Claim:
1. A method for judging abnormality in a structure, comprising the steps of: detecting an abnormal sound, comprising the steps of: obtaining, by using the detected abnormal sound according to steps (a)-(w), a first geometric distance between an original standard pattern vector having a feature quantity of a normal standard sound as a component and an original input pattern vector having a feature quantity of an unknown input sound as a component and also obtaining a second geometric distance between an original standard pattern vector having a feature quantity of an abnormal standard sound as a component and the original input pattern vector; comparing the first geometric distance and the second geometric distance; and judging the input sound as normal when the first geometric distance is not more than the second geometric distance and judging the input sound as abnormal when the first geometric distance is greater than the second geometric distance.
