对 15 名患有由肿瘤、出血、脑炎和退行性疾病引起的第八神经或脑干疾病的患者进行了无意义的单音节听力测试。所有患者的听觉脑干反应（ABR）均异常。 ABR 异常的定义是部分或全部波缺失或 V-I 波间隔延长。在完全不存在 ABR、部分 ABR 系列涉及波 I 或波 V-I 间隔严重延长（超过 3 个 SD）的患者中，无义单音节的辨别分数显着较低。然而，在仅具有 I 波或仅具有适度延长的 V-I 波间隔（小于 3 SD）的患者中，测试分数在正常范围内。结论是： 1. 脑干病变患者对无意义单音节词的感知可能（但不一定）受到影响； 2. 第八神经损伤严重扰乱听觉理解以及无意义单音节的感知。
A nonsense monosyllable audiometric test was administered to 15 patients with eighth nerve or brain stem disorders caused by tumor, hemorrhage, encephalitis, and degenerative disease. Auditory brain stem responses (ABR) were abnormal in all patients. ABR abnormalities were defined by the absence of some or all waves or by a prolongation of the wave V‐I interval. The discrimination scores of the nonsense monosyllables were significantly lower in patients with completely absent ABR, with partial ABR series involving wave I, or with severely prolonged wave V‐I intervals (over 3 SD). However, in patients with wave I only or with only moderately prolonged wave V‐I intervals (less than 3 SD), test scores were within normal range. It is concluded that: 1. perception of nonsense monosyllables could be, though need not be, affected in patients with brain stem lesions; 2. eighth nerve lesions severely disrupt auditory comprehension as well as perception of nonsense monosyllables.
