| 摘 要： | 用数字滤波及相关函数处理技术对１０名（２０耳）学龄前儿童短声诱发的ＴＥＯＡＥ信号进行二次处理。结果表明：通过数字滤波及相关处理后的ＴＥＯＡＥ信号比原始记录的ＴＥＯＡＥ信号波形更加清晰，易于辨认，有效地提高了ＴＥＯＡＥ信号的信噪比及识别率。

| Abstract: | Using digital filtering and correlation function analysis technique,TEOAE waves in 20 ears(10 children)were managed two steps.The analysis results showed that the TEOAE signal waves after management were more clear and recognizable compared with this primary recording waves.This technique increased the signal noise ratio and recognizable rate of the TEOAE signals. |
