PROBLEM TO BE SOLVED: To provide a breath sound analysis apparatus capable of detecting a rale included in a breath sound, separately from the other sound types.SOLUTION: The breath sound analysis apparatus comprises: detection means for detecting information relating to the minimum value of the intensity of the spectrum of a breath sound and output means for separately outputting information on a normal breath sound and that relating to a rale included in a breath sound, on the basis of the information relating to the minimum value.SELECTED DRAWING: Figure 9COPYRIGHT: (C)2016,JPO&INPIT【課題】呼吸音に含まれる水泡音を他の音種と分離して検出可能な呼吸音解析装置を提供する。【解決手段】呼吸音解析装置は、呼吸音のスペクトルの強度の極小値に関する情報を検出する検出手段と、極小値に関する情報に基づいて、呼吸音に含まれる正常呼吸音と水泡音とに関する情報を別々に出力する出力手段とを備える。【選択図】図9
