Interactive Simulation of rigid body interaction with friction-induced sound generation

Abstract

Abstract-Acoustic simulation of friction is a particularly challenging task, because continuous (strong) contact conditions require a tight and veridical integration of the synthesis layer with the control input. This paper presents an algorithmic realization that combines recently proposed physical models of friction with the lumped modal description of resonating bodies. It is shown that the resulting nonlinear dynamical system can be discretized using a numerical technique that allows efficient and accurate simulation. Applications in the context of interactive audio-visual animation on low-cost general-purpose computers are demonstrated, and an approach to joint audio-visual synthesis is proposed that provides fine-scale synchronization and high coherence between the two modalities. The interactive animations show that the model is successful in reproducing several salient everyday sound phenomena, such as rubbing, braking, and squeaky doors.

Preliminary Experiment Combining Virtual Reality Haptic Shoes and Audio Synthesis

“…This model and its discretization is described elsewhere in detail [3]. The model has been recently adapted to the audio simulation of footsteps [18].…”

Robust prediction of auditory step feedback for forward walking

“…Physically-based sound synthesis is an independent topic and a number of models were already presented, for example in [Avanzini et al 2005] where a model has been presented which has previously been used to create synthetic step sounds [Turchet et al 2010]. …”

Eluding the Physical Constraints in a Nonlinear Interaction Sound Synthesis Model for Gesture Guidance

“…Today friction phenomena are still debated and several mechanisms are under investigation, such as the conversion process from kinetic to thermal energy provoked by friction at the atomic scale [2]. In spite of the physical complexity of friction phenomena, physically inspired friction models have been developed within various domains [3,4]. Such models have for instance been used for musical purposes in the case of simulations of sounds from bowed string instruments intended for electronic cellos or violins [5] or unusual friction driven instruments based on both physical and signal models [6].…”

“…All these models strongly depend on physical considerations and require the control of specific physical parameters. For example in the model proposed by Avanzini et al [3] seven physical parameters must be defined to synthesize a friction sound. Although these parameters well characterize the physical behavior of the friction phenomenon, they are not at all intuitive for naive users.…”
