Abstract

The invention relates to the field of visualization and automated analysis of the digitized cardiac auscultation (acoustic) signals. According to the invention, the method of cardio-acoustic signal analysis comprises the steps of: receiving a signal representative of heart sounds from an acoustic sensor; representing the received signal in a time-frequency-amplitude domain; where the method further comprises the step of applying a psycho-acoustic model to the received signal in the time-frequency-amplitude domain in order to generate a representation of the signal in a time - perceptual frequency - perceptual loudness domain. A device and a system are operative of performing the analysis of cardiac auscultation (acoustic) signals according to the method.
