介绍了耳声发射的产生机理和分类，论述了短声诱发耳声发射（ＣＥＯＡＥｓ）的实验及其提取方法．在锥形核时频分布方法的基础上，利用计算机及相应分析软件计算了来自具有正常听力人左右耳ＣＥＯＡＥｓ 的时频分布．根据试验和计算结果，讨论和分析了它们的时频分布特点及其相互关系，得出了对同一个具有正常听力人左右耳ＣＥＯＡＥｓ 的波形、主要发射频率的数目及持续时间具有相似性等结论．
The mechanism and classification of otoacoustic emissions were introduced. The experiments on short acoustic emission induced otoacoustic emissions (CEOAEs) and their extraction methods were discussed. Based on the conical kernel time-frequency distribution method, the time-frequency distributions of CEOAEs from the left and right ears of normal hearing persons were calculated by computer and corresponding analysis software. According to the results of experiments and calculations, the time-frequency distributions and their correlations are discussed and analyzed. The conclusions are drawn that there is similarity between the waveform of CEOAEs in the same left and right ear, the number of the main emission frequency and the duration .
