Patent ID: 7224815

Claim:
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 and electrically connected to the electronic circuitry; 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; and further wherein signal processing circuitry includes means for processing the signals sensed through the microphone so that the sound waves emitted towards the ear canal by the acoustic transducer are compatible with and augment the sound waves traveling naturally through the ear canal.
