Abstract
A hearing aid module is shaped for insertion into a tunnel made through the soft tissue that connects the retro-auricular space with the ear canal. The hearing aid module contains a speaker or auditory transducer, a battery or other power source powering the module, signal processing circuitry, and a microphone. Telemetry circuitry within the module allows the signal processing circuitry to be programmed with a desired frequency response or signal processing strategy using an external programming unit. A remote control unit permits the user to make simple adjustments, such as volume and/or tone (frequency) control.
