Abstract
A hearing aid has a sound-conducting tube, the distal end of which extends into the auditory meatus. The tube is mounted to an earpiece which closes off the ear canal. A protrusion surrounds the distal end and extends from the earpiece. A cap is detachably secured to the protrusion and is perforated to permit sound to travel into the ear, and the cap and the earpiece form a cerumen-trapping gap. The earpiece of the hearing aid has a substantially flat end plate adjacent the protrusion and the end plate bears a groove which surrounds the protrusion.
