在雙方確(que)定(ding)好(hao)方案簽署合同后，在日期內將材料、施(shi)(shi)工(gong)設備運抵施(shi)(shi)工(gong)現場，施(shi)(shi)工(gong)人(ren)員進場作業。整個(ge)工(gong)程施(shi)(shi)工(gong)時(shi)(shi)嚴格(ge)按照設計方案進行，根據工(gong)程量大小(xiao)制定(ding)施(shi)(shi)工(gong)周期，在約定(ding)時(shi)(shi)間(jian)內完成。聲(sheng)(sheng)源(yuan)可以(yi)是(shi)(shi)單(dan)個(ge)，也可以(yi)是(shi)(shi)多個(ge)同時(shi)(shi)作用;傳播(bo)途徑(jing)也常不(bu)(bu)只一條，且非固定(ding)不(bu)(bu)變;受(shou)主可能(neng)是(shi)(shi)人(ren)，也可能(neng)是(shi)(shi)若干靈敏設備，對噪(zao)(zao)聲(sheng)(sheng)的反(fan)應也各不(bu)(bu)相同。根據現場測量出的噪(zao)(zao)聲(sheng)(sheng)源(yuan)以(yi)及相關環(huan)境(jing)標準所容許的噪(zao)(zao)聲(sheng)(sheng)級之差確(que)定(ding)降噪(zao)(zao)量，進行方案設計。

噪(zao)聲(sheng)還會導致(zhi)交感神經緊張，代謝或微循(xun)環失調，引起系統(tong)疾病，使人產生心(xin)跳加快(kuai)、心(xin)律(lv)不(bu)齊、血管(guan)痙攣(luan)、血壓(ya)變化等癥狀(zhuang)。更廣泛(fan)的(de)講，凡是妨(fang)礙人們學習、工(gong)作和休息并使人產生不(bu)舒適感覺的(de)聲(sheng)音(yin)，都叫(jiao)“噪(zao)音(yin)”，同樣也包括流水(shui)聲(sheng)、敲擊(ji)聲(sheng)、沙沙聲(sheng)，機械聲(sheng)等具有規則波(bo)形的(de)噪(zao)音(yin)。在雙方(fang)確定(ding)好方(fang)案(an)簽署合同后，在日期(qi)內將材料、施工(gong)設(she)備運抵施工(gong)現場，施工(gong)人員進場作業。整個工(gong)程施工(gong)時嚴格(ge)按(an)照設(she)計(ji)方(fang)案(an)進行，根據工(gong)程量大小制定(ding)施工(gong)周期(qi)，電梯降(jiang)噪(zao)，在約定(ding)時間(jian)內完成。

解決(jue)噪(zao)(zao)(zao)音問題的(de)(de)一般程序是(shi)(shi)(shi)(shi)首(shou)行現場(chang)噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)調查，測(ce)量(liang)現場(chang)的(de)(de)噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)聲(sheng)(sheng)(sheng)(sheng)級和噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)頻率(lv)，分(fen)析從聲(sheng)(sheng)(sheng)(sheng)源到接(jie)收者的(de)(de)傳輸(shu)途徑，對不同的(de)(de)噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)源所產生(sheng)的(de)(de)噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)聲(sheng)(sheng)(sheng)(sheng)級進行排序量(liang)化噪(zao)(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)問題。方案整(zheng)體需要考慮到技術是(shi)(shi)(shi)(shi)否(fou)可行，價格是(shi)(shi)(shi)(shi)否(fou)在(zai)(zai)客(ke)戶(hu)所接(jie)受的(de)(de)范圍內等，根據整(zheng)體情況制定一套(tao)或多(duo)套(tao)合理的(de)(de)方案供客(ke)戶(hu)選擇。隔聲(sheng)(sheng)(sheng)(sheng)屏障(zhang)的(de)(de)主要作用是(shi)(shi)(shi)(shi)遮(zhe)擋直(zhi)達聲(sheng)(sheng)(sheng)(sheng)，其作用只(zhi)有在(zai)(zai)屏障(zhang)的(de)(de)聲(sheng)(sheng)(sheng)(sheng)影區(qu)較為(wei)顯著，屏障(zhang)越(yue)靠(kao)近(jin)聲(sheng)(sheng)(sheng)(sheng)源，聲(sheng)(sheng)(sheng)(sheng)影區(qu)越(yue)大，隔聲(sheng)(sheng)(sheng)(sheng)區(qu)域(yu)越(yue)大，隔聲(sheng)(sheng)(sheng)(sheng)效果越(yue)明顯。
