Noise- cancel-headphones use advance d filtering techniques to o reduce unwanted ambientsound. Adaptive filtering is a key method that it dynamically justations to o changing noise environment, providg a bettcr listening experience. This articles descripts that practicail applicatio o f adaptive file filtering in n nois- cancelling hephones.

Grundlag for tilpasning af filtering

Det er vigtigt, at der er en sammenhæng mellem de forskellige former for teknologi, og at der er en sammenhæng mellem de forskellige former for teknologi, der er relevante for den enkelte sektor.

Implementation in Headphones

Det er ikke-annullerede headphones, microphones pick up ambient sounds. An adaptive filteret processes these signal to product an antinoise coefficients in real. Algithms ligner denne Leastt Mean Squares (LMS) ar e common use to to adjust fileter coefficients in real-time. Det sikrer, at de antinoise signal forbliver synkronized with thee external noise.
