PROBLEM TO BE SOLVED: To provide a device that can reduce the capacity of an operation sound storage device.SOLUTION: The present invention is a device that processes an operation sound of a device 1000 to detect abnormality, and includes: operation sound acquisition timing determination means 735 for determining that a timing to acquire the operation sound is reached; operation sound acquisition means 731 for, when the operation sound acquisition timing determination means has determined that the timing to acquire the operation sound is reached, acquiring the operation sound of the device; an operation sound storage device 85 that stores operation sound data of the operation sound acquired by the operation sound acquisition means; and abnormality determination means 733 for comparing the operation sound data stored in the operation sound storage device with a known operation sound stored in advance in a known operation sound storage device to determine the presence or absence of abnormality. 【課題】動作音の記憶装置の容量を削減可能な装置を提供すること。【解決手段】本発明は、装置１０００の動作音を処理して異常を検知する装置であって、動作音の取得タイミングであると判断する動作音取得タイミング判断手段７３５と、動作音取得タイミング判断手段が動作音の取得タイミングであると判断した場合、装置の動作音を取得する動作音取得手段７３１と、前記動作音取得手段が取得した動作音の動作音データが記憶される動作音記憶装置８５と、前記動作音記憶装置に記憶された動作音データを、既知動作音記憶装置に予め記憶されている既知動作音と比較して、異常の有無を判定する異常判定手段７３３と、を有することを特徴とする。【選択図】図１
