How does the Doppler work ?
The Doppler listens to the reflections of small, high frequency sound waves that are reflected from within the womb. These sound waves are picked up by the probe and amplified through the hand held speaker so that you can hear them clearly. There are a variety of sounds that can be heard, including the fetal heartbeat, each of which is distinctive and so are easily identified. You can hear kicks and hiccups when your baby grows larger.
