此种复合式消声器的抗性消声是由内管截面的突变（不连续）及内外管之间的膨胀室（1#4#为三室串联，5#10#为二室串联）作用所构成，而阻性消声则由超细玻璃棉吸声片吸收声能以降低噪声。

T701-6型消声器系列的单位长度消声量一般为：

低频10-15dB/m，中频15-20dB/m，高频20-25dB/m，单级压力损失15-60Pa。

1.选用消声器的风速6-10m/s为宜，最高12-14m/s.2.1-4号可单级使用，5-10号应多节串联。

1.3.消声器可直接安装于风机出风口，在系统中尽量安装在靠近空调机房，消声器外壳应与风管同样作保温处理。

4.目前由于该消声器体积较大逐渐由前面的几种系列所替代。

1.所需的倍频程和A声级的消声量是否能满足设计要求，当离设计要求还有较大差距或一定差距时，可以在消声器有效长度中间再加一节或二节1000mm长的消声器，以提高消声量和达到设计要求。

2.片式消声器的断面和长度是否有足够安装空间，当高度不够宽度有余时可换断面尺寸，向宽度扩展.ZKS，ZKSA型折板式消声器ZKS型折板式消声器消声性能以中高频为主，消声量及压力损失大于片式消声器，长度为900mm。

在ZKS型折板式消声器外壳加隔声处理后，即为ZKSA型，其消声性能与压力损失和ZKS型折板式消声器相同。

当消声器设在机房或噪声较高的房间时宜采用ZKSA型折板式消声器。
