This wheezing detection device is provided with a breathing sound detection unit that detects the breathing sounds of a subject and acquires a chronological breathing sound signal representing the breathing sounds. The wheezing detection device is also provided with a determination processing unit that, for each of preset processing unit periods, converts the breathing sound signal into a frequency space, acquires the frequency spectrum of the breathing sounds, and determines whether a peak (Pd) in the frequency spectrum indicates wheezing on the basis of the height (L) and the width (D) of the peak (Pd). |
