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。
