description The utility model discloses a cylindrical cavity structure sound barrier plate capable of improving the sound absorption effect, and relates to the technical field of noise treatment equipment. A non-metal acoustic board; and a cavity structure. According to the composite non-metal sound barrier plate, the connecting part of the non-metal sound absorption plate and the concrete main body sound insulation plate is arranged to be of the cavity structure, so that the air cavity is formed in the cavity structure, the air cavity and the sound absorption component resonate, and a sound absorption structure different from a conventional composite non-metal sound barrier plate is formed; in the process of transmitting sound waves, the purpose of improving the sound absorption effect is achieved through friction heat loss energy generated by resonance; meanwhile, due to the fact that the back face of the non-metal sound absorption plate is pressed into the cavity structure, part of non-metal composite materials are sa
