Full validation of the structural-acoustic response of a simple enclosure

This paper is a review of the basic methodologies for the study of the vibr oacoustic problem of enclosed cavities, The assessment of these methodologi es Is addressed from the theoretical, numerical, and experimental point of view, A simple geometry has been selected as an intersection item for all t hree approaches, particularly for the theoretical solution. Complex geometr ies Increase the difficulties of solving the relative equations without add ing an increased value to the validity of the comparison of the three appro aches. The results validate the classical finite element and the experiment al approach for the vibroacoustic behavior of enclosed cavities with one el astic wall in the low modal density frequency region. As expected, a carefu l understanding of the numerical and experimental results turns out to be a very important task and an addressable topic for future investigations. Th is paper also outlines a useful comment about the aliasing effect of the wa velength discrete representation.
