Why the study?
Heart sounds and pulses are vibration signals in nature, prompting exploration into expanding mechanical vibration analysis technology into medical applications.
Vibration analysis technology using wavelet transform can be successfully applied to analyze physiological signals like heart sounds and pulses.
Exploratory vibration analysis of heart sounds warrants caution in practice; leaves open rigorous validation before clinical or research adoption.
In the field of engine maintenance and assurance, the technology of unit condition detection through vibration analysis is relatively mature. More and more patents and technical products have been released, proving the practical value of the technology in mechanical vibration from the application level. In medical science, signals such as heart sounds and pulses are also vibration signals in nature, in order to expand the application of the technology and explore the value of the technology in medical applications. In order to extend the application of the technology and to explore the value of the technology in medical applications, the wavelet analysis technology was used to program the Labview2022 software to implement the corresponding analysis program for the analysis of the collected physiological signals. Finally, the wavelet transform-based analysis of the physiological signals was successfully implemented. It is demonstrated that the design concept can be achieved by applying this technique, which makes it valuable in the field of physiological signal detection and analysis.
