Cochlear implant telemetry

Abstract

Artificial cochlea or cochlear implant is the name for neurosensory prosthesis, which is a current surgical treatment for severe hearing loss or deafness.The surgical procedure is cochlear implantation During the cochlear implantation one of the methods of neural response measuring of the auditory nerve to electrical stimulation is telemetry. It is an integral part of the cochlear implantation procedure. Telemetry determines audibility thresholds, stimulus discomfort thresholds, and dynamic range. With objective parameters, in telemetry we also estimate psychoacoustic parameters, which are the basis of simulation maps for the future hearing rehabilitation.
