摘要
可听化和可视化是构建虚拟视听环境的两个重要方面。本文结合几何声学原理、计算机技术和信号处理理论,研制了一种三维空间视听一体化仿真系统CAVS。文中给出了这一系统的主要算法和系统的设计方法。从程序运行情况和虚拟结果来看:该系统既具有良好的可视化功能,又能产生准确度较好的虚拟声学效果。
Both auralization and visualization are very important for building up a virtual sound environment. In this paper, we integrate the basic principle of geometrical acoustics, the computer technique and the theory of signal processing to design a combined auralization and visualization system (CAVS). We describe in detail the main algorithm and the realization of the system. The execution of the application and the modeling result show preliminarily that our program not only has the function of visualization, but also can produce credible virtual sounds.
