SPEAR: Phase-Aware Multi-Noise Removal for Supervised Fault-Event Detection and Localization in Simulated Factory Scenes

The proposed framework, SPEAR (Spatial Phase-aware Event Acoustic Ranging), attains an operating-range event-detection area-under-curve (AUC) of 0.981 against 0.932 for an unsupervised Mahalanobis reference over the same range; the main advantage is at −5 dB, where the spatial front-end raises the AUC from 0.945 agains...
