Acoustic trauma effects from doubling the exposure time
Tóm tắt
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.
