<p>A cochlear prosthesis comprising an electrode array of individually addressable electrodes and a stimulator device to provide electrical stimuli to selected groupings of electrodes in response to sound signals. The stimuli and the electrode groupings being determined by reference to a predefined instruction set. The cochlear prosthesis is characterized in that in response to different sound signals at least two distinct current distribution geometries are induced in the auditory structures of a user. This may be achieved by using different electrode geometries, different stimulation modes, combinations of stimulation modes and/or electrode geometries.</p> |
