Abstract:
ObjectiveTo search for the optimum external masking time and tonal models for patients with tinnitus.MethodsTwenty-seven patients with cochlear tinnitus were selected respectively from three different out-patients departments and divided into three groups. Nine patients in every group were treated with different masking parameters according to factorial design which had three masking noises, i.e. narrow band noise (NBN), wide band noise (WBN), speech noise (SN),and three masking time ranges, i.e. 15,30,45 minutes. The results before and after treatment were compared and analysed with analysis of variance (ANOVA). ResultsThe treatment effect when masking for 15 minutes was worse than that for 30,45 minutes, but there was no difference between 30 and 45 minutes. The NBN had the best effect when tinnitus signal was single, the WBN was effective for tinnitus with multiple sounds. ConclusionNBN or WBN masking for 30 minutes showed better therapeutic effect.
