Mental Damping Sound Insulation panel

The front and back panels are made of inorganic materials with different densities and thicknesses, the core layer is a soft aluminum metal plate, and the double-layer polymer damping material is glue-free and high-pressure composite molding. The soft aluminum plate in the core layer has significant isolation properties for mid-high frequencies and ultra-high frequencies, and the high-density front and back panels have excellent mid- and low-frequency sound insulation effects. The double-layer damping constraint structure generates efficient low-frequency and ultra-low-frequency transmission of shear stress.
