Abstract

Le dispositif d'atténuation acoustique active d'un signal acoustique se propageant dans un conduit comprend: au moins des premiers moyens capteurs (2) d'un premier signal acoustique, des moyens actionneurs d'atténuation (6) délivrant un signal d'atténuation acoustique active en réponse à un signal de commande choisi, et des moyens électroniques de commande générant le signal d'atténuation acoustique active pour les moyens actionneurs. Les premiers moyens capteurs (2) et les moyens actionneurs (6) sont disposés en totalité à l'intérieur du conduit, en regard les uns des autres, et à une distance choisie de la gaine du conduit, l'axe de symétrie du rayonnement des moyens actionneurs et l'axe de symétrie des premiers moyens capteurs (2) sont sensiblement parallèles à la direction de propagation du signal acoustique dans le conduit, et les moyens actionneurs (6) sont disposés en amont des premiers moyens capteurs (2) selon le sens de propagation du signal acoustique dans le conduit.
