Abstract:
PROBLEM TO BE SOLVED: To display, in acquiring sound information, performing frequency analysis, and determining a sound included in the information, while switching between analysis result screens on which the sound included in the information can be easily determined according to the type of the sound.SOLUTION: A frequency analysis part 32 performs time-frequency analysis of sound information acquired by a sound acquisition part 31 to create a frequency spectrum waveform (STFT analysis result), and performs frequency analysis again on a frequency component included in an area designated by a user in the frequency spectrum waveform to obtain an analysis result indicating information on the cycle and frequency of an abnormal noise (1D-FFT analysis result). A control part 33 displays, while switching between, an STFT analysis result screen and a 1D-FFT analysis result screen according to the user's operation.SELECTED DRAWING: Figure 3
