Abstract
These notes correspond to two lectures given by Bruno Cochelin at the CISM course on “Modal Analysis of Nonlinear Mechanical Systems” held at Udine, from 25 to 29 june 2012. The first part is devoted to describe experimental results obtained by Romain Bellet to analyse Target Energy Transfer (T.E.T.) between a thin visco-elastic membrane and an acoustic medium. This study paves the way for a new technic of passive sound control in the low frequency regime, where no effective dissipative material exists. Then, an overview of several extentions and applications of the T.E.T. concept in acoustics is given. All these results have been obtained with the collaboration of R. Bellet, S. Bellizzi, R. Côte, P. Herzog, R. Mariani., P.O. Mattei and J. Shao.
