噪声超过人们所能耐受的程度就形成污染,称为噪声污染。噪声会损害听力,造成耳聋,这早已为大家所熟知。但是,随着环境医学对噪声危害的深入研究,人们发现它还会对人体其他组织器官造成更为严重的伤害。一、损伤眼睛。科学家发现,噪声能使人对光亮度的敏感性降低。经实验,当噪声强度在90分贝时,有2/5的人瞳孔扩大,视物模糊,而经常处于噪声环境中的人,容易出现眼疲劳、眼病、眼花和视物流泪等眼损伤现象。
Noise exceeds the level of people can tolerate the formation of pollution, known as noise pollution. Noise can impair hearing and cause deafness, which has long been known to all. However, with environmental medicine’s in-depth study of the harmful effects of noise, it has been found that it can also cause more serious damage to other tissues and organs of the human body. First, damage the eyes. Scientists have found that noise can make people less sensitive to light. Experiments show that when the noise intensity is 90 decibels, 2/5 people pupil dilation, blurred vision, and often in a noisy environment, prone to eye fatigue, eye disease, vertigo and visual material tears and other eye injuries.
