Abstract: The acoustic emission (AE) source wave analysis was carried out to examine the fracture process of concrete. The measurement method of frequency transfer function was proposed and the applicability of proposed method was investigated. These functions for specimen and transducer were obtained experimentally by the electronic pulse technique. When Eq. (4), in which the effects of characteristics of input and output wave were considered, was applied to calculate the frequency transfer function, the impulse wave was appropriate as input wave. The proposed method was available to the measurement of complex frequency transfer response. The source wave of AE was determined by using the detected wave and measured frequency transfer functions.
