1. A method for cardio-acoustic signal analysis, comprising:
- receiving, via a signal receiver, a signal representative of heart sounds;
transforming, via a processing unit, the received signal to represent a time, perceptual-frequency, amplitude domain;
applying, via the processing unit, a human auditory system modeling algorithm to the time, perceptual frequency, amplitude domain representation to generate a time, perceptual-frequency, perceptual-loudness domain representation; and
displaying, via a visualization unit, the received signal in the time, perceptual-frequency, perceptual-loudness domain representation.

Abstract
A method for cardio-acoustic signal analysis includes receiving a signal representative of heart sounds and displaying the signal in a time-perceptual frequency-perceptual loudness domain representation. The received signal is transformed to represent a time-perceptual frequency-amplitude domain. The method further includes applying a human auditory modeling algorithm to the time-perceptual frequency-amplitude domain representation to generate the time-perceptual frequency-perceptual loudness domain representation.
