Vuvuzela filtering for World Cup Answered
The biggest complaint I keep hearing about the World Cup is about the vuvuzelas, plastic horns that get blown for everything and nothing. This makes me almost glad that I'm missing practically every game because of the broadcast times and the fact that my TV only has bunny ears for reception.
Well, PopSci has found that some people are fighting back by filtering out the frequencies of the vuvuzelas at 233 Hz, 466 Hz, 932 Hz, and 1864 Hz. It's a good enough trick that it makes me almost want to upgrade my setup so that I can try it out.
