PROBLEM TO BE SOLVED: To provide a bioacoustic processing apparatus capable of suppressing the deterioration of accuracy in analyzing bioacoustic sound, which is caused by the state of attachment of a bioacoustic sensor, by urging a user to improve the state in response to noise types. SOLUTION: The bioacoustic processing apparatus 300, which processes acoustic signals from a bioacoustic sensor 200 attached to a body surface, includes: a noise-extracting unit 320 for extracting a noise component contained in an acoustic signal from the acoustic signal; a noise classification-determining unit 340 for classifying the extracted noise component into one of a plurality of noise types that correspond to different respective states of attachment of the bioacoustic sensor 200; and a noise countermeasure guide unit 350 for presenting to the user, information for urging the improvement of the states of attachment, that corresponds to the results of the classification.
