style="text-indent:25px">眾所周知，汽車在怠速、加速或不同路面行駛狀態(tài)下而產(chǎn)生的噪聲，經(jīng)底盤和車體產(chǎn)生共振或共鳴后將噪聲放大而傳入車內(nèi)，令駕乘者感到不適。由于聲音是經(jīng)過振動來傳播的。所以隔音工程是運用專業(yè)聲學產(chǎn)品停止車體減振及車內(nèi)吸音，從噪聲的傳播途徑上停止隔除。隔音工程主要經(jīng)過以下兩個途徑來處置：（1）運用減振隔音材料來到達消音降噪的目的。例如：在車門、行李底盤等處粘貼減振隔音材料后，它會起到加固車體構造和控制車體與外界噪聲的共振的作用。這是由于粘貼減振隔音材料后。改動車體的固有頻率，控制車外噪聲與車體產(chǎn)生的共振和共鳴，從而有效隔除車個噪聲。（2）運用吸音材料來到達消音降噪的目的。例如：在發(fā)起機艙蓋運用吸音材料后發(fā)起機的噪聲明顯降低。這是由于吸音材料是一種聲學泡沫材料，它里面程度散布著啟齒腔與閉口腔，能有效地將噪聲即聲能轉(zhuǎn)化為機械能和熱能耗費掉，從而到達吸收噪聲的目的這兩種材料的運用并不是**的，配合運用會到達較佳效果。</p><p style="text-indent:25px">新車買回來，多數(shù)人還是會選擇為汽車加裝一些配件或者裝飾，例如發(fā)動機下護板、晴雨擋或者隔音棉，一般來說，原廠就帶有隔音棉的車型，隔音棉的用料都比較厚實，并且采用卡扣固定的方法，看上去非常規(guī)整美觀，而后期加裝的隔音棉又有專車**的塑料植絨+耐高溫阻燃材料的隔音棉和自由裁剪的鋁箔隔音棉之分。專車**的也多是采用卡扣的方式進行固定，因為廠家一般都會在在機蓋上預留卡扣位置，且尺寸貼合，而自由裁剪的鋁箔隔音棉的安裝則需要多費一些功夫。無論是加裝哪種類型的隔音棉，肯定的是，汽車隔音降噪是一個系統(tǒng)工程，單憑這一塊隔音棉顯然不會起到什么作用。從媒體上實測的隔音效果來看，有沒有隔音棉并沒有明顯的區(qū)別。所以，如果你只是單純?yōu)榱烁粢艚翟?，還是去做個整車隔音比較合適，因為一塊隔音棉真的起不了什么作用。隔音棉不含石棉，甲醛，苯，施工條件好。</p><div

style="text-indent:25px">隔音棉有用嗎？隔音棉原理：物體震動產(chǎn)生聲音→聲波在空氣中傳遞→棉具有多纖維結(jié)構→聲波通過棉時經(jīng)過無數(shù)纖維的反射、相互疊加、碰撞，聲波能量轉(zhuǎn)化為熱能→聲波強度減弱→聲音消失。隔音棉另外一個作用就是隔熱，就它可以減少發(fā)動機運轉(zhuǎn)傳到引擎蓋表面的熱量，安裝的時候，注意有引擎蓋隔音棉的車輛雨天時基本不會產(chǎn)生白霧。陰雨天和冬天，由于外部氣溫與發(fā)動機溫差較大，再加上雨水等對引擎蓋的沖刷等共同作用，會加速漆面的氧化。個人家里的下水管也是包了隔音棉的，它的噪音也明顯地比以前沒有包隔音棉的時候要小得很多很多。連云港機蓋隔音棉價錢</p><p style="text-indent:25px">隔音棉分為聚酯纖維隔音棉和玻璃纖維隔音棉。連云港機蓋隔音棉價錢</p><p style="text-indent:25px">隔音棉和隔音板的區(qū)別一，兩者的安裝環(huán)境不一樣。隔音板通常安裝在固定的地方，例如室內(nèi)。隔音棉可以放在能移動的物體上，如粘貼在汽車引擎蓋內(nèi)。隔音棉和隔音板的區(qū)別二，兩者的工作原理不同。隔音板通過其的高密度特性能阻止部分噪音的傳播，可以隔絕30分貝以下的噪聲。隔音棉具有吸音效果，其材料內(nèi)有大量的孔洞，噪音的聲波通過隔音棉會與這些孔洞相與摩擦從而達到降低噪音的作用。隔音棉和隔音板的區(qū)別三，兩者對隔音的效果不同。隔音板主要是通過嚴密的材料隔絕噪音，保證室內(nèi)的安靜，多用于對環(huán)境安靜要求較高的地方。隔音棉是通過孔洞與噪音的摩擦來消音，把噪音轉(zhuǎn)化為熱能。那么隔音棉和隔音板到底哪種更好呢？這兩種都是較為常用的隔音材料，只能說各有優(yōu)點和缺點吧，隔音棉安裝較為方便，使用方式更便捷，但是會發(fā)熱。隔音板隔絕效果更加好，但是容易引起音波的反射。所以在實際應用中，我們應該根據(jù)實際情況選擇使用哪種隔音材料。像密封的鐵皮盒這些隔音差的地方，用隔音板的效果更好，要是一些像墻壁和木箱這些隔音量較高的位置，則用吸音棉更好。連云港機蓋隔音棉價錢</p></p><br
