Guinea pigs were exposed to 20 kHz for a period of 1 or 2 h, with and without an intermediate recovery period. Statistically smaller areas of damage were obtained after doubling the exposure time, especially without a recovery period. For a double exposure with a recovery period the areas of damage were the same as for the single exposures.
将豚鼠暴露于20千赫兹的环境中1或2小时，有无中间恢复期。在暴露时间加倍后，尤其是没有恢复期的情况下，损伤区域在统计学上较小。对于有恢复期的双重暴露，损伤区域与单次暴露相同。
