Abstract

A disposable hearing aid insertable into an ear canal which includes a microphone which translates acoustic energy into electrical signals, signal processing circuitry which processes the electrical signals provided by the microphone, a receiver which converts the processed electrical signals into acoustic energy, and a power source permanently disposed within the hearing aid such that the source is substantially non-removeably integrated with the hearing aid.
