Confused by the different types and models of dopplers?
If you have been looking at various websites and thinking of buying or renting a Doppler, you may well have become confused by the seemingly many different options available. However, in general there are two different types of real fetal dopplers. Those so-called 'pre-natal listeners' such as Bebe Sounds that simply amplify sounds within the abdomen are not dopplers. The two types are 'sound only' and 'digital' fetal dopplers. The sound only allows you to hear the baby's heartbeat. The digital fetal Doppler will also give you the sound but in addition it gives a digital display of the baby's heartbeats per minute.
How Fetal Dopplers Work
Fetal doppler technology is based on the Doppler shift principle. This theory was first discovered by Christian Doppler an Austrian physicist in 1842. Doppler discovered that sound waves from a moving source would be compressed or expanded, or that the frequency would change.
Dopplers work on the principle of listening to reflections of small, high frequency sound waves (ultrasound). These ultrasound waves are generated by microscopic vibrations of pizeoelectric crystals. When the waves are reflected from moving objects, such as a foetal heart the frequency changes slightly. It is this change that is analysed by the electronics of the doppler and converted into a sound that you can hear or a digital display of the heart rate.
