掩蔽指数
- CONCLUSION: Tinnitus masking therapy can convert the abnormal ABR wave amplitude in patients with tinnitus to normal, which will be taken as the objective index in judging whether it is positive in residual inhibition test.
结论：耳鸣掩蔽能使耳鸣患者异常的脑干听觉诱发电位波幅恢复至正常，此结果有望作为后效抑制阳性判定的客观指标。 - The paper presents the principle of hearing testing technology, such as air conduction test, bone conduction test, masking technology, double ear sonorous blance, short increment sensitivity index, and the audiometer as hearing testing tool.
