How to cancel out the vuvuzela on your TV
So you’ve started watching the World Cup in South Africa, you're enjoying the games, but the thing that's spoiling it for many are those vuvuzelas. Until FIFA gets around to banning them, there is another way of cancelling out the sound on your television, if suggestions circulating the web are to be believed.
We saw these instructions circulating Twitter from @Cliff, suggesting you have to do the following to get rid of the vuvuzela noise:
Step 1: enter the sound settings for your TV, find the equaliser.
Step 2: drop the 300Hz channel (which Samsung TVs have, second from left), and raise the adjacent levels.
Step 3: save as a custom setup (if you can).
We gave it a try on a Samsung TV, and while it doesn't remove the vuvuzela noise completely, it does tone it down. It also takes some of the depth out of the commentary, as voices sound less rounded and full bodied, perhaps no bad thing.
The settings should work on most TVs where you can make changes to the sound levels in this way, but if they don't on your television you do have another option. Download and play an MP3 track that will work as a jamming signal.
For 2.95 euros, you can get yourself the Anti Vuvuzela Filter, a specially designed noise-cancellation sound, consisting of a wave with the same amplitude but with inverted phase to the original sound.
It works by by creating interference so they effectively cancel each other out - an effect called phase cancellation.
For your money, you get an audio file that's 45 minutes long, ready to load onto your MP3 player or phone which you then plug into a speaker dock or hi-fi placed near the TV. (Disclaimer: we didn't actually try this, so don't blame us if you lose your money or end up with spyware galore.)
Of course, if you enjoy that noise, and think it's the spirit of the tournament in South Africa, then you don't need to do anything. You could even boost that 300Hz channel, or annoy your mates at work. vuvuzela.ytmnd.com/ is a website that lets you do just that for as long as you can take it, with as they claim "the most annoying noise in the world."
