噪声有什么危害?希望简短一点,一两句话就行,
噪声有什么危害?希望简短一点,一两句话就行,
噪声有什么危害?希望简短一点,一两句话就行,
你拿每点第一句话写写就可以了
1、损害听力.有关资料表明:当人连续听摩托车声,8小时以后听力就会受损; 若是在摇滚音乐厅,半小时后,人的听力就会受损;若在80分贝以上的噪音环境中生活,造成耳聋的可能性可达50%.
2、噪音损害视力
噪音会严重影响听觉器官,甚至使人丧失听力,尽人皆知.然而,耳朵与眼睛之间有着微妙的内在“联系”,当噪音作用于听觉器官时,也会通过神经系统的作用而“波及”视觉器官,使人的视力减弱.
研究指出,噪音可使色觉、色视野发生异常.调查发现,在接触稳态噪音的80名工人中,出现红、绿、白三色视野缩小者竟高达80%,比对照组增加85%.
噪音对视力的影在日常生活中随处可见,比如在安静明亮的商店购物时,显得愉快和镇静,买东西能做到挑选精细购买齐全.而在高音喇叭大声播放快节奏的流行音乐(一些所谓的流行音乐,只不过是震耳欲聋的强噪音)时购物,往往烦燥不安,眼花缭乱,甚至会混胡乱交易,该买的未买,买了的因识别不细也不满意.其中的主要原因就是燥音影响视力造成的的.
3、有害于人的心血管系统、我国对城市噪音与居民健康的调查表明:地区的噪音每上升一分贝,高血压发病率就增加3%.
4、影响人的神经系统,使人急躁、易怒.
科学研究发现,噪音可刺激神经系统,使之产生抑制,长期在噪音环境下工作的人,还会引起神经衰弱症候群(如头痛、头晕、耳鸣、记忆力衰退、视力降低等).
5、 影响睡眠,造成疲倦.
噪声对睡眠的危害:突然的噪声在40分贝时,可使10%的人惊醒,达到60分贝时,可使70%的人惊醒.

危害人体健康,造成污染.
1.影响听力:长时间暴露在噪声中,可使听力严重下降。
2.突然暴露在过强分贝的噪音下,可使人听力丧失。
噪声可以造成人体暂时性和持久性听力损伤。一般来说,85分贝以下的噪声不至于危害听觉,而超过100分贝时,将有近一半的人耳聋。 3.引起人体其他疾病。一些
妨碍人们的生活、工作与学习,有害健康等
