title: The comparison of acoustic and psychic parameters of subjective tinnitus.
abstract: We aim to assess the correlation between audiometric data, and psychotic and acoustic measures associated with subjective tinnitus (ST) and to clarify the importance of the psychological process in determining the degree of subjective annoyance and disability due to tinnitus. Fifty-four patients experiencing unilateral ST were allocated for the study. Acoustic assessment of patients including LDL (loudness discomfort levels), MML (minimum masking level) and RI (residual inhibition) was performed. Tinnitus Handicap Inventory (THI), Beck Depression Inventory (BDI) and Visual Analog Scale (VAS) tests were performed for the psychological aspects of subjective annoyance. RI was positive in 23 patients with 13 frequency-matched stimuli at 8,000 Hz. Masking treatment response was successful in 16 RI-positive patients. Mean and standard deviation (SD) of THI scores were 38.77 ± 23.63. Ten patients (%18.51) with tinnitus had ≥ 17 points score, which was significant for BDI. Mean and SD were 5.01 ± 2.31 for VAS-1 scores (severity of tinnitus), 7.98 ± 2.79 for VAS-2 (frequency and duration of tinnitus), 5.77 ± 2.72 for VAS-3 (discomfort level), 3.56 ± 3.30 for VAS-4 (attention deficit) and 3.31 ± 3.31 for VAS-5 (sleep disorders). A significant correlation was found between the tinnitus duration time, age, gender and THI scores (P < 0.05). There were statistically significant correlations between VAS 1, 2, 3 scores and LDL, MML and RI (P > 0.05). RI might be largely frequency dependent and was found as an indicator for the masking treatment response. We did not notice statistically significant correlations between audiometric data and THI and BDI. There were correlations between with VAS and LDL and with MML and RI. VAS was simpler and easier for the assessment of ST. We should consider the psychological aspects of ST and assess it as a symptom separately with acoustic and psychotic tests.
