The actual sound environment system exhibits various types of linear and non-linear characteristics, and it often contains an unknown structure. Furthermore, the observations in the sound environment often contain fuzziness due to several causes. In this paper, static and dynamic signal processing methods for estimating and predicting the specific signal of sound environment systems with unknown structure and fuzzy observation are proposed by introducing a fuzzy probability theory. The effectiveness of the proposed theoretical methods is confirmed by applying them to the actual problem of psychological evaluation for the sound environment.
