About the trial

What the trial wants to find out

Main objective:

Read full original descriptionShow less

Compare speech recognition in noise with tonotopic setting (FS4T) and with tonotopic fitting modified by evolutionary algorithm (EAFS4T) in adult patients implanted for 6 months or more with a MED-EL cochlear implant with FS4T.

Secondary objectives:

Comparison of FS4T and EAFS4T settings

* for speech recognition in quiet * for subjective auditory spatial perception * for subjective auditory and musical perception

The group in the trial

  • EA armOther group

    at 6 month post-activation: evolutionary algorithms to modify the tonotopy-based fitting FS4T to give EAFS4T fitting. Participant wears EAFS4T during 6 weeks.

    Treatment: EAFS4T: modification with evolutionary algorithm of tonotopic-based fitting

Questions to ask the study team

  1. How often do I need to come in, and for how long each time?
  2. Are travel costs paid?
  3. Can I keep my own doctor?
  4. What happens if I want to stop?
