为了进一步探讨耳声发射的产生机制 ,需要研究不同类型刺激诱发的耳声发射之间的相互关系。主要研究短声与短纯音诱发的耳声发射 ,用广义时频分析方法中的锥形核分布分别计算了它们的时频分布 ,从其时频分布分析了它们之间的相互关系。结果表明 :具有不同中心频率的短纯音刺激诱发耳声发射的时频分布的迭加与短声刺激诱发的耳声发射的时频分布具有相似性 ,两者时频分布中的主要频率成分数目、潜伏期和持续时间完全相同 ,它们高度的相关性支持了短声与短纯音诱发的耳声发射具有共同的产生器的观点。
In order to further explore the mechanism of otoacoustic emissions, we need to study the relationship between different types of stimuli-induced otoacoustic emissions. The main research is the short sound and short pure tone induced otoacoustic emissions, the generalized time-frequency analysis of the cone-shaped nuclear distribution were calculated their time-frequency distribution, from the time-frequency distribution of the relationship between them analyzed. The results show that the short-tone stimulation-induced otoacoustic emissions time-frequency distributions of short pure tone stimulation-induced otoacoustic emissions have similar time-frequency distribution, the frequency components of the two main frequency components , The latency and duration are exactly the same, and their high correlation supports the notion of a common generator of short and simple pure tone-induced otoacoustic emissions.
