噪音对心血管系统的影响,文献报导多局限于对血压的作用。多数学者指出,血压的升高取决于噪音的强度、频率的高低和作用的延续时间。作者检查了两组工人遭受恒定噪音影响的心血管系统,一组为人造纤维联合工厂捻线车间,另一组为滚珠轴承工厂滚珠车间的工人。工作地点噪音测定的结果表明,滚珠车间的噪音强度(114—120分贝)比捻线车间(85—95分贝)高。两个车间的噪音由中频和高频混合组成。工人的年龄大多在40岁以下。半数工人的工龄在10年以上。受检
The impact of noise on the cardiovascular system, the literature reported more limited to the role of blood pressure. Most scholars pointed out that the rise in blood pressure depends on the intensity of the noise, the frequency of the duration and duration of the effect. The authors examined two cardiovascular systems in which workers were exposed to constant noise. One was a man-made fiber joint factory twisting workshop and the other was a ball-bearing factory ball shop worker. The results of noise measurements at workplaces show that the noise floor of the ballroom (114-120 decibels) is higher than that of the twisting shop (85-95 decibels). The noise of the two workshops consists of a mixture of medium and high frequencies. Most of the workers are under the age of 40. Half of the workers are over 10 years old. Inspected
