The easiest method costs €2.95. Vuvuzela haters can visit antivuvuzelafilter.com, plunk down their cash, and download a 45-minute MP3 file. This must be played back during each half of a football match, preferably from a speaker right next to the television, and the "specially designed Vuvuzela noise-cancellation sound is a wave with the same amplitude but with inverted phase to the original sound." In other words, you get active noise cancellation.
I wonder if this works...

scam.

I don't think all of them put out the same tone, so I don't know how noise cancellation is possible

These been around since the 70s

There's an interesting dichotomy somewhere in this...

I dont understand...
people complaining about these vuvuzelas things, yet regeton is blowing up

for cancellation to work, the wave has to be 180 degrees out of phase. inverted phase is only meaningful if the two waves are perfectly time-aligned.

of course it wouldn't work. the sound would have to be an exact opposite of every change in scale and tone of whatever's coming out of the tv or whatever, and that would be impossible to predict.
in order for something like that to work it would have to generate the anti-wave dynamically based on original input
- works...just tried it. it makes a difference for the better. It's not like you can hear them but it make a diff.BannedKappa
