消(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器是(shi)利用(yong)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)的(de)(de)(de)吸(xi)收、反射、干涉等原理，降(jiang)低通風(feng)與(yu)空(kong)調系統(tong)中(zhong)氣流(liu)噪聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)的(de)(de)(de)裝置。根(gen)據(ju)消(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)原理的(de)(de)(de)不(bu)同可以分為(wei)(wei)阻(zu)(zu)性(xing)(xing)(xing)、抗性(xing)(xing)(xing)、共(gong)振型和(he)(he)(he)復合型等。一、阻(zu)(zu)性(xing)(xing)(xing)消(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器,阻(zu)(zu)性(xing)(xing)(xing)消(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器利用(yong)吸(xi)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)材(cai)料的(de)(de)(de)吸(xi)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)作用(yong)而消(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)的(de)(de)(de)。其構造(zao)是(shi)把吸(xi)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)材(cai)料固定(ding)在氣流(liu)流(liu)動(dong)的(de)(de)(de)管道內壁(bi)，或(huo)按一定(ding)方式排列在管道或(huo)殼體內構成阻(zu)(zu)性(xing)(xing)(xing)消(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器，吸(xi)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)材(cai)料能(neng)(neng)夠把入射在其上的(de)(de)(de)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)能(neng)(neng)部(bu)分地吸(xi)收掉。聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)能(neng)(neng)之所以能(neng)(neng)被(bei)(bei)吸(xi)收，是(shi)由于吸(xi)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)材(cai)料的(de)(de)(de)多孔(kong)性(xing)(xing)(xing)和(he)(he)(he)松(song)散性(xing)(xing)(xing)。當聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)波進入孔(kong)隙(xi)，引(yin)起孔(kong)隙(xi)中(zhong)的(de)(de)(de)空(kong)氣和(he)(he)(he)材(cai)料產生微小的(de)(de)(de)振動(dong)，由于摩擦(ca)和(he)(he)(he)粘滯阻(zu)(zu)力。使相當一部(bu)分聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)能(neng)(neng)化為(wei)(wei)熱能(neng)(neng)而被(bei)(bei)吸(xi)收掉。
