Abstract
Abstract A device is designed to provide persons with a mild, moderate, severe or profound hearing loss the ability to hear sound that would be inaudible, as well as the ability to hear ambient environmental noise. The device is fabricated as: (1) a receiver assembly having a pliable flexible strip worn in the outer ear with a small transducer which extends into the auditory canal, and (2) a transmitter assembly having a microphone located remotely on the person whereby information is transmitted to the receiver assembly via modulated carrier waves. The need for a battery in the receiver assembly is eliminated as the power supply is driven by magnetic induction from the transmitter assembly positioned a few inches away, as in a neck pendant.
