Abstract: Abstract Finding the distribution of vibro-acoustic energy in complex built-up structures in the high frequency regime is a challenging task. At high frequencies exact numerical methods such as the boundary element method or the finite element method (FEM) are beginning to overstretch the capacity of even the most advanced computer architectures. Moreover, “numerically exact” results obtained by an FEM for a specific structure may be of little practical value. The vibro-acoustic response of “identical” structures assembled as part of a manufacturing process is very sensitive to small changes in material parameters or variability of the shape of the structure.
