Abstract

Cette protection auditive variable possède un mécanisme de réglage (3) qui permet de modifier l'atténuation du bruit dans un conduit (2) s'étendant à travers la protection auditive. A cet effet, un disque (16) est disposé dans le mécanisme de réglage, disque qui s'étend sur toute la section du conduit et présente des secteurs d'épaisseurs différentes. Le disque (16) est rotatif par rapport à un premier élément barrière (13) dans lequel est disposée une ouverture (15). Selon le secteur qui est amené en coïncidence avec l'ouverture (15), on peut régler une atténuation du bruit plus ou moins forte. Comme le disque (16) couvre toute la section du conduit (2), on empêche le passage des impuretés et on évite de brusques variations de pression indésirables.
