Comparison of Speech Understanding Between Tonotopy-based Fitting and Setting Based on Evolutionary Algorithms

Condition(s) studied

Investigational drug(s) / intervention(s)

EAFS4T: modification with evolutionary algorithm of tonotopic-based fitting: Comparison of FS4T and EAFS4T

Study summary

Main objective:

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

Eligibility

Primary outcome measure(s)

• Speech recognition in noise — 6 weeks after EAFS4T fitting
  HINT-5 min test. Noise level: 60 dB SPL. Speech level: adaptive with the answers of the participant. Result: speech-to-noise ratio (speech reception threshold, SRT50) for 50% of intelligibility in noise. Test with EAFS4T and with FS4T.
