There are only a few studies investigating the effects of ultrasound on hearing. This paper reports on an experimental investigation on the effect of the long-time exposure to a moderate sound pressure level, high-frequency sound of 16 kHz on the guinea pig inner ear using electrophysiological methods. A decrease of the absolute value of negative potential was observed in the endocochlear potential (EP). The effects of high-frequency sound on EP and electrochemical potential could be explained by a change in the K+ permeability of hair cells.
仅有少数研究调查了超声波对听力的影响。本文报告了一项实验研究，该研究采用电生理方法，探究了长时间暴露于16kHz的中等声压级高频声音对豚鼠内耳的影响。在内耳电位（EP）中观察到负电位绝对值降低。高频声音对EP和电化学电位的影响可以通过毛细胞钾离子通透性的变化来解释。
