Let’s listen to some audio samples recorded with BabyStemo

The internal speaker of a smartphone is generally not good at playing such kind of sounds, so please wear your EARPHONES 🎧 and adjust the volume 🔊 to listen.

These sounds were recorded with "Turbo" on. The baby's heartbeats are more audible. It is recommended to use this mode when you look for the best location to listen to your baby's heartbeat.

Work differently from a Fetal Doppler

Different from Fetal Doppler, which emits ultrasounds to the baby's heart and synthesizes the heartbeat sounds based on Doppler effects, Stemoscope denoises and amplifies the weak sound signals from the baby's heart and make them audible.
