Part 5.3 of the Regulations covers noise. Division 1 requires the prediction, measurement, assessment or analysis of noise within a noise sensitive area to be conducted in accordance with the Noise Protocol.

Part 5.3, Division 3 of the Regulations applies to noise from commercial, industrial and trade premises. It provides that noise is prescribed unreasonable noise if the following circumstances all apply:

  • it is emitted from commercial, industrial and trade premises
  • it is emitted from sources other than those listed in regulation 117
  • the effective noise level exceeds:
    • the noise limit that applies at the time the noise is emitted (day, evening or night period) in a noise sensitive area (regulation 118(1)(a)), or 
    • the alternative assessment criterion that applies at the time the noise is emitted if the assessment of an effective noise level is conducted at an alternative assessment location in accordance with the Noise Protocol (regulation 118(1)(b))

It is important to note that, even when the above doesn't apply, noise can still be unreasonable under paragraph (a) of the definition of unreasonable noise having regard to the factors in that paragraph. Refer to unreasonable noise guidelines for detailed guidance on those factors. 

4.1. What are commercial, industrial and trade premises

Commercial, industrial and trade premises means any premises except:
  • a residential premises (other than common plant under the control of an owner’s corporation)
  • a street or road, including every carriageway, footpath, reservation and traffic island on any street or road
  • a railway track used by rolling stock in connection with freight or passenger services in certain circumstances
  • Luna Park in St Kilda.
The definition of commercial, industrial and trade premises is broad and does not rely on the premises being used for a business or other commercial activity. For example, it includes:
  • schools, public buildings, offices, and similar premises 
  • common plant under the control of an owner’s corporation at residential premises, including common air conditioning units, car stackers and lift equipment in apartment buildings.

4.1.1. Streets and roads

Part 5.3 of the Regulations does not apply to noise from road traffic or motor vehicles on highways. Noise from motor vehicles used on roads is regulated under Part 5.6 of the Regulations.

Part 5.3 of the Regulations applies to noise from commercial vehicles operating at commercial, industrial and trade premises and maintenance of any vehicles (including non-commercial vehicles) at these premises.

While Part 5.3 of the Regulations does not apply to road traffic or vehicles on roads, it does apply to operations of road infrastructure, such as tunnel ventilation systems. Activities related to the design, construction and maintenance of roads and road-related infrastructure are subject to the GED.
 
Part 6 of this guide provides links to practical guidance for people undertaking a design or civil construction activity about how they can implement controls to minimise risks associated with noise emissions.
 

4.1.2. Railway tracks

The definition of commercial, industrial and trade premises in the Regulations excludes railway tracks in the following circumstances: 

  1. a railway track used by rolling stock in connection with the provision of a freight service or passenger service
    1.  while travelling on a railway track or tramway track; or 
    2.  while entering or exiting a siding, yard, depot or workshop; 
  2. a railway track used by rolling stock in connection with the provision of a passenger service, while in a siding, yard, depot or workshop and is
    1. powering up to commence to be used in connection with the provision of a passenger service; or 
    2. shutting down after being used in connection with the provision of a passenger service.

Noise emissions from trains or trams used by a passenger transport company for the provision of a passenger service are excluded from the application of the Act and the Regulations under section 251B of the Transport (Compliance and Miscellaneous) Act 1983. 

While the Act and Part 5.3 of the Regulations do not apply to noise from railway tracks in the above circumstances, they do apply to the maintenance, cleaning or loading of rolling stock stabled in a siding, yard, depot or workshop.

The GED and unreasonable noise provisions determined by the factors in paragraph (a) of the definition of unreasonable noise also apply to the operation of rail and rail-related infrastructure, such as noise from transformers that service the rail. Refer to unreasonable noise guidelines for detailed guidance on unreasonable noise determined by factors under the Act.

4.2. Sources of noise that are not assessed under the Regulations 

 Noise sources that must not be considered when assessing noise from commercial, industrial and trade premises under Division 3 of Part 5.3 of the Regulations are listed in regulation 117. These are: 
  • music
  • voices
  • noise from:
    • crowds
    • firearms
    • lawnmowing
    • construction or demolition activities on building sites
    • sporting events
    • intruder, emergency or safety alarms or sirens
    • aircraft (except for ground maintenance activities)
    • mobile farm machinery (except for maintenance activities)
    • scare and anti-hail guns
    • livestock on farms or saleyards
    • equipment used in relation to an emergency
    • non-commercial vehicles (except for maintenance activities)
    • large fans used to circulate air over a wide area where crops such as citrus, stone fruit or vines are grown (frost fans)
    • wind turbines at wind energy facilities (used to generate electricity by wind force)
    • blasting undertaken in association with earth resources activity.
While these noise sources are excluded from a noise assessment under Division 3 of Part 5.3 of the Regulations they may be assessed under other parts of the Regulations. For example, music from entertainment venues is covered under Division 4 of Part 5.3 of the Regulations.

Noise emitted from a source that is listed in regulation 117 may still be unreasonable noise based on any factor or combination of factors listed in paragraphs (a)(i)–(v) of the definition of unreasonable noise in section 3(1) of the Act. For example:
  • Intruder, emergency and safety alarms and sirens – such as reversing alarms on forklifts, need to be clearly audible to ensure safe operation. However, the intensity of the alarm or horn noise must be proportionate to the location and safety requirements. To ensure that the noise from these alarms and sirens is not unreasonable noise, the factors in the definition of unreasonable noise must be considered. 
  • Noise from equipment used in an emergency – such as a hospital specialist ventilation system used during an emergency to prevent the spread of airborne infection – may be excluded from assessment by regulation 117 but may still be unreasonable under the definition of unreasonable noise in the Act. The Noise Protocol (Clause 37) sets out the noise limits that apply to the testing and maintenance of emergency equipment. Clause 38 sets out examples of emergency equipment.

Prescribed factors under section 3(1)(a)(v) (such as frequency spectrum under regulation 120) need only be considered if the noise source (including a source listed in regulation 117) is located at a commercial, industrial or trade premises.

4.2.1. Safety and emergency equipment 

Noise from equipment used in relation to an emergency are excluded by regulation 117 from a noise assessment under Division 3 of Part 5.3 of the Regulations. As is noise from intruder, emergency and safety alarms and sirens (which includes train horns used as a safety function). 

Although intruder, emergency and safety alarms and sirens, such as reversing alarms on forklifts, will need to be easily audible to ensure safe operation, the intensity of the alarm or horn noise will need to be proportionate to the location and safety requirements.  To ensure that the noise from intruder, emergency and safety alarms and sirens is not unreasonable noise, the factors in paragraphs (a)(i)–(iv) of the definition of unreasonable noise in section 3(1) the Act (such as time, place, circumstances, duration) must be considered. Prescribed factors under section 3(1)(a)(v) (such as frequency spectrum under regulation 120) need only be considered if the noise source (including a source listed in regulation 117) is located at a commercial, industrial or trade premises.

An emergency includes short-term emergencies such as a structure fire, and longer-term emergencies like a disease outbreak or epidemic. Noise from a hospital specialist ventilation system used in relation to an emergency to prevent the spread of airborne infection may be excluded by regulation 117 and therefore not assessed under Part 5.3 of the Regulations.  

Clause 37 of the Noise Protocol sets out the noise limits that apply to the testing and maintenance of emergency equipment. Clause 38 of the Noise Protocol sets out examples of the emergency equipment.

4.2.2. Irregular noise


Noise from activities that cause brief, high-noise emissions at night can disturb residents’ sleep and unreasonably affect communities. Examples are night-time vehicle movements, steam releases, loading, unloading, or impact activities. 
 
The effect of these types of noise is not well assessed by the Noise Protocol measurement method when they occur only a few times in a 30-minute period. The factors in paragraphs (a)(i)–(v) of the definition of unreasonable noise in the Act must be considered to ensure the noise emitted is not unreasonable noise. Prescribed factors under section 3(1)(a)(v) need only be considered if the noise source (including a source listed in regulation 117) is located at a commercial, industrial or trade premises.
 

4.3. Operating times

Regulation 116 sets operating time periods for commercial, industrial and trade premises to provide for generally lower noise limits at more sensitive times, such as at night when people usually sleep. The operating time periods are shown in Table 1.

Table 1: Operating time periods for commercial, industrial and trade premises
Period Time and days
Day 7 am to 6 pm Monday to Saturday (except public holidays)
Evening

6 pm to 10 pm Monday to Saturday

7 am to 10 pm Sunday and public holidays

Night 10 pm to 7 am the following day

4.4. Noise limits

In Part 5.3 of the Regulations (other than Division 5) noise limit means the maximum effective noise level allowed in a noise sensitive area, as determined in accordance with the Noise Protocol.

The Noise Protocol sets out how to conduct noise-related assessments, including the methods for setting noise limits and assessing the noise. 

EPA publication 1997 Technical guide: Measuring and analysing industry noise and music noise describes how to use the Regulations and Noise Protocol to predict, measure and assess noise from commercial, industrial and trade premises. 

To assess whether a commercial, industrial or trade premises complies with prescribed unreasonable noise requirements, the effective noise level at a noise sensitive area is compared with the noise limits set under the Regulations and the Noise Protocol.

Different levels of noise protection apply depending on the land use zoning and the amount of background noise at the noise sensitive area.

The noise limits are primarily set according to the local land use zones surrounding the noise sensitive area. The influence of surrounding land uses is based on the purpose of the local land use zones in a Planning Scheme, including the degree of industrial use permitted. Higher noise levels are generally allowed close to industrial areas, and lower levels apply in residential or rural living areas.

From 1 July 2021, the proposed use of land where a public acquisition overlay applied to the land and other specific uses of land set out in the old framework under SEPP N-1, are no longer factored in the calculation of noise limits in major urban areas.  

While the noise limits provide reasonable protection, they are not set to preserve the existing ambient sound environment or attain inaudibility.

Where noise limits apply

Noise limits apply in noise sensitive areas that include places where people live, learn or stay for recreation purposes. They include: 

  • residences or other places where people reside or sleep 
  • child care centres or schools 
  • campgrounds and caravan parks in rural areas.

For the definition of noise sensitive area, see regulation 4. 

Compliance with the noise limits for commercial, industrial and trade premises is usually assessed at a noise sensitive area. However, the Regulations also enable the assessment of noise for commercial, industrial and trade premises at a location other than a noise sensitive area. This is referred to as an alternative assessment location.  

The use of an alternative assessment location is described in the Noise Protocol (clauses 57 to 62). 

EPA publication 1997 Technical guide: Measuring and analysing industry noise and music noise describes when and how to assess noise at an alternative assessment location.

The noise limit must not exceed 55 dB(A) at night

The night period noise limit must not exceed 55 dB(A), as set out in regulation 118(3). This protects sleep and reduces the risk of harm to human health. It applies to both major urban areas and rural areas, regardless of the land use zoning or background level.

This limit may be relevant in locations within major urban areas exposed to heavy traffic, where the noise limit is set as a margin above background noise. Instead of the noise limit increasing with the traffic noise levels, the night period noise limit of 55 dB(A) comes into effect to protect human health and sleep at night. 

Regulation 118(3) may also come into effect when a noise sensitive area is located within an entirely industrial area. 

Cumulative noise

The noise limits apply to the cumulative noise from all commercial, industrial and trade noise (combined total industry noise) received at a noise sensitive area. As noise from multiple premises can add together, this means each site may need to be quieter than the noise limits.
 
If two or more commercial, industrial or trade premises contribute to the effective noise level, regulation 119 requires that a person in management or control of one or more of those premises must take all reasonable steps to ensure that the contribution from each of the premises, when combined, does not exceed the noise limit for the noise sensitive area. 

The Noise Protocol sets out how to take into account the cumulative contribution of noise from commercial, industrial and trade premises using an alternative assessment location and alternative assessment criterion (clauses 57 and 62). 

EPA publication 1997 Technical guide: Measuring and analysing industry noise and music noise provides further information on assessing noise contributions from multiple premises.

Major urban areas and rural areas

The Noise Protocol sets noise limits using different methods based on whether the noise sensitive area is located in a major urban area or in a rural area (regardless of the location of the commercial, industrial or trade premises assessed).

A major urban area generally includes towns and cities with a population of more than 7,000 (subject to the specific requirements of the definition in the Regulations). Rural areas are all land in Victoria that are not within a major urban area. The major urban area boundaries are available on EPA’s website.

The base noise limits, which are the lowest decibel values that can be set as the noise limits for the corresponding operating time period, are set out in regulation 118(2). The base noise limits are lower in rural areas than in major urban areas, reflecting the lower ambient sound levels in less urbanised areas.

 

Noise limits in rural areas of high traffic noise

The rural area method for setting noise limits places constraints on how loud industry noise may be in areas of high traffic noise. It helps to manage the overall level of noise residents are exposed to by managing industry noise emissions relative to the level of traffic noise. This only applies to proposed new industrial premises. It does not apply when assessing extensions or upgrades to existing premises.

The reference values for high traffic noise areas given in clause 26 of the Noise Protocol do not represent an assessment of what levels of traffic noise are appropriate and are not targets for traffic noise management.

Instead, when a new commercial, industrial or trade premises is proposed and the noise sensitive area of concern is affected by noise from a major road, freeway or highway, and this road is expected to be moved or bypassed, the industry proposal should design for a lower noise level suitable to the expected future background levels.
 

Noise limits for utilities

Under the Regulations, utilities are commercial, industrial and trade premises and the noise limits determined using the methods in the Noise Protocol apply. 
Utilities include infrastructure used: 
  • for telecommunications
  • to transmit or distribute gas or oil
  • to transmit, distribute or store power, including battery storage
  • to collect, treat, transmit, store, or distribute water
  • to collect, treat, or dispose of storm or flood water, sewage, or sullage.
In rural areas, a specific method applies to setting noise limits for utilities (Noise Protocol clauses 29 to 32). It accounts for the different expectations people may have about noise from agricultural uses compared to noise from utility installations, which are not connected to the local land resources in the way agriculture is. In a Farming Zone, Rural Activity Zone or Greenwedge Zone, the method results in lower noise limits for utilities than for agricultural activities.

 

Noise limits for earth resources 

In major urban areas the noise limits for commercial, industrial and trade premises apply to mines and quarries. 
 
In rural areas the Noise Protocol provides a method for setting noise limits specifically for earth resources premises (clauses 33 to 36). This method recognises that mines and quarries are located according to the availability of a mineral or stone resource, rather than planning scheme provisions, which means a graduated, planning scheme–based approach would not be appropriate.

The Noise Protocol also provides variations for particular open-air activities at mines and quarries where there is significant open-air surface activity (clauses 52 to 55). These variations apply to mines and quarries across Victoria, in major urban areas and rural areas. They must not be applied where the noise limits can be achieved. 

The variations recognise that some activities are unavoidably noisier than others, but they still need to be managed appropriately. The variations also help to balance the short-term additional impact associated with the construction of noise-control works against the long-term noise-reduction benefits they offer.

The variations are also relevant to landfill operations; however, the noise limits that apply to landfills are determined using the method for commercial, industrial and trade premises—not the method for earth resources premises.

 

Noise limits for emergency equipment

When noise from commercial, industrial and trade premises is assessed, noise from equipment used in relation to an emergency must not be taken into account under regulation 117. This applies to noise emitted during the emergency. However, noise limits apply to testing or maintenance of emergency equipment as specified in the Noise Protocol (clauses 37 and 38).

 

4.5. Effective noise level

The effective noise level means the level of noise emitted from a commercial, industrial or trade premises and, if appropriate, adjusted to take into account the character and duration of the noise, and the measurement conditions, as determined in accordance with the Noise Protocol.

The adjustments take into account the character of the noise (such as more annoying tones or hammering), where the noise is measured (near reflecting surfaces or indoors), and how long it is emitted in a half-hour period. For example, when there is a prominent tonal character to the noise (such as whining or humming), a +5 decibel ‘penalty’ is applied to the measured noise (see Noise Protocol, clause 83).

The effective noise level is the sum of the measured level and any adjustments that apply. When determined at a noise sensitive area, this is the level that is compared to the noise limits to determine if the noise emitted is unreasonable noise as prescribed in the Regulations. The effective noise level is assessed and compared to the relevant noise limit for each of the day, evening and night periods separately. Only the times when the industry operates, or proposes to operate, are assessed.

Refer to the Noise Protocol for the methods for assessing the noise. EPA publication 1997 Technical guide: Measuring and analysing industry noise and music noise describes how to use the Regulations and Noise Protocol to predict, measure and assess noise from commercial, industrial and trade premises.
