帶您了解一下的定義

消聲器OPE电竞是指對于同時具有噪聲傳播的氣流管道,可以用附有吸聲襯里的管道及彎頭或利用截面積突然改變及其他聲阻抗不連續的管道等降噪器件,使管道內噪聲得到衰減或反射回去。前者稱為阻性消聲器,后者稱為抗性消聲器,也有阻抗復合式的消聲。

種類概述:消聲器種類很多,但究其消聲機理,又可以把它分為六種主要的類型,即阻性消聲器、抗性消聲器、阻抗復合式消聲器、微穿孔板消聲器、小孔消聲器和有源消聲器。

阻性式

主要是利用多孔吸聲材料來降低噪聲的。把吸聲材料固定在氣流通道的內壁上或按照一定方式在管道中排列,就構成了阻性消聲器。當聲波進入阻性消聲器時,一部分聲能在多孔材料的孔隙中摩擦而轉化成熱能耗散掉,使通過消聲器的聲波減弱。云南通風設備告訴您阻性消聲器就好象電學上的純電阻電路,吸聲材料類似于電阻。因此,人們就把這種消聲器稱為阻性消聲器。阻性消聲器對中高頻消聲效果好、對低頻消聲效果較差。

KANGXINGSHI

是由突變界面的管和室組合而成的,好像是一個聲學濾波器,與電學濾波器相似,每一個帶管的小室是濾波器的一個網孔,管中的空氣質量相當于電學上的電感和電阻,稱為聲質量和聲阻。小室中的空氣體積相當于電學上的電容,稱為聲順。與電學濾波器類似,每一個帶管的小室都有自己的固有頻率。當包含有各種頻率成分的聲波進入第一個短管時,只有在第一個網孔固有頻率附近的某些頻率的聲波才能通過網孔到達第二個短管口,而另外一些頻率的聲波則不可能通過網孔.只能在小室中來回反射,因此,我們稱這種對聲波有濾波功能的結構為聲學濾波器。選取適當的管和室進行組合.就可以濾掉某些頻率成分的噪聲,從而達到消聲的目的。抗性消聲器適用于消除中、低頻噪聲。

基本原理是在原來的聲場中,利用電子設備再產生一個與原來的聲壓大小相等、相位相反的聲波,使其在一定范圍內與原來的聲場相抵消。云南通風設備告訴您OPE电竞這種消聲器是一套儀器裝置,主要由傳聲器、放大器、相移裝置、功率放大器和揚聲器等組成。
