This paper focuses on the observation of changes in acoustic emission and vibration signal to transverse crack on rotating shaft. The fundamental difference to other studies is the use of a microphone as acoustic emission sensor placed no direct contact with the part examined. The result of measurements of the acoustic emission signal compared with the vibration signal indicates that the acoustic emission signal apparently was seen and displays the number of maximum spectral peak fewer and amplitude values more consistent. Increasing the shaft speed and the depth of crack increases the magnitude of amplitude.
