Abstract:
Noise is a common occupational hazardous factor in the workplace. In addition to the specific damage to the auditory
，
system of workers it can also harm the cardiovascular system and cause a serious disease burden. The mechanism of
，
occupational noise on the cardiovascular system of workers is mainly oxidative stress inflammation and vascular endothelial
， - - -
damage. As a stressor noise mainly leads to the changes of sympathoadrenal medullary system and hypothalamic pituitary
， ， ， - ，
adrenal axis. The substances that play an important role include catecholamines cortisol angiotensin Ⅱ endothelin 1
-
endothelial nitric oxide synthase and interleukin 6. The population epidemiological studies have shown that occupational noise
，
exposure can lead to elevated blood pressure abnormal electrocardiogram and elevated blood lipids in workers. The influencing
（ ， ， ）
factors include noise characteristics intensity cumulative noise exposure and frequency and noise combined with other

occupational hazards such as high temperature welding fumes organic solvents hand transmitted vibration and work

shifts . However due to the influence of research conditions experimental design and other factors some research conclusions
still have limitations. More prospective and comprehensive studies are needed to verify the relevant conclusions in the future.
