I think, Freedomscope was the first to offer it - for doctors with hearing
Littmann Bluetooth Electronic Stetoscope with Ambient Noise Reduction is
more advanced and costs from about $350 to $800 and more. It allows to play
back sounds later and comes with heart & lung sound visualization software,
but the system letting others listen sounds in real time is sold
A study published this year by Dr. Lazzar's group from NY (
jason.lazzar at downstate.edu) concluded that electronic stethoscope holds
promise for HRV. They used lower-cost Thinklabs ds32a electronic
stethoscope, WinDaq and Kubios software along with their own custom
programs, so it was quite a project.
Disclaimer I, too, have no financial interest in these products and am
interested to know how reliable commercial software is, if anyone tried it
