1. A self-adjusting implantable cochlear stimulator (ICS) system comprising cochlea stimulus means for selectively generating a stimulus of a specified intensity on any one of a plurality of channels and evoked potential sensing means for sensing an evoked potential in response to a stimulus generated by the stimulus means, comprising: middle ear reflex sensing means for sensing a middle ear reflex in response to a stimulus applied by the stimulus means; and microcontroller means for controlling the cochlea stimulus means, evoked potential sensing means and middle ear reflex sensing means to determine the stimulation threshold and most comfortable loudness of the ICS.
