An ANEI is determined through the same methodology as an Australian Noise Exposure Forecast (ANEF), but are based on historic operations.

The ANEF/ANEI charts show the cumulative noise effect of a full year of operations to take into account seasonal changes in weather patterns and airline schedules. The resulting contours are a measure of the total noise exposure over a 12-month period divided by 365 to show an average annual day.

The contours shown highlight ANEI for operations at Melbourne Airport during 2024.
