Title
(EN) ACTIVE SOUND CONTROL
(FR) CONTRÔLE DU SON ACTIF
Abstract
(EN)
An apparatus for controlling sound within a vehicle includes an acoustical damping device operable to determine a measured sound. The acoustical damping device is operable to output a noise canceling signal to a vehicle audio system to dampen the measured sound. A sound controller is operably coupled to the acoustical damping device and is configured to automatically receive an environment signal from an environment sensor. The sound controller is configured to determine an operating mode of the vehicle based on the environment signal. The operating mode is selectable from an operating mode list that includes a stress operating mode and a calm operating mode. The sound controller is configured to cause alteration of the noise canceling signal and reduction in damping in the stress operating mode with respect to the calm operating mode.

L'invention concerne un appareil pour contrôler le son dans un véhicule, l'appareil comprenant un dispositif d'amortissement acoustique conçu pour déterminer un son mesuré. Le dispositif d'amortissement acoustique est conçu pour envoyer un signal de suppression du bruit à un système audio d'un véhicule afin d'amortir le son mesuré. Un contrôleur de son est raccordé de manière fonctionnelle au dispositif d'amortissement acoustique et est configuré de façon à recevoir automatiquement un signal d'environnement en provenance d'un capteur d'environnement. Le contrôleur de son est configuré pour déterminer un mode de fonctionnement du véhicule sur la base du signal d'environnement. Le mode de fonctionnement peut être choisi à partir d'une liste de modes de fonctionnement qui inclut un mode de fonctionnement sous contrainte et un mode de fonctionnement calme. Le contrôleur de son est configuré pour provoquer l'altération du signal de suppression de bruit et la réduction de l'amortissement en mode de fonctionnement sous contrainte relativement au mode de fonctionnement calme.
