The use of a Fetal Doppler also can enhance the bonding experience, especially for the baby’s
father, as it allows him to be more aware of how his baby is developing.
How Fetal Dopplers Work
Fetal Doppler technology is based on the Doppleshift 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, expanded, or that the frequency would change. Doppler work on the principle of listening to reflections of small, high frequency sound waves (ultrasound). These ultrasound waves are generated by microscopic vibrations of piezoelectric crystals. When the waves are reflected from moving objects, such as a fetal 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.
Please always remember where domestic Fetal Doppler use is intended:
Fetal Doppler’s should not be used in any way for diagnostic or medical purposes by anyone other than a medical professional and should not be used as a substitute for regular prenatal care by a medical practitioner. Any concerns about your pregnancy should be addressed to your care provider.
