Extended high-frequency threshold in tinnitus patients and corresponding controls

Of the 18 patients with tinnitus, 12 (patients 1, 2, 3, 4, 6, 8, 10, 11, 12, 13, 14, and 17) had significantly increased hearing thresholds at more than one of the three tested frequencies in comparison with the age- and gender-matched normal group. In the other six patients (patients 5, 7, 9, 15, 16, and 18), the hearing threshold did not differ or was lower than that of the normal group.
