If your event is outdoors and has amplified music, a speaker system providing directions to participants and or mechanical equipment will be operating, then you will be required to develop a Noise Management Plan as part of your Event Plan.
The management of noise associated with your event should be developed in accordance with the Environmental Protection Authorities (EPA) Noise Level Guidelines.
Noise Level Guidelines and how do they relate to events
The Noise Level Guidelines in relation to outdoor events is set by the State Environment Protection Policy which is administered by the Environmental Protection Authority.
The following information has been summarised from the Victorian Government Gazette No: S43 August 1989 Environmental Protection Act 1970.
In this policy the Environmental Protection Authority, advises that the noise level guidelines in relation to amplified sound are for a:
- five hour period between the hours of 9:00am and 10:00pm from Monday to Thursday
- ten hour period between the hours of 10:00am and 11:00pm on a Friday or a Saturday
- ten hour period between the hours of 10:00am and 10:00pm on a Sunday
During any of these times the noise level limit for outdoor venues is set at 65dB (A).
Noise should not exceed this level inside the closest residence or business to the event site.
There are also general noise level guidelines in relation to machine operations or building such as ‘noisy machinery’, that is: trucks, earth moving equipment, hammering, are only permitted between the hours of:
- 9:00am and 10:00pm from Monday to Thursday for a five hour period
- 10:00am and 11:00pm on a Friday or a Saturday for a ten hour period
- 10:00am and 10:00pm on a Sunday for a ten hour period.
During any of these times the maximum noise level limit for outdoor venues is 65dB (A). This noise level should not be exceeded inside the closest residence or business to your event site.
Developing a noise management plan:
- Identify the groups that are likely to be affected (this could include residents, business and wildlife)
- Show on the site plan the position and direction of speakers, ideally speaker horns be faced towards open areas, ie. water.
- List the times that sound testing will be undertaken (also include in your Event Build Schedule)
- List the times that amplified sound will be used during the event program
- Document a noise reporting and control procedure for when the noise is being generated. It is likely that a professional noise consultant will be required to measure the noise of your event during the sound testing, during the event and at specific locations. Should the noise levels exceed 65dB(A) at any time the consultant should immediately advise you or the sound technician to lower the sound levels. You may also need to provide a post event noise report to the City’s Events Unit.
