人的七窍是相通的 ,耳朵与眼睛之间有微妙的内在联系。当噪音作用于听觉器官时 ,会通过神经系统而波及视觉器官 ,使人的视力减弱。有人做过实验 ,当噪音强度在 90分贝时 ,视网膜区别光亮的敏感性开始下降 ,识别弱光反应时间也延长 ;当噪音达到 115分贝时 ,眼睛对光亮的适应性下 The seven oysters are interlinked, and there is a subtle connection between the ears and the eyes. When noise acts on the auditory organ, it affects the visual organ through the nervous system, diminishing the visual acuity of the human being. Someone has done experiments, when the noise intensity at 90 decibels, retina difference began to decline in the sensitivity of light to recognize the weak light reaction time is also extended; when the noise reaches 115 decibels, the eyes of the light adaptability
