The shortcomings can be found in several kinds of floor impact sound insulation structures of civil buildings. There are many theoretical studies on the sound insulation structure, but few on its practice. The engineering quality problems are prone to occur, and the gains outweigh the losses. Therefore, the sound insulation structure has not been widely implemented in the building. The raw material test and impact sound insulation performance test were carried out, and the construction quality was observed via the comparative study of the two states of the application of 10mm thick high-performance sound insulation mortar blank and the completion of decoration. The results show that the sound insulation structure has good effect on improving the impact sound insulation performance of floor, and has the characteristics of simple implementation, no impact on the floor height, and easy control of the engineering quality.
