In order to investigate a method for efficiently monitoring multiple machines in a building with an acoustic sensor, an experiment was performed to acquire acoustic data of three rotating machines running simultaneously in a state in which all three machines are normal or one of three is abnormal, with two microphones placed at different positions. The abnormality can be detected from the acoustic signal level, and it can also be specified that the bearing abnormality has occurred by frequency analysis. A m...
