- Abstract:
- Abstract: Heart sound signal analysis has broad application prospects because the heart sound from heartbeat and blood flow can reflect the health information of the heart. Herein, we introduced the mechanisms of heart sounds and units for heart sound acquisition. The signal processing and feature extraction methods (including short-time Fourier transform, wavelet transform, Wigner-Ville distribution, Hilbert-Huang transform, Choi-Williams distribution and artificial neural network) were also reviewed in order to provide desirable information for the clinical research of heart sound signal in future.
