COCHLEAR IMPLANT HAVING NOISE REDUCTION FUNCTION AND METHOD FOR REDUCING NOISE

摘要

The present invention receives a plurality of external sound microphone, analog sound signal to generate an analog sound signal a front end to convert a digital sound signal, a preset signal to extract the digital audio signal from the digital sound signal using a signal processing algorithm processing, generation request signal for generating a stimulus signal corresponding to the required stimulus digital audio signal and the magnetic pole portion converts the request signal to correspond to a preset communication method comprising a noise reduction device comprising a body to stimulate the auditory nerve so as to correspond to the magnetic pole request signal received from the extracorporeal device and the extracorporeal device which includes a transfer device for transferring the body relates to a cochlear implant and noise reduction methods, even in noisy environments so that the patient wears a hearing aid can be provided only the audio signal clearly.
