Technology Description

Researchers at the University of Iowa have developed advancements for the cochlear implant that allow it to optimally deliver high and low frequency sounds for the patient. This hybrid cochlear implant utilizes two or more separately modulated electrodes for the transport of various frequencies. The low frequency sounds are preferentially delivered to the basilar region of the cochlea and the high frequency sounds are delivered via electrodes that terminate beyond the first basilar turn of the cochlea. This allows the two frequencies to be modulated specifically for each patient's needs, and allows for the utilization of some to total natural hearing ability in the frequencies where electronic stimulation is less needed by the patient.
