Claim 11:
12. The system of claim 1, wherein:
the determining of the proximity of the electrode lead to the cochlear tissue is performed based on a difference between:
the energy magnitude of the field detected by the third electrode to reflect from the cochlear tissue located within the field, and
a baseline energy magnitude of the field that is representative of an energy magnitude of the field in an absence of reflections of the field from cochlear tissue within a predetermined proximity of the third electrode; and

the determining of the proximity of the electrode lead to the cochlear tissue includes determining an electrode lead approach status within the cochlea and with respect to a modiolus of the cochlea based on a determination that the difference is greater than at least one predetermined energy magnitude threshold.
