外毛细胞（OHCs）以其能动特性，被认为是耳蜗放大器的细胞基础。刺激OHCs导致传导波放大其100～IO00倍的振幅和传导尖峰，同时OHCS产生耳声发射（OAES）。传导波波幅与波峰两者都与听觉过程的感受和频率选择有关。感受性乃为纯音听敏度阈值的基础。频率选择是日常生活语言识别
Outer hair cells (OHCs) are considered the cellular basis of the cochlear amplifier for their dynamic properties. Stimulation of OHCs causes conduction waves to amplify their 100-1000-fold amplitude and conduction spikes while OHCS produces otoacoustic emissions (OAES). Conducted wave amplitude and peak both with the auditory process of feeling and frequency selection. Sensitivity is the basis for pure tone hearing sensitivity threshold. Frequency selection is everyday language recognition
