Modeling and simulation of musical instruments: propagation, dissipation and coupling.
Musical instruments are complex objects that involve various physical phenomena, coupled together and sometimes non-linear. The instrumental practice exerts a very fine control on these systems in order to obtain a variety of possible responses, all in a musical contexts, thus constrained. Research in musical acoustics aims at understanding the behaviour of these objects with a level of precision comparable to that deployed by the musician in his playing. This is done through comparison with experimental measurements in different regimes but also through sound synthesis. This talk will focus on wind instruments and will present the main lines of their modeling and simulation, especially with regard to the consideration of visco-thermal phenomena responsible for part of the energy dissipation in the instrument.
