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].

FAPE is defined in the Code of Federal Regulations (7 CFR 15b.22) [6] as "the provision of regular or special education and related aids and services that (i) are designed to meet individual needs of handicapped persons as adequately as the ...
This technique requires an adaptive filter to generate a signal accurate enough to effectively cancel the echo, where the echo can differ from the original due to various kinds of degradation along the way. Since invention at AT&T Bell Labs [5] echo cancellation algorithms have been improved and honed. Like all echo cancelling processes, these ...
Noise-cancelling aviation headsets are now commonly available. [5] [6] In 1989, Bose Corporation introduced its Aviation Headset Series I, which became the first commercially available ANR headset. [7] Several airlines provide noise-cancelling headphones in their business and first-class cabins. Bose started supplying American Airlines with ...
