Aerospace vehicles are subject to broadband, sometimes severe, vibroacoustic and structure-borne excitations of various origin, which can danger the availment of the payload on board and the electronic equipment, and consequently the unsuccess of the entire mission. It is therefore important for the modern industry the development of analytical and numerical tools that can accurately predict the vibroacoustic response within structures of various geometries and subject to a combination of vibroacoustic excitations in order to mitigate unwanted phenomena able to compromise the whole mission. Nowadays, A lot of research has been conducted on the correctly modelling of wave propagation characteristics within representing the reactivity of the structure in noise field.
