<P>　　在家庭裝修過(guò)程中，很多人都為隔音材料的選擇而猶豫不決，不知道該從哪兒開(kāi)始，由于現在隔音材料的分類(lèi)也很多，有隔音的、吸音的、減震的等等，面對諸多的隔音材料種類(lèi)，我們該如何選擇呢？而關(guān)于隔音材料我們又了解多少呢？這些確實(shí)都是很現實(shí)的問(wèn)題，下面我們一起來(lái)做一個(gè)簡(jiǎn)單的了解。<BR>　　隔音材料有很多種，一般人們常見(jiàn)的有：建筑隔音材料、KTV隔音材料、裝修隔音材料、隔音減振材料、減震降震材料、吸音裝飾材料、裝飾吸音棉板、隔音板、隔音防火材料等。<BR>　　隔音材料五花八門(mén)，日常人們比較常見(jiàn)的有實(shí)心磚塊、鋼筋混泥土墻、木板、石膏板、鐵板、隔聲氈、纖維板等等。嚴格意義上說(shuō)，幾乎所有的材料都具有隔音作用，其區別就是不同材料間隔音量的大小不同而已。同一種材料，由于面密度不同，其隔音量存在比較大的變化。隔音量遵循質(zhì)量定律原則，就是隔音材料的單位密集面密度越大，隔音量就越大，面密度與隔音量成正比關(guān)系。<BR>隔音是指通過(guò)某種物品把聲音或噪音隔絕、隔斷、分離等，因此就需要隔音材料。隔音材料通過(guò)對聲源或聲音的傳播途徑來(lái)隔絕聲音。<BR>　　目前高層塔樓的隔墻一般采用輕質(zhì)隔墻，帶來(lái)的相應問(wèn)題是隔墻的隔音功能下降。人們也曾嘗試過(guò)補救辦法，比如用吸音棉和石膏板做一層隔墻，但效果很不好。根本解決辦法還是使用專(zhuān)業(yè)的隔聲材料，可采用的隔音材質(zhì)有隔音氈、厚窗簾、吸音棉、壁紙等，在裝修過(guò)程中，還可以通過(guò)安裝隔音門(mén)窗，并在家具、飾物等小地方動(dòng)些小手術(shù)，也同樣可以達到消除噪音的效果。<BR>　　頭頂的聲音解決辦法其實(shí)很簡(jiǎn)單，就是用專(zhuān)業(yè)的隔聲材料做專(zhuān)門(mén)的隔音吊頂。一般來(lái)說(shuō)，天花板最好也是吸音與擴散兼具，當然，您必須把做天花板的預算編入房屋裝修裝飾費用里。否則，天花板隨便一做就是一兩萬(wàn)。但可以采用輕鋼架加礦纖板的方法，這是最簡(jiǎn)單的天花板處理，也是最省錢(qián)的處理，一般最多也就是上千元。<BR>　　木質(zhì)家具有纖維多孔性的特征，能吸收噪音。同時(shí)，也應適度購置家具，家具過(guò)少會(huì )使聲音在室內共鳴回旋，增加噪音。<BR>　　布藝裝飾布藝品也有不錯的吸音效果，懸垂與平鋪的織物，其吸音作用和效果是一樣的，如窗簾、地毯等等，其中以窗簾的隔音作用最為明顯。既能吸音，又有很好的裝飾效果，是不錯的選擇。<BR>　　復生噪音治理專(zhuān)家提醒：隔音材料在物理上有一定彈性，當聲波入射時(shí)便激發(fā)振動(dòng)在隔層內傳播。當聲波不是垂直入射，而是與隔層呈一角度θ入射時(shí)，聲波波前依次到達隔層表面，而先到隔層的聲波激發(fā)隔層內彎曲振動(dòng)波沿隔層橫向傳播，若彎曲波傳播速度與空氣中聲波漸次到達隔層表面的行進(jìn)速度一致時(shí)，聲波便加強彎曲波的振動(dòng)，這一現象稱(chēng)吻合效應。這時(shí)彎曲波振動(dòng)的輻度特別大，并向另一面空氣中輻射聲波的能量也特別大，從而使隔音效果降低。<BR><BR><BR>
