1. A cochlear implant having a speech processor configured to convert a received electrical signal representing received ambient
sound into instructions defining stimulation signals to deliver an excitation pattern to a recipient's auditory nerve, the
cochlear implant comprising:
a modeler configured to calculate a model of an excitation pattern currently existing on the auditory nerve;
an increment generator configured to determine a difference between an ideal excitation pattern representing the received
ambient sound and said existing excitation pattern in order to generate an incremental excitation pattern; and
apparatus for generating stimulation signals for delivery to the auditory nerve based on said incremental excitation pattern.
