[0002] In recent years, the real estate industry in China has developed rapidly, but many problems have also emerged, such as the problem of residential sound insulation. To address these problems, many solutions have been adopted, such as using sound-insulating windows for building exterior windows, using heavy structures or high-sound-insulation-performance structures for分户墙, and laying vibration damping pads on分户楼板. Objectively, these methods have reduced the impact of living noise and achieved certain sound insulation and noise reduction effects.

[0003] However, acoustic design is different from visual design. For visible designs, people can directly feel the effect differences. It is difficult for people to immediately feel the design effect in acoustic design. This is why many people only discover various noise problems after living in a house for a period of time, complain to the property management, and then it takes several times the cost to solve the noise problem. Therefore, a display venue is needed that can allow people to directly experience the residential sound insulation design, not only can simulate the real living experience, but also can compare the effect differences of several different sound insulation schemes, so that users can have a direct experience of the sound insulation effect of the room before moving in.
