摘要：
In this paper, sound transmission between cavities through flexible panel are studied theoretically and experimentally. The coupled vibro-acoustic model is established based on an energy formulation, and the system matrix equation is obtained by Rayleigh-Ritz procedure. Numerical simulation is then performed, and the validation is carried out through the comparison with those from FEA. Relevant experimental studies are also performed, and the theoretical and experimental results are compared and analyzed. Some concluding remarks are also given.
