摘要：
A study on the optimization of sound transmission loss (TL) across a double-walled cylindrical laminated composite shell whose walls sandwich a layer of porous material is investigated using a genetic algorithm. First, an exact relation is presented by considering the effective wave component in the porous layer within the framework of the classic theory for laminated composite shells. The TL of the structure is estimated in a broadband frequency. Then, an acoustic optimization is considered for the sandwich structure with respect to the constraints of geometric properties.
