Patent Name: Sound Gate Composite Structure; Patent No.: 200920279477.2
This sound insulation and absorption door adopts a double-door composite structure of sound gate, with two inner and outer doors working together to form an acoustic isolation barrier. The outer door is formed by stamping painted cold-rolled steel plates, and its interior is densely filled with professional sound absorption materials, which can effectively reduce noise transmission. The inner door has a special-shaped structure, made by stamping and welding cold-rolled steel plates, and is externally equipped with sound absorption wedges to further enhance the absorption effect of high-frequency noise.
Due to its special structure different from ordinary doors, this door has better surface density and thickness than ordinary doors, and has strict requirements for sealing performance. The quality of hardware accessories and sealing parts is directly related to the sealing effect of the door. Relying on high-quality material selection and exclusive technical processes, Danpin ensures that this sound insulation and absorption door has excellent acoustic performance and a long service life. It can be widely used in scenarios with high sound insulation requirements, such as recording studios, acoustic laboratories, and industrial noise reduction sites, building a reliable acoustic environment protection system for acoustic spaces.
