f

denotes female. Hearing thresholds reported in dB 1969 ANSI. All patients had down sloping sensory neural hearing loss from a mild level to the maximum loss indicated. B=bilateral, R=right, L=left, M=maximum hearing loss, & K= frequency in Hz. Tinnitus duration is reported in years. THQ = Tinnitus Handicap Questionnaire total score; TSI=Tinnitus Severity Index; BDI=Beck Depression Inventory. Studies column indicates the pilot studies, 1–3, in which each subject participated.
