Airservices collects noise and operational data from twelve noise monitors (Environmental Monitoring Unit, EMU) around Sydney Airport. Noise monitors are grouped below according to their direction from the airport.
Noise monitoring is not conducted to determine compliance with aircraft noise regulations – there is no regulated maximum level for aircraft noise. Rather, aircraft operating in Australia are required to meet noise standards imposed through the Air Navigation (Aircraft Noise) Regulations 1984. These regulations stipulate compliance with international noise standards that apply to the design and production of aircraft, and specify the amount of noise that may be emitted by an aircraft type or model. Aircraft that do not meet these standards are prohibited from engaging in air navigation in Australia unless exceptional circumstances apply. This is administered by the Department of Infrastructure and Regional Development.
Noise monitoring is conducted to:
- determine the contribution of aircraft noise to the overall noise that a community is exposed to
- provide information to the community about aircraft noise and operations
- help local authorities make informed land use decisions
- inform estimates of the impact of changes to air traffic control procedures
- validate noise modelling
- inform the determination of aircraft noise policy by government and assist in the implementation of legislation.
