Sammanfattning
This master thesis has been done in collaboration with the IRCAM (Institute for Research and Coordination of Acoustics and Music), the IJLRDA (Jean le Rond D’Alembert’s Institute), Chalmers University of Technology and the ENS (Ecole Normale Supérieure) de Cachan. In this study, modal active control will be applied to musical instruments: a simplified string instrument, a guitar and finally a simplified wind instruments. It will be showed that the control of damping and/or frequency of the modes of the instruments can be done, leading to local modifications of their vibrations of decades of dB´s. Moreover, a synthesis of guitar pluck will be done and used for a comparison study with experimental results.
