  • This technology picks up sound via a strategically placed microphone, which is interpreted and inverted by a DSP processor. The exact opposite sound is pumped back out towards the source by speakers, the net result being an acoustically shadowed area or quiet zone created by the two colliding reverse phase sound waves cancelling each other out.

  • sound travels in waves, all you have to do is play the sound with waves that are in anti-phase and they cancel out making silence, its used in fighter jets. the sound of the engine is made practically silent so the pilot can speak at a reasonable level :)

  • Too bad... I quite like most noises...

  • impossible!!!!
