style="text-indent:25px">吸音棉是多孔吸聲材料，當(dāng)聲波在空氣中引起振動(dòng)時(shí)，吸音棉透氣性的物理參數(shù)會(huì)使微量的空氣從多孔材料的孔隙中通過(guò)，此時(shí)材料的兩面的靜壓差和氣流線速度之間的比就是材料的流阻。吸引材料的內(nèi)部微孔數(shù)量、大小以及互相連通的程度等因素都會(huì)影響流阻的大小，流阻的大小對(duì)材料吸音作用有著重要的影響。一定厚度的多空材料應(yīng)該對(duì)應(yīng)一個(gè)合理的流阻數(shù)值，過(guò)高或過(guò)低都會(huì)影響材料的吸音性能。因此，要對(duì)材料的流阻進(jìn)行調(diào)整，將流阻值控制在科學(xué)的范圍內(nèi)，發(fā)揮出其比較大的作用。湖南玻璃棉卷氈哪家好</p><p
