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.
Graphical depiction of active noise reduction. Active noise control (ANC), also known as noise cancellation (NC), or active noise reduction (ANR), is a method for reducing unwanted sound by the addition of a second sound specifically designed to cancel the first.
Shopping for noise-cancelling headphones on a budget doesn’t mean you have to sacrifice performance. Case in point is the Anker SoundCore Life Q20. Case in point is the Anker SoundCore Life Q20.

In a noisy environment, both microphones receive noise at a similar level, but the primary mic receives the desired sounds more strongly. Thus if one signal is subtracted from the other (in the simplest sense, by connecting the microphones out of phase) much of the noise is canceled while the desired sound is retained.
Noise canceling: If both the noise and the signal are received by an electronic or digital medium, noise can be filtered from the signal electronically and retransmitted without the noise. See noise-canceling microphone. Helicopter pilots rely on this technology to speak on the radio. See also. Acoustic signature; Noise reduction, for ...
