导读：复合阻抗消声器安装位置，阻抗复合消声器是指将声吸收和声反射恰当地组合起来的消声器。

阻抗复合消声器是指将声吸收和声反射恰当地组合起来的消声器。它同时既有阻-消声器消除-、高频噪声和抗-消声器消除低、-频噪声的--，具有宽频带的消声-果。
1. 阻抗复合式消声器就是把对高、-频噪声消声-果--的阻-消声器及对-、低频噪声消声-果--的抗-消声器组合-成。由于声波的波长比较长，阻-和抗-消声器复合在-起时有声的耦合作用，互相有影响，不能看作简单的叠加关系。
2. 由于消声器的组合型式较-，阻抗复合式消声器的-种也较-，但定型产-都是按原-家标准图制造。
3. 因为消声-果-，频谱--宽，在通风空调工程-普遍应用。但和阻-消声器-样，不能用于有蒸汽侵蚀或高温的场合。
