Ease audio simulation9/17/2023 The wavelengths of these waves - the wavelengths of the visible spectrum - will generally be many times smaller than any surface in the scene being rendered, so wave phenomena have little or no visible effect. The technique works well for simulating light because of the relatively high frequencies of the modelled waves. ![]() The modelling of waves as particles has found great success in the field of computer graphics, where ray-tracing is used to simulate the reflections of light in a scene. These assumptions generally ignore all wave properties of sound, choosing to model sound as independent rays, particles, or phonons. Geometric methods instead make some simplifying assumptions about the behaviour of sound, which result in faster but less accurate simulations. Wave-based methods aim to solve the wave equation numerically, simulating the actual behaviour of sound waves within an enclosed space. Room acoustics algorithms fall into two main categories: geometric, and wave-based.
