Sound insulation elastic layer
By using a three-dimensional fiber network sound-insulating elastic layer in the building floor structure, the problem of traditional materials being ineffective in reducing the propagation of impact noise is solved, providing a lightweight, easy-to-carry, and biodegradable sound insulation solution that significantly improves the impact sound insulation performance of the floor structure.

AI Technical Summary
Existing building materials are not effective in reducing the propagation of impact noise, especially impact noise propagated through the floor structure, and traditional materials are not environmentally friendly.
A sound-absorbing elastic layer employing a three-dimensional fiber network, using fibrous cellulose and/or wood cellulose materials, with a thickness of 1 to 120 mm and a dynamic stiffness of less than 200 MN/m3, is used between load-bearing floors and walkable floor coverings or floating floor layers to provide effective impact sound insulation.
It achieves lightweight, easy-to-carry, and biodegradable sound insulation, significantly improving the impact sound insulation performance of the floor structure and reducing noise transmission.
