消聲器是利用聲的吸收、反射、干涉等原理，降低通風與空調系統中氣流噪聲的裝置。沙坪壩通風管配件根據消聲原理的不同可以分為阻性、抗性、共振型和復合型等。一、阻性消聲器,阻性消聲器利用吸聲材料的吸聲作用而消聲的。其構造是把吸聲材料固定在氣流流動的管道內壁，高品質通風管配件或按一(yi)定方式(shi)排(pai)列在管(guan)道或殼體內(nei)構成阻性消聲器，吸聲材料能(neng)夠把入(ru)射(she)在其上的聲能(neng)部分地吸收(shou)掉(diao)。聲能(neng)之所以能(neng)被吸收(shou)，是由(you)于吸聲材料的多孔性和(he)松散性。當聲波進入(ru)孔隙，引起孔隙中(zhong)的空(kong)氣和(he)材料產生微小的振(zhen)動(dong)，由(you)于摩(mo)擦和(he)粘滯阻力。使相當一(yi)部分聲能(neng)化(hua)為(wei)熱能(neng)而(er)被吸收(shou)掉(diao)。
