An observational study in Cochlear Implant Recipients, sponsored by University of Zurich. Completed at 1 site in Switzerland. Open to participants aged 3 Years to 70 Years. Per ClinicalTrials.gov, last updated 2013-06-12.
Sponsored by University of Zurich · Observational
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.
University of Zurich is the lead sponsor of 1,030 studies on the registry; 130 are open to participants now.
Counted across the registry records on this site, refreshed daily.
Healthy CI recipients that receive their regular follow-ups in the ENT-clinic of the Zurich University Hospital.
Exclusion criteria:
Assessment of music perception skills with cochlear implant recipients aged 3 - 10 years
Behavioral: Assessment of music perception skills
Assessment of music perception skills with cochlear implant recipients aged 11 - 15 years
Behavioral: Assessment of music perception skills
Assessment of music perception skills with cochlear implant recipients aged 16 - 70 years
Behavioral: Assessment of music perception skills
A sequence of tones is presented to participants. Then the same sequence is presented again, with the 4th tone being one to six half tones different from the first sequence. Participants are asked to indicate when they hear a difference betweent the first and the second sequence.
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: 1. Children aged 3-10 years 2. Teenagers aged 11 - 14 years 3. Persons above 15 years
Time frame: Test and retest are taken within 6 months
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: 1. Same tone at three different octaves (control tune: 131 Hz, 262 Hz, 523 Hz) 2. Tune of rising, then falling notes 3. Tune of rising notes only
Time frame: Test and retest are no more than 6 months apart
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?
Time frame: 6 months
