Acoustic event detection refers to the task of detecting each semantic segment in an audio stream and associating it with a classification label .Acoustic event detection is a fundamental technique for sound scene recognition and semantic understanding ,and it is very promising in many application fields ,such as the semantic understanding of the environmental sounds for a human‐like robot ,the con‐text aware of sounds in the travelling environment for an unmanned vehicle .In this paper ,the history of acoustic event detection is reviewed from the point of view of related fields and application requirements , meanwhile ,the typical works of acoustic event detection is introduced ,and the future research of acoustic event detection is analyzed .In the analysis of related fields ,we focus on the researches of speech recogni‐tion ,music processing based on computation ,and sound processing based on auditory .In the application requirements ,we introduce the works of context aware of sounds and multimedia information retrieval . Finally ,the state of the art in acoustic event detection is analyzed ,and its future research fields is predic‐ted .%声学事件检测是指对连续音频信号流中具有明确语义的片段进行检测与标定的过程。它是机器对环境声音场景进行识别和语义理解的重要基础，并将在未来类人机器人声音环境的语义理解、无人车行车周边环境的声音感知等方面发挥重要的作用。本文分别从与声学事件检测相关领域的发展历程以及应用需求出发，对声学事件检测的历史进行了回顾，介绍了典型的研究工作，并分析了未来的发展方向。在相关领域的分析中，重点介绍语音识别、基于计算的音乐处理及基于听觉特性的声音处理等方面的工作；在应用需求方面，介绍机器的环境声音感知与多媒体信息检索方面的工作；最后分析本领域的研究现状，并展望其未来的发展趋势。
