Inclusion criteria

Inclusion criteria: - Legally capable. - Fluent in Dutch, preferably being their native language. - Aged 18 or older. - Implanted with an Advanced Bionics HiRes90K 1J, HiRes90K MS or CII+ positioner Cochlear Implant. - At least 6 months of experience with their CI. - Has read the protocol, willing to participate and have signed informed consent. - Agree that their data is analysed and are presented pseudonimized, together with the data of other participants.

Exclusion criteria

Exclusion criteria: - Too high impedance variations across electrode contacts. - Disorders other than a hearing impairment that could affect the study results, such as psychiatric disorders or physical disorders that would limit their ability to undergo testing (e.g. depression).

Design outcomes

Primary

MeasureTime frame
Distinguishable inter-contact distances (ICD; e.g. channel discrimination) as determined by two separate tests. We are interested in the correlation between the found ICDs in both tests. Also, we want to improve the first version of the software, leading to more user-friendliness.

Secondary

MeasureTime frame
Relate the results from both methods to position in the cochlea and consonant-vowel-consonant (CVC) scores, and possibly to patient demographics (e.g. time since implantation, age). We also want to compare the results of this study to the group we included earlier, to see if the results are similar and the algorithm is performing as expected.
