Développement de panneaux hybrides passifs/actifs pour l'acoustique

Abstract : Passive structures such as double walls are effective at reducing noise transmission at medium and high frequencies. They are widely used in building and transport applications. In this thesis, a hybrid passive/active acoustic panel concept is developped, with the aim of allowing high levels of absorption and insulation over a wide range of frecuencies. The secondary source is realized by an active plate consiting of two piezoelectric patches bonded to an elastic thin plate. The use of porous material as the core of the double-panel improves the acoustic efficiency of the structure. Numerical and experimental results show that this structure presents good absorption and transmission properties thanks to active control.
