Outcome measures
Primary outcome
Speech intelligibility test results with optimized MAP parameters, compared to
the speech test intelligibility results with standard MAP parameters.
Secondary outcome
not applicable.
Background summary
In a previous study by de Graaff et al. (2019)(NL.51919.029.15) several fitting
parameters were identified that may improve speech recognition in quiet and
speech recognition in noise in adult cochlear implant (CI) users. The results
suggest that optimizing these parameters in CI users with a non-optimal fitting
could result in improved speech recognition.
Study objective
The aim of the current study is to examine whether it is possible to improve
speech recognition in specific CI users by optimizing dynamic range and mean
aided thresholds. Furthermore, we want to investigate to what extent patient
counselling and acclimatization can help in accepting these optimal CI settings
by the CI user.
Study design
Single-center experimental study.
Intervention
not applicable.
Study burden and risks
Compared to care as usual, participants will have to pay two additional visits
to the department of audiology for extra speech recognition tests or extra
fitting sessions. Immediate benefits for individual subjects are to be expected
from participation in this study. Furthermore, the knowledge on the technical
innovations for fitting and rehabilitation of cochlear implant users is
expected to contribute to the improvement of the therapy for cochlear implant
users.
