Brainstem evoked response audiometry has been performed in 164 patients complaining of tinnitus, unilateral or bilateral. The latency of every wave and the latency between the peak of every wave have been compared with those obtained in a normal population (n = 57). The latency of the first wave is increased significantly at the same side of the tinnitus. But I-V latency is shorter at the side of the tinnitus. When this increase is absent, the I-V latency is prolonged the side of the tinnitus. It is possible to differentiate between tinnitus of peripheral origin and that of central origin, although the existence of unilateral deafness is constant. The same results have been obtained in the deaf patients with bilateral symmetric deafness, in accordance with Maurizi et al., 1985.
对164例单侧或双侧耳鸣患者进行了脑干诱发电位听力测定。将每个波的潜伏期以及每个波峰之间的潜伏期与正常人群（n = 57）的结果进行了比较。耳鸣同侧的第一波潜伏期显著增加。但耳鸣侧的I-V潜伏期较短。当不存在这种增加时，耳鸣侧的I-V潜伏期延长。尽管单侧耳聋持续存在，但仍有可能区分外周性耳鸣和中枢性耳鸣。根据Maurizi等人1985年的研究，双侧对称性耳聋的聋患者也得到了相同的结果。
