There’s been plenty of talk – rightfully so – of the annoying swarms of bees that are the Vuvuzela horns you hear during the 2010 World Cup. There reportedly have been more than one million sold since the Cup began last week.
Nothing short of a ban on the horns (it’s not going to happen) would help the players, broadcasters and fans at the matches, but as TV viewers, we thankfully have technology on our side. A German sound engineer has created a 45-minute sound file you can buy and play during broadcasts. It’s supposed to cancel out the sound using active noise control, the same way noise-canceling headphones work.
But thanks to another more industrious method, also originally posted by a German (Google translated page), you can just set your computer, stereo or TV equalizer to filter out the sound of the Vuvuzelas.
Apparently, all you have to do is duck your equalizer by at least 40dB at 465Hz and 235Hz. If you are using your TV equalizer and it doesn’t offer those specific Hz levels, you can probably get away with approximating.
If you really want to get nerdy with it, here’s a video from Lifehacker that shows the before and after results:
