| 摘 要： | 声音环境是整个虚拟环境的重要组成部分，真实感声音的生成是虚拟环境仿真中的关键技术之一。利用听觉通道可以加强用户视觉通道的感知，听觉感知的效果直接影响着虚拟环境的逼真度和沉浸感。文中对空间听觉感知模型进行了探讨，提出了听觉感知的生理认知模型和心理认知模型；论述了真实感声音生成的数学模型，给出了Wondows环境下生成真实感声音的多种方案。

| Abstract: | Sound environment is the important component of the whole virtual environment. The creation of realistic sound is one of the key technoques in virtual environment simulation. Users can enhance their perception of vision channel by using aural channel. Both fidelity and immersion of virtual environment can be affected by the effect of aural perception. This paper discusses spatial aural perception model, and two models of aural perception are introduced, such as physiology cognitive model and psychology cognitive model. Based on the discussion of mathematics model created by realistic sound, this paper shows several methods to build realistic sound under Windows environment. |
