Abstract
Noise is a stress factor which stimulates the hypothalamopituitary-adrenal axis, the medulla of the suprarenal gland, and the sympathetic nervous system. Consequently, there occurs an increase in the release of circulating »stress« hormones: ACTH, cortisol, adrenaline and noradrenaline. The effect of noise ds likely to be more pronounced in experimental animals than in man. An unknown intense sound provokes fear in animals, and increases the stress effect of noise. In acoustic studies in humans »the expecting stress« must be reduced to a minimum by fully anforming the examinee about the aim and course of the experiment, and about the non-harmful effect on health. The reticular formation, colliculus inferior laminae quadrigeminae mesencephali, and corpus geniculatum mediale might be the ways for relaying nervous impulses from acoustic pathways to the hypothalamus under intense noise.
