摘要
在飞行仿真应用中,为增强人在虚拟环境中的沉浸感,提供实时的声音环境是提高仿真可信度的重要手段。论述了飞行仿真中的声音渲染技术,系统分析了声音传播及人对声音感知的基本要素及声音渲染的数学模型,并对声音仿真中几个重要因素如方位、距离、多普勒效应等进行了讨论,最后提出一种比较适用于飞行仿真的声音生成及显示的方案。
The immersion of the participator or viewer in a flight simulator can be enhanced greatly if their auditory is stimulated. The issues of the sound rendering technology providing the real-time digital acoustic synthesis for reproduction via speaker are discussed. Based on the sound propagation and psychoacoustics, a mathematical model is made to explain the principle of three-dimensional sound synthesis, and several important factors in sound simulation such as Doppler effect and distance are discussed. Finally, the processes of sound materials copy-editing, hardware selecting and building of control software models are discussed.
