1. A biological sound measuring device, comprising:
a main body including:
a first sound measuring instrument that is configured to measure a biological sound,
a housing that accommodates the first sound measuring instrument therein, and that has an opening which is closed by a body surface of a living body in a state where the housing is pressed against the body surface,
a second sound measuring instrument that is provided outside the housing and that is configured to measure an ambient sound of the housing, and
a controller that causes a sound generator to generate a sound in a state where the opening in the housing is not closed, that determines whether or not a relationship between a measurement sensitivity of the first sound measuring instrument and a measurement sensitivity of the second sound measuring instrument satisfies a condition set in advance, based on an intensity of the sound measured by the first sound measuring instrument and an intensity of the sound measured by the second sound measuring instrument, and that when it is determined that the relationship does not satisfy the condition, notifies that it is unable to ensure measurement accuracy of biological sound or adjusts the measurement sensitivity of one or both of the first sound measuring instrument and the second sound measuring instrument.
