In this paper, we propose a method to classify new and used bills using acoustic data of a banking machine. The proposed method employs an acoustic energy pattern as the time-series data of acoustic energy of the banking machine. By using the energy patterns, we have obtained better classification performance than that of the conventional method using spectral patterns of the acoustic data of the banking machine.
