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。
The TEOAE signals of 10 (20 ears) preschoolers were re-treated with digital filtering and correlation function. The results show that the TEOAE signal after digital filtering and correlation processing is clearer and easier to identify than the original TEOAE signal waveform, which effectively improves the signal-to-noise ratio and recognition rate of the TEOAE signal.
