Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Pilot study on safety, tolerability and clinical performance/randomized double-blind active-controlled pilot-study. Patients are being recruited from patients of the Tinnitus Center of Regensburg and groupwise randomized. Control groups are being treated with hearing aids without notch-filter. Patients and raters are blinded, only the coworker, who is programming the hearing aids, is informed about the group assigned.

A Hearing aid with notched amplification filters frequencies in a specific manner, depending on the individual tinnitus frequency. Through this special filtering the neuronal functional changes of the auditory cortex are supposed to be affected therapeutically.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria
