Allowable noise levels
Protection of the Environment Operations (Noise Control) Regulation Operations Act 2000
Noise limits and time restrictions for usage of air conditioners are set by the above body. Councils are responsible for enforcing these limits at residential properties. If a cooling / heating system exceeds these limits, councils may issue the operator with a warning or notice. If the air conditioner continues to be used in excess of the noise and limits, councils are able to issue on-the-spot fines.
Air conditioners can be used during the following times:
Weekdays 7am to 10pm
Weekends and public holidays 8am to 10pm
The allowable noise level during 7am to 10pm is no more than 5dB(A) sound pressure level above background noise.
This is measured at the boundary between the owner and the neighbours’properties.
The allowable noise level during 10pm to 7am (or 8am) is zero dB(A) above background noise.
This is measured at the neighbours nearest habitable room or window. Ensure your unit is inaudible from neighbours’ homes if you require longer hours of operation. Some councils may impose other specific noise levels, PLEASE CHECK!!! |
