Spectral element method (SEM) was applied to develop a latest method for structural intensity measurement. Structural intensity distribution can be more accurately obtained with a relatively small number of measurement points by combining SEM and actual measurement. The validation of the proposed method was examined by numerical simulations performed on a plate structure under the assumption of far field. In the simulation using finite element method (FEM), a finite element model was used as a reference structure and the proposed method worked well to compute the structural intensity within a small error.
