An information analyzing apparatus (100) of the present invention includes a waveform feature determining unit (30) and a sound-type determining unit (40). The waveform feature determining unit (30) applies waveform feature determination criteria used for classifying features of sound waveforms to a sound waveform included in body sound information collected by a stethoscope so as to specify a feature of the sound waveform. The sound-type determining unit (40) determines a sound type to which the body sound information belongs, on the basis of the feature of the sound waveform specified by the waveform feature determining unit (30). With this configuration, it is possible to analyze body sound information objectively and highly precisely and to present analysis results so that a user can efficiently utilize them.
