Although a significant amount of work has been carried out for visual perception in the context of unmanned aerial vehicles (UAVs), not so much has been done regarding auditory perception. The latter can complement the observation of the environment that surrounds a UAV by providing additional information that can be used to detect, classify, and localize audio sources of interest. Motivated by the usefulness of auditory perception for UAVs, we present a literature review that discusses the audio techniques and microphone configurations reported in the literature. A categorization of techniques is proposed based on the role a UAV plays in the auditory perception (is it the one being perceived or is it the perceiver?), as well as a set of objectives that are more popularly aimed to be accomplished in the current literature (detection, classification, and localization). This literature review aims to provide a concise landscape of the most relevant works on auditory perception in the context of UAVs to date and provides insights into future avenues of research as a guide to those who are beginning to work in this field.
尽管在无人机 (UAV) 环境中已经进行了大量的视觉感知工作，但在听觉感知方面却没有那么多工作。后者可以通过提供可用于检测、分类和定位感兴趣的音频源的附加信息来补充对无人机周围环境的观察。受听觉感知对无人机的有用性的启发，我们进行了文献综述，讨论了文献中报道的音频技术和麦克风配置。根据无人机在听觉感知中扮演的角色（它是被感知者还是感知者？），提出了一种技术分类方法，以及一套在当前文献中更常被目标化的目标（检测、分类和定位）。本文献综述旨在提供迄今为止有关无人机听觉感知的最相关工作的简明概述，并为那些刚开始在该领域工作的人提供未来研究方向的见解。
