Abstract
A wheezing detection apparatus includes a breathing sound detection unit that detects a breathing sound of a measurement subject and acquires a breathing sound signal in a time series expressing the breathing sound. The wheezing detection apparatus includes a determination processing unit that, in each pre-determined processing unit period, converts the breathing sound signal into a frequency space to acquire a frequency spectrum of the breathing sound, and based on a height and a width of a peak in the frequency spectrum, determines whether or not the peak indicates wheezing.
