A recently granted patent (Publication Number: US11866930B2) discloses a partition wall sound insulation structure designed to reduce sound transmission between spaces in a building. The structure includes a pair of face materials with a hollow portion in between, supported by first and second studs fixed to the inner surfaces. A sound insulation face material, thicker than the gap between the surfaces, is positioned to block the gap and has a higher surface density. A positioning member ensures proper alignment of the studs and face materials, with grooves for insertion of the studs. The structure can be customized with different sound insulation materials on the floor or ceiling surfaces, each with a unique coincidence frequency to enhance soundproofing capabilities.
Furthermore, the patent also introduces a sound insulation member for use in the structure, featuring a similar design with face materials, studs, and a sound insulation face material. The positioning member ensures precise alignment of the studs and face materials, with grooves for stud insertion. The sound insulation face material is thicker than the gap between surfaces and has a higher surface density, enhancing its soundproofing properties. This innovative structure aims to provide an effective solution for reducing sound transmission between spaces in buildings, offering customization options for different surfaces and frequencies to optimize sound insulation performance.
