听性脑干诱发电位（ABR），早已用于临床以早期发现和诊断听觉障碍。在成人，经鼓解电刺激的心理行为阈值的测定是指示耳蜗植入术后电兴奋性的优良指标。在许多10岁或Ic岁以上的儿童中，可通过行为测试得到精确的、恒定的鼓螂刺激阈值，但在3～6岁儿童，这项工作则十分困难。经 Auditory brainstem response (ABR), has long been used clinically to detect and diagnose early hearing impairment. In adults, the behavioral threshold of psychological behavior stimulated by stimulation is an excellent indicator of electrical excitability after cochlear implantation. In many children 10 years of age or over Ic, accurate, constant drumming stimulus thresholds can be obtained through behavioral testing, but this can be difficult for children aged 3-6 years. through
