Abstract (en)
An active noise reduction apparatus (1) for a vehicle comprises a detecting device (11) configured to detect at least one reference signal which is indicative of at least one component of a noise (50) generated at a contact area (41) between a wheel (3) of the vehicle and a track (4) on which the vehicle is travelling, a sound emitting device (13, 13-1, 13-2) for emitting sound waves (60) towards the at least one contact area (41) between the wheel (3) of the vehicle and the track (4) on which the vehicle is travelling, and a control device (12) which is operatively coupled with the detecting device (11) and the sound emitting device (13, 13-1, 13-2). The control device (12) is configured to control the sound emitting device (13, 13-1, 13-2) for emitting sound waves (60) based on the detected at least one reference signal so as to reduce the at least one component of the noise (50) through active noise cancellation by the emitted sound waves (60).
