Guinea pigs have been exposed to 20 kHz for 2 h, 1 h, 30 min, 15 min, or 7.5 min, and the resultant damage was observed 3, 6, and 12 weeks post exposure. The areas of outer hair cell damage were statistically compared. Significant differences were obtained after a 3-week survival time with the shorter exposure times, but this difference was no longer apparent after 12 weeks. Myelinated nerve fibre and inner hair cell damage occurred only with total outer hair cell loss.
豚鼠暴露于20千赫兹的环境中2小时、1小时、30分钟、15分钟或7.5分钟，并在暴露后3周、6周和12周观察由此产生的损伤。对外毛细胞损伤的面积进行了统计学比较。在3周的存活期后，较短的暴露时间产生了显著差异，但在12周后这种差异不再明显。有髓神经纤维和内毛细胞损伤仅在全部外毛细胞丧失时才会发生。
