No metal material in the barrier, Absorption layer is made of polymeric particles material.Insulation layer is made of particle material, reinforced cement fiberboard and non-metallic materials such as reinforced cement fiberboard and glass magnesium board. Absorption layer and insulation layer are compounded by all structural adhesive.
High, medium and low frequency sound absorption features of particulate sound absorption materials are closely related to the size and quantity of tiny pores between particles, structure form, thickness of plate, size of cavity behind plate, etc. Sound absorption frequency features can be adjusted by regulating the particle size, plate thickness and cavity size to meet the high, medium and low frequency sound absorption requirements. In the practical engineering, the targeted design and selection of particulate materials (structure) in acoordance with acoustic design requirements will get twice the result with half the effort;
