Eligibility

Inclusion criteria

Inclusion criteria: The main inclusion criterion of the tinnitus group is pure tone-, unilateral-, chronic- and subjective tinnitus which is longer present than 6 months. Age ≥ 18 years.

Exclusion criteria

Exclusion criteria: Exclusion criteria are: Fletcher Index > 50 dB HL for both ears, difference in average hearing threshold of more than 10 dB between left and right ear, hyperacusis, phonophobia, misophonia, neurological-, neurosurgical- and psychiatric history, use of dopaminergic drugs since this medication greatly influence the fMRI scans, current treatment of tinnitus and implanted devices or other metal objects that are not suitable for MRI.
