How to Enjoy the World Cup Without Vuvuzela

vuvuzela No, we have not become a sports blog, but when technology comes to rescue millions of soccer-fans, we can’t remain silent.  And by not remaining silent I don’t mean blowing our own horn Vuvuzela🙂

The Vuvu has caused quite a kerfuffle at the World Cup this year. TV networks and broadcasters are fed up, those live at the stadium are in danger of hearing damage ( this thing creates 130 decibel noise, which is above the human pain threshold), the FIFA is considering handing out free earplugs to dampen the noise.

While we can’t help those in the stadium in South Africa, there’s a very simple solution to the rest of the world following the game on TV or the Internet.  You need a device that has an equalizer: better TV sets do, if yours does not, try to hook audio to your Sound system, or use a computer.

EqualizerThen all you have to do is filter out (reduce) the 300 Hz range – apparently all Vuvus shriek at this frequency.

If you don’t have access to an equalizer, you may try fighting sound with sound: an online company claims to generate noise-cancellation sound that is “ a wave with the same amplitude but with inverted phase to the original sound.  The waves combine to form a new wave, in a process called interference, and effectively cancel each other out -an effect which is called phase cancellation

Warning: we have not tried the anti-vuvuzela filter and can not make any claims to its efficiency.

Update: more options @ GigaOM .
