摘要
The present invention relates to an improved acoustic prosthesis (1) having a direct action of medium ear, comprising a tubular shaped conveyor (12), canalising acoustic waves; at least a microphone picking up surrounding sounds; and amplifier, electrically connected with said microphone for amplifying picked up sounds at a suitable level; at least an audio transducer connected with said amplifier and said conveyor (12), said transducer transforming electric signals arriving from said acoustic wave amplifier, said acoustic waves being conveyed in said conveyor (12); and supply means for said amplifier and for said microphone; said acoustic prosthesis (1) being characterised in that said conveyor (12) comprises a main portion (12'), one end (12'a) of which can be placed within the medium ear (4) while its other end (12'b) can be placed within the outer ear (3) channel; and at least one more portion (12'', 12''') that can be coupled at the end of said main portion (12') and at said at least an audio transducer. The invention further relates to a process for installing an acoustic prosthesis.
