Abstract
Embodiments of the present invention provide a noise cancellation system for a vehicle comprising a noise prediction means (110) and an audio processing means (120) for outputting a noise-cancelled signal (121) based on received noise and audio signals (132, 134, 141) received from noise and audio input means (130, 140).
