Abstract
La présente invention concerne un système, un procédé et un support de stockage pour une annulation de bruit dans un véhicule qui comprennent la détermination d'une forme d'onde d'une première onde sonore à un premier emplacement, le calcul d'une autre forme d'onde de la première onde sonore à un second emplacement d'un opérateur sur la base de la forme d'onde de la première onde sonore au premier emplacement et d'une première distance entre le premier emplacement et le second emplacement, la génération d'au moins un signal de commande sur la base de l'autre forme d'onde déterminée de la première onde sonore au niveau du second emplacement et la génération d'une seconde onde sonore sur la base du au moins un signal de commande. Une forme d'onde de la seconde onde sonore est formée pour annuler la première onde sonore au niveau du second emplacement. La première onde sonore est générée par une source de bruit.
