Electronic stethoscope prototype with adaptive noise cancellation

Abstract

Electronic stethoscope is developed to improve the limitations and add functions to a conventional stethoscope. In electronic stethoscope, sound is transformed into electrical signal which offers various benefits including signal quality improvement, signal record and signal transfer via wireless. Electronic stethoscope in the market is expensive. Therefore, this research aims to design and develop a low-cost electronic stethoscope prototype that can filter frequency, reduce external noise and make real-time digital signal processing.
