Abstract
A state evaluation system includes a sensor, a filter, a signal processor, and an evaluator. The sensor detects elastic waves which are generated from industrial equipment in operation. The filter can pass elastic waves having frequency characteristics based on abrasion which is generated in the industrial equipment. The signal processor extracts a plurality of feature values using the elastic waves passing through the filter. The evaluator evaluates an abnormality of the industrial equipment on the basis of a combination of the extracted plurality of feature values.
