3.1 Full and reduced-order models for deterministic vibro-acoustic calculations

We're concerned here with a deterministic vibroacoustic calculation: in the general case, we take into account the joint effects of dissipative and radiative damping. The vibroacoustic equation remains of the form (1) , where the matrix A(ω) depends only on frequency, and is expressed as :
