Want to know how to listen to your baby’s heartbeat using your phone? In fact, AirPods can be used as a device for listening to fetal heartbeats when paired with an iPhone. You can hear the fetal heartbeat in a quiet environment. Some parents-to-be are curious about how many weeks into pregnancy you can hear the fetal heartbeat? Is this method really reliable? Mr. Crazy will share how to use iPhone and AirPods to listen to your baby’s heartbeat.
Why can AirPods be used as fetal heart sound? Decrypt the principle of instant listening on iPhone
In fact, the AirPods fetal heart sound function needs to be paired with the iPhone Live Listen function. The collected sounds can be instantly transmitted to AirPods, AirPods Pro or Beats headphones, so that conversations can be heard clearly in noisy environments.
As for the iPhone, it can also be used as a “fetal heart sound monitor”. The main method is to place the iPhone’s microphone close to the pregnant belly, amplify the sound in the abdomen, and play it through AirPods. In theory, the iPhone becomes a simple electronic stethoscope.
How to use iPhone with AirPods to listen to your baby’s heartbeat
Step 1: Add Hearing to iPhone Control Center
Swipe down on the upper right corner of the iPhone screen to bring up the Control Center, click the “+” in the upper left corner, and select “Add Control Item”.
Search for “Hearing” (the icon is an ear) on the control item gadget page, click on it and add it to the control center page.
Step 2: Put on AirPods headphones and set up
Put on your AirPods or AirPods Pro headphones directly and make sure they are connected to your iPhone. You can confirm from the control center whether the headphones appear, which means they are connected.
Next, press and hold the volume of AirPods to adjust it, and turn the sound directly to full. If you are using AirPods Pro headphones, it is recommended to turn on the noise reduction mode, so that you can listen to the heartbeat more clearly.
Step 3: Turn on instant listening mode
The recipient returns to the control center, long presses the “Listening” icon, and after entering, clicks the “Instant Listening” icon to open it.
Step 4: Use your iPhone against your belly to find the fetal heartbeat
Find an extremely quiet room to avoid interference from ambient noise, place the bottom microphone of your iPhone gently against your pregnant belly, and use AirPods to listen for sounds similar to a rapid heartbeat rhythm.
Finally, I will share the sound of Mr. Crazy’s baby’s fetal heartbeat. It is recommended to adjust the sound to the end, and you will hear a very fast heartbeat.
[Recommendation]Be sure to remove the protective case of the iPhone and let the microphone directly contact the skin. The sound collection effect will be better. Also, increase the volume of the iPhone appropriately. Pay attention while listening and do not keep shaking the phone or making any movements.
Did you hear that? How to differentiate between baby’s fetal heart sounds and noise
Even if you hear what sounds like a fetal heartbeat, many people will wonder if it is really the baby’s heartbeat? Here are a few benchmarks for identification:
- Sound frequency: The baby’s heartbeat is very fast, usually between 110 and 160 beats per minute. It sounds like a fast-moving train, and it is normal for the sound to be low.
- Mother’s heartbeat: relatively slow, about 60 to 100 beats per minute. If the rhythm you hear is synchronized with your own pulse, it is probably just the sound of the abdominal aorta, not the real fetal heartbeat.
- Gastrointestinal sounds: These are the most commonly misidentified sounds and sound like gurgling, watering, or irregular bubbling.
How many weeks does it take to listen to your baby’s heartbeat with AirPods?
Of course, some people will wonder how long it will take before they can hear the baby’s heartbeat. Normally, medical fetal heartbeat testing can be done after 6 weeks of pregnancy, when the heartbeat flicker can be seen through ultrasound equipment. Medical-grade fetal heartbeat meters sold on the market can only be audible after 10 to 12 weeks.
When can I hear my baby’s heartbeat with AirPods and iPhone? Although some people on the Internet claim that you can hear the baby’s heartbeat after 16 weeks, Mr. Crazy’s actual test suggests that you should wait until about 36 weeks before using an iPhone to listen to the baby’s heartbeat.
Of course, Apple’s official documents currently do not emphasize that AirPods can be used to detect fetal heart sounds, and no medical unit has listed this function as a detectable tool. It is impossible for AirPods to be used as a professional fetal heart sound monitor device. It only uses surface vibration to hear regular sounds, so whether it can be heard and where it can be heard still depends on the following conditions:
- Fetal weeks and position
- abdominal wall thickness
- Baby position (placenta previa is usually more difficult)
Why can’t I hear fetal heartbeats with AirPods? Do not use it as a fetal heart rate monitor
Using the instant listening function of the iPhone with AirPods to listen to the baby’s heartbeat can be regarded as using the latest technology to allow parents-to-be to hear the baby’s voice at home at any time. However, be careful not to rely too much on it, and don’t use the iPhone as an instrument to monitor fetal heartbeat. If you can’t hear it after trying for a long time, don’t panic. This is most likely due to insufficient weeks, the position of the fetus, or environmental noise. It does not mean that there is something wrong with the fetus.
If you want to hear the clearest and most reassuring sound of your baby’s heartbeat, it is recommended to have regular prenatal check-ups and submit the ultrasound and professional testing to an obstetrician and gynecologist.
Finally, I would like to remind you that although iPhones all comply with SAR value specifications, it is recommended not to hold the phone close to the belly of a pregnant woman for a long time. If possible, turning on airplane mode (only turning on Bluetooth to connect AirPods) can reduce unnecessary signal interference.
