Abstract: Stethoscope is one of the basic diagnostic tool used in the medical world. Traditional auscultation of heart, gastrointestinal and lungs sounds requires good listening skills and comes with experience. An attempt is made to modify the acoustic stethoscope in order to ensure efficient auscultation and diagnosis of a patient. The electronic stethoscope enables signal storage, processing, filtering and analysis of signals. It offers an advantage of amplification, noise reduction over the classical stethoscope. The BPM count predicts the abnormalities in the heart and can detect diseases. Through the GUI, a user can control different functionalities of the device. This paper aims to design and develop an electronic stethoscope with minimum complexity and lower cost.
