Information processing method and information processing apparatus

Abstract

An information processing method includes acquiring, by an information processing apparatus, a time-series measurement signal of the acoustic emission of an object; calculating, by the information processing apparatus, energy of the acoustic emission of the object based on the measurement signal; extracting, by the information processing apparatus, either (i) a time-series signal of a first component obtained by removing a second component having periodicity from a time-series energy signal, or (ii) a time-series signal of the second component, as first extraction; and calculating, by the information processing apparatus, an index value relating to variation of the time-series signal of the first component or of the time-series signal of the second component.
