受检者生理特性能影响听觉脑干反应(ABR)潜伏期和波幅。成年女性 ABR 潜伏期短于成年男性,虽然有些研究者认为这种性别差异同中枢神经系统和脑体积的差异有关,但确切机制迄今不明。为探讨头颅体积与 ABR 潜伏期和波幅的关系,作者对60名正常听力(纯音测听证实)成年人(男30名,女30名,年龄17～34岁,平均24.9岁)进行头颅体积测量和 ABR 记录。研究结果表明,男性受检者头颅体积明显大于女性受检者,ABR 各波潜伏期与
The physical characteristics of subjects can affect the auditory brain stem response (ABR) latency and amplitude. The ABR latency of adult women is shorter than that of adult men. Although some researchers consider this gender difference to be related to differences in central nervous system and brain volume, the exact mechanism remains unknown so far. To investigate the relationship between head volume and ABR latency and amplitude, the authors measured cranial volume in 60 normal hearing adults (30 males, 30 females, aged 17-34 years, mean 24.9 years) ABR record. The results showed that male subjects significantly larger than the head of the female subjects, ABR wave latency and
