If you’re trying to find some peace and quiet when working from home, at the office, at school or during your morning commute, then a great pair of wireless noise-cancelling headphones can work ...
Whether you prefer the "cone of silence" of over-ear cans or the comfort of earbuds, noise-canceling headphones will filter out the cacophony and let you focus.
Adaptive feedback cancellation is a common method of cancelling audio feedback in a variety of electro-acoustic systems such as digital hearing aids. The time varying acoustic feedback leakage paths can only be eliminated with adaptive feedback cancellation. When an electro-acoustic system with an adaptive feedback canceller is presented with a correlated input signal, a recurrent distortion ...
Adaptive noise cancelling Adaptive noise cancelling is an unorthodox 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 ...
Noise -cancelling headphones alongside a carry case. Noise-cancelling headphones are headphones which suppress unwanted ambient sounds using active noise control. This is distinct from passive headphones which, if they reduce ambient sounds at all, use techniques such as soundproofing . Noise cancellation makes it possible to listen to audio ...

The internal electronic circuitry of an active noise-canceling mic attempts to subtract noise signal from the primary microphone. The circuit may employ passive or active noise canceling techniques to filter out the noise, producing an output signal that has a lower noise floor and a higher signal-to-noise ratio .
Over-ear headphones Development of the company's noise cancelling headphones (and first over-ear headphones) began in 1978 when the chairman, Amar Bose, tried a set of airline-supplied headphones during a flight and found that engine noise from the aircraft prevented the music from being enjoyed.
