Many sounds of life awaits your discovery

Traditional stethoscopes are used by medical doctors for auscultation - listening to the sounds of the body for medical diagnosis. The Stemoscope , on the other hand, can let us experience a lot more: we are surrounded by tons of internal rhythms coming from the human body, animals and plants, but seldomly notice them. Tune into these rhythms today with the Stemoscope and delight yourself with many surpirses.


Let’s listen to some sample sounds in the introduction video

Sounds of life have many bass (low pitch/frequency) components, and the typical smartphone speaker is not good at playing them. To ensure the best listening experience, we recommend you to use your EARPHONES  or HEADSET 🎧.

Stemoscope in Action - Video Review

"When you hear something cool and you want to record it you want to have another personal listen to it or if you're doing teaching with medical students how great would this be? Just put it there and everybody gets to listen as you record the sound."

Reviewed by Dr. Carlo Oller, a board certified emergency physician in US

"I wholeheartedly recommend it. I think it's a great product. For what is, I'm really impressed. It's rare that Kickstarter's kind of deliver on everything that they promise but credit to stemoscope. I think they've really followed through with this one."
