對(dui)于室內高(gao)噪(zao)聲(sheng)的(de)(de)(de)、要求防(fang)爆(bao)、需散(san)熱且(qie)換氣量較大、頻(pin)繁(fan)操作或維修的(de)(de)(de)，降(jiang)噪(zao)工程(cheng)施(shi)工，等(deng)多種大型機械設備，都不(bu)宜采用隔(ge)(ge)聲(sheng)罩(zhao)的(de)(de)(de)形式，消(xiao)音(yin)降(jiang)噪(zao)工程(cheng)施(shi)工，設置一(yi)定(ding)高(gao)度的(de)(de)(de)室內聲(sheng)屏障就(jiu)可以(yi)起到(dao)一(yi)定(ding)的(de)(de)(de)降(jiang)噪(zao)效果。聲(sheng)在傳播中的(de)(de)(de)能量是隨(sui)著距(ju)離的(de)(de)(de)增加而衰減(jian)的(de)(de)(de)，因此使(shi)噪(zao)聲(sheng)源遠離需要安靜(jing)的(de)(de)(de)地方(fang)，可以(yi)達到(dao)降(jiang)噪(zao)的(de)(de)(de)目的(de)(de)(de)。隔(ge)(ge)聲(sheng)罩(zhao)與(yu)聲(sheng)源設備不(bu)得有任(ren)何剛性連接，以(yi)免引(yin)起罩(zhao)體振動，輻(fu)射噪(zao)聲(sheng)。在設計隔(ge)(ge)聲(sheng)罩(zhao)時要注意縫隙孔(kong)洞漏聲(sheng)，做好結構(gou)上節點的(de)(de)(de)連接。

降(jiang)噪(zao)，顧(gu)名(ming)思義就(jiu)是減少噪(zao)音對人的(de)影響(xiang)。常用的(de)方法有：1、隔聲(sheng)(sheng)(sheng)(sheng)房；2、安裝消(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)器；3、隔聲(sheng)(sheng)(sheng)(sheng)屏障(zhang)；4、減振等。降(jiang)噪(zao)處(chu)理措施：消(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)：使(shi)用消(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)器降(jiang)低空(kong)氣動(dong)力性噪(zao)聲(sheng)(sheng)(sheng)(sheng)，如各種風(feng)機、空(kong)壓機排風(feng)口等進、排氣噪(zao)聲(sheng)(sheng)(sheng)(sheng)。采(cai)用吸(xi)聲(sheng)(sheng)(sheng)(sheng)材料裝飾在車間的(de)內表面，如墻壁和屋頂，或者在車間內懸掛空(kong)間吸(xi)聲(sheng)(sheng)(sheng)(sheng)體(ti)，環保降(jiang)噪(zao)工程公司，吸(xi)收輻射和反射聲(sheng)(sheng)(sheng)(sheng)能，使(shi)噪(zao)聲(sheng)(sheng)(sheng)(sheng)強度減低。

聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)屏(ping)(ping)(ping)障(zhang)在室(shi)外(wai)是(shi)(shi)控制交(jiao)通(tong)噪(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)污染(ran)常見(jian)的(de)(de)有效(xiao)措(cuo)施，在交(jiao)通(tong)干(gan)線(xian)(xian)兩側設置聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)屏(ping)(ping)(ping)障(zhang)，以降(jiang)低(di)干(gan)線(xian)(xian)兩側的(de)(de)交(jiao)通(tong)噪(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)。對(dui)于聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)屏(ping)(ping)(ping)障(zhang)設計，安徽降(jiang)噪(zao)工程，聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)屏(ping)(ping)(ping)障(zhang)本(ben)身要有足(zu)夠的(de)(de)隔聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)量(liang)，否則透射聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)能過(guo)大(da)，就(jiu)起不到隔聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)效(xiao)果。為(wei)了(le)防(fang)止通(tong)過(guo)地板和(he)墻(qiang)(qiang)壁(bi)(bi)等固體(ti)(ti)材(cai)料傳播(bo)(bo)的(de)(de)振動噪(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)，在機器的(de)(de)基礎和(he)地板、墻(qiang)(qiang)壁(bi)(bi)聯結處設減(jian)(jian)振裝(zhuang)置，如膠(jiao)墊、瀝(li)青等。吸(xi)(xi)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)材(cai)料吸(xi)(xi)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)系數越(yue)(yue)大(da)，吸(xi)(xi)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)面積越(yue)(yue)多，吸(xi)(xi)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)效(xiao)果越(yue)(yue)明顯，可以利用吸(xi)(xi)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)天花、吸(xi)(xi)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)墻(qiang)(qiang)體(ti)(ti)、空(kong)(kong)間吸(xi)(xi)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)體(ti)(ti)等進(jin)行吸(xi)(xi)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)降(jiang)噪(zao)。消(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)技(ji)術(shu)主要用于降(jiang)低(di)管道(dao)中(zhong)傳播(bo)(bo)的(de)(de)噪(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)。消(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器就(jiu)是(shi)(shi)一種能讓(rang)氣流或水流通(tong)過(guo)，使噪(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)衰減(jian)(jian)的(de)(de)裝(zhuang)置，通(tong)常安裝(zhuang)在管道(dao)中(zhong)或進(jin)、排口上，可有效(xiao)降(jiang)低(di)從空(kong)(kong)氣中(zhong)或水流中(zhong)傳傳播(bo)(bo)的(de)(de)動力(li)性噪(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)。
