在减振降噪治理工程中应用二次隔振降低固体传声，可以达到较理想的效果。二次隔振系统固有频率低，有利于隔绝低频振动。对屋面柜式风机进行了二次隔振，选择合适的质量比、刚度比，避开共振，同时与一次隔振进行了比较分析。

Two-stage vibration isolation is applied to reduce solid sound transmission on noise control engineering, the effect is ideal . The natural frequency of two-stage vibration isolation is low , which is conducive to isolate low-frequency vibration. The technology of two-stage vibration isolation is used on roof tank fan. The appropriate mass ratio and stiffness ratio are chosen, the resonance is avoided. It is compared with one-stage vibration isolation.
