Design of an Automated Diagnosis System for Chest Sounds Analysis

In this paper the chest sounds were recorded using an electronic stethoscope exclusively designed. The aim of study is to investigate the separation of chest sound into lung and heart sounds. Since the lung and the heart are the vital organ of human, therefore the needs of immediate preventive and curative actions are primarily important. The sound separation was partially achieved using FASTICA. Further a system for automated diagnosis of heart sounds was developed using MATLAB.
