noise

After watching the first game of the FIFA worldcup I was very annoyed by the sound of the Vuvuzelas. A theoretical question came up about filtering that noise out of the sound stream.

What algorithms are needed to remove such a "constant" noise and is it possible to keep the quality of other background sounds?
