    Tullamarine freeway closure The Tullamarine Freeway will be closed to all traffic between Terminal Drive Exit and Sunbury Road (outbound) from Thursday 18 January 2100 (9:00pm) to Sunday 21 January, 0600 (6:00am).  Access to the airport for all travellers will be affected.

    Aim Of Melbourne Airport Noise Tool

    This interactive tool provides information about how noise from the operation of Melbourne Airport affects the community, both now and in the future

    The third runway will have an effect on how and where noise is experienced around the airport. The tool will show the predicted level of noise with a three runway system operating at full capacity in comparison to the current two runway configuration.

    The tool allows you to see where your home is positioned in relation to the forecast aircraft noise, and how we expect this to change from today (with two runways) and beyond 2018 (with our proposed third runway).  By entering the details of your suburb into this interactive tool, you will see operational noise levels, ANEF and N contours.

    The data used in the tool represents historical and forecasted movements and indicative flight paths.  While care has been taken developing this data, it may change from time to time. The data is provided for information purposes only and should not be relied upon for personal  medical, legal or financial reasons.

    What are the ANEF, N contours & Operational Noise Levels?

    Australian Noise Exposure Forecast, otherwise known as the ANEF
    It is the current Australian standard for forecasting aircraft noise. The ANEF is a forecast of the cumulative noise effect of a full year of airport operations, including changes in weather patterns and airline schedules. The resulting ANEF is therefore a measure of the total noise exposure over a 12-month period divided by 365 to show an average annual day. The ANEF is a forecast showing the noise levels of the four runways that have been planned for the airport since 1990, despite only two runways being operational currently. This is so governments and community can see areas that may potentially be affected by noise in the future, for land use planning purposes.

    ANEF contours are given values of 20, 25, 30, 35 and 40. The higher the contour value, the greater the noise. The Airports Act says that the ANEF contour 30 is a ‘significant’ noise level.

    N contours
    To supplement the ANEF and better describe aircraft noise levels, the Australian Government, through the Department of Infrastructure and Transport in consultation with industry and the community has developed the N contour system. The N contours measure the number of aircraft noise events per day – exceeding 70, 65 or 60 decibels. This will help the user to see what level of noise impact can be expected where they live into the future.

    N60 = 100 or more events exceeding 60 decibels per day
    N65 = 50 or more events exceeding 65 decibels per day
    N70 = 20 or more events exceeding 70 decibels per day
    Night contours = 6 or more events exceeding 60 decibels per day

    Operational Noise Levels 
    These noise contours show us the current operational noise levels from the airport’s operation (based on historical data - ANEI) and potential operational noise levels with a third runway (based on forecast data - ANEC).
