环境污染是健康的大敌,高强度的噪音会危害人们身康,引发身体或心理疾病。噪音影响睡眠质量,会导致头晕、失眠、引发记忆力减退、注意力不集中等神经衰弱症状,长期失眠会造成抑郁症等心理疾病。孕妇长时期在超出85分贝噪音环境下容易造成流产、早产,胎儿处在强噪音环境下会影响大脑发育,容易形成弱智儿。

消化系统方面,在强噪音下进食可致胃肠粘膜毛细血管发生极度收缩,使人唾液、胃液分泌减少,导致食欲不振,消化不良,容易患胃溃疡和十二指肠溃疡。研究表明,长期处于噪音超出85分贝的环境中,会造成听觉系统危害,头疼,记忆力下降,引发交感神经中枢紊乱,导致精神状态不稳定。当噪音高于90分贝人们思维和交谈不能进行,无法正常工作学习,新陈代谢受到影响。长期在强噪音环境下工作听力会严重受损,甚至耳聋。强烈的噪音使人的心跳加快、血压上升,容易导致心脏病发。

70分贝的噪音可致冠心病发病率增加30%,100分贝的噪音可使人的血压上升15%,这对患有心脏病或高血压病的人来说是十分危险的,强烈的噪音还会导致病人死亡。


Environmental pollution is the enemy of health, high-intensity noise will harm people's health, causing physical or mental illness. Noise affects the quality of sleep, leading to dizziness, insomnia, memory loss, inattention and other Neurasthenia, long-term Insomnia can cause depression and other mental illness. Pregnant women in the long-term more than 85 decibel noise environment easy to cause miscarriage, premature birth, fetus in a strong noise environment will affect brain development, easy to form mentally retarded. As for the digestive system, eating at high noise level may cause excessive contraction of the capillary Mucosa, resulting in decreased secretion of saliva and gastric juice, loss of appetite, indigestion, and susceptibility to peptic ulcer and peptic ulcer. Studies have shown that prolonged exposure to noise above 85 decibels can cause damage to the auditory system, headaches, memory loss, disorders of the sympathetic nervous system and mental instability. When the noise is above 90 decibels, people can not think and talk, can not work properly, and their metabolism is affected. Long-term work in strong noise environment will be seriously impaired hearing, and even deaf. Strong noise makes people's heart beat faster, blood pressure rise, easy to cause a heart attack. Noise of 70 decibels can increase the risk of coronary heart disease by 30 per cent, and 100 decibels can raise blood pressure by 15 per cent, which is dangerous for people with heart disease or high blood pressure. Loud noise can also cause death.
