timbre perception in cochlear implant users
Conditions
Interventions
Group 1: Adult cochlear implant users with implants from Med-EL, undergo electro-physiological and psychometric measurements of timbre dicrimination skills with 2 different programming maps (with and

Inclusion criteria
Inclusion criteria: For CI users: • Uni- or bilateral CI treatment with an implant from MED-EL • CI treatment for 6 months or longer • Daily use of the CI for at least 4 hours • Availability of an MRI or CT scan with a maximum layer thickness of 0.6 mm taken at some point prior to CI surgery • Availability of a CT or DVT scan with a maximum layer thickness of 0.6 mm taken at some point after CI surgery
Exclusion criteria
Exclusion criteria: General exclusion criteria: • Failure to meet the inclusion criteria • Lack of capacity to give consent or refusal to participate in the study • Known pre-existing conditions that affect cognition, such as dementia, depression, post-stroke condition, etc. • Use of psychoactive medications or substances • Intensive musical training (according to Hahne et al. (2016): duration of musical training >10 years, >3 times weekly practice within the last 3 years) Additional exclusion criteria for CI users: • Prelingual deafness • Lack of auditory impression when using CI • Usage of electrical-acoustic stimulation (CI with ipsilateral hearing aid) • Known misplacement of the CI electrode • Known pre-existing inner ear conditions such as cochlear malformation, otosclerosis, inner ear schwannoma • Regular use of musical training apps developed for CI users, e.g. MELUDIA
