There is provided a vibration detection device, a vibration detection method, and a vibration detection system, the vibration detection device including: a biological vibration detection unit capable of detecting biological vibrations; Correcting the frequency characteristic and phase characteristic of the vibration signal obtained by the biological vibration detection unit, wherein the correction filter is a multi-stage filter, and the multi-stage filter includes a predetermined number of static filters with fixed filter characteristics and a predetermined number A dynamic filter with variable filter characteristics.
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 particularly, to a vibration detection device that detects biological vibrations including heart sounds and lung sounds. Background technique [0002] In order to improve auscultation ability using a stethoscope, it is necessary to repeatedly listen to auscultation sounds through medical examinations and training. However, because of differences in acoustic characteristics of stethoscopes due to performance differences between products and structural problems, it is difficult to diagnose patients using stethoscopes other than familiar stethoscopes. [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 a degraded characteris...
