Blestemul fonic de la Campionatul Mondial de Fotbal 2010 din Africa de Sud – vuvuzela – pare să aibă o nouă soluţie după the red button-ul BBC. Una bucată filtru antivuvuzela la preţ de 2.95 Euro care face următoarele:

How does it work?

The Vuvuzela sound like all other steady noise is apressure wave, which consist of a compression phase and a rarefaction phase. Our specially designed Vuvuzela noise-cancellation sound is a wave with the same amplitude but with an inverted phase to the original sound. The waves combines to form a new wave, in a process called interference, which effectively cancel each other out  – an effect which is called phase cancellation.

Depending on the circumstances the resulting soundwave may be so faint as to be inaudible to human ears.

What do you need?

Just download our specially designed Vuvuzela noise cancellation MP3 and play it back on your home stereo system, computer, iPod, iPhone etc.

The speaker with the Vuvuzela noise-cancellation sound should be located next to your TV.

For best results our Vuvuzela sound cancellation track should have the same audio power level as the source of the unwanted sound.

What do you get?

You get our highly acclaimed and professional designed 45 minutes Vuvuzela noise cancellation MP3 to get rid of the annoying Vuvuzela trumpet noise. (for the second half of the match, just play back the track from the beginning)

And on top of this genius noise cancellation tool, you will receive a piece of innovative Internet TV Software FOR FREE!
