研究發現，噪(zao)(zao)(zao)聲(sheng)(sheng)超過85分(fen)(fen)貝，會使(shi)人感到(dao)心(xin)煩(fan)意亂(luan)，人們(men)會感覺到(dao)吵鬧，因(yin)而無(wu)法專心(xin)地工(gong)作(zuo)，結果會導致工(gong)作(zuo)效率降低(di)。 在(zai)進行(xing)廠(chang)房設(she)計時，應合理地配置聲(sheng)(sheng)源。把產生強烈(lie)噪(zao)(zao)(zao)聲(sheng)(sheng)的(de)(de)工(gong)廠(chang)與居民區，高(gao)噪(zao)(zao)(zao)聲(sheng)(sheng)的(de)(de)車(che)間(jian)與低(di)噪(zao)(zao)(zao)聲(sheng)(sheng)的(de)(de)車(che)間(jian)分(fen)(fen)開(kai)，也可減少噪(zao)(zao)(zao)聲(sheng)(sheng)的(de)(de)危害(hai)。控(kong)制和(he)消除噪(zao)(zao)(zao)聲(sheng)(sheng)源，這是(shi)防止噪(zao)(zao)(zao)聲(sheng)(sheng)危害(hai)的(de)(de)根(gen)(gen)本措施；應根(gen)(gen)據具體(ti)情況采取不同的(de)(de)解決方式。采用(yong)無(wu)聲(sheng)(sheng)或(huo)低(di)聲(sheng)(sheng)設(she)備代替發出噪(zao)(zao)(zao)聲(sheng)(sheng)的(de)(de)設(she)備，如用(yong)液壓代替高(gao)噪(zao)(zao)(zao)聲(sheng)(sheng)的(de)(de)鍛壓，以焊接(jie)代替鉚接(jie)，用(yong)無(wu)梭代替有(you)梭織(zhi)布等，均(jun)可受(shou)到(dao)較好的(de)(de)效果。

噪聲(sheng)(sheng)(sheng)(sheng)在(zai)低頻時，一般無指向性，但隨著頻率(lv)的(de)(de)增長，其指向性也隨著增加。因此，對于高頻噪聲(sheng)(sheng)(sheng)(sheng)，改變指向是(shi)一項控制(zhi)(zhi)噪聲(sheng)(sheng)(sheng)(sheng)的(de)(de)、行之有效(xiao)的(de)(de)對策(ce)。這就象(xiang)大氣污染(ran)控制(zhi)(zhi)中(zhong)要求考慮(lv)學年(nian)主導風(feng)向，辦公樓、生活區建在(zai)上風(feng)向。在(zai)噪聲(sheng)(sheng)(sheng)(sheng)控制(zhi)(zhi)工(gong)程中(zhong)經常(chang)(chang)采用(yong)的(de)(de)有效(xiao)技術有吸聲(sheng)(sheng)(sheng)(sheng)、隔聲(sheng)(sheng)(sheng)(sheng)、阻尼和(he)隔振等。常(chang)(chang)見的(de)(de)吸聲(sheng)(sheng)(sheng)(sheng)墻、吸聲(sheng)(sheng)(sheng)(sheng)吊頂、隔聲(sheng)(sheng)(sheng)(sheng)屏障、隔聲(sheng)(sheng)(sheng)(sheng)門(men)、隔聲(sheng)(sheng)(sheng)(sheng)窗、消聲(sheng)(sheng)(sheng)(sheng)器(qi)和(he)隔振地(di)板等，則是(shi)這些(xie)技術的(de)(de)具體應用(yong)。

在聲(sheng)源(yuan)處抑制噪(zao)(zao)(zao)(zao)(zao)聲(sheng)，這(zhe)是(shi)根本的措施，發(fa)電廠噪(zao)(zao)(zao)(zao)(zao)聲(sheng)治理(li)，主(zhu)要是(shi)改革生產(chan)工(gong)(gong)藝和技術革新，用低噪(zao)(zao)(zao)(zao)(zao)聲(sheng)工(gong)(gong)藝代替(ti)高噪(zao)(zao)(zao)(zao)(zao)聲(sheng)工(gong)(gong)藝，同時研究降低噪(zao)(zao)(zao)(zao)(zao)聲(sheng)源(yuan)輻射噪(zao)(zao)(zao)(zao)(zao)聲(sheng)的激振力和噪(zao)(zao)(zao)(zao)(zao)聲(sheng)輻射部件對激振力的響應。噪(zao)(zao)(zao)(zao)(zao)聲(sheng)對兒(er)(er)童身心(xin)健康危害更大。因(yin)兒(er)(er)童發(fa)育(yu)尚(shang)未成熟，各組織十分嬌嫩和脆弱，不(bu)(bu)論是(shi)體內的胎兒(er)(er)還是(shi)剛(gang)出世(shi)的孩子，噪(zao)(zao)(zao)(zao)(zao)聲(sheng)均可損傷聽覺官，使(shi)聽力減退(tui)或喪(sang)失(shi)(shi)。噪(zao)(zao)(zao)(zao)(zao)聲(sheng)還會(hui)導致(zhi)交感(gan)神經緊張，代謝或微循環失(shi)(shi)調，引(yin)起(qi)血(xue)管系統疾病，使(shi)人產(chan)生心(xin)跳加(jia)快、心(xin)律不(bu)(bu)齊、血(xue)管痙攣、血(xue)壓變化等癥狀。
