Monitor Your Baby’s Heart Beat at Home with a Fetal Doppler

Once you’ve achieved maternity, there are a range of interesting products that can help you make the most of your fertilized condition. One of our favorites is the BabyBeat, a doppler-type ultrasound device that lets you measure your baby’s heartbeat from as early on as ten weeks into your pregnancy.

You’ve probably heard of the “Doppler effect”, usually illustrated using a train whistle as an example. When a train is approaching, you hear the whistle, and as it comes closer, the tone of the whistle, becoming louder, also becomes significantly higher. As the train passes you, the sound seems to drop down and become lower again.

It isn’t that the train’s whistle actually varies in tone, though; the sound only seems higher as the train gets closer to you, and as it moves away, the tone sounds lower. The actual frequency of the tone is what you hear when the train is right next to you: the effect of speed and distance traveled changes your perception of the tone, which increases or decreases due to the direction in which it is traveling.

Doctors have used Doppler-based ultrasound for decades, not only for pregnant women but for medical and surgical applications. Ultrasound is based on the idea that you can locate things in space by sending out a frequency, which bounces off an object and returns to you at a measurably different frequency. By calculating the speed of sound in the first place and measuring the returning frequency, you can determine where things are inside the body. In the oceans, navy ships use a similar sound-based technology, called sonar, to locate underwater mountains and ridges as well as to track other ships. A ship sends out a tone, which bounces off other objects and returns as another frequency. This tone can be “read” by an expert sonar listener, or it can be fed into a computer and return as a readout. The ultrasound test performed by your OB-Gyn works in much the same way: the sound “bounces off” your baby, generating an image that’s displayed on a computer screen.

Find a Baby Doppler at a Discount When You Buy From Another Mom

Fetal dopplers can be quite an expense, especially when you condsider all the other baby items you will need to buy before you bring your newborn infant home. Why not save a little money on your baby doppler and buy it used on eBay. You will find many mom's selling thier used baby items they will no longer need - many in brand new condition. Find available used fetal dopplers.

If your pregnancy is at 20 weeks or more, you can start to hear you baby's heart beat with a baby heart rate monitor. Baby heart rate monitors are an inexpenive way you can hear your baby's heart beat at home. The beating heart sounds will not be as clear of a sound as the fetal doppler, but it will still be a great bonding opportunity for you and your baby. See several baby heart rate monitor styles.


Don’t confuse Baby Doppler products with an ordinary microphone! Microphones will magnify the sounds outside as well as inside your body, with resulting interference noises. They simply can’t be as effective as doppler-based systems. Doppler is an interactive technology, and more precise than any mic. Baby Doppler, or ultrasound, has until recently, only been available at scheduled appointments at your OB-Gyn’s office. Typically, every few months, the mom-to-be goes in for a checkup, and the baby’s image is projected on a screen, while the delighted parents listen to the baby’s heartbeat. Now, thanks to modern technology, you can listen to your baby’s heartbeat right at home, any time you like.

Extraneous sounds create a murky noise that interferes with your listening pleasure. Other baby doppler products record everything, including the sound of the probe moving across your skin. The BabyBeat’s unique audio processing function sifts out unwanted sounds, giving you a clear, easy-to-hear sound. Our specialized noise reduction system is very popular with parents-to-be who want to hear the baby, not static!

And what would our Noise Reduction system be without our specialized Home Theater system, featuring durable speakers and Superior Sound Quality! Our speakers are the best you will find in baby doppler products.

The BabyBeat have been designed to fit easily into your hand. Fingertip controls let you do whatever you need to without have to reach, twist or strain. Ideal for the pregnant woman who would rather not perform intricate yoga moves to listen to her baby!

The Velvet-Touch probe has a soft feel that is much more pleasant than the usual probe. (In fact, it probably shouldn’t even be called a “probe”. Let’s just call it the Velvet-Touch.)You won’t get chills or shivers when you use it.

All the BabyBeat Dopplers arrive at your door with 2 ounces of ultrasound gel, a reference guide and instruction manual, new batteries and a CD that teaches you which sounds you are hearing when you use your Baby Doppler.

Aside from being able to heart your child’s heart beating, the Advanced Technology Standard BabyBeat with Recorder also lets you record the sound. Unlike other baby doppler products, you don’t have to hook the BabyBeat up to a computer to record; simply press a button! You can save each BabyBeat session to play back at a later time. With CD recording capabilities on your home computer, you can transfer the recording to CD for a wonderful keepsake or gift for grandparents-to-be. (If you don’t have a CD burner, you can send the Recorder to us with your baby’s heartbeat on the last recording, and we’ll make the CD for you! The BabyBeat also contains the technology you need to send your baby’s heartbeat recording via email.

The Standard Babybeat Legacy Baby Doppler was our first baby doppler, and features an angled probe for maximum clarity of sound and Static Suppression Doppler to prevent unwanted noise. It uses one 9-volt battery, which is usually good for around 250 one-minute sessions. The Legacy is available for rent at only $24 a month. The Legacy is perfect if you don’t want to record, but only want to hear your baby’s heart. For only $30 a month, you can rent the Standard BabyBeat without the recorder (but you can get it with the recorder for only $2 more!. You may also wish to purchase your own for $499.

The BabyBeat is lightweight and easy to handle (a real boon when you can’t reach your shoes!) It runs off three long-lasting AAA batteries, and can usually provide 1200, one-minute sessions on one set of batteries. You can rent the BabyBeat with Recorder for $32 a month, or buy one for $499.
