The floor pavement and the floor structure layer are completely elastic isolation, no firm connection exists, and the floor pavement has good isolation effect on solid sound and air sound between the upper floor layer and the lower floor layer. Most of existing floating floors adopt simple damping blocks to damp the floating floors, but the damping effect of the damping mode only through the damping blocks is not ideal, so that special dampers can be used for noise reduction and damping of the floating floors in certain special occasions.
