Summary: | To output information on a bubbling sound contained in a respiratory sound.SOLUTION: A respiratory sound analysis apparatus includes detection means (140) for detecting information on a minimum value of the strength of a respiratory sound spectrum, and output means (150 and 160) for outputting information on a normal respiratory sound and a bubbling sound contained in the respiratory sound separately on the basis of the information on the minimum value. The output means calculates an envelope curve of the minimum value from the information on a plurality of the minimum values, outputs information on the bubbling sound on the basis of a part corresponding to an area above the envelope curve, and outputs information on the normal respiratory sound on the basis of a part corresponding to an area below the envelope curve.SELECTED DRAWING: Figure 9
【課題】呼吸音に含まれる水泡音に関する情報を出力する。【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(140)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(150,160)とを備える。出力手段は、複数の前記極小値に関する情報から極小値の包絡線を算出して、包絡線の上側の領域に対応する部分に基づいて水泡音に関する情報を出力すると共に、包絡線の下側の領域に対応する部分に基づいて正常呼吸音に関する情報を出力する。【選択図】図9 |
