沉浸式虚拟战场3 维音效仿真研究

为提高3维音效在虚拟战场仿真中的应用效果，增强系统的沉浸感和真实感，在对声音的静态、空间、同步和运动4种主要仿真属性进行分析的基础上，基于声音的虚拟重发技术，提出了虚拟战场3维音效仿真方案。仿真方案将战场声音划分为：方向性交互声音、碰撞性交互声音、近体声音、方向性背景声、无方向背景声5种类型，随后论述了声源素材采集方法和实现3维音效的技术手段，最后设计仿真实例进行分析验证。仿真结果表明：该方案实现的3维音效可有效提高虚拟战场的沉浸感和逼真度，减少大脑对视觉的依赖性，为此类虚拟现实系统的研发提供一定参考。

Research on Immersive Virtual Battlefield 3D Sound Effect Simulation

In order to improve the 3D sound effect in the application of virtual battlefield simulation, enhance the immersion and realistic of system. Through analyzing the 4 simulation attributes, such as statics, spatial, synchronize, and movement, based on sound virtual resend technology, put forward virtual battlefield 3D sound effect simulation scheme. The simulation scheme divides battlefield sound into direction interaction sound, collision interaction sound, approximate principle sound, direction background sound, non-direction background sound. Then discus sound resource material acquisition method and technology for 3D sound effect realization. At last design simulation example for analysis and verification. The simulation results show that the 3D sound effect of scheme can effectively improve immersion and realistic of virtual battlefield, reduce the reliance of brain on vision, and provide a reference for developing virtual reality training system.
