Generally, active or passive piezoelectric techniques are effective in the low frequency range, while dissipative materials, such as viscoelastic or porous treatments, are efficient for higher frequency domain. In this work, a reduced order model is developed for the resolution of a fully coupled electro-mechanical-acoustic system using modal projection techniques. The problem consists of an elastic structure with surfacemounted piezoelectric patches coupled with an inviscid and compressible fluid. The piezoelectric elements, connected with a resistive or resonant shunt circuit, are used for the vibration damping of the coupled system. Numerical examples are presented in order to illustrate the accuracy and the versatility of the proposed reduced order models,notably in terms of prediction of attenuation..
