Abstract

L'invention concerne des casques à réduction active du bruit (ANR) protégeant l'audition de leurs utilisateurs des bruits persistants intenses, tels que ceux générés par des moteurs d'avions et des engins de chantier. Ces casques comprennent généralement des écouteurs et des circuits spéciaux destinés à effacer ou à supprimer certains types de bruits persistants intenses. Un problème que l'inventeur a constaté avec ces casques actifs, notamment ceux fabriqués en grande quantité, concerne les variations de performance émanant de variations inévitables dans le logement des protège-oreilles contre la tête de leurs utilisateurs. Par exemple, en mettant ou en enlevant ces casques, certains utilisateurs font face à des bruits graves. En conséquence, l'inventeur a conçu, parmi d'autres choses, des casques comprenant des aérations avant sous forme de cavité destinées à équilibrer la pression entre une partie de cavité avant d'un protège-oreilles et un environnement ambiant.
