在不同中耳病变耳中，鼓室负压组teoae测试结果各观察值明显低于正常耳及其它各组。
Among the different disorders, the group with negative middle ear pressure was obviously low in TEOAE.
结果利用人耳数值模型进行正常耳和病变耳的谐响应分析，得到正常耳和病变耳镫骨底板和鼓膜凸的振幅变化规律。
Result Amplitude variation laws of the stapes footplate and umbo were obtained by comparing the frequency response analytic results between the normal ear and pathological ear.
结果表明：无CAS作用下，TEOAE频域信号的近似熵在各频带处，蜗性病变耳的近似熵明显低于正常耳的近似熵，蜗后病变耳的近似熵与正常耳的近似熵无明显差别。
The results show that, compared with a normal ear, the approximate entropy of TEOAE without CAS was reduced for cochlear hearing loss, while it did not change for retrocochlear hearing loss.
