摘　　要：空间声的目的是捡拾、传输和重放声场的空间信息,以产生期望的空间听觉事件和感知.空间声技术近年快速发展,是声学领域的前沿课题,并在众多科学研究、工程技术和文化领域有广泛的应用.声场的物理分析重构与空间听觉机理是空间声的两个重要基础,信号处理是实现空间声的技术手段.因而空间声的研究在声场、听觉、实际实现方面涉及声学(物理)、人类听觉感知、信号处理等跨学科的基础与技术问题.本文评述空间声的原理与发展,主要科学与技术问题、研究进展及代表性应用,并探讨了今后的技术和应用发展方向.Spatial sound aims to record, transmit, and reproduce the spatial information of the sound field and recreate the desired spatial auditory events or perceptions. It is a frontier field in acoustics and has undergone rapid advancement recently. It has also been widely used in scientific research, engineering technology, and cultural entertainment. The physical analysis of the sound field and the spatial auditory perception mechanism are two foundations of spatial sound. Signal processing is a technical approach for implementing spatial sound. Therefore, spatial sound handles fundamental and technical problems of sound field, hearing, and practical implementation in the crossfield of acoustics(physics), auditory perceptions, and signal processing. The principle, development, key scientific and technical problems, progress, and representative applications of spatial sound are reviewed in this article. Moreover, the technical and application prospects of spatial sound are addressed.
