噪声达到一定强度时听觉器官首受其害,同时中枢神经受到抑制并通过复杂的神经反射作用于视觉器官,影响人的视觉功能.暗适应能力减弱 视网膜上的杆细胞具有感受弱光的能力,在90分贝噪声环境中杆细胞的这种功能下降,以致识别弱光反应时间延长;当噪声值增至115分贝时,眼睛对光亮的适应性可降低20%.对瞳孔的影响 在噪声值为85分贝的环境中,40%的人瞳孔扩大,随着嗓声强度的增加瞳孔更为扩大.在70分贝噪声环境中,视力清晰度恢复到稳定状态只需20分钟;当噪声强度到达85分贝时则需一个多小时才可恢复.因此,在强 When the noise reaches a certain intensity, the auditory organ suffers first, while the central nervous system is suppressed and passes the complex neuroreflection on the visual organ, affecting human visual function. Dark adaptive ability reduces the ability of the rod cells in the retina to feel weak light, This function of the rod cells declines in the 90 dB noisy environment so that recognition of the weak light reaction time is prolonged, and the eye’s ability to adapt to light can be reduced by 20% when the noise value is increased to 115 dB.If the pupil is at a noise level of In the 85 dB environment, 40% of the pupils dilated and the pupil became larger as the intensity of the voice increased.Under the 70 dB noise environment, the clarity of vision returned to steady state in only 20 minutes. When the noise intensity reached 85 dB When it takes more than an hour to recover, so strong
