[Cerebral hemodynamics in persons subjected to exposure to intensive industrial noise].

Correlation of cerebral hemodynamic disorders, levels of arterial pressure and degree of hearing loss was examined by means of calibrometry of retina vessels in 318 mechanical engineering workers exposed to intensive industrial noise. Workers with hearing impairments had higher rates of arterial hypertension than those with preserved hearing. Circulatory disorders in the cerebral microvascular system were detected both for elevated and normal arterial pressure and they were caused primarily by arteriole hypertonus. As the hearing analyzer function decreased, the trend to the reduction of tone disorders appeared.
