Vuvus are a no no

The World Cup has not been with us long, but almost as soon as it started people were complaining about the noise coming from the omnipresent Vuvuzela horns.

Because the horns play one tone, one long annoying continuous tone, users can filter its range out without having too much of an impact on important things like commentary and inter-player swearing, according to the German firm that came up with the idea to flush the TV sound output through a computer.
