Abstract:
(EN) A biological sound analysis device comprising: an acquisition means (100) that obtains first biological sound information indicating chronological changes in biological sound; a processing means (230) that generates second biological sound information by performing a first processing on the first biological sound information, said processing highlighting first noise information indicating noise included in the biological sound; a calculation means (240) that calculates correlation information (P(t)) indicating correlation during adjacent time periods in the second biological sound information; and an output means (250) that, on the basis of the correlation information, outputs second noise information indicating continuous noise included in the biological sound. As a result, continuous noise included in the obtained biological sound can be suitably analyzed.
(FR) La présente invention concerne un dispositif d’analyse de son biologique comprenant : un moyen d’acquisition (100) qui obtient des premières informations de son biologique indiquant des changements chronologiques de son biologique ; un moyen de traitement (230) qui génère des deuxièmes informations de son biologique en effectuant un premier traitement sur les premières informations de son biologique, ledit traitement accentuant des premières informations de bruit indiquant un bruit inclus dans le son biologique ; un moyen de calcul (240) qui calcule des informations de corrélation (P(t)) indiquant une corrélation pendant des périodes adjacentes dans les deuxièmes informations de son biologique ; et un moyen de sortie (250) qui, sur la base des informations de corrélation, délivre en sortie des deuxièmes informations de bruit indiquant un bruit continu inclus dans le son biologique. En conséquence, un bruit continu inclus dans le son biologique obtenu peut être analysé de manière appropriée.
(JA) 生体音解析装置は、生体音の経時的な変化を示す第1生体音情報を取得する取得手段(100)と、第1生体音情報に対して、生体音に含まれる雑音を示す第1雑音情報を強調させる第1の処理を行うことで、第2生体音情報を生成する処理手段(230)と、第2生体音情報の互いに隣接する期間における相関関係を示す相関情報(P(t))を算出する算出手段(240)と、相関情報に基づいて、生体音に含まれる連続的な雑音を示す第2雑音情報を出力する出力手段(250)とを備える。このようにすれば、取得した生体音に含まれる連続的な雑音を好適に解析することが可能である。
