摘要 自 20 世纪 30 年代引入立体声以来，人类对逼真的听觉体验一直进行着孜孜不倦的追求。双耳音频处理
技术基于人耳听觉感知特性，利用计算机和数字信号处理等技术在听者双耳鼓膜处模拟出与真实场景相同的
声压，以期给人以 “身临其境” 的体验，一直是音频信号处理领域的重要研究内容，特别是近两年随着虚拟现实
等应用的蓬勃发展，得到更多关注。该文主要围绕双耳音频处理技术中所涉及的关键环节：双耳录音、双耳合
成、耳机重放、扬声器重放、头跟踪等领域，以及相关典型应用场景进行较为系统的介绍，最后给出总结与展望。

Abstract Since the introduction of stereophonic sound in 1930s, human beings have been pursuing more
authentic auditory experience. Binaural technology tries to simulate the same sound pressure at listener’s
eardrums as that in a real sound scene by using the signal processing techniques, which is expected to provide
listeners an immersed sense. It has been an important research topic in the field of audio signal processing,
especially with the rapid development of virtual reality in the last two years. This paper mainly focuses on
the key issues in binaural technology: binaural recording, binaural synthesis, headphone-based binaural audio
playback, loudspeaker-based binaural audio playback, head movement tracking and the associated typical
applications. Finally, the summary and prospect are outlined.
Key words 3D Audio, Binaural technology, Headphone playback, Loudspeaker playback
