  • Publication number: 20210015443
    Abstract: There is provided a biological sound measuring device that, in a contact state of being in contact with a body surface of a living body, measures a biological sound of the living body, the biological sound measuring device including: a first sound measuring instrument that is configured to measure the biological sound; a second sound measuring instrument that is configured to measure an ambient sound of the biological sound measuring device; and a controller that determines measurement accuracy of the biological sound in the first sound measuring instrument based on a difference in intensity at a predetermined specified frequency between a first sound measured by the first sound measuring instrument and a second sound measured by the second sound measuring instrument, and that performs notification when the measurement accuracy is less than a predetermined value.

  • Publication number: 20210015444
    Abstract: There is provided a biological sound measuring device that has a member which defines a space to be sealed by a body surface of a living body in a state of being pressed against the body surface, and that measures a biological sound of the living body based on pressure fluctuation in the space. The device includes: a sound generator that generates a sound toward the body surface; a sound measurer that measures a reflected sound of the sound generated by the sound generator; and a controller that determines whether or not a contact state or a contact position of the member with respect to the body surface satisfies a condition necessary for measurement of the biological sound, based on the reflected sound measured by the sound measurer, and that performs notification when it is determined that the condition is not satisfied.

  • Patent number: 10893845
    Abstract: A wheezing detection apparatus includes a breathing sound detection unit that detects a breathing sound of a measurement subject and acquires a breathing sound signal in a time series expressing the breathing sound. The wheezing detection apparatus includes a determination processing unit that, in each pre-determined processing unit period, converts the breathing sound signal into a frequency space to acquire a frequency spectrum of the breathing sound, and based on a height and a width of a peak in the frequency spectrum, determines whether or not the peak indicates wheezing.
