Abstract

La présente invention concerne un dispositif de bouchon d'oreille (10) qui est placé dans le conduit auditif (20) pour atténuer des fréquences sonores dans une plage de fréquences sélectionnée. Le dispositif de bouchon d'oreille (10) comprend un corps de bouchon (12) pourvu d'une première extrémité (14), d'une seconde extrémité (16) et d'une surface extérieure (18) qui s'étend de la première extrémité (14) à la seconde extrémité (16). Un canal d'évent étroit (25) est formé dans la surface extérieure (18) du corps de bouchon pour égaliser une pression d'air par le passage d'un petit volume d'air à travers le dispositif de bouchon d'oreille (10) vers le canal auditif (20).
