Abstract
A hybrid BTE and CIC hearing aid has a BTE component which is worn behind the patient's ear and a CIC component which is worn in the bony portion of the patient's ear canal. The BTE and CIC components are connected together with a wire cable. Electroacoustic feedback is reduced or eliminated, allowing gain to be increased. The patient is not disturbed by the occlusion effect.

A hearing aid, comprising:
- a behind-the-ear component, the behind-the-ear component being shaped to fit behind the ear of a patient and containing a microphone, battery receiving means and amplifier means, the amplifier means being operatively connected to the microphone and a battery received in the battery receiving means, and producing an amplified electrical signal in response to sound at the microphone;
- and
- a completely-in-canal component, the completely-in-canal component being mechanically isolated from the behind-the-ear component, being shaped to fit into the ear canal of the patient in such a manner as to touch the bony portion of the ear canal, the completely-in-canal component containing a hearing aid receiver and being operatively connected to the amplifier means.
