There are many theoretical studies on sound insulation structure, but there is little practice about it, the quality of the project is easy to appear, and it is not worth the loss, so the sound insulation structure can not be implemented in a large area of the building.<br><br>Raw material detection and impact sound insulation performance detection were carried out, the construction quality was observed, through the application of 10mm thick high-performance sound insulation mortar blank and decoration completed two states of comparative study.<br><br>The results show that the sound insulation structure is good for improving the acoustic acoustic insulation performance of the floor, and has the advantages of simple implementation, does not affect the net height of the floor, the quality of the project is easy to control.<br>Green buildings; floor sound insulation; high-performance soundproof mortar; sound-proof flooring.
