Guinea pigs were exposed to a 10 kHz pure tone and damage to the cochlea was investigated immediately after exposure, or after a recovery period ranging from 18-25 days. Structural damage was assessed using scanning electron microscopy and functional damage estimated using the N1 threshold audiogram. Exposure at 106 dB for 1 h caused obvious abnormalities of outer hair cell stereocilia. The location and extent of this damage was related to the immediate or long term deficits in the N1 threshold audiogram.
将豚鼠暴露于10千赫兹的纯音下，在暴露后立即或在18至25天的恢复期后，对耳蜗损伤情况进行研究。使用扫描电子显微镜评估结构损伤，使用N1阈值听力图估计功能损伤。在106分贝下暴露1小时会导致外毛细胞静纤毛出现明显异常。这种损伤的位置和程度与N1阈值听力图的即时或长期缺陷有关。
