| Outline of Final Research Achievements |
Monitoring technique is one of the key technologies which can identify various scenes of structures, whether conditions, disasters, and so on. In order to understand their situations, it is important that each property can be extracted from them. In this research, we proposed such monitoring techniques that sound environments can be grasped by estimating sound sources and can be expressed as a sound pattern. The usefulness of the proposed monitoring techniques was verified by some sound pattern identifications at a shopping mall. Moreover, in order to understand sound environments, we proposed a method of classifying sound sources. In the classification, the sound sources can be grouped such that each cluster is composed with as few outliers as possible. The effectiveness of the proposed classification was shown by being utilized in the proposed monitoring technique.
