继成功地记录出连续纯音诱发的听神经总合动作电位（ＣＡＰ）之后，我们又建立了提取不同频率连续纯音诱发的听觉脑干电位（ＡＢＲ）的新方法。连续纯音才是真正的纯音，用它作刺激声突破了ＣＡＰ和ＡＢＲ只能用“很不纯”的宽频瞬态声诱发的局限，有利于深入研究耳蜗及脑干水 Following the successful recording of auditory nerve total action potential (CAP) induced by continuous pure tone, we established a new method to extract auditory brain stem potential (ABR) induced by continuous pure tone at different frequencies. Continuous pure tone is the real pure tone, use it as a stimulus breakthrough CAP and ABR can only be “very impure” broadband transient sound induced limitations, is conducive to in-depth study of cochlear and brain stem water
