Auralisation: Motorway compared to highway at different distances

Highway and motorway noise at a distance of 30 and 100 metres

Listen to highway and motorway noise. The highway noise represents a two lane road (15,000 vehicles/24h at 80 km/h) The motorway noise represents a four lane motorway (59,000 vehicles/24 h at 110 km/h).

The example shows differences in traffic flow and speed at a distance of 30 and 100 metres.

Note: Due to the differences in traffic flow you should listen to the sound files continuously for some time – don’t make frequent jumps between the two sound files.


Please connect your headset to your computer. Make sure that the left and right channels are set correctly.

Start by pressing the black boxes. During playback you can jump between options.

You shoud not adjust the volume as this will change the adjustment you have already made in order to calibrate your system.
