But more dynamic sound such as a voice, or perhaps your roommate's drums will not be effectively cancelled out. The reason for this is because the technology has a microphone which picks up the outside noise, reverses the phase, and then generates the reverse wave. The original sound wave and the reversed wave will essentially cancel out each other and you won't hear anything.<br><b>References : </b><br>http://en.wikipedia.org/wiki/Noise-cancelling_headphone Noise cancelling technology works for continuous sound, such as the hum of an air conditioner.
