In order to create an immersive virtual world, it is crucial to incorporate a realistic aural experience that complements the visual sense. Physically-based sound simulation is a method to achieve this goal and automatically provides audio-visual correspondence. It simulates the physical process of sound the pressure variations of a medium originated from some vibrating surface sound synthesis, propagating as waves in space and reaching human ears sound propagation. The perceived realism of simulated sounds depends on the accuracy of the computation methods and the computational resource available, and often times it is not feasible to use the most accurate technique for all simulation targets. I propose techniques that model the general sense of sounds and their details separately and adaptively to balance the realism and computational costs of sound simulations.
