style="text-indent:25px">吸音材料的作用原理聲音源于物體的振動，它引起鄰近空氣的振動而形成聲波，并在空氣介質(zhì)中向四周傳播。當聲音傳入構(gòu)件材料表面時，聲能一部分被反射，一部分穿透材料，還有一部由于構(gòu)件材料的振動或聲音在其中傳播時與周圍介質(zhì)摩擦，由聲能轉(zhuǎn)化成熱能，聲能被損耗，即通常所說聲音被材料吸收。吸聲系數(shù) 材料吸聲性能的好壞，用吸聲系數(shù)α表示。 Α為損耗系數(shù)E吸/E0與穿透系數(shù)E透/ E0之和。材料的吸聲性能除與材料本身結(jié)構(gòu)、厚度及材料的表面特征有關(guān)外，還和聲音的入射方向和頻率有關(guān)。天津吸音雞蛋棉供應(yīng)雞蛋棉安裝也可以直接用釘子釘在墻上（注意釘子頭部大?。?/p><div

style="text-indent:25px">怎么消除噪音？雞蛋棉是個不錯的選擇。人類一直在尋找降低噪音的辦法，特別是一些特殊的行業(yè)就需要噪音越小越好，通常降低噪音有三種辦法。一種方法是在發(fā)聲的源頭上控制噪音，也就是說讓發(fā)聲體減小或者是停止振動，這種辦法是從發(fā)聲源頭直接讓噪音消失，當直接讓發(fā)聲源停止振動后，就沒有辦法持續(xù)在空氣中產(chǎn)生振動。第二種就是在人接收聲音的耳朵處將噪音阻隔在外，例如說帶上耳塞就能有效的降低噪音進入人耳的音量，即便是不改變發(fā)聲源和傳播途徑，也能夠有效降低噪音。第三種就是讓聲音在傳播過程中通過阻擋，過濾以及吸收等方法，將噪音逐漸降低甚至讓其停止傳播。</p><p style="text-indent:25px">雞蛋棉密度：密度越高，吸收低頻的能力越強。金字塔吸音海綿的高密度結(jié)構(gòu)，使其有了一個非常寬闊的吸收頻帶，50mm厚的金字塔吸音海綿吸收頻率可達到500HZ以上。用途：普遍應(yīng)用于錄音棚、錄音室、影音室、視聽室、ktv、隔音室、會議廳、演播廳、播音室、影劇院等場合的內(nèi)部裝飾。安裝：可直接刷膠水粘貼于墻壁或其它材料表面。加些創(chuàng)意、花點心思，營造一個溫馨家：加些創(chuàng)意、花點心思，營造一個溫馨家。梯度吸音棉屬層壓階梯密度多孔的吸音材料,吸聲機理是材料內(nèi)部有大量微小的連通的孔隙，聲波沿著這些孔隙可以深入材料內(nèi)部，與材料發(fā)生摩擦將聲能轉(zhuǎn)化為熱能。普通多孔吸聲材料的吸聲特性是隨著頻率的增高吸聲系數(shù)逐漸增大，這意味著低頻吸收沒有高頻吸收好。多孔材料吸聲的必要條件是：材料有大量空隙，空隙之間互相連通，孔隙深入材料內(nèi)部。波浪棉吸音原理：具有大量內(nèi)外聯(lián)通的孔隙和氣泡。</p><div

style="text-indent:25px">雞蛋棉吸音原理:具有大量內(nèi)外聯(lián)通的孔隙和氣泡，當聲波入射到其中時，可引起空隙中空氣振動;由于空氣的粘滯阻力，空氣與孔壁的摩擦，使相當一部分聲能轉(zhuǎn)化成熱能而被消耗。此外，當空氣絕熱壓縮時，空氣與孔壁之間不斷發(fā)生熱交換，由于熱傳導作用，也會使一部分聲能轉(zhuǎn)化成熱能。從而達到對聲音的緩沖還有吸音的效果，吸音的效果跟開孔的大小還有整張棉的厚度有著重要的關(guān)系，太薄的話即使能吸音也只能吸一小部分，另外開孔不適而開過大，過大就會沒有吸音效果，過小助力太大聲音過不去，在這方面做工適宜即可，吸音棉即可吸音也可以起到一些隔音效果，因為在聲音經(jīng)過吸音的時候會跟吸音棉產(chǎn)生摩擦，會把原有聲音的動作緩沖了一下，會減低原有聲音的穿透力，從而對隔音來說還是有輔助效果的，但隔音還得用專業(yè)的隔音棉較為理想。吸音棉種類：金字塔吸音棉、雞蛋棉、蘑菇棉。天津吸音雞蛋棉供應(yīng)</p><p

style="text-indent:25px">雞蛋棉又名波浪棉、波峰棉。是吸音棉中的一種。雞蛋棉是經(jīng)過設(shè)備特殊處理形成一面凸凹波浪形的一種海棉，其內(nèi)部充滿細小空隙及半開孔結(jié)構(gòu)能大量吸收射入的聲波能量對聲波起到衰減作用，降低室內(nèi)反射聲的干擾和回響，提高聲音的純度，是吸音降澡材料的高性能產(chǎn)品。雞蛋棉的分類：防火于不防火：雞蛋棉又分為防火雞蛋棉和不防火雞蛋棉。防火雞蛋棉是添加了助燃劑，助燃的標準是離火即息的效果。顏色分類:防火雞蛋棉一般會有黑色和白色，不防火的雞蛋棉可做成多種顏色，有粉紅色、黃色、藍色、黑色和白色。厚度和密度：雞蛋棉的厚度常規(guī)說法是兩張波峰重合后的厚度，單張的厚度一般會是商家所說的雙張厚度的4分之3厚度。隨著雞蛋棉的吸音厚度和密度的變化，雞蛋棉的吸音效果與雞蛋棉的厚度和密度成正比。選擇密度的時候可根據(jù)實際用途選擇厚度。天津吸音雞蛋棉供應(yīng)</p></p><br
