24.1.2 Virtual Reality What we now often refer to as virtual reality was first proposed in the 1960s [16,38,39]. In addition to the term ‘‘virtual reality,’’ many other terms such as ‘‘virtual environments,’’ ‘‘synthetic environments,’’ ‘‘virtual worlds,’’ and ‘‘artificial reality’’ have been used. Virtual reality has the capability of providing sensory information of sufficient fidelity that t...

In this paper, virtual reality sound effects for high-speed train simulation system using wavelet denoising algorithm is studied. As one important part of the high speed train operation system, virtual reality system visualizes most parameter in train operation process. Sound effect system provides sound information to the whole simulation system. It is greatly significance to the whole effect ...
