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.
通过视网膜血管校准测量法，对318名暴露于高强度工业噪声中的机械工程工人的脑血流动力学紊乱、动脉压水平和听力损失程度之间的相关性进行了研究。听力受损的工人比听力正常的工人患动脉高血压的比例更高。在动脉压升高和正常的情况下，均检测到脑微血管系统的循环紊乱，其主要由小动脉张力亢进引起。随着听力分析器功能的下降，出现了张力紊乱减少的趋势。
