style="text-indent:25px">實(shí)際應(yīng)用中具體常見的吸聲材料有：多孔材料，比如礦棉、玻璃棉、泡沫塑料、毛氈等，這些吸聲材料本身都具有良好的中高頻吸收，背后留有空氣層時(shí)也能吸收低頻噪聲。板狀材料，如膠合板、石棉水泥板、石膏板、硬質(zhì)板，這些吸聲材料吸收低頻比較有效。穿孔板，主要像穿孔膠合板、穿孔石棉水泥板、穿孔石膏板、穿孔金屬板等，可以吸收中頻噪聲，與多孔材料結(jié)合使用吸收中高頻噪聲，和多孔材料一樣背后留空腔，也可以吸收低頻噪音。成型頂棚吸聲板，這類吸聲材料像礦棉吸聲板、玻璃棉吸聲板、軟質(zhì)纖維板，視質(zhì)地不同，密實(shí)不透氣的吸聲特性同硬質(zhì)板狀材料，透氣的同多孔材料。薄膜材料，如塑料薄膜、帆布、人造革等，是空氣層的厚薄而吸收低中頻噪聲。柔性材料，如海綿、乳膠塊，這類吸聲材料內(nèi)部氣泡不連通，與多孔材料不同，主要靠共振有選擇的吸收中頻。由于各種吸聲材料的吸聲特性有所不同，吸聲材料選擇時(shí)要考慮與周圍傳聲介質(zhì)的聲特性阻抗匹配，使聲能可以無反射地進(jìn)入吸聲材料，并使入射聲能絕大部分被吸收。</p><div
