Active Noise-Cancellation Technology takes a more analytical approach to block out external noise. There are one or more microphones built into the headphones to detect external noise. By employing sophisticated electronic signal processing, an "anti-noise" signal is then generated to cancel out the external noise.
In essence, this leaves only the desired music or soundtrack audible to the listener. How effective this noise-cancellation capability works depends on the quality of the microphone pick-ups, the complexity of the noise-cancellation algorithm used for processing, and the signal latency being kept to an inaudible difference. The sonic performance of the headphones plays a major role as well.
In a pair of well-engineered noise-canceling headphones, you will hear your intended playback sans any background noise faithfully. The Aurvana X-Fi
noise-canceling headphones offers just that. Listen to the following demonstration to find out how effective noise-cancellation is employed in various usage scenarios.
