  • Abstract
    The heart sound signals can be detected at all four cardio auscultation points using different microphones. This paper covers the detection of heart sound signals (S1 and S2) using the inexpensive MEMS microphone. It has the analysis of the heart sounds using Fast Fourier transform to detect the high intensity peaks of S1 and S2.
