Abstract

The noise has become a very important (stress factor) for the human community especially in industrial cities. The aim of this study was to investigate the relationship between occupational noise level with arterial blood pressure (systolic and diastolic), heart rate , pulse pressure, mean arterial pressure for some workers from industrial region (Black smiths, Lath machine), Generators and Grinders. The data were collected between (The first of November -2015 to the Thirty of January -2016).The study group included (60) workers in various professions and exposed to the industrial noise levels with mean (97.25dB), with mean age (30.35) years and mean weight (72.46) Kg and mean height (168.86) cm. The control group consist of (30) subjects with mean age (31.45) years and mean weight (66.37) Kg and mean height(162.93)cm. taken from students and staff members of Missan university with some donors who never lived or worked in noisy environment. The results of this study showed significant changes in (P<0.05) for systolic and diastolic blood pressure, heart rate, pulse pressure , mean arterial pressure in the workers for all occupations . It is concluded from this study that the industrial noise could be causal factor for cardiovascular disturbances and increase the blood pressure and heart rate in the workers during exposure to the industrial noise.
