Abstract
A method of active noise reduction is described which comprises receiving an audio signal (132) to be played, receiving a noise signal (105, 107, 116, 118, 126), indicative of ambient noise (111), from at least one microphone (104, 106), and generating a noise cancellation signal (114) depending on both, said audio signal (132) and said noise signal (105, 107, 116, 118, 126).
