Abstract
(EN)
A hearing aid of conventional configuration comprising a microphone at one end adapted to be placed in the inlet of the external auditory meatus, a loudspeaker at the other end adapted to be placed within the auditory meatus, and an amplifying device between the microphone and the loudspeaker, has a means (26) of sound-dampening material over the microphone to prevent that sound directly impinges upon the latter, but is provided with a passage (27) containing a sound-transmitting medium and directed towards the inner side of one of the parts of the auricle (10), preferably the tragus (14), so that only sound picked up and treated by the auricle (10) is supplied to the loudspeaker.
(FR)
Aide acoustique de configuration classique comprenant un microphone à l'une de ses extrémités, conçu pour être placé à l'entrée du conduit auditif externe, un haut-parleur à l'autre extrémité, conçu pour être placé à l'intérieur du conduit auditif, et un dispositif d'amplification entre le microphone et le haut-parleur, qui comporte un système (26) d'amortissement du son sur le microphone évitant que le son n'interfère directement sur ce dernier, tout en présentant un passage (27) renfermant un milieu de transmission du son qui est dirigé vers la partie interne de l'une des parties constitutives de l'auricule (10), de préférence le tragus (14), de sorte que seul le son capté et traité par l'auricule (10) est communiqué au haut-parleur.
