Abstract

Guinea Pig spiral organs damaged by exposure of the animal to 125 dB whitenoise for 2 hours were studied under scanning electron-microscope.Pronounceddegenerative changes were found only in specimens taken a month after exposure.However,in the specimens taken immediately after exposure slight early changes,such-as scattering, lying prostrate,or loss of hairs of the hair cells,could be clearlyobserved which were difficult to be identified with phase-contrast microscope inthe usual surface-preparation.
