Abstract

Transmetteur insonorisé pour la suppression active des champs acoustiques indésirables au moyen d'interférence commandée sous la forme d'un système de régulation constitué par un capteur acoustique et une source sonore, par exemple un haut-parleur, qui est commandé par le capteur de façon que dans les zones des champs acoustiques il règne une constance de pression signifiant l'absence de bruit. Le capteur 4 et la source sonore 5 sont réalisés sous la forme d'une unité intégrée
