Psychoacoustic characteristics of tinnitus in sudden deafness patients

Objective:To explore tinnitus psychoacoustical detection significance in the patients with sudden deafness.To explore the relationship of the tinnitus patients with subjective grading between hearing loss.Methods:All 42 cases of sudden deafness patients test were studied.Tinnitus pitch-matching,loudness-matching,minimum masking level(MML)and residual inhibition tests were performed on the patients.Results:Firstly,tinnitus tones matching type:pure and narrowband noise are most.T Tinnitus pitch—matching and hearing loss of maximum frequency consistency have a high-pitched tinnitus.Tinnitus matching loudness is a little.Tinnitus masking curve types :overlap type and gathering type are most.Residual inhibit test :artial inhibitio are most.Secondly,tinnitus subjective classification and correlation between degree of hearing loss.Conclusion:Psychoacoustic techniques can produce a useful amount of clinical data regarding tinnitus in different aspects,for tinnitus treatment provides detailed clinical data.Tinnitus patients produced psychological impact with hearing loss degree increased heavier.
