隔(ge)聲(sheng)屏(ping)對于一些無法全封閉的場所(suo)應用(yong)(yong)(yong)(yong)較(jiao)廣，它主要起(qi)到聲(sheng)音吸收(shou)和阻擋(dang)的作(zuo)用(yong)(yong)(yong)(yong)。隔(ge)聲(sheng)屏(ping)采用(yong)(yong)(yong)(yong)低(di)密(mi)度(du)的材(cai)料(liao)(吸聲(sheng)棉、泡沫玻璃等(deng))來吸聲(sheng)和高密(mi)度(du)的材(cai)料(liao)(鋼(gang)板、磚墻等(deng))來隔(ge)聲(sheng)。高頻噪(zao)聲(sheng)在(zai)繞過障(zhang)礙(ai)物的能力比較(jiao)差，所(suo)以隔(ge)聲(sheng)屏(ping)主要是(shi)用(yong)(yong)(yong)(yong)來阻擋(dang)高頻噪(zao)聲(sheng)的。

隔(ge)聲問是(shi)在高噪(zao)聲環境中(zhong)隔(ge)出一個安靜的環境，以供(gong)工人觀察(cha)控(kong)(kong)制(zhi)機器運轉或(huo)是(shi)休(xiu)(xiu)息用，可作為控(kong)(kong)制(zhi)室(shi)(shi)、觀察(cha)室(shi)(shi)、值班室(shi)(shi)、休(xiu)(xiu)息室(shi)(shi)、測聽室(shi)(shi)等用。

設(she)計原理　　將阻(zu)(zu)性(xing)及抗性(xing)等(deng)不同消(xiao)(xiao)聲(sheng)(sheng)原理組合設(she)計即構(gou)成(cheng)了復(fu)臺式消(xiao)(xiao)聲(sheng)(sheng)器，如阻(zu)(zu)抗復(fu)合消(xiao)(xiao)聲(sheng)(sheng)器，阻(zu)(zu)共振(zhen)復(fu)合式消(xiao)(xiao)聲(sheng)(sheng)器等(deng)，都是工程(cheng)中常見的消(xiao)(xiao)聲(sheng)(sheng)器。由于阻(zu)(zu)性(xing)消(xiao)(xiao)聲(sheng)(sheng)器雖有(you)優良的中高(gao)頻(pin)消(xiao)(xiao)聲(sheng)(sheng)性(xing)能(neng)，而(er)低頻(pin)消(xiao)(xiao)聲(sheng)(sheng)性(xing)能(neng)則較差(cha)(cha)，而(er)且也難以提(ti)高(gao)，而(er)擴(kuo)張式及共振(zhen)式消(xiao)(xiao)聲(sheng)(sheng)器則相反(fan)，在低中頻(pin)具有(you)較好的消(xiao)(xiao)聲(sheng)(sheng)性(xing)能(neng)，高(gao)頻(pin)消(xiao)(xiao)聲(sheng)(sheng)效果一般都較差(cha)(cha)。如果將阻(zu)(zu)性(xing)與(yu)抗性(xing)兩種消(xiao)(xiao)聲(sheng)(sheng)原理合成(cheng)一種消(xiao)(xiao)聲(sheng)(sheng)器，就(jiu)可(ke)以在較寬的頻(pin)率范圍內都能(neng)得到滿(man)意的消(xiao)(xiao)聲(sheng)(sheng)效果。因(yin)此，無論是通風

設計原(yuan)理　　小(xiao)(xiao)孔(kong)噴(pen)注消(xiao)聲(sheng)(sheng)(sheng)器(qi)是(shi)一(yi)種(zhong)(zhong)直(zhi)徑(jing)大于原(yuan)排(pai)氣(qi)(qi)(qi)(qi)口(kou)而(er)末端封閉的(de)(de)消(xiao)聲(sheng)(sheng)(sheng)器(qi)，其管壁上開有很(hen)多的(de)(de)的(de)(de)排(pai)氣(qi)(qi)(qi)(qi)小(xiao)(xiao)孔(kong)，小(xiao)(xiao)孔(kong)的(de)(de)總面積一(yi)般應大于原(yuan)排(pai)氣(qi)(qi)(qi)(qi)管口(kou)的(de)(de)面積，小(xiao)(xiao)孔(kong)的(de)(de)直(zhi)徑(jing)愈小(xiao)(xiao)，降低排(pai)氣(qi)(qi)(qi)(qi)噪聲(sheng)(sheng)(sheng)的(de)(de)效果也(ye)愈好(hao)，常(chang)見(jian)小(xiao)(xiao)孔(kong)噴(pen)注消(xiao)聲(sheng)(sheng)(sheng)器(qi)的(de)(de)小(xiao)(xiao)孔(kong)孔(kong)徑(jing)為(wei)1mm左右，這種(zhong)(zhong)小(xiao)(xiao)孔(kong)噴(pen)注消(xiao)聲(sheng)(sheng)(sheng)器(qi)的(de)(de)結構就是(shi)將原(yuan)來單個大直(zhi)徑(jing)排(pai)氣(qi)(qi)(qi)(qi)噴(pen)口(kou)改為(wei)大量小(xiao)(xiao)孔(kong)噴(pen)口(kou)，其降低噪聲(sheng)(sheng)(sheng)的(de)(de)原(yuan)理是(shi)基于小(xiao)(xiao)孔(kong)噴(pen)注噪聲(sheng)(sheng)(sheng)頻譜的(de)(de)改變，即(ji)當通過小(xiao)(xiao)孔(kong)的(de)(de)氣(qi)(qi)(qi)(qi)流速度足夠(gou)高(gao)時，小(xiao)(xiao)孔(kong)能將排(pai)氣(qi)(qi)(qi)(qi)噪聲(sheng)(sheng)(sheng)的(de)(de)頻譜移(yi)向高(gao)頻
