An Implantable Cochlear Stimulation (ICS) system includes a single electrode array partitioned into two subsets of electrodes to provide binaural hearing. The ICS system receives sound from at least two microphones. One of microphones provides a first signal dominated by sound arriving from the user’s left, and another microphone provides a second signal dominated by sound arriving from the user’s right. The first and second signals are processed independently and provided to the two subsets of the electrodes of the single electrode array implanted in one of the user’s cochlea. The human higher level neural processes are able to distinguish between signals with different characteristics, thus enabling the user to distinguish between the signals originating in the right microphone versus the left microphone, thereby providing binaural hearing.
