PROBLEM TO BE SOLVED: To provide a biological sound measuring apparatus, a biological sound measuring method and a biological sound measuring program capable of supporting accurate measurement of biological sound without enlarging the apparatus and increasing the production cost.SOLUTION: A biological sound measuring apparatus 1 for measuring biological sound of a living body with it coming into contact with a body surface S of the living body, includes: a first sound measuring instrument M1 disposed in a storage space SP1 tightly sealed by a body surface S in a contact state, for measuring the biological sound； a second sound measuring instrument M2 disposed outside the storage space SP1 for measuring peripheral sound of the biological sound measuring apparatus 1； and a control section 4 that determines measurement accuracy of the biological sound by the first sound measuring instrument M1 on the basis of a difference in intensity in a specific frequency between first sound measured by the first sound measuring instrument M1 and second sound measured by the second sound measuring instrument M2, and performs notification when the measurement accuracy is less than a prescribed value.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2020,JPO&INPIT【課題】装置の大型化と製造コストの増大を招くことなく、生体音の正確な測定を支援することのできる生体音測定装置、生体音測定方法、及び生体音測定プログラムを提供する。【解決手段】生体の体表面Ｓに接触した接触状態で生体の生体音を測定する生体音測定装置１は、この接触状態において体表面Ｓによって密閉される収容空間ＳＰ１に配置された、生体音を測定するための第一の音測定器Ｍ１と、収容空間ＳＰ１の外側に設けられた、生体音測定装置１の周囲の音を測定するための第二の音測定器Ｍ２と、第一の音測定器Ｍ１により測定された第一の音と、第二の音測定器Ｍ２により測定された第二の音の特定周波数における強度の差に基づいて、第一の音測定器Ｍ１による生体音の測定精度を判定し、この測定精度が所定値未満の場合に報知を行う制御部４と、を備える。【選択図】図５
