Brainstem evoked response audiometry has been performed in 139 patients complaining of tinnitus, unilateral or bilateral. Amplitudes of I, III, V waves and the amplitude relations I/III, I/V, III/V have been compared with those obtained in a normal population (n = 20). Amplitudes of waves I and III decreased according to their localization: decrease of left I and III for left tinnitus, decrease of left I and right III for right tinnitus, and for I and III both left and right for bilateral tinnitus. Recording of brainstem evoked response before any therapeutical treatment, especially study of amplitudes, could therefore provide information an localization of tinnitus.
对139例主诉耳鸣（单侧或双侧）的患者进行了脑干听觉诱发电位检查。将I、III、V波的波幅以及I/III、I/V、III/V的波幅关系与正常人群（n = 20）的结果进行了比较。I波和III波的波幅根据其定位而降低：左侧耳鸣时左侧I波和III波降低，右侧耳鸣时左侧I波和右侧III波降低，双侧耳鸣时I波和III波双侧降低。因此，在任何治疗之前记录脑干听觉诱发电位，尤其是对波幅的研究，可以提供有关耳鸣定位的信息。
