The albino guinea pigs with normal Preyer's reflex were exposed to 2kHz pure tone of 80, 100 and 120dB SPL for 30, 60 and 120 minutes and the effects upon CM and AP were examined. The AP was far more sensitive to intense sound than CM and its threshold sift was proportional to the sound energy given to the animals, indicating the validity of the equal energy principle. The elevation of the AP threshold was the largest at 3kHz in case of 100dB×30 min but the largest elevation moved into 8kHz in 120dB×30min, whereas the CM was the most sensitive at 1kHz in any stimulus condition. The measurements 7 days after the exposure of the sound revealed the recovery of the potential was better in CM than AP. It was concluded that the response to the intense sound was different in CM and AP.
