International audienceThis paper presents an advanced computational method for the prediction of the responses in the frequency domain of general linear dissipative structural-acoustic and uid-structure systems, in the low-and medium-frequency do¬mains, including uncertainty quantication. The system under consideration is constituted of a deformable dissipative structure, coupled with an internal dissipative acoustic uid including wall acoustic impedances and surrounded by an innite acoustic uid. An efcient reduced-order computational model is constructed using a nite element discretization for the structure and the internal acoustic uid. The external acoustic uid is treated using an appropriate boundary element method in the frequency domain. All the required modeling aspects for the analysis of the medium-frequency domain have been introduced namely, a viscoelastic behavior for the structure, an appropriate dissipative model for the internal acoustic uid including wall acoustic impedance and a model of uncertainty in particular for modeling errors. This advanced computational formulation, corresponding to new extensions and complements with respect to the state-of-the-art, is well adapted for developing new generation of software, in particular for parallel computers
