In recent years research in the three‐dimensional sound generation field has been primarily focussed upon new applications of spatialized sound. In the computer graphics community the use of such techniques is most commonly found being applied to virtual, immersive environments. However, the field is more varied and diverse than this and other research tackles the problem in a more complete, and computationally expensive manner. Furthermore, the simulation of light and sound wave propagation is still unachievable at a physically accurate spatio‐temporal quality in real time. Although the Human Visual System (HVS) and the Human Auditory System (HAS) are exceptionally sophisticated, they also contain certain perceptional and attentional limitations. Researchers, in fields such as psychology, have been investigating these limitations for several years and have come up with findings which may be exploited in other fields. This paper provides a comprehensive overview of the major techniques for generating spatialized sound and, in addition, discusses perceptual and cross‐modal influences to consider. We also describe current limitations and provide an in‐depth look at the emerging topics in the field. 相似文献

在小尺度封闭空间内,声波低频成分的波长与空间尺寸相当,声音在传播过程中所发生的散射、衍射等波动现象不容忽视。目前以几何声学为理论基础的音质评价方法无法直接用于小尺度封闭空间中,需要发展以波动声学为理论基础的音质评价方法。以室内声场有源Helmholtz方程及其相应边界方程为基础,分别研究基于计算机辅助的全数字化小尺度封闭空间主观音质评价及客观音质评价方法。在这一部分,首先推导了求解小尺度封闭空间低频声传递函数的有限元模型;并进一步研究了在小尺度封闭空间内的双耳特性的处理方法;最后给出了小尺度封闭空间可听化的软件实现方法,并在一车体模型内实现了可听化。 相似文献
