IDMT-ISA-Electric-Engine Dataset

The IDMT-ISA-ELECTRIC-ENGINE dataset contains sound files of three similar units of an electrical engine (2ACT Motor Brushless DC 42BLF01, 4000 RPM, 24VDC), which simulate different acoustic conditions. The operational states “good”, “heavy load” and “broken” were provoked by a change of supply voltage and loading weight leading to a change of the operating sound. In March 2017 the IDMT_ISA_ELECTRIC_ENGINE dataset was recorded at Fraunhofer Institute for Digital Media Technology (IDMT). In each file, only one of the engines is active at the same time assuming an engine can only have one of the three operational states. The dataset consists of recordings of the electric engine plus the following background noise types: File duration: 42.32 minutes # Operational State “good”: 774 # Operational State “broken”: 789 # Operational State “heavyload”: 815 # Total WAV Files: 2378 Sampling rate: 44.1KHz Resolution: 32-bit Mono audioIDMT-ISA-ELECTRIC-ENGINE 数据集收录了三台同款2ACT型无刷直流42BLF01电机（转速4000转/分钟、额定电压24VDC）的音频文件，用于模拟不同声学工况。通过调整供电电压与负载重量，设置了“正常”“重载”“故障”三种运行状态，以此改变电机的运行声学特征。该数据集于2017年3月在弗劳恩霍夫数字媒体技术研究所（Fraunhofer Institute for Digital Media Technology，IDMT）完成录制。 每条音频文件仅包含单台运行的电机音频，且该电机仅处于上述三种运行状态之一。数据集包含电机运行音频与以下类型的背景噪声： 文件总时长：42.32分钟 - 正常状态样本量：774条 - 故障状态样本量：789条 - 重载状态样本量：815条 - 总WAV音频文件数：2378条 采样率：44.1kHz 采样精度：32位 音频声道：单声道
