Abstract

L'invention porte sur des moyens de protection auditive comprenant : au moins un élément recouvrant l'oreille, telle une coquille antibruit (10); un haut-parleur (12) disposé à l'intérieur de la coquille (10); un module électronique (14) soutenu à l'extérieur de la coquille (10); et des contacts (16) destinés à relier fonctionnellement le module électronique (14) au haut-parleur (12). Le fait que l'électronique soit logée dans un module (14) qui est disposé à l'extérieur de la coquille (10) signifie que le module électronique (14) et la coquille (10) sont séparés, réduisant de la sorte la nécessité d'une interconnexion physique entre eux qui pourrait nuire aux caractéristiques d'atténuation de bruit de la coquille (10). Le module (14) peut être enlevé de coquille antibruit (10) ou peut être fixé à cette dernière.
