Abstract

A hearing aid is disclosed in which the outside sound collected by a microphone is amplified and radiated from the earphone unit so as to be conducted to the user's external auditory meatus. The auditory tube is of an inside diameter approximately equal to that of the user's external auditory meatus and has one end arranged as a section for attachment to the user's auricle and the other end arranged as a reflectionless terminal. The earphone unit is mounted on the peripheral surface of the auditory tube with the sound radiating surface facing the inside of the tube.
