This project is the work of a large team, including Alex Pavlosky, Jennifer Glauche, Spencer Chambers, Mahmoud Al-Alawi, Kliment Yanev, Carrie Wakem, Shaker Shaheen, Mohammed Khdair, Mohammed Abu Matar and Tarek Loubani.
This project aims to create a research-validated stethoscope whose plans are
available freely and openly. The goal is for the bell to cost ~USD$1-2 to produce,
and the rest of the stethoscope to cost approximately the same. You can see the peer-reviewed publication relating to this stethoscope's validation here:

Currently, the stethoscope resulting from this project functions as well as the
market gold standard, the Littmann Cardiology III.
