Acoustic Emission (AE) is one of the nondestructive techniques, which experienced great progress during the last twenty years and still holding its significant position among other non-destructive evaluation (NDE) techniques. It is used mainly to localize crack in solid materials, especially in non-metalic ones, which are mechanically stressed. During the material deformation (when a crack is generated) the electric changes are appearing at the faces of the cracks. The electric dipole system then becomes a source of voltage induced on metal electrodes. The recorded electric signal consists of crack walls self vibration given by crack length due to an ultrasonic wave given by sample dimensions. This entry describes the usage of the acoustic and electromagnetic emitted signals from used piezo-ceramic sensors in order to localize the position of the crack in the granite sample. For computing position of crack were used algorithms developed in MATLAB v7.0 which processed AE and EME singal data file.
