How vuvuzela free world matches can be enjoyed
Whatever FIFA president says, people don’t like the annoying disturbance of vuvuzela during the match. So people are looking for an alternative solution to get rid of it.
antivuvuzelafilters.com is providing a service with the technology of cancelling the sound wave of vuvuzela by a special method. This interested viewers need to pay €2.95 to get this software. First they need to download a mp3 file which is necessary to be played during the match. This technology is termed as ‘active noise cancellation”. Active noise cancellation depends on sampling ambient sound and reproducing that sound exactly out of phase with the original; the result is that the sound waves cancel each other out.
Popular science gave a different but more difficult solution which is first given by a German Blog ‘Die Surfpoeten’. They use a method of filtering out the most common frequencies of the horn like 233, 466, 932, and 1864Hz. The filters are set up in a program like Logic Express where all audio signals are by passed through a secondary PC for processing of sound.
Lastly if anyone wants a free of cost offer, then ‘JACK audio connection kit’ would be the best solution for him.
Along with all these offers Professor Trevor Cox from the University of Salford, a Acoustic expert don’t think that it’s possible to avoid vuvuzela. So adviced, “Be Zen about it; accept vuvuzelas as part of the World Cup soundscape and pour another beer” in in the Daily Telegraph.
