoustic terminology is used in this report. An explanation of common acoustic terms is provided in

Appendix A.

2 PROPOSED DEVELOPMENT

2.1 Site Description

The proposed additions and alterations consist of adding additional outdoor dining (bistro), expanded beer

garden, outdoor children’s play area, two indoor adaptable function rooms, video arcade, along with internal

changes/relocation to the public bar, TAB and gaming areas.

The purpose of the proposed development is to upgrade the existing facilities associated with the Sportsmans

Hotel to increase the appeal and amenity to the local community. Figure 2-1 shows an aerial image of the

location of the hotel, the surrounding environment and the noise monitoring location.

2.2 Hotel Capacity

Iris Capital have proposed the following patron capacity levels for the venue.

Public Bar and TAB – 400 patrons

Bistro (internal) – 210 patrons

Bistro (external) – 200 patrons

Function Space – 130 patrons

Beer Garden – 170 patrons

Gaming Area – 60 patrons

Children’s Play Area – 30 patrons

It is proposed that external areas will not be used after midnight and the patron numbers from outside will be

moved inside and reduced to no more than 600 patrons internally.

3 BASELINE NOISE SURVEY

3.1 Unattended Noise Monitoring

In order to characterise the existing acoustical environment of the area unattended noise monitoring was

conducted between Tuesday 10th March and Monday 16th March 2020. Unattended noise monitoring was also

undertaken by RSA in 2018, the noise monitoring was conducted between Saturday 20th October and Monday

5th November 2018.

The first logger (2018) was located to the west of the site at the nearest residential receiver. The second logger

(2020) was located to the eastern edge of the site at the boundary of the carpark.

Logger locations were selected with consideration to other noise sources which may influence readings,

security issues for noise monitoring equipment and gaining permission for access from residents and

landowners.

Instrumentation for the survey comprised of 2 Octave Frequency Analyzing Environmental Noise Loggers

(serial numbers 8780FB and 572558) fitted with microphone windshield. Calibration of the logger was checked

prior to and following measurements. Drift in calibration did not exceed ±0.5 dB(A). All equipment carried

appropriate and current NATA (or manufacturer) calibration certificates.

Measured data has been filtered to remove data measured during adverse weather conditions upon

consultation with historical weather reports provided by the Bureau of Meteorology (BOM).

The logger determines LA1, LA10, LA90 and LAeq levels of the ambient noise. LA1, LA10, LA90 are the levels

exceeded for 1%, 10% and 90% of the sample time respectively (see Glossary for definitions in Appendix A).



Iris Capital

Detailed results at the monitoring location are presented in graphical format in Appendix B. The graphs show

measured values of LA1, LA10, LA90 and LAeq for each 15-minute monitoring period.

3.2 Data Processing

In order to establish the ambient noise criteria of the area, the data obtained from the noise logger has been

processed in accordance with the procedures contained in the NSW Environmental Protection Authority’s

(EPA) Noise Policy for Industry (NPfI, 2017) to establish representative noise levels that can be expected in

the residential vicinity of the site.

The monitored baseline noise levels are detailed in Table 3-1.

the same amount of acoustic energy as the corresponding time-varying sound.

LA90 Noise level present for 90% of time (background level). The average minimum background sound level (in the absence of the

source under consideration).

3.2.1 LG Analysis

Liquor and Gaming NSW provides a guideline to assess noise from licensed venues, the noise criteria is

required to be in one octave band frequency. The noise logger used for the unattended measurements has

the capability of recording noise data in one octave band frequency allowing us to establish spectral information

of typical background noise levels experienced by the nearby residential receivers.

The background noise levels have been processed in accordance with NPfI procedures and are presented in

octave band frequency form in Section 4.3 of this report.



Iris Capital

4 NOISE CRITERIA

The establishment of the noise criteria for the assessment of the proposed additions and alterations to the

existing hotel have been based on the LG noise guidelines.

4.1 Liquor and Gaming

LG guidelines for the assessment of noise from licensed premises is as follows:

a) The LA10 noise level emitted from the use must not exceed the background noise level (L90) in

any Octave Band Centre Frequency (31.5 Hz to 8 kHz inclusive) by more than 5 dB between

the hour of 7.00 am and 12.00 midnight when assessed at the boundary of any affected

residence.

b) The LA10 noise level emitted from the use must not exceed the background noise level (L90) in

any Octave Band Centre Frequency (31.5 Hz to 8 kHz inclusive) between the hour of

12.00 midnight and 7.00 am when assessed at the boundary of any affected residence.

c) Notwithstanding compliance with a) and b) above, the noise from the use must not be audible

within any habitable room in any residential property between the hours of 12.00 midnight and

7.00 am.

4.2 Operational Noise Criteria

Responsibility for the control of noise emissions in New South Wales is vested in Local Government and the

EPA. The EPA oversees the Noise Policy for Industry (NPfI) October 2017 which provides a framework and

process for deriving noise criteria. The nearest and most affected receivers to the south have been identified

as commercial premises. The NPfI criteria is therefore 65 dB(A) for commercial tenancies.

Any new items of mechanical plant must meet the following criteria:

4.3 Project Specific Noise Criteria

Based on the spectral data from the noise logger the project specific noise criteria for the operation of the

proposed additions and alterations to the hotel have been established in accordance with LG noise guidelines.

The project specific noise criteria for the residential receivers is presented in tables below.

5 NOISE IMPACT ASSESSMENT

5.1 Typical Patron Vocal Levels

The following sections summarise the results of patron and music noise assessment and predicted levels at

nearby receivers as a result of the operation of the proposed additions and alterations (see Figure 2-1 and

Figure 2-2).

Calculations of the amount of noise transmitted to these receivers from the proposed additions and alterations

have been based on voice levels as referenced in the Handbook of Acoustical Measurements and Noise

Control by Cyril M. Harris. This handbook provides voice spectrums for males and females as well as different

vocal efforts. The spectrum is given in Table 5-1.

The spectra have been scaled based upon the overall number of patrons expected to be in the respective

areas at any given time

Table 5-1 Speech Spectrums - Handbook of Acoustical Measurements and Noise Control.

Type

Noise Level (dB) at Octave Band Centre Frequency (Hz)

125 250 500 1 k 2 k 4 k 8 k

Male (Raised) 56 60 64 59 55 51 45

5.2 Patron Sound Power Levels

Based on the maximum number of patrons in all area as shown in Section 2.2, the following worst-case

operational scenarios have been assumed for our assessment:

Only 50% of all patrons per area will be talking at any given time, this is assuming that 1 person will be

talking and 1 person will be listening.

Table 5-2 Sound Power Levels of People talking with Raised Voice - Lw – dB(A)

Scenario

Resultant Sound Power Level per Octave Band (dB)

63Hz 125Hz 250Hz 500Hz 1kHz 2kHz 4kHz 8kHz

400 Patrons with Raised Vocal in the Public Bar and TAB

33 89 93 97 92 88 84 78

170 Patrons with Raised Vocal in the Beer Garden

29 85 89 93 88 84 80 74

30 86 90 94 89 85 81 75

200 Patrons with Raised Vocal in the Bistro (external)

30 86 90 94 89 85 81 75

130 Patrons with Raised Vocal in the Function Areas

22 78 82 86 81 77 73 67

10 Children with Raised Vocal in the Video Arcade

17 73 77 81 76 72 68 62

It is generally agreed that the human voice is not capable of producing noise at 32 Hz and 63Hz octave bands

at significant amplitudes. It is also very likely that even if noise emission in this low frequency octave bands

exceeds the noise criterion; it will be very close to, if not below, the human threshold of hearing at the receivers.

Appropriate sound power levels conversations have been made for the varying distribution number of patrons.



Iris Capital

5.3 Music Sound Power Level

RSA has conducted measurements of background music noise levels at various licensed venues, based on

these measurements the sound power level spectrum of typical music is shown in Table 5-3 below:

Table 5-3 Typical Sound Power Level of Typical Music - Lw – dB(A)

Scenario

Typical Live Band 93 103 103 102 104 97 91 90 87

5.4 Gaming Machine Noise Levels

The gaming area will comprise 30 gaming machines, with a capacity of 60 people, we have assumed that

patrons using the gaming area will not generate significant noise as they will be using the gaming machines.

We have also assumed that very low background music will be played in this area.

Spectra for average maximum noise levels (LA10) and energy-average noise levels (LAeq) have been measured

at a similar facility and are given below in Table 5-4. The measured spectra have been scaled based upon

the number of machines operating in the gaming area.

Table 5-4 Measured Gaming Machine Noise Levels

Calculations have been made based on the spectra above, scaled to reflect the 30 gaming machines being

used at the same time (worst case scenario) to determine the likely noise levels at nearby receivers

5.5 Predicted Hotel Noise Impacts

Predictive resultant noise spectrums have been calculated for all proposed hotel activities. Noise emissions at

the nearest receivers are presented in the tables below. The predicted noise calculations take into account

the following:

Heights of receivers are assumed to be 1.5 m above their respective floor level;

Live bands and DJs will be used in the public bar on Friday and Saturday nights (with external doors

closed);

Steel louvres are installed in the openings near the roof on the eastern and southern facades of the gaming

area;

A maximum of 30 poker machines will operate in the gaming area;



Iris Capital

The entry doors close automatically – except for the public bar leading to the beer garden – these doors

are assumed closed when the venue is at or near capacity;

The carpark capacity has not increased;

Any new mechanical plant items will be installed in the dedicated plant room (except where necessary to

be located elsewhere i.e. roof mounted);

The external areas will operate at or near capacity until midnight;

The internal areas will have a capacity of 600 people after midnight;

The existing noise barriers on the boundaries of the site have been taken into account;

A 2.1 metre tall solid barrier is assumed on the boundary between the beer garden/bistro and the existing

carpark.

Resulting noise levels have been calculated to the most affected point on the boundary of the affected receivers

The following figure shows the proposed development in relation to the most affected receivers.

6 RECOMMENDATIONS

The noise emissions from the proposed additions and alterations to the hotel have the potential to comply with

the required criteria with the implementation of the following recommendations:

6.1 Building Requirements

Proposed 2.1 metre barrier must be completely solid and free of gaps towards the east of the site, patron

entrance can only be to the north and south of the carpark. Barrier must be constructed out of masonry,

Slimwall or suitable equivalent material. Entrance door to be fully sealed and utilise air locks.

All external windows and doors facing north and east to have a minimum Rw 36 rating on aluminium

windows and acoustically sealed frame. Suitable window glazing thickness would be 10.38mm laminated

glass on acoustically sealed aluminium frame

Bifold doors facing east to have minimum Rw 36 rating and acoustic rated seals.

All external windows and doors facing south to have Rw 34 rating.

Acoustic absorption must be incorporated into the design of the roof of the outdoor area. Absorption must

cover a minimum 80% of the surface area of the ceiling, with an NRC rating of 0.8 and consist of absorptive

panels on the ceiling surface itself. Absorption must be at least 50mm thick. Precise design and selection

of materials must be approved by a qualified Acoustic Consultant at Construction Certificate stage.

6.2 Operational

Bifold doors to public bar to be closed when the capacity of the public bar is more than 200 people;

External doors to public bar to be closed during any live music/DJ performances. Live music and DJ

speakers are to utilise in house PA system;

PA system to have a noise limiter with a maximum SPL 90 dB(A) at 1m from the speaker. All speakers are

to face internal space;

External doors and windows to be closed at 10:00 pm;

Internal capacity after midnight no more than 600 patrons;

Outside areas to be closed and vacated before midnight;



Iris Capital

New items of mechanical plant which do not need to be roof mounted to be located within dedicated plant

room;

Patrons to be encouraged to leave in a quiet and orderly manner.

6.3 Mechanical Plant

It is recommended that any new items of mechanical plant be assessed by a qualified acoustic consultant

when detailed design and selection is known before Construction Certificate approval. It is likely that criteria

set out in Table 4-1 will be met through sensible selection of plant and location, and the implementation of

screening or enclosures if required for specific plant items.

7 CONCLUSION

A noise impact assessment has been conducted in relation to the operation of the proposed additions and

alterations at the existing hotel located at 81 Kildare Road, Blacktown NSW 2148.

This assessment has been conducted and appropriate noise emission criteria have been established in

accordance with Liquor & Gaming NSW noise guidelines and EPA’s Noise Policy for Industry criteria.

This report shows compliance with the specific noise criteria with the implementation of the recommendations

provided in this report. It is therefore recommended that planning approval be granted for the proposed

additions and alterations on the basis of acoustics.

Appendix A – Acoustic Terminology

A-weighted sound

pressure

The human ear is not equally sensitive to sound at different frequencies.

People are more sensitive to sound in the range of 1 to 4 kHz (1000 –

4000 vibrations per second) and less sensitive to lower and higher

frequency sound. During noise measurement an electronic ‘A-weighting’

frequency filter is applied to the measured sound level dB(A) to account

for these sensitivities. Other frequency weightings (B, C and D) are less

commonly used. Sound measured without a filter is denoted as linear

weighted dB(linear).

Ambient noise The total noise in a given situation, inclusive of all noise source

contributions in the near and far field.

Community

annoyance

Includes noise annoyance due to:

character of the noise (e.g. sound pressure level, tonality,

impulsiveness, low-frequency content)

character of the environment (e.g. very quiet suburban, suburban,

urban, near industry)

miscellaneous circumstances (e.g. noise avoidance possibilities,

cognitive noise, unpleasant associations)

human activity being interrupted (e.g. sleep, communicating, reading,

working, listening to radio/TV, recreation).

Compliance The process of checking that source noise levels meet with the noise

limits in a statutory context.

Cumulative noise

level

The total level of noise from all sources.

Extraneous noise Noise resulting from activities that are not typical to the area. Atypical

activities may include construction, and traffic generated by holiday

periods and by special events such as concerts or sporting events.

Normal daily traffic is not considered to be extraneous.

Feasible and

reasonable

measures

Feasibility relates to engineering considerations and what is practical to

build; reasonableness relates to the application of judgement in arriving

at a decision, taking into account the following factors:

Noise mitigation benefits (amount of noise reduction provided,

number of people protected).

Cost of mitigation (cost of mitigation versus benefit provided).

Community views (aesthetic impacts and community wishes).

Noise levels for affected land uses (existing and future levels, and

changes in noise levels).

Impulsiveness Impulsive noise is noise with a high peak of short duration or a sequence

of these peaks. Impulsive noise is also considered annoying.

Low frequency Noise containing major components in the low-frequency range (20 to

250 Hz) of the frequency spectrum.

Noise criteria The general set of non-mandatory noise levels for protecting against

intrusive noise (for example, background noise plus 5 dB) and loss of

amenity (e.g. noise levels for various land use).

Noise level (goal) A noise level that should be adopted for planning purposes as the

highest acceptable noise level for the specific area, land use and time of

day.

Noise limits Enforceable noise levels that appear in conditions on consents and

licences. The noise limits are based on achievable noise levels, which

the proponent has predicted can be met during the environmental

assessment. Exceedance of the noise limits can result in the requirement

for either the development of noise management plans or legal action.

Performance-

based goals

Goals specified in terms of the outcomes/performance to be achieved,

but not in terms of the means of achieving them.

Rating

Background Level

(RBL)

The rating background level is the overall single figure background level

representing each day, evening and night time period. The rating

background level is the 10th percentile min LA90 noise level measured

over all day, evening and night time monitoring periods.

Receptor The noise-sensitive land use at which noise from a development can be

heard.

Sleep disturbance Awakenings and disturbance of sleep stages.

Sound and

decibels (dB)

Sound (or noise) is caused by minute changes in atmospheric pressure

that are detected by the human ear. The ratio between the quietest noise

audible and that which should cause permanent hearing damage is a

million times the change in sound pressure. To simplify this range the

sound pressures are logarithmically converted to decibels from a

reference level of 2 x 10-5 Pa.

The picture below indicates typical noise levels from common noise

sources.

dB is the abbreviation for decibel – a unit of sound measurement. It is

equivalent to 10 times the logarithm (to base 10) of the ratio of a given

sound pressure to a reference pressure.

Sound power

Level (SWL)

The sound power level of a noise source is the sound energy emitted by

the source. Notated as SWL, sound power levels are typically presented

in dB(A).

Sound Pressure

Level (SPL)

The level of noise, usually expressed as SPL in dB(A), as measured by a

standard sound level meter with a pressure microphone. The sound

pressure level in dB(A) gives a close indication of the subjective loudness

of the noise.

Statistic noise

levels

Noise levels varying over time (e.g. community noise, traffic noise,

construction noise) are described in terms of the statistical exceedance

level.

A hypothetical example of A weighted noise levels over a 15 minute

measurement period is indicated in the following figure:

Key descriptors:

LAmax Maximum recorded noise level.

LA1 The noise level exceeded for 1% of the 15 minute interval.

LA10 Noise level present for 10% of the 15 minute interval. Commonly

referred to the average maximum noise level.

LAeq Equivalent continuous (energy average) A-weighted sound

pressure level. It is defined as the steady sound level that contains the

same amount of acoustic energy as the corresponding time-varying

sound.

LA90 Noise level exceeded for 90% of time (background level). The

average minimum background sound level (in the absence of the source

under consideration).

Threshold The lowest sound pressure level that produces a detectable response (in

an instrument/person).

Tonality Tonal noise contains one or more prominent tones (and characterised by

a distinct frequency components) and is considered more annoying. A 2

to 5 dB(A) penalty is typically applied to noise sources with tonal

characteristics
