We propose a way of analysis of self similarity of a environmental sound wave for treating a state of environment of a sound quantitatively. That way divides a measurement wave in constant frame and expresses a state of environment of a sound by relationship of these similarity. This analysis requires the Hausdorff distance and searches a pair of frames that have minimum Hausdorff distance. And this analysis uses the frame that is transformed by reduction mapping that is defined in iterated function system. In this paper, we use the sound wave measured around Shibaura Institute of Technology (Tokyo, Japan). This analysis uses two kinds of data measured in the same point. One condition has mainly a traffic sound and another has a sound that mechanical sound of chain saw is added. In the result, this analysis has detected the different of the relationship of frame similarity in these two conditions. This paper explains the way of analysis and reports the results of analysis of two conditions. |
