How quantitative measure of the heart sound can help us identify abnormal heart conditions?

This project focuses on analyzing the heart sound (auscultation) usually used by physicians to identify cases of abnormal heart condition.

The heart auscultation compared in this video focuses primarily on Patent ductus arteriosus (PDA) patients and compares them to a healthy person.
