听性脑干反应(auditory brainstem response,ABR)检测是临床常用的一种听觉诱发电位检查手段,除用作听神经通路的诊断性检查外,还可用于客观听阈的评估。ABR是一种瞬态反应,只有大量的神经纤维同步去极化才能引出良好波形。短声(click)能够在极短时间内达到最大强度,具有很好的
Auditory brainstem response (ABR) is a commonly used clinical method of auditory evoked potentials. It can be used to evaluate the objective hearing threshold in addition to the diagnostic test of auditory nerve access. ABR is a transient response, and only a large number of nerve fibers can depolarize simultaneously to induce a good waveform. Short click (click) to achieve maximum intensity in a very short time, with good
