ABSTRACT:
An electronic hearing aid device for enabling persons having loss of hearing due to a [nonfunctioning] malfunctioning inner ear (Cochlea), but [have] having 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] platinum (or other) wires, wherein the [digital] pulse signals more accurately simulate the natural sound signals transmitted to the brain for interpretation.
