When the sound pressure of the noise wave is high, the cancelling wave is low (and vice versa). The net displacement of the medium at any point in space or time, is simply the sum of the individual wave displacements. Series Wiring the waves will obliterate each other but they will still exist, they just won't be moving they would just change form (energy cannot be destroyed it can only change form) so when the waves meet they will cancel each other so sound will change to potential and kinetic will change to sound or whatever. Let’s focus on the spaced pair formation in which both microphones are an equal distance from a sound source. What is Phase Cancellation? It does not cancel the surrounding noises; however the sound is so good, so the surrounding noises are easily ignored.
