  • the number of sectors in disk 16 is four in the embodiment of FIGS. 1-5. However, only two, three or more than four sectors or areas of different thickness may be provided. The individual sectors can merge stepwise or continuously. It is also conceivable that the thickness of the disc 16 increases steplessly from a minimum thickness in the first sector to a maximum thickness in the last sector. In addition, the thickness within a sector need not be homogeneous - it is crucial that the average thickness of the at least two sectors is different. While preferred embodiments of the invention are described in the present application, it is to be understood that the invention is not limited thereto and may be embodied otherwise within the scope of the following claims.

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.
