Abstract

The influence of noise exposure on experimental bydrops in guinea pigs was studied morphologically with light and electron microscopy. Blood sludging and vasoconstriction were observed in the upper coild arterioles and capillaries of the stria vascularis in the 3rd and 4th turns of the cochlea, where outer hair cell loss was also noted.
These results suggest that circulatory disturbances following vasoconstriction are caused by noise exporsure, and eventually outer hair cells are damaged.
