Outcome measures
Primary outcome
Speech perception scores after recipients tried to optimize their own maps in combination with subjective questionnaire and log of button presses.
Secondary outcome
N/A
Background summary
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.
Study objective
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.
Study design
N/A
Intervention
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.
