Abstract
In this paper, an electronic stethoscope for heart diseases based on micro-electro-mechanical-system microphone is developed. It consists of a stethoscope head, an electronic circuit, and an APP based on Android system. The circuit amplifies heart sounds picked up by the stethoscope head, and includes a band-pass filter to remove background noise. The supporting APP can record, replay, visualize, and upload the heart sounds. Experiment results show that the electronic stethoscope can collect high-quality heart sounds reliably.
