抗消声器

是由变界面的(de)(de)(de)(de)管和室(shi)合而(er)的(de)(de)(de)(de)，象是个(ge)(ge)声(sheng)(sheng)学(xue)(xue)滤(lv)(lv)(lv)(lv)(lv)波器(qi)，与(yu)电(dian)(dian)学(xue)(xue)滤(lv)(lv)(lv)(lv)(lv)波器(qi)相似(si)，每个(ge)(ge)带管的(de)(de)(de)(de)小室(shi)是滤(lv)(lv)(lv)(lv)(lv)波器(qi)的(de)(de)(de)(de)个(ge)(ge)网(wang)(wang)孔(kong)(kong)，管的(de)(de)(de)(de)空气相当于(yu)电(dian)(dian)学(xue)(xue)上(shang)的(de)(de)(de)(de)电(dian)(dian)和电(dian)(dian)阻(zu)(zu)，称(cheng)为(wei)声(sheng)(sheng)和声(sheng)(sheng)阻(zu)(zu)。小室(shi)的(de)(de)(de)(de)空气体(ti)积相当于(yu)电(dian)(dian)学(xue)(xue)上(shang)的(de)(de)(de)(de)电(dian)(dian)容，称(cheng)为(wei)声(sheng)(sheng)顺。与(yu)电(dian)(dian)学(xue)(xue)滤(lv)(lv)(lv)(lv)(lv)波器(qi)类(lei)似(si)，每个(ge)(ge)带管的(de)(de)(de)(de)小室(shi)都有(you)(you)自己(ji)的(de)(de)(de)(de)固有(you)(you)频率(lv)(lv)。当包(bao)含有(you)(you)各(ge)种频率(lv)(lv)分的(de)(de)(de)(de)声(sheng)(sheng)波进(jin)入个(ge)(ge)短管时，只有(you)(you)在(zai)(zai)个(ge)(ge)网(wang)(wang)孔(kong)(kong)固有(you)(you)频率(lv)(lv)附近的(de)(de)(de)(de)某(mou)些(xie)频率(lv)(lv)的(de)(de)(de)(de)声(sheng)(sheng)波才能(neng)通过网(wang)(wang)孔(kong)(kong)到达(da)二个(ge)(ge)短管口，而(er)另外些(xie)频率(lv)(lv)的(de)(de)(de)(de)声(sheng)(sheng)波则遥遥能(neng)通过网(wang)(wang)孔(kong)(kong)．只能(neng)在(zai)(zai)小室(shi)来回反射，因(yin)此，我们称(cheng)这种对声(sheng)(sheng)波有(you)(you)滤(lv)(lv)(lv)(lv)(lv)波功能(neng)的(de)(de)(de)(de)结(jie)为(wei)声(sheng)(sheng)学(xue)(xue)滤(lv)(lv)(lv)(lv)(lv)波器(qi)。选取适(shi)当的(de)(de)(de)(de)管和室(shi)进(jin)行(xing)合．就可以滤(lv)(lv)(lv)(lv)(lv)掉(diao)某(mou)些(xie)频率(lv)(lv)分的(de)(de)(de)(de)噪声(sheng)(sheng)，从而(er)达(da)到消(xiao)声(sheng)(sheng)的(de)(de)(de)(de)目的(de)(de)(de)(de)。抗消(xiao)声(sheng)(sheng)器(qi)适(shi)用于(yu)消(xiao)除(chu)、低频噪声(sheng)(sheng)。

阻抗复合式消声器

由(you)阻(zu)结和抗结按照的方(fang)式合。

微穿孔板消声器

般(ban)是用(yong)厚(hou)度小于1mm的(de)纯金属(shu)薄板(ban)制作，在薄板(ban)上用(yong)孔径小于1mm的(de)钻头穿(chuan)孔，穿(chuan)孔率为1%3%。选择不同的(de)穿(chuan)孔率和板(ban)厚(hou)不同的(de)腔，就(jiu)可以控制消(xiao)声器的(de)频(pin)谱能，使其在需要的(de)频(pin)率范围内得良的(de)消(xiao)遥(yao)遥(yao)。

小孔消声器

结是(shi)根末端封闭的直管(guan)，管(guan)壁(bi)上钻有(you)很小(xiao)(xiao)(xiao)孔。小(xiao)(xiao)(xiao)孔消(xiao)声器(qi)的原理(li)是(shi)以(yi)喷气(qi)噪声的频(pin)谱为依据的，如果保持(chi)喷口(kou)(kou)的总面(mian)积不变而(er)用很小(xiao)(xiao)(xiao)喷口(kou)(kou)来代替，当气(qi)流经(jing)过小(xiao)(xiao)(xiao)孔时、喷气(qi)噪声的频(pin)谱就会移向频(pin)或(huo)频(pin)，使频(pin)谱的可听声分明降低(di)，从而(er)减少(shao)对人的干扰(rao)和伤害。

有消声器

基本原理是在(zai)原来的(de)(de)声场，利用电子设(she)备再产生个(ge)与原来的(de)(de)声压(ya)小相(xiang)等、相(xiang)位(wei)相(xiang)反的(de)(de)声波，使(shi)其在(zai)范围内与原来的(de)(de)声场相(xiang)抵消。这种消声器是套仪器装置，要由声器、放器、相(xiang)移装置、功(gong)率放器和扬声器等。

消声器的衡量指标

衡量消声(sheng)(sheng)器的(de)(de)坏，要考虑以下(xia)三个方面： 1、消声(sheng)(sheng)器的(de)(de)消能(neng)；（消量和频谱） 2、消声(sheng)(sheng)器的(de)(de)空气动力(li)能(neng)；（压(ya)力(li)损失等） 3、消声(sheng)(sheng)器的(de)(de)结(jie)能(neng)。（尺寸、格、等）
