Empirical physical modeling for bowed string instruments
The various components needed to define an empirical violin physical model are assembled and their interaction is detailed. We experimentally measure the mechanical admittance at the violin bridge using the impact hammer excitation method and the monopole radiativity in anechoic conditions. These are combined with a digital waveguide model computing the dynamical behavior of the bowed string. Theoretical bridge oscillations and sound radiation are defined by convolution of the bowed string physical model signals with impulse responses determined from experiment.
