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。深圳消聲器哪家靠譜消聲器一般應(yīng)設(shè)于空調(diào)機房和空調(diào)房間之間考近空調(diào)機房，且氣流穩(wěn)定的直管段上。</p><div
