1、消聲性能：鍍鋅薄鋼板風管：無消聲性能，自身震動會產生聲音，必須加裝消聲器。無機玻璃鋼風管：無消聲性能，隔聲性能優于鍍鋅薄鋼板風管，必須加裝消聲器。復合玻纖板風管：其管壁是一種多孔性吸聲材料，可省去專用消聲器。纖維織物風管：其管壁為柔性纖維織物，電動防火閥批發本身就是聲音的不良導體和吸收體，自身不會產生聲音，推薦電動防火閥還可以一定程度(du)上(shang)吸收設備(bei)噪聲，隨著(zhu)管道的延長，效果更(geng)為明顯，可省去專用消聲器。2、保溫(wen)(wen)性(xing)(xing)能(neng)：鍍鋅(xin)薄鋼(gang)板風(feng)(feng)(feng)管：導(dao)熱系數(shu)很大(為60.4 W/m?K)，無(wu)(wu)保溫(wen)(wen)性(xing)(xing)能(neng)，必須另外加包保溫(wen)(wen)層及保護層。無(wu)(wu)機玻璃鋼(gang)風(feng)(feng)(feng)管：導(dao)熱系數(shu)大(為0.5W/m?K)，無(wu)(wu)保溫(wen)(wen)性(xing)(xing)能(neng)。復(fu)合(he)玻纖板風(feng)(feng)(feng)管：導(dao)熱系數(shu)小(平均溫(wen)(wen)度(du)24℃時小于(yu)1W/m?K)，有一定保溫(wen)(wen)性(xing)(xing)能(neng)，不(bu)加裝保溫(wen)(wen)。

消(xiao)聲(sheng)(sheng)(sheng)器是(shi)利用(yong)聲(sheng)(sheng)(sheng)的(de)(de)(de)吸(xi)收(shou)(shou)、反射、干(gan)涉等原理，降低通風與空(kong)調系統中氣流(liu)噪(zao)聲(sheng)(sheng)(sheng)的(de)(de)(de)裝置。根據(ju)消(xiao)聲(sheng)(sheng)(sheng)原理的(de)(de)(de)不同可(ke)以分為(wei)阻(zu)性(xing)、抗性(xing)、共振(zhen)型和(he)復合(he)型等。一(yi)(yi)、阻(zu)性(xing)消(xiao)聲(sheng)(sheng)(sheng)器,阻(zu)性(xing)消(xiao)聲(sheng)(sheng)(sheng)器利用(yong)吸(xi)聲(sheng)(sheng)(sheng)材(cai)料(liao)(liao)的(de)(de)(de)吸(xi)聲(sheng)(sheng)(sheng)作用(yong)而消(xiao)聲(sheng)(sheng)(sheng)的(de)(de)(de)。其(qi)構造(zao)是(shi)把吸(xi)聲(sheng)(sheng)(sheng)材(cai)料(liao)(liao)固定在(zai)(zai)氣流(liu)流(liu)動的(de)(de)(de)管(guan)道內壁(bi)，或(huo)按一(yi)(yi)定方式排列在(zai)(zai)管(guan)道或(huo)殼體內構成(cheng)阻(zu)性(xing)消(xiao)聲(sheng)(sheng)(sheng)器，吸(xi)聲(sheng)(sheng)(sheng)材(cai)料(liao)(liao)能(neng)夠把入(ru)射在(zai)(zai)其(qi)上的(de)(de)(de)聲(sheng)(sheng)(sheng)能(neng)部(bu)分地吸(xi)收(shou)(shou)掉。聲(sheng)(sheng)(sheng)能(neng)之所(suo)以能(neng)被吸(xi)收(shou)(shou)，是(shi)由(you)于吸(xi)聲(sheng)(sheng)(sheng)材(cai)料(liao)(liao)的(de)(de)(de)多孔性(xing)和(he)松散性(xing)。當(dang)聲(sheng)(sheng)(sheng)波(bo)進(jin)入(ru)孔隙，引起孔隙中的(de)(de)(de)空(kong)氣和(he)材(cai)料(liao)(liao)產生微小的(de)(de)(de)振(zhen)動，由(you)于摩擦和(he)粘滯阻(zu)力。使相當(dang)一(yi)(yi)部(bu)分聲(sheng)(sheng)(sheng)能(neng)化為(wei)熱能(neng)而被吸(xi)收(shou)(shou)掉。
