Sound Simulation for Object Collisions in Virtual Environments

Abstract

we proposed methods for sound simulation during collisions of virtual objects in virtual environments. The approach is based on the playback of pre-recorded audio signals triggered by collision events, as well as by sliding and rolling friction between objects. We generated sound samples for each pair of interacting object types using the Audacity audio editor. We implemented sound rendering with the open-source Miniaudio library to support 3D audio in a virtual environment. During simulation, sound volume depends on parameters obtained from collision detection and collision response. We computed sound amplitude during impacts using a harmonic oscillator model. We tested the proposed methods in the VirSim virtual environment software package using interactions between a virtual robot and various objects, as well as object-object interactions. The results show that the approach provides consistent and realistic audio feedback for collision and friction events.
