[Psychoacoustic and clinical features of patients with idiopathic tinnitus].

Objective: The aim of this study is to explore the psychoacoustic and clinical features of patients with idiopathic tinnitus, to understand the relationship and regularity between tinnitus frequency, loudness and hearing loss, and to provide a basis for personalized diagnosis and treatment of tinnitus. Method: A total of 110 patients with idiopathic tinnitus underwent systematic otological professional examination,audiological examination, tinnitus refinement examination, medical history inquiry and tinnitus disability scale(THI) survey. Result: Tinnitus more frequently occurred between 20 to 60 years of age(95.45%),a significant decrease in people under the age of 20 and over the age of 60;67 cases(60.9%) of the tinnitus frequency were completely consistent with the maximum frequency of hearing loss, The Pearson test showed that tinnitus frequency was correlated to frequency of hearing loss (r=0.989, P <0.05).Tinnitus loudness pitch results are mostly concentrated between 40-60dBSL, The Pearson test showed that tinnitus loudness was correlated to hearing loss(r=0.932, P <0.05);The total effective rate of sound therapy was 67.3%,There was a correlation between Residual inhibition and sound therapy(r=0.438, P <0.05); No statistic difference was found between THI scores and Tinnitus duration (r=-0.047, P >0.05). Conclusion: There was a correlation between tinnitus pitch and hearing loss.Residual inhibition may indicate the effectiveness of the sound therapy and may affect the patient's THI score. Full Precision Test can provide clinical reference for early detection of hearing loss in tinnitus patients.
