Eligibility

Age
18 Years to 99 Years

Inclusion criteria

Inclusion criteria: * Healthy * Aged 18 or older and mentally competent * Unilateral CI wearers with a CII or HiRes family implant manufactured by Advanced Bionics. * Native Dutch speaker * Written informed consent

Exclusion criteria

Exclusion criteria: * Disability which could interfere with the completion of the tests (e.g., psychiatric problems). * For the EEG measurement: a subject with very thick hair or a skin condition on the skull which makes the skin extremely sensitive.

Design outcomes

Primary

MeasureTime frame
The primary study parameters are the differences in response between pairs of CI electrodes. The response in case of the EEG measurement (passive task) is the neural power at frequencies of interest, determined by the two stimulation patterns of the two CI electrodes. For the reaction-time method (active task), the response is the manual response-reaction-time to a perceived change in the sound.

Secondary

MeasureTime frame
The secondary study parameter is the correlation between outcomes of the speech and spectro-temporal modulation tests as determined with the App and with the standard lab test methods. Further study parameters are the electrode impedances and eCAPs.
