“…To predict such structure-borne sound transmission, for example, the energy-based method such as the statistical energy analysis method [1] has been applied to aerospace engineering [2], investigations of structure-borne sound on ships [3,4], and architecture [5]. The method is also applied to a practical case study on the prediction of structureborne sound in a building [6] by Craik et al In contrast, numerical techniques, such as the finite element method (hereafter called FEM), boundary element method, and finite difference method, have been also applied to prediction of the wave motion in the sound and vibration fields.…”
