An early indicator of the onset of material failure due to fatigue and/or stress is the appearance of microcracks. Generation of these cracks creates propagating acoustic signals in the material, termed Acoustic Emissions (AE's). This paper presents results from an ongoing investigation into the detection and characterization of microcracks using AE signals measured in the presence of strong correlated interference and white noise.
