Abstract:
A hearing aid adapted for insertion into a tunnel that connects a retro-auricular space to an ear canal, comprising:a hearing aid module comprising: a case; electronic circuitry housed in said case; an acoustic transducer electrically connected to said electronic circuitry; a microphone also electrically connected to said electronic circuitry; and a power source housed in said case end electrically connected to the electronic circuitry; a hollow tube adapted for insertion into the tunnel, wherein the case of the hearing aid module is adapted to be slidably inserted into and withdrawn from said tube; wherein the electronic circuitry includes signal processing circuitry for amplifying and processing signals sensed through the microphone and for presenting the amplified and processed signals to the acoustic transducer; and wherein the acoustic transducer converts the amplified and processed signals received from the electronic circuitry to sound waves, which sound waves are emitted towards the ear canal.
