| Abstract(in English) | In the measurement and evaluation of actual random phenomena in a sound environment system, the observed data often contain the fuzziness due to the existence of confidence limitation in measuring instruments, permissible error in experimental data, and the variety of human response to phenomena, etc. In this study, by introducing probability measure of fuzzy events, a state estimation method based on the above fuzzy observations is theoretically proposed in a form appropriate for additive property of energy variable and the evaluation in decibel scale under the actual situation of existence of a background noise. The validity and effectiveness of the proposed method are experimentally confirmed by applying it to the actual fuzzy data observed in a sound environment. |
