Title (EN) ACTIVE ROAD NOISE CONTROL
(FR) RÉGULATION ACTIVE DE BRUIT DE ROUTE
Abstract:
(EN) An active road noise control system and method for a vehicle includes generating a microphone sense signal representative of road noise occurring in or at a wheel well of the vehicle, and iteratively and adaptively processing the microphone sense signal to provide a noise reducing signal. The system and method further include generating from the noise reducing signal with a headrest loudspeaker arrangement disposed in a headrest in an interior of the vehicle, noise reducing sound at a listening position in the interior of the vehicle.
(FR) L'invention concerne un système et un procédé de régulation active de bruit de route pour un véhicule, lesdits système et procédé consistant à générer un signal de détection de microphone représentatif d'un bruit de route se produisant dans ou au niveau d'un logement de roue du véhicule, et à traiter de manière itérative et adaptative le signal de détection de microphone pour fournir un signal de réduction de bruit. Le système et le procédé consistent en outre à générer, à partir du signal de réduction de bruit, avec un agencement d'enceinte d'appui-tête disposé dans un appui-tête à l'intérieur du véhicule, un son de réduction du bruit à une position d'écoute à l'intérieur du véhicule.
