利用计算机信号处理技术，对８只（１６耳）豚鼠行耳蜗动作电位、脑干及原发听皮层三组诱发电位同线引导，可根据需要将电位曲线分若干段进行分析，得出ＡＢＣ三组电位正常时域与频域。结果提示，ＡＢＣ三组电位同线记录，既可以分析耳蜗动作电位、脑干电位以及皮层电位的各自特征，同时又可把三组电位作为一个整体，进行宏观分析。 Using computer signal processing technique, the evoked potential of the cochlear action potential, the brainstem and the primary auditory cortex of 8 guinea pigs were guided in line with each other. According to the analysis of potential curves, Group potential normal time and frequency domain. The results suggest that the three groups of ABC potentials recorded simultaneously, both the cochlear action potential, brainstem potential and cortical potential of the respective characteristics, but also the three groups of potential as a whole, macroscopical analysis.
