Database for the interpretation of phonocardiograms [PDF]
Journal of Physics: Conference Series, 2019 Abstract Using LabVIEW software, we built a set of images corresponding to cardiac sounds associated to diagnosed cardiac diseases. This constitutes an image database which facilitates phonocardiograms interpretation, also we made the correlation with diseases and the possible causes.

Segmentation of Phonocardiograms Signal [PDF]
International Journal of Engineering Research and Advanced Technology, 2018 Heart sound is a kind of bio-sound, mainly through the media pass sound signals. The measures of the heart sound signals involved in acoustics, fluid mechanics research. when added some noise for selecting pure PCG signal by using adaptive white Gaussian noise. Than denoise the PCG signal by using Discrete Wavelet transform and decomposes a signal into
