摘要： Provided is a composite structure for noise insulation and a multiple composite sheet including the same. The composite structure may include a first sheet layer including first hexagonal cells forming a hexagonal pattern, an elastic film layer laminated on the first sheet layer and including polymers, and a second sheet layer laminated on the elastic film layer and including second hexagonal cells forming a hexagonal pattern. The first hexagonal cell has a center at which a point where vertices of a plurality of second hexagonal cells are joined is located.

摘要： A sound insulation plate includes a patterned frame and an elastic membrane, wherein the patterned frame includes a central pattern region and multiple peripheral pattern regions arranged around the central pattern region, the multiple peripheral pattern regions being separated from the central pattern region by a separation bar, and wherein the elastic membrane is mounted on the patterned frame to block passage of air and converts airborne sound waves into elastic waves.
