Speech understanding with a speech processor fitted using the parametric fitting procedure and the recipient's own fine-tuning is as good as with a conventional fitting. The parametric fitting is more patient friendly and less time-consuming.

Uitkomstmaten
Primaire uitkomstmaten
Speech perception scores after recipients tried to optimize their own maps in combination with subjective questionnaire and log of button presses.
Achtergrond van het onderzoek
In 20 adult cochlear implant recipients we measure speech perfomance using the parametric fitting procedure and the recipient's own adjustment in a newly designed speech processor and compare it with the parametric fitting without adjustments.
Doel van het onderzoek
Speech understanding with a speech processor fitted using the parametric fitting procedure and the recipient's own fine-tuning is as good as with a conventional fitting. The parametric fitting is more patient friendly and less time-consuming.

Onderzoeksproduct en/of interventie
Temporary use of a newly designed speech processor. Twenty cochlear implant patients receive an experimental speech processor, with which they can manually adjust the parameters 'shift' and 'tilt' of the C levels.
For the first 3 weeks they get an ECAP-based fitting in the new processor, without the possibility to make adjustments.
Speech perception tests are performed with the conventional and the ECAP-based fitting.
The last 3 weeks patients can adjust their fitting. This period is followed by speech perception tests with the non-adjusted and the adjusted ECAP-based fitting.
