Heart sound auscultation using a smartphone

Abstract

In this paper, we propose heart sound auscultation system using a smartphone. The top cause of death in the world is the heart diseases. These diseases can be treated in early daignosis, but it is hard to do that because the diseases are hard for patients to recognize. We will utilze smartphones, which recently get spot light in healthcare, for early diagnosis of heart diseases. It make auscultation easy for normal user, and it has enough computation power for classifying heart sounds. Although it has problems in that it utilize smartphone instead of medical stethoscope. We supplement these problems with our solution. Also we conducted co-experiment with SNUBH, and measured accuracy of our solution. It accomplished average 88% accuracy.
