Abstract
In this research, Otsu´s method methods is quoted and applied to de-noise heart sounds so that unwanted noises can be separated from a combined set of noises extracted through an electronic stethoscope. The noise was analyzed by applying a random but suitable threshold section method, the unwanted noise was reduced and the useful sound was reconstructed. The initial result shows that the method applied is effective and the reconstructed signal appears to be providing a better quality of heart sound.
