Noise modelling tool step by step guide

1. Enter your address using the 'address' field

2. A pop-up box will appear showing the ANEC information for the year 2030, based on the ANEC modelling method for the 'Prefer 05' operating direction (departures to the north east and arrivals from the south west).

3. The noise modelling tool presents information based on the Australian Noise Exposure Concept (ANEC). This information is available for the years 2030 (stage 1 airport development), 2050 (one runway at capacity) and 2063 (long term development, with two runways).

Using the left hand menu, you can view predicted ANECs based on each of the options outlined above.

Interpreting the noise modelling tool

Australian Noise Exposure Concept (ANEC)

The Australian Noise Exposure Concept (ANEC) takes into account the anticipated number of movements, types of aircraft, and flight paths including the height of aircraft for arrivals and departures. ANECs are useful for land use planning.

The example below shows the ANEC in relation to Silverdale1, on the ‘Prefer 05’2 operating mode in the year 2030.

It shows that Silverdale is outside the ANEC 20 band (in which residences would be acceptable without conditions).

ANEC in relation to Silverdale , on the ‘Prefer 05’ operating mode in the year 2030.


To find out more about the flight path design process, read the factsheet Flight paths for Western Sydney Airport.

1. Note the example shows Ridgehaven Road in Silverdale.

2. Information is also available for the ‘Prefer 23’ operating mode. For this location, Silverdale remains outside the ANEC 20 band for the different operating modes in the year 2030.
