BadVibes is a new science project from Salford University that aims to find out just that. People can log on to the BadVibes website at www.sound101.org where they listen and vote on a collection of awful sounds, use the horrible sound mixer and even download horrible sound effects as ringtones.

But as Professor Trevor Cox from the University’s Acoustics Research Centre explained, there’s a serious side to the research as well.
