[0002] Noise pollution, air pollution and water pollution are known as the three major pollutions in the world. With the development of social economy, people's requirements for quality of life are increasing day by day, and the problem of noise pollution has also attracted widespread attention from the society. Especially for some high-noise technology residences, production plants, laboratories, equipment rooms and other places, sound insulation facilities are particularly important.

[0003] The promulgation of the "2022 Noise Law" has given people a further understanding of the sound environment in which they live and a sense of rights protection, which has led to the strengthening of noise weaknesses by various developers. As for the problem of holes through the wall, many developers have considered and implemented many details, ignoring the problem of noise. The existing pipe hole through the wall plugging structure usually uses a single-layer sound insulation board to achieve noise reduction, and its noise reduction effect is very poor. In summary, hole leakage has always been a difficult problem to solve. Utility Model Content
