Abstract

A multi-layer low-frequency broadband membrane-type acoustic metamaterial sound isolator were investigated. It is a multi-layer “plate-membrane-plate-membrane-plate” structure composed of light round whole plate and elastic rubber membrane. By simulation analysis towards single layer and multi-layer structure as well as different parameters that affect multi-layer structure, the corresponding acoustic insulation index of each frequency band was obtained. By comparison of the acoustic insulation curves under different circumstances, the acoustic insulation properties under different circumstances can be obtained by direct-view. The results of simulation analysis can enrich the research of multilayered metamaterials to a certain extent.
