Research on the acoustic performance optimization of green building floor

The green building puts forward higher requirements for the health, comfort and environment of the building, and the sound insulation performance of floor is the basic functional requirement, but it is often ignored in the practical design. As a construction component of separating space, the building slabs must be seriously considered in order to solve the sound insulation problem caused by floor impact. Based on reinforced concrete residential floor, by taking into account the relevant factors such as resilient material type, thickness, mass density, dynamic stiffness and the quality and thickness of floating slab, different series of floating floor structure are developed. The theoretical analysis and experimental study on the sound insulation performance of different floating floor structures are carried out in this paper, and the results can provide technical support and case experience for the noise reduction design of building floor, and have positive significance for optimizing and improving the sound insulation performance of buildings.
