根據現場測量(liang)(liang)出(chu)的噪(zao)(zao)聲(sheng)(sheng)(sheng)源(yuan)以及相關環(huan)(huan)境標準所容許的噪(zao)(zao)聲(sheng)(sheng)(sheng)級之差確定降(jiang)噪(zao)(zao)量(liang)(liang)，進(jin)行方案設計(ji)。施(shi)(shi)工結(jie)束后，根據《聲(sheng)(sheng)(sheng)環(huan)(huan)境質量(liang)(liang)標準（GB3096-2008）》要求(qiu)，對施(shi)(shi)工區(qu)域進(jin)行環(huan)(huan)境噪(zao)(zao)聲(sheng)(sheng)(sheng)檢(jian)測，噪(zao)(zao)聲(sheng)(sheng)(sheng)治(zhi)理(li)公司，針對不(bu)同區(qu)域的噪(zao)(zao)聲(sheng)(sheng)(sheng)標準不(bu)同。環(huan)(huan)境噪(zao)(zao)聲(sheng)(sheng)(sheng)污染一(yi)般是由聲(sheng)(sheng)(sheng)源(yuan)、傳播途(tu)徑和受主三個(ge)(ge)基本環(huan)(huan)節(jie)組成的。因(yin)此，噪(zao)(zao)聲(sheng)(sheng)(sheng)治(zhi)理(li)必須把這三個(ge)(ge)環(huan)(huan)節(jie)作為(wei)一(yi)個(ge)(ge)系統(tong)進(jin)行研究。

用(yong)(yong)(yong)一種(zhong)能阻止(zhi)聲(sheng)(sheng)(sheng)音傳(chuan)播(bo)而允許氣流通(tong)過的(de)(de)(de)(de)裝置，即消(xiao)聲(sheng)(sheng)(sheng)器。這(zhe)是防止(zhi)空(kong)氣動(dong)力(li)性噪(zao)聲(sheng)(sheng)(sheng)的(de)(de)(de)(de)主要措施。消(xiao)聲(sheng)(sheng)(sheng)器有利(li)用(yong)(yong)(yong)吸(xi)聲(sheng)(sheng)(sheng)材料消(xiao)聲(sheng)(sheng)(sheng)的(de)(de)(de)(de)阻性消(xiao)聲(sheng)(sheng)(sheng)器，根(gen)(gen)據濾波(bo)原(yuan)理制(zhi)造的(de)(de)(de)(de)抗性消(xiao)聲(sheng)(sheng)(sheng)器，以(yi)及(ji)利(li)用(yong)(yong)(yong)上(shang)述兩種(zhong)原(yuan)理設(she)計的(de)(de)(de)(de)阻抗復合消(xiao)聲(sheng)(sheng)(sheng)器。控制(zhi)和消(xiao)除噪(zao)聲(sheng)(sheng)(sheng)源，這(zhe)是防止(zhi)噪(zao)聲(sheng)(sheng)(sheng)危害(hai)的(de)(de)(de)(de)根(gen)(gen)本(ben)措施；應根(gen)(gen)據具體情況采取不同的(de)(de)(de)(de)解決方式。采用(yong)(yong)(yong)無(wu)聲(sheng)(sheng)(sheng)或低聲(sheng)(sheng)(sheng)設(she)備代替發(fa)出噪(zao)聲(sheng)(sheng)(sheng)的(de)(de)(de)(de)設(she)備，如(ru)用(yong)(yong)(yong)液壓(ya)代替高噪(zao)聲(sheng)(sheng)(sheng)的(de)(de)(de)(de)鍛壓(ya)，以(yi)焊接(jie)代替鉚接(jie)，用(yong)(yong)(yong)無(wu)梭(suo)代替有梭(suo)織布等(deng)，均可(ke)受到較好的(de)(de)(de)(de)效果(guo)。

控(kong)制和(he)消除噪(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)源(yuan)，這是(shi)防止(zhi)噪(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)危(wei)害的(de)(de)根(gen)本措施；應根(gen)據(ju)具體(ti)情況采取不(bu)同的(de)(de)解決方式。采用無聲(sheng)(sheng)(sheng)(sheng)(sheng)或低(di)聲(sheng)(sheng)(sheng)(sheng)(sheng)設備代替發出噪(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)的(de)(de)設備，降(jiang)(jiang)噪(zao)(zao)處理，如(ru)用液壓(ya)代替高噪(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)的(de)(de)鍛(duan)壓(ya)，以焊接代替鉚接，隔(ge)音降(jiang)(jiang)噪(zao)(zao)施工單(dan)價，用無梭代替有(you)梭織布等(deng)，安慶(qing)降(jiang)(jiang)噪(zao)(zao)，均可受(shou)到較好的(de)(de)效(xiao)果。在(zai)噪(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)控(kong)制工程中經常采用的(de)(de)有(you)效(xiao)技術(shu)有(you)吸聲(sheng)(sheng)(sheng)(sheng)(sheng)、隔(ge)聲(sheng)(sheng)(sheng)(sheng)(sheng)、阻(zu)尼和(he)隔(ge)振等(deng)。常見的(de)(de)吸聲(sheng)(sheng)(sheng)(sheng)(sheng)墻、吸聲(sheng)(sheng)(sheng)(sheng)(sheng)吊頂、隔(ge)聲(sheng)(sheng)(sheng)(sheng)(sheng)屏障、隔(ge)聲(sheng)(sheng)(sheng)(sheng)(sheng)門、隔(ge)聲(sheng)(sheng)(sheng)(sheng)(sheng)窗、消聲(sheng)(sheng)(sheng)(sheng)(sheng)器和(he)隔(ge)振地板等(deng)，則是(shi)這些技術(shu)的(de)(de)具體(ti)應用。噪(zao)(zao)音治理其(qi)實(shi)也是(shi)多性(xing)化的(de)(de)，通常由于某(mou)種技術(shu)和(he)經濟上(shang)的(de)(de)原因，從聲(sheng)(sheng)(sheng)(sheng)(sheng)源(yuan)上(shang)控(kong)制噪(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)難以實(shi)現，這時就要從傳播途徑上(shang)考慮降(jiang)(jiang)噪(zao)(zao)措拖(tuo)。
