Development - Australian Noise Exposure Forecast (ANEF).
Homeowners should be familiar with their local Australian Noise Exposure Forecast (ANEF) maps, which provide the best information about aircraft noise exposure near Defence bases.
ANEF maps provide a forecast of noise for a future year, made by both civilian and military aircraft for that location. They do not show every flight and homeowners with properties outside of the ANEF map zones may still experience aircraft noise.
One of the most effective ways to reduce the impact of aircraft noise is through proper land planning by local Town Councils.
Department of Defence ANEF maps
ANEF maps are usually updated every five to ten years, as a result of new noise information (for example, an older aircraft may be retired and a new aircraft may be introduced) or when the current map passes its forecast date. Because ANEF maps are a forecast, the map will always include the year that is forecasted. For example, the RAAF Base Williamtown 2025 ANEF is a forecast for the year 2025, and incorporates noise modelling for the F-35A Joint Strike Fighter.
Properties purchased near airports and bases are always likely to experience some degree of aircraft noise, which will increase or decrease with changes in use.
ANEF Maps should be read in conjunction with Australian Standard 2021 – 2000 Acoustics - Aircraft Noise Intrusion - Building Siting and Construction.
