style="text-indent:25px">汽車的排氣消聲器是行車噪聲處理的主要組成部分，排氣消聲器的主要是通過減低、衰減排氣壓力的脈動來消除噪聲的。吸收式消聲器：通過廢氣在玻璃纖維、鋼纖維和石棉等吸音材料商的摩擦而減少其能量；反射式消聲器：有多個串聯(lián)的協(xié)調(diào)腔與不同長度的多孔反射管相互連接在一起，廢氣再其中經(jīng)過多次的反射、碰撞、膨脹、冷卻而降低其壓力，減輕震動及能量。汽車上多是綜合利用不同的消聲原理組合來設(shè)計排氣消聲器，同時在舒適型要求較高的小型乘用車上還會采用多個消聲器單元進(jìn)行多級的消聲降噪控制。</p><p style="text-indent:25px">一般采用靜態(tài)消聲量來表示消聲器的消聲效果，因為靜態(tài)消聲量是一個定值，而動態(tài)消聲量受氣流速度的影響，是一個不定值，故評價指標(biāo)以用靜態(tài)消聲量為宜。當(dāng)聲源經(jīng)靜態(tài)消聲后的剩余聲級（簡稱靜態(tài)出口聲級）大于消聲器氣流噪聲級時，消聲器的動態(tài)、靜態(tài)消聲量基本一致，不受氣流的影響；當(dāng)消聲器靜態(tài)出口聲級低于消聲器氣流噪聲級時，則消聲器的動態(tài)消聲量低于靜態(tài)消聲量，其差值隨流速的增加而增大；當(dāng)氣流噪聲級大于消聲器入口聲級時，此時消聲器不僅不能消聲，反而變成了一個噪聲放大器。為解決靜態(tài)和動態(tài)消聲量可能不一致的問題，有些消聲器產(chǎn)品已采用靜態(tài)消聲量和氣流噪聲級兩個指標(biāo)同時表示產(chǎn)品的聲學(xué)性能。風(fēng)機消聲器分為：離心風(fēng)機消聲器、羅茨風(fēng)機消聲器、鼓風(fēng)機消聲器、軸流風(fēng)機消聲器。</p><div

style="text-indent:25px">汽車排氣管里的消聲器的原理：就是通過降低、衰減排氣壓力的脈動來消除噪聲。根據(jù)干涉原理，排氣消聲器有吸收、反射兩種基本的消聲方式。吸收式消聲器，通過廢氣在玻璃纖維、鋼纖維和石棉等吸音材料上的摩擦而減小其能量；反射式消聲器則有多個串聯(lián)的諧調(diào)腔與不同長度的多孔反射管相互連接在一起，廢氣在其中經(jīng)過多次的反射、碰撞、膨脹、冷卻而降低其壓力，減輕振動及能量。實際情況下，汽車上多是綜合利用不同的消聲原理組合來設(shè)計排氣消聲器，同時在舒適型要求較高的小型乘用車上還會采用多個消聲器單元進(jìn)行多級的消聲降噪控制。江門消聲器有哪些</p><p
