Adult recipients of cochlear implants (CI) generally loose interest in listening to music.
This may be due to the rather limited spectral resolution of CI. However, child
CI-recipients, if offered the opportunity, like to listen to music. They participate
actively in musical acitivities, such as singing, dancing or playing an instrument. Thus,
there seems to be a fundamental difference in the music perception of people who receive CI
as child or as adult.
This study assesses music perception skills of child, teen and adult cochlear implant
recipients in settings with simple tone sequences and in a more complex, melodious context.

| Type | Measure | Description | Time frame | Safety issue |
|---|---|---|---|---|
| Other | How can the findings of the primary and the secondary outcome measure be used to improve music perception with existing cochlear implants? | Can the results of the primary and the secondary outcome measure be applied to improve music perception with existing cochlear implants - e.g. by changing / adapting algorithms? | 6 months | No |
| Primary | Does the age at which a person receives a cochlear implant influence music perception skills? | The test assesses wether cochlear implant carriers are able to hear the difference betweent two sequences of sounds, where in the second sequence on tone is different from the first sequence. If a difference is perceived, then the test assesses how big this difference has to be in order to be heard. The first and the second test are no more than six months apart; both times the same procedure is followed. The test is carried out with three age groups: Children aged 3-10 years Teenagers aged 11 - 14 years Persons above 15 years |
Test and retest are taken within 6 months | No |
| Secondary | Do the results of the primary outcome measure depend on the tone sequence presented to the cochlear implant recipients? | The test is carried out with three different tone sequences: Same tone at three different octaves (control tune: 131 Hz, 262 Hz, 523 Hz) Tune of rising, then falling notes Tune of rising notes only |
Test and retest are no more than 6 months apart | No |
