Abstract:
[Objective] To evaluate the efficacy of sound therapy and provide a kind of treatment for tinnitus patients with normal audiogram.[Methods] From the database of the Audiometric Center of the First Affiliated Hospital,Sun Yat-sen University,we identified 46 outpatients with normal hearing thresholds in the conventional pure-tone audiometry suffering subjective tinnitus over 3 months.The clinical information were collected with respect of age,gender,tinnitus severity,pitch,laterality and duration,comorbid symptoms.All the patients received the tinnitus test,including loudness and frequency of the tinnitus and residual inhibition,Tinnitus Handicap Inventory (THI) and Visual Analogue Scale (VAS) scores pre-and post-complex sound therapy.The complex sound were remixed with natural sounds and music materials,while the masking frequency of natural sounds is consistent with the tinnitus frequency of patients and the main frequency of music materials covers the tinnitus frequency.[Results] 32 of the 46 patients showed residual inhibition (RI) positive.The average THI score before treatment was 33.38±16.23 and the VAS score was 4.38±1.62.The THI score decreased to 21.75±11.67 and the VAS score was 2.97±1.06 after sound therapy.The rest 14 patients were residual inhibition (RI) negative.The THI score were 29.86±20.15 and 23.43±16.29 pre-and post-complex sound therapy,while the VAS score were 3.93±1.69 and 3.36±1.2.The THI and VAS scores were significantly decreased after the treatment in both RI positive and negative patients.The RI positive group showed better results than RI negative group.[Conclusions] Both RI positive and negative tinnitus with normal audiometry shown adaptation with complex sound therapy,RI positive patients acquired more benefits from tailor-made complex sound therapy.
