[Tinnitus and expert opinion (author's transl)].

For giving an expert opinion on subjective tinnitus one should try to define it as for its frequency-character, loudness and the masking by white noise. Tinnitus with chronic hearing impairment due to noise should be rated with an additional disability to work of 5%. At ear noise caused centrally or cervically a disability to work of 10% can be justified--as far as those complaints are to be valued.
