環(huán)境污染是健康的大敵，高強度的噪音會危害人們身康,引發(fā)身體或心理疾病。噪音影響睡眠質(zhì)量，會導(dǎo)致頭暈、失眠、引發(fā)記憶力減退、注意力不集中等神經(jīng)衰弱癥狀，長期失眠會造成抑郁癥等心理疾病。孕婦長時期在超出85分貝噪音環(huán)境下容易造成流產(chǎn)、早產(chǎn)，胎兒處在強噪音環(huán)境下會影響大腦發(fā)育，容易形成弱智兒。

消化系統(tǒng)方面，在強噪音下進(jìn)食可致胃腸粘膜毛細(xì)血管發(fā)生極度收縮,使人唾液、胃液分泌減少，導(dǎo)致食欲不振，消化不良，容易患胃潰瘍和十二指腸潰瘍。研究表明，長期處于噪音超出85分貝的環(huán)境中，會造成聽覺系統(tǒng)危害，頭疼，記憶力下降，引發(fā)交感神經(jīng)中樞紊亂，導(dǎo)致精神狀態(tài)不穩(wěn)定。當(dāng)噪音高于90分貝人們思維和交談不能進(jìn)行，無法正常工作學(xué)習(xí)，新陳代謝受到影響。長期在強噪音環(huán)境下工作聽力會嚴(yán)重受損，甚至耳聾。強烈的噪音使人的心跳加快、血壓上升，容易導(dǎo)致心臟病發(fā)。

70分貝的噪音可致冠心病發(fā)病率增加30%，100分貝的噪音可使人的血壓上升15%，這對患有心臟病或高血壓病的人來說是十分危險的，強烈的噪音還會導(dǎo)致病人死亡。
