| Scientific title | |
| Study objectives | This study examines the effect of the Phase Out treatment on chronic, incurable tinnitus in adult subjects in comparison with placebo sound. The expectation of this study is that Phase Out treatment is effective for a longer duration and results in increased residual inhibition than placebo sound. |
| Ethics approval(s) | Ethics approval received from the Medical Ethical Committee of Groningen on the 26th June 2007 (ref: METc2007/061). |
| Health condition(s) or problem(s) studied | Tinnitus |
| Intervention | A subject will receive Phase Out treatment for thirty minutes three times a week for one week and placebo sound treatment on the same regime during another. One month interval is in between these two sets of treatment. If a treatment is started, the subject fills in a report mark on the tinnitus loudness and tinnitus annoyance in the tinnitus diary every evening till three weeks after the treatment session. One week after each week of therapy a subject receives the evaluating questionnaires and will send them back after filling in. |
