Evaluation of New Feedback Canceller for Carina™ Implant

October 6, 2017 updated by: Cochlear

Evaluation of a New Feedback Canceller Algorithm for Patient With Moderate to Severe Hearing Loss Implanted With a Fully Implantable Carina™ Medical Device

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.
