000014938 520__ $$2eng$$aLattice sandwich structure is a burgeoning multifunctional material since it is lightweight, designable, etc. It also has the potentialities in sound insulation, which is vital for the safety and stability of service, for its high porosity. In the paper, sound transmission characteristics of pyramidal truss core sandwich panel are investigated. The structure consists of two face-sheets and a core composed of trusses and sound absorbing material filling in the space. The structure is surrounded by acoustic fluid and an incident wave is imposed on the panel. Fluid—structure coupling is considered. The accurate periodic model with pyramidal truss cores repeating in two dimensions is established and analysed. Using the numerical calculation, the sound transmission characteristics of structure is studied. Finally, the effects of parameters of structure and incident wave are discussed for thorough understanding and system design.
