Cochlear Implants : Influence of Microphone Aging & Dirtying

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Clinical Trial Summary

Cochlear implant microphones are subject to aging and dirtying. The evolution may affect their efficiency. Several signal coding strategies are used in cochlear implants and their behaviour may be more or less affected by the aging process. In this work the investigators wish to assess this phenomenon.
