摘要
虚拟听觉技术用于再现与真实声像一样的听觉效果,甚至可以优化听觉体验。它涉及心理声学、信号测量、计算仿真等方面,在虚拟现实、通信导航、助听设备和心理康复等领域具有重要应用,受到了科研工作者的广泛重视。该技术的一个重要应用是虚拟听觉空间的构建,其基础是个性化头相关传递函数的获取。近些年,出现了大量获取个性化头相关传递函数的方法。为便于各个方法的总结和分析,将这些方法分成声学测量、数值计算、基于人体特征的近似估计3类,对每类方法的研究进程和重要成果进行了概况总结。随后,从实际应用的角度论述了各种方法的优缺点,针对各类问题的研究方向提出了建议,对技术未来发展进行了展望。
Virtual hearing technology can reproduce the same hearing effect as real sound images,and may even optimize listening experiences.It involves psychoacoustics,signal measurement,computational simulation and other aspects.It has been widely applied in the fields of virtual reality,communication and navigation,hearing aids and psychological rehabilitation,and has attracted wide attention from researchers.An important application of this technology is the construction of a virtual auditory space,which requires the acquisition of personalized head-related transfer functions.Several methods for obtaining personalized head-related transfer functions have been proposed.To summarize and discuss these methods,we classify them into three categories:acoustic measurement,numerical calculation and approximate estimation based on human characteristics.Research progresses and important achievements within each category were then investigated.We analyzed advantages and disadvantages of various methods from the perspective of practical application,and then looked forward to new trends in technology development in the future.
