本文利用耳声发射分析仪ＣＥＬＥＳＴＡ５０３对２０名正常听力青年人进行了ＤＰＯＡＥ和ＴＥＯＡＥ测试，结果发现平均ＤＰＯＡＥ图中有两个反应高峰，分别位于１ｋＨｚ和６ｋＨｚ附近，两峰之间于３ｋＨｚ左右有一反应低谷。左右耳及性别差异对ＤＰＯＡＥ无显著性影响。ＤＰＯＡＥ的反应幅值随两个初始纯音强度的增加而升高，平均检测阈值在３０～４５ｄＢＳＰＬ之间。当初始音强度≤７０ｄＢＳＰＬ时，平均Ｉ／Ｏ函数曲线未见明显饱和现象。若采用不等强度的初始纯音（Ｌ１＝７０ｄＢＳＰＬ，Ｌ１－Ｌ２＝５ｄＢ）刺激，在中频部分（１．５～４ｋＨｚ）可获得较等强度初始纯音刺激时高的ＤＰＯＡＥ反应。由８０ｄＢｐｅＳＰＬ短声诱发的ＴＥＯＡＥ检出率为１００％，平均幅值４．１１±３．９９ｄＢＳＰＬ（ｘ±ｓ）。两种耳声发射之间有显著相关性。
In this study, 20 normal hearing young people were subjected to the DPOAE and TEOAE tests using the Cochlear Echo Analyzer CELESTA503. The results showed that there were two reaction peaks in the average DPOAE plot, located at around 1 kHz and 6 kHz, respectively. There was a low reaction between the two peaks at about 3 kHz . Left and right ears and gender differences have no significant effect on DPOAE. The response amplitude of DPOAE increased with the increase of two initial pure tones, and the average detection threshold was between 30 and 45 dBSPL. When the initial sound intensity is less than or equal to 70dBSPL, the average I / O function curve shows no obvious saturation phenomenon. The DPOAE response was higher in the mid-frequency range (1.5-4 kHz) than in the initial intensity-pure tone stimulus when stimulated with an initial intensity of unequal intensity (L1 = 70 dB SPL, L1-L2 = 5 dB). The detection rate of TEOAE induced by 80dBpeSPL short-tone was 100% with an average amplitude of 4.11 ± 3.99dB SPL (x ± s). There was a significant correlation between the two otoacoustic emissions.
