The coupled finite element/boundary element method is developed to simulate sound transmission through elastic shell. The vibration of the thin elastic shell is simulated using the finite element method and the acoustic fields both inside and outside the elastic shell are simulated using the boundary element method. To avoid the nonuniqueness problem occurring in the exterior boundary element method, the Burton and Miller formulation is applied. The algorithm is validated using the simulation of a fluid-filled submerged elastic spherical shell excited by a point sound source located at the center.
