Deliverables/outcomes/results

Acoustic signal analysis has gained significant attention as a non-intrusive and effective method for fault detection in a variety of industrial applications [4,5]. Acoustic sensors (e.g., microphones) are quick and cheap to implement and do not require physical contact with the machine. In this context the fault detection is reduced to anomaly detection and there are several deep learning methods [2,3,5] that can be applied to classify normal and anomalous machine sounds. In all scenarios the main challenges are background noise and changes in machine operating conditions. In this project, the aim is to use deep learning based anomaly detection methods (e.g. “deep isolation forest”, “variational autoencoder” [7]) in combination with noise reduction techniques [3,6] to detect faults in industrial machines [1]. The benchmark dataset to this end is Malfunctioning Industrial Machine Investigation and Inspection (MIMII) [8].
