ABSTRACT
ABSTRACT: This study attempts to develop diagnostic method that is capable of quantitative evaluation on detecting interfacial separation or defects inside the concrete. In this study, Wavelet Transform is applied to analyze sound signals from concrete structures. Discrete Wavelet Transform is applied to detect a possibility of existence of interfacial separations and also to measure the volumes from variations of Wavelet coefficients. Finally, the efficiency and applicability of proposed method is discussed through the several results of examinations.
