There is provided a vibration detecting apparatus including a biological vibration detecting unit that is capable of detecting a biological vibration, and a correction filter that corrects a frequency characteristic and a phase characteristic of a vibration signal obtained by the biological vibration detecting unit with at least an inverse characteristic of a characteristic of the biological vibration detecting unit.
Description
Technical field [0001] The present disclosure relates to a vibration detection device, a vibration detection method, a vibration detection system, and a program, and more specifically to a vibration detection device that detects biological vibrations including heart sounds and lung sounds. Background technique [0002] In order to improve the auscultation ability using a stethoscope, it is necessary to repeat the auscultation sound through medical examination and training. However, it is difficult to use stethoscopes other than familiar stethoscopes to diagnose patients because of differences in the acoustic characteristics of stethoscopes due to differences in performance and structural problems between products. [0003] Figure 53 A configuration example of an analog stethoscope 500 according to the related art is shown. The analog stethoscope 500 mainly includes a chest piece 501, a rubber tube 502, an ear tube 503, and an ear piece 504, and has degraded characteristics in each...
