论文摘要
作为一个关键的感官渠道，声音在改善虚拟环境的现实和沉浸式中起着至关重要的作用。声音可以提供重要的线索，例如声音方向性和空间尺寸。本文对虚拟现实，游戏，多媒体，计算机辅助设计中的声音仿真研究进行了广泛的概述。我们首先调查了各种声音合成方法，包括谐波合成，纹理合成，光谱分析和基于物理的合成。然后，我们总结了流行的声音传播技术，基于波浪的方法，基于几何的方法和混合方法。接下来，审查了声音渲染方法。我们进一步展示了最新的基于深度学习的声音模拟方法。最后，我们指出了该领域的一些未来方向。据我们所知，这是在计算机图形领域提供全面研究的首次尝试。
Sound, as a crucial sensory channel, plays a vital role in improving the reality and immersiveness of a virtual environment, following only vision in importance. Sound can provide important clues such as sound directionality and spatial size. This paper gives a broad overview of research works on sound simulation in virtual reality, games, multimedia, computer-aided design. We first survey various sound synthesis methods, including harmonic synthesis, texture synthesis, spectral analysis, and physics-based synthesis. Then, we summarize popular sound propagation techniques, namely wave-based methods, geometric-based methods, and hybrid methods. Next, the sound rendering methods are reviewed. We further demonstrate the latest deep learning based sound simulation approaches. Finally, we point to some future directions of this field. To the best of our knowledge, this is the first attempt to provide a comprehensive summary of sound research in the field of computer graphics.
