Abstract

The disclosure generally relates to methods and systems for multi-frequency fusion for localization of impact induced soundwaves of a target industrial machine. Conventional wideband beamforming-based techniques accurately localize the impact hotspots, however with increased computational time while beamforming-based techniques reduce the computation time but worsens the localization accuracy. In the present disclosure, a composite acoustic map and a single-tone acoustic map of each of the one or more single frequencies obtained at each predefined frequency interval, are generated based on geometric parameters and a characteristic sound signal. Then, the one or more localization regions associated with each experimental trail that are common to the composite acoustic map and the single-tone acoustic map are determined. Lastly an optimal frequency range is determined using a localization loss function, a Kalman filtering technique, and a probability distribution function based on the localization regions, for localization of impact hotspots.
