Abstract

The cochlea amplifies sound over a wide range of frequencies. Outer hair cells have been thought to play a mechanical part in this amplification, but it has been unclear whether they act rapidly enough. Recent work suggests that outer hair cells can indeed work at frequencies that cover the auditory range.

摘要

耳蜗在很宽的频率范围内放大声音。外毛细胞被认为在这种放大过程中起到机械作用，但它们的反应速度是否足够快尚不清楚。最近的研究表明，外毛细胞确实能够在覆盖听觉范围的频率下工作。
