Adaptive noise cancelling is a signal processing technique that is highly effective in suppressing additive interference or noise corrupting a received target signal at the main or primary sensor in certain common situations where the interference is known and is accessible but unavoidable and where the target signal and the interference are unrelated, that is, uncorrelated [1] [2] [3].
The sudden absence of background noise gives the near-end user the impression that the line has gone dead. In response to this, Bell Labs developed echo canceler theory in the early 1960s, [ 4 ] [ 5 ] which then resulted in laboratory echo cancelers in the late 1960s and commercial echo cancelers in the 1980s.

The wavelength in air of sinusoidal noise at approximately 800 Hz is double the distance of the average person's left ear to the right ear; [1] such a noise coming directly from the front will be easily reduced by an active system but coming from the side will tend to cancel at one ear while being reinforced at the other, making the noise ...

Digital noise cancelling headphones reduce this problem with the inclusion of a software equaliser, also running on the DSP chip, to clean up the signal and improve the overall quality of audio produced by the headphones. Overall, Digital Noise cancelling headphones produce better fidelity sound than their analogue counterparts." Lance.
Adaptive feedback cancellation originated during the evolution of the hearing aid. The hearing aid became digital, and as such feedback cancellation was needed. In 1980 a directional microphone was introduced in the digital hearing aid, and adaptive feedback cancellation was created to block external noise that the microphone picked up. Today ...
