In noise-exposed ears, the occurrence of threshold changes in the high frequency range (10 to 20 kHz) is earlier than that in the low frequency range (0.5 to 6 kHz).
接触噪声的各年龄组10~18 kHz阈值随年龄的增长而升高;不同工龄组比较,6~10年工龄组的10~18 kHz阈值明显升高;不同噪声强度组的10~20 kHz阈值比较差异无显著性(P>0.05)。

With ILO-92 Otodynamics Analyzer,distortion product otoacoustic emissionsat the 2 f1-f2 frequency were recorded from 86 normally hearing ears in response to four groups of different primary levels (L1=L2=75 dB SPL ; L1=L2=65 dB SPL ; L1=L2=60 dB SPL ; L1=65 dB SPL , L2=50 dB SPL).The average DPOAEs-gram demonstrated a bilobed contour with two peaks at approximately 1.5 kHz and 5 kHz and a "notch" between 2.5 kHz and 3 kHz.Moreover,the contour of DPOAEs-gram had no obvious changes with sex,ear or primary stimulus levels differences.
利用耳动态分析仪ILO-92,对48例听力正常人(86耳)在4组不同原始刺激强度下(L1=L2=75 dB SPL;L1=L2=65 dB SPL;L1=L2=60 dB SPL;L1=65 dB SPL,L2=50 dB SPL)进行畸变产物耳声发射检查,结果发现平均DPOAEs图呈双叶型轮廓:在1.5 kHz和5 kHz附近,2 f1-f2 DPOAEs存在两个高峰,在2.5~3 kHz附近存在一个低谷,此图型结构无性别、耳别差异。
