目的 旨在探讨ASSR 与ABR 在极重度感音神经性耳聋幼儿及成人感音神经性耳聋患者测试中的临床应用价值。

Methods Eighty-six subjects with normal and abnormal hearing(172 ears) were tested with ASSR and PTA at 500,1 000,2 000,4 000 Hz to get the thresholds of ASSR and PTA.

方法对听力正常的志愿者及不同听力水平的感音神经性聋的志愿者共86例(172耳)，分别行PTA及500、1000、2000和4000Hz的ASSR，得出PTA阈值及ASSR阈值。

Methods Tb-ABR and ASSR were performed on 10 normal hearing adults (20 ears); the response thresholds at 0.5,1,2 and 4 kHz were recorded for analysis.
