Noise from refrigeration equipment needs to comply with the permitted noise levels and not cause a nuisance to neighbours.

Permitted noise levels

If the noise at a premises is over the following levels, a fine or notice may be issued to the responsible person:

• 7am to 10pm - no more than five decibels (A) above the background noise level
• 10pm to 7am – no more than three decibels (A) above the background noise level.

How to reduce noise levels

You can help to reduce noise by:

• selecting a quieter model
• choosing the refrigeration equipment location carefully (avoid placing near neighbouring bedroom windows, offices, multiple walls and corners)
• parking truck mounted units at a depot or away from noise sensitive areas
• performing regular maintenance on refrigeration equipment
• installing a solid fence or barrier
• installing an acoustic enclosure - check with the manufacturer or installer for advice
• modifying equipment – check with the manufacturer or installer for advice.
