The purpose of this study is to evaluate audio quality benefit for the patient implanted with a Cochlear or Otologics Carina implant with the new firmware (feedback canceller algorithm) whatever the patient environment is and to evaluate the functional gain and speech understanding benefit for the patient upon the firmware used (new and reference firmware). The new firmware aims to adapt automatically for feedback cancellation without prior calibration.
