Can be done. Therefore, the accuracy of analysis on the server 13 can be improved. As a result, the motivation of the user of the breath sound measuring device 1 to continuously perform the measurement can be further improved.
  • ⁇ Modification 1> For example, in the breathing sound information processing system 10 shown in FIG. 1, when the breathing sound measuring device 1 can communicate with the network 14 without going through the information terminal 12, the breathing sound measuring device 1 does not go through the information terminal 12. Measurement data may be transmitted to the server 13.
  • ⁇ Modification 2> The configuration of the measurement unit 3 shown in FIG. 4 is an example, and various modifications are possible. For example, when the above noise reduction is not performed, the sound measuring device M2 or the like may be omitted from the measuring unit 3.
  • the wireless communication unit 7 of the breathing sound measuring device 1 is a communication interface for short-range wireless communication
  • the wireless communication unit 7 may be a communication interface such as a wireless LAN.
  • the respiratory sound measuring device 1 may be provided with a communication interface capable of wired communication with the information terminal 12 instead of the wireless communication unit 7 or in addition to the wireless communication unit 7.
  • the communication interface capable of wired communication is, for example, a USB communication interface.
  • the wired communication interface 64 of the information terminal 12 shown in FIG. 6 also includes the USB communication interface, and the breathing sound measuring device 1 and the information terminal 12 are connected by a USB cable.
  • the breath sound measuring device 1 transmits measurement data and the like to the information terminal 12 by USB.
