Article Synopsis
- A new sound sensing system using stochastic resonance (4SR) was developed to generate an acoustic pulse wave (APW) by combining apex beat and heart sound, enabling real-time cardiac monitoring in healthy subjects.
- By analyzing APW and phonocardiogram signals, researchers identified boundary frequency (BF), which helps categorize cardiac apex beat (CAB) and cardiac acoustic sound (CAS) while correlating BF with heart rate using a quadratic function.
- The system demonstrated efficient cardiac movement during a heart rate of 70 to 80 beats per minute, allowing for detailed waveform classification and indicating potential for non-invasive, long-term biological pulse wave data collection and future AI applications.
