ABSTRACT:
An electronic hearing aid device for enabling persons having loss of hearing due to a nonfunctioning inner ear (Cochlea), but have a responsive auditory (acoustic, or eighth cranial) nerve, to hear by way of an electronic device including a microphone for receiving audio signals connected to an amplifier for converting the audio signal into an analog voltage signal. The analog voltage signal is filtered by a series of filter networks which separate the analog voltage signal into a plurality of frequency component signals each having a predetermined frequency range within the audio spectrum. The component analog voltage signals are then converted into digital pulse signals having the same frequency as the component voltage signal which are fed to the auditory nerve by way of implanted platinium (or other) wires wherein the digital pulse signals more accurately simulate the natural sound signals transmitted to the brain for interpretation.
