This paper describes a detection method of two types of separations for outward tile wall. One of the tile separations is an outer exfoliation separated the tile surface from mortar concrete, the other is an inner exfoliation deteriorated space between the substrate and mortar concrete. In order to research these separations, we focused attention on the wavelet analysis that enable to analyze the frequency element of a waveform on time phase continuously. An impulse sound by a small hammer was measured using a mockup wall that reproduced two types of separations, and then these sound data were inspected by wavelet analysis. As a result, the characteristics of two separations were semi-empirically recognized visualizing the wavelet plane and the quantitative parameters judged the two separations were obtained processing the wavelet data statistically.
