style="font-size:16px;line-height:2;">隔音板與吸音棉作為兩種不同的聲學(xué)材料，在裝修中都是為了保證室內空間不被打擾，所以很多對聲學(xué)要求比較高的室內都會(huì )安裝一些隔音降噪的裝置，這樣能起到調節室內的聲學(xué)環(huán)境，兩種材料搭配在一起使用可以營(yíng)造更好的生活和工作環(huán)境。</span> </p> <p style="text-align:center;text-indent:2em;"> <span style="font-size:16px;line-height:2;"><img src="http://img.dlwjdh.com/upload/11990/210917/79ad050f570b6a67eb9d79edb0ffb2ab.jpg" alt="" /><br /> </span> </p> <p style="text-indent:2em;"> <span style="font-size:16px;line-height:2;">現在我們知道兩種材料都可以達到隔音降噪的效果，那它們之間的區別在哪呢？</span> </p> <p style="text-indent:2em;"> <span style="font-size:16px;line-height:2;">降噪原理不同</span> </p> <p style="text-indent:2em;"> <span style="font-size:16px;line-height:2;">吸音棉吸收的噪音聲波通過(guò)和材料內的無(wú)數空洞相互摩擦消耗來(lái)降噪，而隔音板是通過(guò)降低噪音聲波的穿透性，具有一定程度的減振效果。隔音板是一種高密度的隔音材料，使用隔音板能有效組織一部分的噪音向外輻射傳播，其..的特點(diǎn)就是隔音量大可達到30分貝。</span> </p> <p style="text-indent:2em;"> <span style="font-size:16px;line-height:2;">消音效果不同</span> </p> <p style="text-indent:2em;"> <span style="font-size:16px;line-height:2;">吸音棉具有消音效果，吸音材料能夠將吸收的聲波經(jīng)過(guò)內部的反復消耗，將聲能轉化為熱能消耗掉噪音以此達到降噪目的。隔音板可以阻斷噪音聲波的傳播，經(jīng)過(guò)在傳播途徑處的阻隔達到噪音治理的目的消音效果很差。</span> </p> <p style="text-indent:2em;"> <span style="font-size:16px;line-height:2;">在裝修吊頂的時(shí)候，采用隔音板就是相當于從基礎做隔離，就能夠有效的在根本上隔音。如果說(shuō)用吸音棉的話(huà)，那種是一般墻體未作隔音，所以才會(huì )從外部借助吸音棉來(lái)隔音，效果好還是隔音板來(lái)的好，希望對您有幫助。</span> </p> </div> <div
