Auscultation is a standard medical practice performed by clinicians when inspecting a patient during preliminary examinations. Auscultation is usually performed by using the stethoscope to listen to the body sounds. Wearable technology can automatize listening to body sounds and make the long-term monitoring possible. However, ambient noise can affect the performance of acoustic sensors.
The goal of this work is to develop an active noise-cancelling method to be embedded on a novel, 3D printed wearable stethoscope.


The project aims to design a novel, wearable stethoscope for long-term auscultation.
