Anti Vuvuzela Filter
The
Name '''Anti Vuvuzela Filter''' is
standing for a filter who is eliminating the noise of the Vuvuzelas and is
named after this WebSite “AntiVuvuzelaFilter.com” who delivered such a Filter.
During the
FIFA World Championship 2010 in Southafrica, this word becomes a central word
against the Vuvuzela Noise in style of a filter.
The "Anti Vuvuzela Filter" was produced in an German sound studio.
The
Vuvuzela sound like all other steady noise is a pressure 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.
