最初的听觉生理研究是Bekesy等进行的,认为基膜波为一依频率而定的宽、平曲线。Page等间接观察动物,尚发现有一伴一百倍高振幅且非常尖而小的波出现。40年前Gold即提出,基膜不仅只具有被动的生物力学性质,在听生理活动中有其主动的生物力学功能参与。最有力的证据是在人和动物的外耳道内记录到从哺乳动物的耳蜗发生的自发听反射(SOAE)的能量需求(Fritze等)。SOAE可用一高敏度传声器在外部收集到一听刺激的正弦曲线信号,频率局限在1～3KHz之间,个别病例上
The earliest physiological study of hearing was conducted by Bekesy et al., Which considered the basement membrane wave as a broad, flat curve depending on the frequency. Page and other indirect observation of animals, still found one hundred times the high amplitude and very sharp and small waves appear. 40 years ago, Gold proposed that the basement membrane not only has passive biomechanical properties, but also has active biomechanical functions involved in listening to physiological activities. The most compelling evidence is the need to record spontaneous auditory reflexes (SOAEs) from the mammalian cochlea (Fritze et al.) In human and animal external auditory meatus. SOAE can use a high-sensitivity microphone to collect an exciting sinusoidal signal, the frequency is limited to between 1 ~ 3KHz, in individual cases
