It is implemented by filtering the frequencies 233, 466, 932 and 1864Hz using a band-stop filter (notch filter) Was provided the info from: http://www.afterdawn.com/news/article.cfm/2010/06/14/vuvuzela_buzz_ruining_your_world_cup_get_rid_of_it It is not perfect, but once active, you can finally hear people cheering..

How to use it: Go to the settings -> general in the audio section. Activate Advanced Audio and check the Vuvuzela box. Validate all pages to the end.
