The sound environment problem of residential buildings becomes the problem that the sound environment problem of the residential buildings needs to be fully paid attention and considered in the current urban planning, the community design and the single body design of the residential buildings, the people-oriented problem is really reflected, and the people strive to create a beautiful and comfortable living environment for the residential buildings.

In particular, indoor household panels are important tools for rapidly fulfilling the needs of personal spaces in an efficient space, and it is obvious that the sound insulation performance of indoor household panels is a key performance of the core thereof. However, most of the existing indoor panels are simple and easy, and have no consideration on sound insulation performance, and if the consideration on sound insulation performance exists, the panels need to be arranged more cumbersome, which is not favorable for the convenience and rapidity of installation of the indoor panels. For example, the invention patent with the publication number of CN103334507A discloses a sound absorption and insulation type building board, which comprises at least one layer of sound insulation board and at least one layer of sound absorption board which are compounded together, wherein the sound insulation board is mainly formed by mixing cement, perlite powder, calcium sulfate particles, calcium silicate particles and water to prepare mortar and then solidifying and hardening the mortar; the sound absorption board is mainly formed by mixing cement, magnesium silicate particles, ceramsite, calcium sulfate particles and water to prepare mortar, and then solidifying and hardening the mortar. The proposed panel, although alleviating the sound insulation problem, is heavy and not suitable for indoor use.

To this technical current situation, simultaneously based on this application utility model discloses the people is in building materials field sound insulation field be absorbed in research and development experience and accumulated theoretical knowledge, verifies through a large amount of practical application cases simultaneously, finally proposes this application technical scheme and improves above-mentioned technical problem.
