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. The concept was first developed in the late 1930s; later developmental work that began in the 1950s eventually resulted in ...
Adaptive noise cancelling. 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 ...
Bose has done exactly that with its QuietComfort line of noise-cancelling headphones — and for good reason. The QC35 and QC35 II set the bar for active noise cancellation (ANC) when it comes to ...
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 ...
AirPods Max. Apple’s AirPods Max are premium, well-designed headphones that incorporate all of the best features you find on standard AirPods: solid noise cancelation, spatial audio and easy ...
The QC Ultra Earbuds are slightly less effective on human voices, but that’s true of many noise-canceling earbuds. But with any kind of constant hum, and many irregular sounds, these earbuds ...
Bose offers 11 levels of noise cancellation on the QC Earbuds, just like it does on its headphones. You can set three levels of favorites inside the Bose Music app, and a double tap on the left ...
Active sound design is an acoustic technology concept used in automotive vehicles to alter or enhance the sound inside and outside of the vehicle. Active sound design (ASD) often uses active noise control and acoustic enhancement techniques to achieve a synthesized vehicle sound. The typical implementations of ASD vary, from amplifying or ...
