Stemoscope - Listen to the Sound of Life
Stethoscope redefined. The Stemoscope lets you discover the sounds of life. You can record and share these sounds at ease and use them for STEM education, recreation and many other purposes.
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 surprises.

Truly wireless listening experience
Stemoscope transmits the sounds to the smartphone via Bluetooth. The phone processes and amplifies the sounds and sends them to Bluetooth earphones, Bluetooth hearing aids or wired earphones, in real time.
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 🎧.
Featured in media all over the world
The Stemoscope is sensitive enough to pick up more pronounced sounds fairly clearly – especially for educational purposes that do not require extensive distinguishing of more subtle heart sounds.

Stemoscope in Action - Video Review
The Stemoscope is fully complementary to a stethoscope. Iconic classic stethoscopes are still preferred the most by doctors to do diagnosis and treatment of the disease in their daily practice. On the contrary, the Stemoscope can be ideally used for non-diagnostic or non-treatment purposes, such as education, training and sharing of some interesting auscultatory sounds where applicable. Instead of replacing a classic stethoscope with a digital stethoscope, many doctors choose to get a stethoscope plus a Stemoscope.
