In this research, psychofysical tests will be used to explore in which way the signal processing in CI and hearing aid can be optimized to fully exploit both input modalities in speech understanding, and in sound localization..

Background summary
Users of a cochlear implant increasingly have residual hearing and wear a
conventional hearing aid in the non-implanted ear. Often, the acoustical and
electrical input are complimentary, but in some patients a conflict arises and
the hearing aid is abandoned. The reason for this conflict is unknown.
Study objective
In this research, psychofysical tests will be used to explore in which way the
signal processing in CI and hearing aid can be optimized to fully exploit both
input modalities in speech understanding, and in sound localization..
Study design
Interventional within subject cross-over design
Intervention
Fitting of a hearing aid.
Study burden and risks
Visits to the research facility, auditory tests for about 2 hours per visit,
questionnaires.
Acclimitization to a new hearing aid: (temporary) drop of sound quality, speech
understanding, orientation in the environment - note that subjects still have
their old hearing aid, if needed.
