Physically Informed Sonic Modeling (PhISM)
PhISEM Particle Models
Stochastic Resonances in PhISEM
The PhISEM approach can also be applied to systems, such as the tambourine and sleighbells, that produce a somewhat random distribution of resonances around a set of center frequencies.
The same event and system energy decay behaviors apply, though the implemented resonance frequencies are randomly varied with each collision event.
The tambourine model uses two resonances for the cymbals and one weak resonance for the wooden frame.
The sleighbell model uses five resonant filters.
Other objects that can be simulated in this way include bamboo wind chimes and coin interactions with a mug.
Water drop sounds can also be synthesized with this model by modifying the resonant frequency during each drop event (upward sweeping trajectories).
