Document Ref. 020207-RPT-AS-00

Executive Summary

This report provides acoustic advice relating to the town planning application for the proposed development project

situated at 60-88 Langridge Street & 23-45 Waterloo Road, Collingwood.

Cundall has completed a noise survey at the neighbouring development site, which is considered to be representative of

prevailing conditions affecting the proposed site.

Based upon survey data, noise limits determined in accordance with State Environment Protection Policy No. N-1

(SEPP N-1) and State Environment Protection Policy No. N-2 (SEPP N-2) have been established. These noise limits

should be used when assessing noise from building services and music noise, respectively.

Preliminary recommendations for façade glazing to control external noise intrusion have been developed based upon

measurements of traffic noise on Langridge Street. Noise to the development is predicted to be adequately controlled

using standard glazing elements.

1.0 Introduction


Document Ref. 020207-RPT-AS-00 1

1.0 Introduction

Cundall has been engaged by Peregrine Projects to assess potential noise impacts relating to the proposed

development at 23-45 Waterloo Road & 88 Langridge Street (the Proposal). The proposal seeks to construct two multi-

level buildings: both will provide office facilities, however one of the buildings will also incorporate three retail units at

ground floor. These tenancies are to be two restaurants and a fitness centre.

This report summarises survey data relating to the existing ambient noise environment at the site, comments on relevant

acoustic design criteria, and considers appropriate design strategies to achieve an acceptable acoustic amenity to be

provided.

1.1 Site description

Figure 1 highlights the proposed development site and the immediate surrounds. The site is currently occupied by two

buildings and a parking lot. The surrounding area comprises predominantly retail shops and business buildings, however

there is residential development approximately 13 metres from the site boundary (highlighted below). The potential noise

impact of the proposed development on these residential receivers will need to be considered, in addition to

environmental noise intrusion to the development itself.

1.2 Proposed development

The proposed western building will comprise seven floors of office accommodation at upper levels with a mix of

commercial and retail tenancies at ground floor. Both will share a two-level basement carpark. Figure 2 indicates the

proposed ground floor layout and Figure 3 illustrates the shared carpark.

2.0 Existing noise environment



2.0 Existing noise environment

Cundall completed a Town Planning Report in relation to the Tribe Collingwood development at 60-68 Langridge Street,

Collingwood plot in August 2018. The assessment of the proposed development at 60-88 Langridge Street & 23-45

Waterloo Road, Collingwood (project site) will be based on the environmental noise data obtained for this adjacent

project.

Acoustic terminology used in this report is summarised in Appendix A.

2.1 Nearby noise sources

The prevailing noise climate around the site has been noted to be typical of an urban setting, comprising predominantly

road traffic noise and general mechanical plant noise. Road traffic on Langridge Street is considered to be the dominant

noise source affecting the proposed development site.

2.2 Unattended noise survey

The following tables summarise measurements made during the unattended noise survey at the adjacent site. The

measurement position is considered representative of the most affected façades at the project site, and also considered

acceptable for determining the ambient noise conditions, as Langridge Street is relatively quiet during the night-time

period.

Figure 4 presents the time history of noise levels at the monitoring location over the course of the survey. Data from

14-18 June will be excluded from the analysis below, due to adverse impact from rain.

Figure 4 Measured noise level time history (14 June – 22 June 2018)

Table 2 below indicates the background noise levels obtained.



Table 3 presents the average measured road traffic noise at the most exposed façade location during peak noise

periods during both the day and night.

3.0 Acoustic design criteria



3.0 Acoustic design criteria

3.1 Environmental noise emissions

Noise from commerce and industry in the State of Victoria is required to comply with State Environmental Protection

Policy No. N-1 (SEPP N-1). This compliance is a mandatory requirement under Section 46 of the Environment

Protection Act 1970.

The SEPP N-1 noise limits are separated into day, evening and night periods, and determined by comparing the

planning scheme of the area surrounding the site to measurements of the existing ambient noise environment during

these three time periods.

Appendix B shows the planning map of the proposed development site and surrounds.

The determined day, evening and night period SEPP N-1 noise limits are detailed in Table 4.

Time period Zoning level Measured background

noise level, dB LA90

Noise limit, dB LAeq

Daytime 50 54 60

Evening 44 48 51

Night-time 39 42 45

All commercial noise from the development is required to comply with these noise limits at the nearest affected

residences.

3.2 Deliveries to site

EPA (Vic) Publication No.1254, Noise Control Guidelines states the following concerning store deliveries:

Where a residential area will be impacted by noise from deliveries, the deliveries should be inaudible in a

habitable room of any residential premises (regardless of whether any door or window giving access to the room

is open) outside the hours contained in the schedule

Schedule: Deliveries to shops, supermarkets & service stations

• 7am-10pm Monday to Saturday

• 9am-10pm Sunday and Public Holidays

Note: All ancillary motors or trucks should be turned off whilst making the delivery.

The relevant sections of the Publication are provided in Appendix C for reference.

3.3 Waste collection from site

EPA (Vic) Publication No.1254, Noise Control Guidelines provides the following recommendations for industrial waste

collections:

Early-morning collections should be restricted to non-residential areas to minimise early morning disturbances.

Where a residential area is impacted by noise from the collection of refuse, then collections should be restricted to

the times contained within the schedule.

• Refuse bins should be located at sites that provide minimal annoyance to residential premises



• Compaction should be carried out while the vehicle is moving

• Bottles should not be broken up at the collection site

• Routes which service predominantly residential areas should be altered regularly to reduce early

morning disturbances

• Noisy verbal communication between operators should be avoided where possible.

The Guidelines recommend that collections should be restricted to the following times:

Schedule: industrial waste collection

One collection per week –

• 6:30am-8pm Monday to Saturday

• 9am-8pm Sunday and Public Holidays

Two or more collections per week –

• 7am-8pm Monday to Saturday

• 9am-8pm Sunday and Public Holidays.


3.4 Music noise from site

We understand that music may be played within the ground floor tenancies.

EPA (Vic) Publication No.1254, Noise Control Guidelines provides the following recommendations regarding noise from

shops:

Where amplified speech or music from shops (spruiking) is to be controlled, the following conditions may be

specified.

Each loudspeaker or loudspeaker system to be placed in such a position that, while it is in use, it remains:

• located entirely inside the shop

• situated not less than three metres from any public entrance to the shop

• directed in such a manner that the device does not point towards any wall which contains an external

window or entrance to the shop unless the wall is more than 15 metres from the device itself

• operating at a level that does not exceed 65 dB(LAeq) two metres from the facade.


Music from entertainment venues should also be assessed in accordance with State Environment Protection Policy No.

N-2 (SEPP N-2), which defines mandatory noise limits for music associated with public premises in the State of Victoria,

including indoor and outdoor venues.

Noise limits are based upon an adjustment to the background noise levels in the absence of music.

The noise limits for indoor venues are established based on the measured noise level in accordance with SEPP N-2 as

follows:

• Daytime (0700-1800hrs) and Evening (1800-2200) periods: LAeq = LA90 + 5 dB1,

• Night-time period (2200-0700hrs): LOCT10 (63 Hz to 4kHz) = LOCT90 (63 Hz to 4kHz) + 8 dB2.

1 Note: Except operations that occur no more than 10 events per year. In which case, further allowance of 3 dB can be added to the daytime and

evening period limits. 2 Note: Octave band frequency between 63 Hz - 4 kHz inclusive.



Noise limits are applicable at the nearest noise sensitive receivers.

Analysis of the survey data at the nominated monitoring location is presented in Table 5 (Daytime and evening) and

(night-time) alongside the derived SEPP N-2 limiting noise level.

These limits should be applied to the cumulative level of music and entertainment noise associated with the three ground

floor tenancies, when assessed at the nearest residential receivers. It is understood that there will be no live music from

the proposed tenancies as such, the practice note (Planning Practice Note 81, Clause 52.43 – Live Music and

Entertainment Noise) does not apply.

3.5 Noise from patrons of the roof top terrace

3.5.1 Guidelines for patron noise assessment

There is no legislative requirement or guidance for the assessment and control of noise from patrons at an entertainment

venue, save for when that noise is directly associated with music from the venue (i.e. a karaoke bar).

The Association of Australian Acoustic Consultants (AAAC) has not reached a consensus on the most appropriate way

to assess this form of noise, though draft guidelines exist.

A paper3 presented to the Australian Acoustic Society (AAS) by M.J.Hayne et. al. provides guidance for the prediction of

noise from such groups of people based upon experimental evidence and theory and is currently the accepted method

of predicting noise from patrons by the AAAC.

As a means of assessment, a common practice for acoustic consultants is to compare these predicted patron noise

levels to the existing ambient noise levels to determine the likelihood of adverse impact on nearby residences. In their

evidence for the proposed development at 820 Plenty Road, South Morang4, Marshall Day Acoustics (MDA) provides

the guidance for the development of patron noise design targets, as detailed in Table 7.

3 Hayne et al 2011, ‘Prediction of noise from small to medium sized crowds’, in Acoustics 2011: Breaking New Ground, Proceedings of the Annual

Conference of the Australian Acoustical Society, AAS Queensland Division 2011, Gold Coast, paper number 133.

We propose to use these design targets for guidance purposes only and should not be considered strict criteria. Table 8

provides the MDA commentary on the relative difference between the design targets and the predicted or measured

patron noise levels.

Predicted noise level Likely impact

Meets the proposed criteria No impact likely

Exceeds the proposed criteria by up to 2 dB No impact likely

Exceeds the criteria by 3-5 dB There is a possibility of impact and the proposal should be assessed with

measurements once it is operational to determine typical crowd noise levels from

the venue. Provision should be made to adopt managerial controls and retrofit

engineering controls if deemed necessary.

Exceeds the criteria by 5-8 dB There is a strong possibility of impact and engineering controls should be

incorporated. Managerial controls should also be considered at the planning stage.

Further measurements will be required once the development is operational to

determine appropriate managerial controls.

Exceeds the criteria by more than 8 dB There will be noise impact and major changes to the design and/or operation of the

proposed outdoor area will be required

3.6 Sleep disturbance

The NSW Road Noise Policy 2011 produced by the NSW EPA, provides guidance on potential for sleep disturbance.

While the Policy applies strictly only in NSW, the provisions of the document are often referred to in Victoria for general

guidance on potential sleep disturbance.

The NSW policy notes that from the research on sleep disturbance to date it can be concluded that:

▪ Maximum internal noise levels below 50–55 dB LAmax are unlikely to awaken people from sleep

▪ One or two noise events per night, with maximum internal noise levels of 65–70 dB LAmax, are not likely to affect

health and wellbeing significantly.

Based upon the above and an approximate reduction of 10 dB through an open window, a noise level of 65 dB LAmax

outside an open window is unlikely to result in awakening reactions.

3.7 External noise intrusion

Australian Standard AS2107:2016 Acoustics – Recommended design sound levels and reverberation times for building

interiors (AS2107) provides guidance for acceptable noise levels within commercial buildings. Relevant design criteria

are reproduced in Table 9 below.



Table 9 - AS2107 Recommended internal noise levels

Type of occupancy Design sound level range (dB LAeq)

Restaurants 40 – 50

Coffee shops 40 – 50

Kitchen < 55

Indoor sports- w/ coaching < 45

General office areas 40 – 45

Corridors and lobbies 45 – 50

Video/audio conference rooms 30 – 40

Toilets 45 – 55

Undercover carparks < 65

Toilets/change/shower < 55

Small retail stores (general) < 50

Utility rooms 50 – 60



4.0 Acoustic design and recommendations



4.0 Acoustic design and recommendations

4.1 Road traffic noise intrusion

Based upon the measured traffic noise levels on Langridge Street the noise level incident on the most exposed facades

of the development (i.e. the two restaurants and ground floor level and office spaces on upper floors that have a direct

line of sight to Langridge Street) are predicted to be up to 67 dB LAeq,1hr.

The northern façade (Waterloo Road) traffic noise levels are predicted to be 3-6 dB lower than those on Langridge Street

due to their lower traffic exposure. A 3 dB reduction has been assumed to be conservative.

From the recommended internal noise level criteria set out on page 10, it can be seen that the most onerous

requirement within the development (excluding video/audio conference rooms) is 40-45 dB LAeq.

Based on the predicted façade noise levels, the following glazing attenuation values would be required:

• Facades with a line-of sight to Langridge Street: 27-22 dB Rw;

• Waterloo Road façade: 24-19 dB Rw.

This level of acoustic performance can be easily achieved by typical single or double-glazed units.

The acoustic performance of glazing systems should not be compromised by the framing system or seals. It is

recommended that any selected systems be reviewed by a suitably qualified acoustic consultant.

4.2 Mechanical plant noise emissions

At this stage, the specific location of building services plant has not been defined, however this is expected to be on the

roof level of each building. The exact plant selection is expected to take place during detailed design stage of the project.

It is predicted that noise from mechanical plant associated with the development can be adequately controlled such that

the requirements of SEPP N-1 as set out in Section 3.1 above can be achieved at nearby noise sensitive receivers.

Mechanical plant noise can typically be controlled through common engineering methods such as selection of lower

noise plant, placement location of plant, physical barriers, silencers and acoustically lined ductwork.

The selection of plant and design of plant compounds should be reviewed and assessed for conformance with

nominated noise levels at the detailed design stage of the project once specific plant selection is finalised.

4.3 Music noise

We have not conducted an assessment of music noise, as the operator of each tenancy has not been finalised at this

stage. Music noise impact must comply with the determined SEPP N-2 music noise limits detailed in Section 3.4.

We recommend that any future tenant be informed that, as part of their tenancy agreement, they must ensure that any

music is played at a level which will comply with the determined SEPP N-2 music noise limits above at the nearest

affected residential dwellings.

Our preliminary guidance on music noise is as follows:

▪ Any music should be played at a level which may be considered "background"

▪ All music must be played though the tenancies in-house AV equipment

▪ Amplification should be provided with some form of noise limiting or threshold warning device

▪ No amplified live music should be performed at the venue.

An assessment of music noise from the proposed restaurant tenancies to the nearest sensitive receivers should be

completed during the design of those tenancies.



4.4 Noise from patrons

Noise from patron (outdoor seating areas) have potential to impact the acoustic amenity of the surrounding receivers.

Based on the area allocation for outdoor seating, the outdoor areas are expected to accommodate up to 19 and 10

patrons for the 38 m2 and 19 m2 respectively. The nearest sensitive receivers identified for each of the outdoor areas are

presented in Table 10.

Based on the estimated outdoor patron numbers (one seating patron per 2 m2), with 50 percent of the patrons engaged

in conversation in raised vocal effort, the predicted resultant noise level at the nearest sensitive receivers are presented

in Table 11.

Tenancy 2 19 21 Waterloo Road 48 Yes Yes Yes

22 Waterloo Road 48 Yes Yes Yes

Tenancy 3 10 79 Rokeby Street 52 Yes Yes Yes

The predictions indicate that patron noise is likely to comply with the design levels during the daytime and evening and

night-time for both tenancies. It is recommended that the assumptions used in our predictions should be reviewed once

final patron numbers are confirmed.

The predicted maximum noise level events from patrons within the outdoor seating areas are up to 61 dB LAmax and

65 dB LAmax from Tenancy 2 and Tenancy 3 respectively. These noise levels are below / at the guided maximum external

noise level compliance for sleep disturbance (Section 3.6) of 65 dB LAmax. As such, sleep disturbance events due to

patron noise within the outdoor area use are considered unlikely.

Furthermore, it is understood that the adjacent project, Tribe Hotel, has also been proposed during the assessment of

this project. Based on our understanding of the Tribe Hotel project, the proposed eastern (most affected façade) where

the highest impacts from outdoor dining of the proposed Tenancy 2 and Tenancy 3 may be expected, does not contain

glazed elements. It is therefore unlikely that the outdoor seating areas of both tenancies will significantly impact Tribe

Hotel project residents significantly. However, compliance of the outdoor seating areas Tenancy 2 and Tenancy 3 to

Tribe Hotel project is subject to planning approval process and design of the Hotel. It is recommended that the

assumptions used in our predictions should be reviewed should the Tribe Hotel project is approved prior and if

information is available for assessment.



Notwithstanding the above, consideration of patron management should be included with in the Noise and Amenity

Action Plan. This include but not limited to:

▪ Staff training

▪ Restriction of patron numbers within the outdoor areas

▪ Signage should be provided indicating that patrons are in a residential area, and congregation at this location should

be discouraged

▪ Queuing management

4.5 Noise and vibration impact from Fitness Centre tenancy

As part of management practice, consideration to patron entering / leaving the Fitness Centre in the early morning hours

or night-time should be controlled as far as practicable. This includes but not limited to:

▪ Patron briefing to inform them of the noise sensitivity of the area;

▪ ensuring that the entry door is shut when not in use;

▪ restriction on the use of amplified music within the tenancy only to serve as background music between 5:30 am

and 7:00 am

In addition to noise from the Fitness Centre operation to the adjacent residential receivers, there is a potential for noise

(structure-borne) and vibration impacts to the offices located within the building above the Fitness Centre. This may

cause by weight dropping and amplified music. We recommend that, as part of their tenancy agreement, future tenant be

informed regarding:

▪ equipment which could potentially cause impacts to the structure be sufficiently isolated by means of physical

isolation (i.e. rubber mats, to be confirmed by suitability qualified structural engineer); and

▪ implementation of management practice such as signage and induction for members regarding Fitness Centre

usage etiquette.

4.6 Site management for licensed premises (Yarra Planning Scheme Clause 22.09 Licensed

Premises)

As part of the requirement for the proposed licensed premises, a Noise and Amenity Action Plan (NAAP) should be

prepared. The NAAP should include but not limited to the following items:

▪ Procedures to be undertaken by staff in the event of complaints by a member of the public, the Victoria Police, an

‘authorised officer’ of Council or the Victorian Commission for Gambling and Liquor Regulation.

▪ The management and dispersal of patrons, including patrons loitering around the venue after the venue has closed.

▪ The management of large group bookings.

▪ The management of smokers and on and off-site smoking areas (particularly where liquor may not be allowed to be

sold and consumed within the smoking area after a particular time).

▪ The management of external queues.

▪ How the movement and exit of patrons is to be managed, particularly where there is a requirement to close different

sections of the venue at different times.

▪ Details of the provision of music including the frequency and hours of entertainment (e.g. by live bands and DJs if

any).

▪ Any other measures to be undertaken to ensure no unreasonable amenity impacts from the licensed premises.



5.0 Conclusion



5.0 Conclusion

Peregrine Projects is proposing to develop two new multi-level buildings on the site of 60-88 Langridge Street & 23-45

Waterloo Road, Collingwood. The development will provide a number of office floors, in conjunction with three

commercial tenancies at ground floor level of the eastern building.

Based upon representative environmental noise survey data, appropriate acoustic design criteria have been set out, in

accordance with SEPP N-1 (commercial and industrial noise) and SEPP N-2 (control of music noise from public

premises). In addition, reference is made to the EPA (Vic) Publication No.1254 in relation to deliveries and waste

collection and music noise from shops.

Reference to Australian Standard AS2107:2016 has been made, to determine appropriate internal design sound levels

due to environmental noise intrusion. An assessment of road traffic noise impact at the site has been made, to enable

preliminary recommendations for façade glazing performance to be determined.

It is concluded that potential noise impacts should not preclude the proposed development on the assessment site.



6.0 Appendix



Appendix A Acoustic Terminology

‘A’-WEIGHTED SOUND LEVEL dBA

The unit generally used for measuring environmental, traffic or industrial noise is the A-weighted sound pressure level in

decibels, denoted dBA. An A-weighting network can be built into a sound level measuring instrument such that sound

levels in dBA can be read directly from a meter. The weighting is based on the frequency response of the human ear

and has been found to correlate well with human subjective reactions to various sounds. An increase or decrease of

approximately 10 dB corresponds to a subjective doubling or halving of the loudness of a noise. A change of 2 to 3 dB is

subjectively barely perceptible.

EQUIVALENT CONTINUOUS SOUND LEVEL (LAeq)

Another index for assessment for overall noise exposure is the equivalent continuous sound level, Leq. This is a notional

steady level, which would, over a given period of time, deliver the same sound energy as the actual time-varying sound

over the same period. Hence fluctuating levels can be described in terms of a single figure level.

FREQUENCY

The rate of repetition of a sound wave. The subjective equivalent in music is pitch. The unit of frequency is the Hertz

(Hz), which is identical to cycles per second. A thousand hertz is often denoted kilohertz (kHz), e.g. 2 kHz = 2000 Hz.

Human hearing ranges from approximately 20 Hz to 20 kHz. The most commonly used frequency bands are octave

bands, in which the mid frequency of each band is twice that of the band below it. For design purposes, the octave

bands between 63 Hz to 8 kHz are generally used. For more detailed analysis, each octave band may be split into three

one-third octave bands or, in some cases, narrow frequency bands.

LA90

Refers to the sound pressure level measured in dBA, exceeded for 90% of the measured time period i.e. measured

noise levels were greater than this value for 90% of the time interval. This is also often referred to the background noise

level, or ambient noise level.

LA10

Refers to the sound pressure level measured in dBA, exceeded for 10% of the measured time period. This is often

referred to as the average maximum noise level and is frequently used to describe traffic noise.
