Presenting the MAUS project on traffic auralisation

In the MAUS project, we have developed a prototype of a traffic auralisation tool. The idea is to realistically imitate the sound of traffic, to give an idea of how it will sound in cases that have not been realised yet, and to show the effects of various noise-reducing measures. We have previously given a simple description of how the tool works together with sound examples on this blog.

In early December, we presented a paper and a poster on the MAUS auralisation tool at the 18th International Conference on Digital Audio Effects (DAFx-15) here in Trondheim. This conference was organized by the Music Technology and Acoustics groups at NTNU.

Hvor kommer lyden fra?

Hvor kommer lyden fra?

Lukk øynene dine og hør på lydene rundt deg. Kan du høre hvor de kommer fra? Hvilken retning, og hvor langt unna lydkilden er? Hørselen vår er et eksepsjonelt instrument som ikke bare har et stort dynamisk område, men også evnen til å lokalisere lydkilder. Vi kan faktisk oppfatte retningen til en lydkilde med en nøyaktighet ned mot én grad. Denne evnen er i stor grad mulig fordi vi ikke bare har ett øre – men to! Dette gjør at vi klarer ganske så godt å skille lyder vi er interessert i, typisk tale og musikk, fra uønsket lyd som kommer fra andre retninger.

How do you imitate the sound of traffic?

How do you imitate the sound of traffic?

We previously wrote about the MAUS project, where we are building an auralisation tool to simulate the sound from virtual noise sources outdoors in order to give a realistic representation of how a future noise source will sound when it has been developed. One such noise source that we have been working on is traffic, one of the biggest issues in environmental acoustics. But how do you simulate the sound of traffic on a computer?
