摘要

PROBLEM TO BE SOLVED: To provide a respiratory sound analyzer capable of accurately analyzing a respiratory sound to precisely detect intermittent rhonchus or continuous rhonchus even if the respiratory sound is recorded in an environment affected by noise or the like.SOLUTION: In a respiratory sound analyzer, a filter processing unit 120 extracts a signal with only a predetermined frequency bandwidth as a signal to be analyzed from a respiratory sound signal. A peak extract unit 130 preliminarily extracts possible peaks of intermittent rhonchus or continuous rhonchus based on characteristics of the intermittent rhonchus or continuous rhonchus. An erroneous detection correcting unit 140 corrects the peaks extracted by the peak extract unit 130 based on the characteristics of intermittent rhonchus or continuous rhonchus.
