在聲(sheng)(sheng)源處抑制(zhi)噪(zao)聲(sheng)(sheng)，這是(shi)根本的(de)(de)措(cuo)施，主要是(shi)改革生產工藝(yi)和(he)技術(shu)革新(xin)，用(yong)低(di)(di)噪(zao)聲(sheng)(sheng)工藝(yi)代(dai)替高噪(zao)聲(sheng)(sheng)工藝(yi)，同時研(yan)究降(jiang)低(di)(di)噪(zao)聲(sheng)(sheng)源輻(fu)射噪(zao)聲(sheng)(sheng)的(de)(de)激(ji)振力(li)和(he)噪(zao)聲(sheng)(sheng)輻(fu)射部件(jian)對激(ji)振力(li)的(de)(de)響應。噪(zao)聲(sheng)(sheng)對兒(er)童身心健康危害(hai)更大。因兒(er)童發育尚未成熟(shu)，合肥降(jiang)噪(zao)，各組(zu)織十(shi)分(fen)嬌嫩(nen)和(he)脆弱，不論是(shi)體(ti)內的(de)(de)胎兒(er)還(huan)是(shi)剛出世的(de)(de)孩子(zi)，噪(zao)聲(sheng)(sheng)均可損(sun)傷(shang)聽覺(jue)官(guan)，使聽力(li)減退(tui)或喪(sang)失。噪(zao)聲(sheng)(sheng)還(huan)會導致交感神(shen)經緊張，代(dai)謝或微循環失調(diao)，引起血管(guan)系統疾病，發電廠噪(zao)聲(sheng)(sheng)治理，使人(ren)產生心跳加快、心律不齊、血管(guan)痙攣、血壓變化(hua)等癥狀。

噪(zao)(zao)音(yin)治理其(qi)實也(ye)是多(duo)性化的，通(tong)常(chang)(chang)由(you)于某種技術和(he)經濟上(shang)的原因，從聲(sheng)(sheng)源上(shang)控制噪(zao)(zao)聲(sheng)(sheng)難以(yi)實現，這時就要(yao)從傳播途徑(jing)上(shang)考慮降(jiang)噪(zao)(zao)措拖。噪(zao)(zao)聲(sheng)(sheng)還會使色覺、 視野(ye)發(fa)生(sheng)異常(chang)(chang)。調(diao)查發(fa)現噪(zao)(zao)聲(sheng)(sheng)對紅(hong)、藍、白三色視野(ye)縮(suo)小80％。所以(yi)駕駛員應避免立體場音(yin)響的噪(zao)(zao)聲(sheng)(sheng)干(gan)擾，商場噪(zao)(zao)聲(sheng)(sheng)治理，不然(ran)易造(zao)成(cheng)行車事(shi)故。 吸聲(sheng)(sheng)降(jiang)嗓(sang)降(jiang)低(di)的是無規人射的混響聲(sheng)(sheng)，無方向性混響聲(sheng)(sheng)產生(sheng)的嗓(sang)聲(sheng)(sheng)對人的干(gan)擾形(xing)響比(bi)(bi)較大(da)，它比(bi)(bi)降(jiang)低(di)同樣(yang)降(jiang)噪(zao)(zao)量的直達聲(sheng)(sheng)在主觀感(gan)覺上(shang)會有更(geng)好的效果。

噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)還會使色覺、 視(shi)野(ye)發生(sheng)異常。調查(cha)發現噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)對(dui)紅、藍、白三色視(shi)野(ye)縮(suo)小80％。所以駕駛員應避免立體場音響(xiang)的(de)(de)噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)干擾(rao)，不然易造成(cheng)行(xing)車事故。消(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)降噪(zao)(zao)(zao)消(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器是(shi)一種(zhong)既能(neng)(neng)使氣(qi)流通過(guo)(guo)又能(neng)(neng)有效地降低(di)(di)噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)的(de)(de)設(she)備(bei)。通常可用消(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器降低(di)(di)各種(zhong)空氣(qi)動(dong)力設(she)備(bei)的(de)(de)進出口或沿(yan)管(guan)道傳(chuan)遞的(de)(de)噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)。例如在內(nei)燃(ran)機(ji)(ji)、發電(dian)機(ji)(ji)組、冷卻(que)塔等。降低(di)(di)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)源的(de)(de)噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)輻射(she)是(shi)控制(zhi)噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)*根本的(de)(de)措施。通過(guo)(guo)對(dui)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)源發聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)機(ji)(ji)理(li)和(he)(he)機(ji)(ji)器設(she)備(bei)運行(xing)的(de)(de)深入研究，研制(zhi)新型的(de)(de)低(di)(di)噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)設(she)備(bei)以降低(di)(di)激(ji)發力，或改變操作程(cheng)序(xu)和(he)(he)改進加工工藝，均(jun)能(neng)(neng)顯著降低(di)(di)環境噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)。
