人类听觉脑干诱发电位的频谱特征与时序模型分析

The Study of Characterized Parameters in Brainstem Evoked Responses

本文用频谱分析与时序模型的方法对正常听力与异常听力的受试BAEP进行了分析。由结果看出,正常BAEP较听力障碍BAEP带宽、频谱幅度大。此外,时序模型分析提示,参数|λK|max对听阈的判别也有意义,也许可作为一种辅助指标。由在a_1,e_0划分可以看出,在a_1、e_0构成的平面上二者可得到完全的分离。

In this paper, we analyzed BAEP by using frequency analysis and time series model analysis. The results indicate that time series model is an effective analysis meth od for BAEP analysing, the parameter |λi|max may be an index to estimate the threshold of hearing orcritical condition, the idenxification function based on a_1, e_0 may be used to diagnosis the subject's hearing condition in clinical field.
