Research on Virtual Reality Sound Effects for High-Speed Train Simulation System

摘要

In this paper, virtual reality sound effects forhigh-speed train simulation system using wavelet denoisingalgorithm is studied. As one important part of the highspeed train operation system, virtual reality systemvisualizes most parameter in train operation process. Soundeffect system provides sound information to the wholesimulation system. It is greatly significance to the wholeeffect and reality of the simulation. Here we will introducehigh-speed train virtual reality sound analysis andacquisition method. Based on wavelet denoising algorithm,we analyze the filtering mechanism and realization of highspeedtrain virtual reality sound effect. Combining audiofiles and the type of virtual reality scene, we present a newvirtual reality sound model and realization mode; eventuallyoffer a new ideal and flexible solution to high-speed trainvirtual reality sound effect system.
