COCHLEAR IMPLANT APPARATUS FOR ACTIVE FEEDBACK CONTROL, AND METHOD FOR SAME

摘要

The present invention relates to a cochlear implant apparatus, and more particularly, to a cochlear implant apparatus capable of adjusting the sensitivity or selectivity of a sound by means of an actuator. According to the present invention, the cochlear implant apparatus for active feedback control, which is inserted inside the human body to sense sound for each frequency band, includes: a sensor unit sensing the vibration caused by a sound and generating an electric signal corresponding to the size of the vibration; and an actuator disposed in the sensor unit and responding to the electrical signal in order to adjust the sensitivity according to the amplitude of the sound or to adjust the selectivity of the sound sensed for each frequency band.
