style="text-indent:25px">直管消聲器消聲量的計算:直管式消聲器消聲量主要與通道形式、長度和吸聲材料的性能有關。消聲量的計算公式為：其中，Φ是消聲系數(shù)，即每米消聲量(dB/m)；P是消聲器通道截面周長(m)；S是消聲器通道截面積(m2)。消聲管道內(nèi)吸聲系數(shù)越大，消聲系數(shù)Φ越大，消聲量越高。增加長度，或增加通道周長與截面積的比P/S，消聲量越大。同樣周長，圓形截面的周長與截面積的比，要比扁狀的矩形小很多，因此，圓形截面的直管式消聲器消聲性能小。當直管消聲器截面較大時，如徑尺寸大于30cm的圓管或矩形管，高頻聲波成上束狀，將直接穿過管道，而與管壁的吸聲材料不發(fā)生作用，消聲性能變差，這種高頻性能下降的現(xiàn)象被稱為“高頻失效”。并將高頻消聲量明顯下降的頻率稱為“上限失效頻率”。</p><p style="text-indent:25px">消聲器的工作原理主要是讓推動彈丸做功的燃氣在一個相對于管要大得多的封閉空間內(nèi)釋放熱能，以減少壓強和流速，避免對口附近的空氣產(chǎn)生過大的沖擊（也就是產(chǎn)生口噪音——發(fā)射時的主要噪音）?，F(xiàn)在世界上通用的消音器其原理基本上是通過降低燃氣沖出口的速度和流量來降低較大峰值來消音。具體的措施是，在消音器內(nèi)裝上若干帶有小孔的消音隔板或鋼絲，或在口安裝一個口徑比小的橡膠消音器等等來降低口的較大峰值（也就是提前將燃氣要做的功傾瀉掉），同時使用低于音速的彈（低速彈）降低在空氣中飛行的呼嘯聲。不管你用什么方法來降低的聲音，總是要**的一些性能，同時使自動機工作不正常。所以消音器并沒有什么制退的作用，也不會減小后坐力?，F(xiàn)在的一般在膛口處加裝了籠型或桶型消焰器，通過改變排焰孔的切削角度可以實現(xiàn)一定的制退作用，但是裝上消音器后膛口裝置的制退作用也消失了。消音器除了通常的消音和消焰作用外，還有一個附加的好處——在膛口處增加了一個重物，可以抑止口上跳，減少散布提高精度。蒸汽消聲器采用多級消聲，消聲量大，排汽消聲器可達35～40分貝。</p><div
