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.
