ANEF and ANEI

Australian Noise Exposure Forecast (ANEF)

ANEF charts are contour maps that show a forecast of aircraft noise levels that are expected to exist in the future. They are prepared for all of the major and regional airports and most of the minor aerodromes that have a large number of annual movements.

ANEFs are prepared by airport owners. For the major airports the ANEF forms part of their Master Plan and is updated every five years.

Airservices has responsibility for endorsing the technical accuracy of ANEFs, but does not assess any of the data or assumptions in a qualitative way.

ANEFs are primarily used by local Councils for land use planning.

Australian Noise Exposure Index (ANEI)

ANEI charts are contour maps that show actual historical aircraft noise levels over a given period of time.
