地面移动机器人小尺寸麦克风阵列自噪声数据集

地面移动机器人在运行过程中会产生某些机械噪声。通过搭载拾音设备，可以对这些机械噪声进行录制。本数据集为通过搭载4个8元线性麦克风阵列对地面移动机器人的机械噪声进行录制的音频数据。录制的音频文件中不可避免的还包含实验环境的背景噪声数据。数据集共包含一次实验的数据。由于我们同时通过4个8元线性麦克风阵列进行录制，每个8元线性麦克风阵列对应1个音频文件，因此共有4个音频文件。所有4个音频文件的时长均为7分40秒。数据集用于地面场景下基于听觉信息的人员搜救。

Ground mobile robots generate mechanical noises during operation. These operational mechanical noises can be recorded using integrated sound pickup equipment. This dataset consists of audio data of the mechanical noises from ground mobile robots, recorded via 4 sets of 8-element linear microphone arrays. The recorded audio files inevitably contain background noise from the experimental environment. The dataset only includes data from a single experiment. As simultaneous recording was conducted using the 4 sets of 8-element linear microphone arrays, each array corresponds to one audio file, resulting in a total of 4 audio files. The duration of all 4 audio files is 7 minutes and 40 seconds. This dataset is intended for auditory information-based personnel rescue in ground scenarios.
