背景资料：本研究探讨了在安静的语音识别分数和参数的皮层电位（P1，N1和P2的潜伏期和振幅的N1/P2）在individuals with auditory neuropathy.Methods：10个人与听神经病（5男5女）和10个人与正常听力在12至39岁的年龄范围内参加了这项研究。语音识别能力进行了评估，为双音节的话和皮层电位记录为点击stimulation.Results：结果显示，在个人与听神经病，语音识别分数显着较差的个人听力正常。根据听神经病患者的言语识别分数，将其进一步分为两组，表现良好者和表现不佳者。结果表明，听力不良者的N1/P2平均波幅显著低于听力良好者和听力正常者。各组对各峰潜伏期无明显影响。言语识别分数表现出良好的相关性与皮层电位（N1/P2复合）的振幅，但没有表现出显着的相关性与皮层potential.Conclusion的潜伏期：本研究的结果表明，测量皮层电位可能提供了一种方法，用于预测个人的感知技能与听神经病。
Background: Present study investigated the relationship between speech identification scores in quiet and parameters of cortical potentials (latency of P1, N1, and P2; and amplitude of N1/P2) in individuals with auditory neuropathy.Methods: Ten individuals with auditory neuropathy (five males and five females) and ten individuals with normal hearing in the age range of 12 to 39 yr participated in the study. Speech identification ability was assessed for bi-syllabic words and cortical potentials were recorded for click stimuli.Results: Results revealed that in individuals with auditory neuropathy, speech identification scores were significantly poorer than that of individuals with normal hearing. Individuals with auditory neuropathy were further classified into two groups, Good Performers and Poor Performers based on their speech identification scores. It was observed that the mean amplitude of N1/P2 of Poor Performers was significantly lower than that of Good Performers and those with normal hearing. There was no significant effect of group on the latency of the peaks. Speech identification scores showed a good correlation with the amplitude of cortical potentials (N1/P2 complex) but did not show a significant correlation with the latency of cortical potentials.Conclusion: Results of the present study suggests that measuring the cortical potentials may offer a means for predicting perceptual skills in individuals with auditory neuropathy.
