By examining 218 albino guinea pigs, electrophysiological methods were used to investigate the effects of low frequency ultrasound at moderate sound pressure levels after long-term exposure to the inner ear. From 10 kHz to 28 kHz, low frequency ultrasound below 100 dB SPL induced significant changes in cochlear microphonics, elevated thresholds and decreased maximum output voltage of action potentials and decreased absolute values of negative potentials of the endocochlear potentials.
通过对218只白化豚鼠进行检查，采用电生理方法研究了长期暴露于内耳后，中等声压级的低频超声的影响。在10千赫至28千赫范围内，声压级低于100分贝声压级的低频超声引起了耳蜗微音器电位的显著变化、阈值升高、动作电位最大输出电压降低以及内淋巴电位负电位绝对值降低。
