噪声损害人的听觉器官,已人所共知。随着科学的发展,专家还发现噪声还能影响人的视觉,使眼对光亮度的敏感性降低。 实验证实:当噪声强度在90分贝(A)时,视网膜中视杆细胞区别光亮度的敏感性开始下降,识别弱光反应的时间也延长;当噪声达到95分贝(A)时,有2/5的人瞳孔扩大;达到115分贝(A)时,眼对光亮度的适应性降低20％。有的研究还指出,在噪声强度大的环境 Noise damage to human auditory organs, has been well-known. With the development of science, experts also found that noise can also affect people’s vision, so that the sensitivity of the eye to light is reduced. Experiments show that when the noise intensity is 90 decibels (A), the sensitivities of distinguishing the brightness of the rods in the retina begin to decline, and the time of recognizing the weak light reaction also prolongs. When the noise reaches 95 decibels (A), there are 2/5 Of pupils dilated; reaching 115 decibels (A), the ocular response to light was reduced by 20%. Some studies have also pointed out that in the noise-intensive environment
