When the fetus is in the mother’s belly, is it “in the womb and cannot hear sounds outside the womb”? Of course not. Don't underestimate unborn babies, they are very capable. When can the fetus hear sounds?

Many expectant fathers and expectant mothers will pay more attention to the prenatal education of their children. Especially after the baby is 5 months old, they will carry out a series of music prenatal education or language prenatal education when they know that their hearing has developed.

However, it should be noted that prenatal education should be moderate, because during pregnancy, the fetus's main job is growth and development, and they spend more time resting. During pregnancy, you also need to pay attention to protecting the fetal auditory development.

The fetus lives deep in the "uterus" and cannot be seen or touched by mothers. It is born with a mysterious color, so mothers are very curious about the baby in their belly~

Nowadays, many pregnant mothers pay more attention to prenatal education and will listen to some music for their fetuses during pregnancy. At this time, mothers will definitely have a question, can the fetus in the belly hear sounds outside the womb? The fetus lives deep in the "uterus" and is not "blind to hearing things outside the womb"

The fetus has different characteristics at different stages of development. It will slowly develop from the initial cell mass, and then continue to complete. Become a real "baby" yourself.

The fetus’s ears also gradually develop during this process, so the fetus can hear sounds outside the womb in the belly.

The development of fetal "ears"

At 20 weeks of gestation, the fetus's hearing is still relatively weak. At 24 weeks of gestation, the fetal left and right cochleae The morphology of the fetus and the differentiation of the auditory nerve are basically completed, so the fetus can already hear sounds outside the womb at this stage. What sounds can the fetus hear in the mother's belly?

The fetus is not in a quiet place in the mother's belly. The environment, the "little home" of the fetus is very "lively".

The fetus can hear so many sounds in the mother’s belly. Mothers will definitely worry that these sounds will affect the fetus. In fact, the sounds that can be transmitted to the fetus’ ears are very weak.

Because sound signals have to pass through physical barriers such as the mother's body and amniotic fluid, in the fetus's small house filled with fluid, her eardrum and middle ear cannot work normally as they do in the air. The fetus' hearing conduction of sound waves is still mainly based on bone conduction, so the mother's very loud sounds are not obvious to the fetus.

To put it simply, the fetus in the mother’s belly can hear sounds outside the womb. At 20 weeks of pregnancy, the fetus’ hearing is still relatively weak. At 24 weeks of pregnancy, At this stage, the shape of the fetus's left and right cochlea and the differentiation of the auditory nerve are basically completed. At this stage, the fetus can already hear sounds outside the womb.

The fetus can hear sounds from the outside world, but it still depends on how many months the fetus is, because after the embryo develops to 15 weeks, we collectively call it a fetus. For fetuses before 15 weeks, basically For those without hearing, hearing should really begin around 15 and 20 weeks, but hearing is weak during this period, and external sounds need to reach a certain frequency before they can be heard! The development process of the fetal auditory system is mainly as follows:

Therefore, mothers who want prenatal education can choose to start around 5 months old, talk to their children more, listen to music, and read some picture books.

Fetuses will feel more comfortable with sounds between 500 and 1500hz. If they listen to more soft and gentle music, they will like it very much!

Pregnancy is an important period for the development of the child's auditory system, so mothers should also pay attention to some things during this period to prevent abnormal fetal auditory development! 1. Prevention of infectious diseases

The most feared thing during pregnancy is that mothers will get sick, especially infectious diseases. Especially in the first trimester, rubella virus, sporozoal virus, and cytomegalovirus may all cause damage to the fetal auditory system. Developmental abnormalities, so during pregnancy, you should try to avoid crowded places. 2. Pay attention to the safety of medication during pregnancy

During pregnancy, some people cannot avoid colds, fevers or other diseases. In serious cases, medication is needed. At this time, medication must be taken under the guidance of a doctor to avoid drug abuse affecting the fetus. Development of the auditory system. 3. Hereditary deafness disease

If someone in the family has hearing problems or has a genetic history, it is best to have a comprehensive examination before pregnancy, and then conduct genetic screening under the guidance of a doctor to reduce the probability of the child's inheritance. 4. Stay away from noisy environments

It can be seen from the development of the fetal auditory system that after the second trimester, the fetus begins to respond to external sounds. Long-term exposure to noisy environments can easily affect the development of the fetal auditory system, so during pregnancy You should avoid living in noisy environments and reduce going to excessively noisy places!

All in all, during pregnancy, you should try to avoid the environment, diet, and behaviors that are harmful to the fetal hearing to ensure the healthy development of the fetal auditory system. Pregnancy is no small matter. As expectant fathers and expectant mothers, you must pay more attention to ensure the health of your child. born.

Yes

Hello, I am happy to answer this answer for you. This is a question that makes all parents curious. Can the baby hear sounds outside the womb when it is in the mother's belly?

The answer is yes: the baby can hear the outside sounds, but not as soon as the mother is pregnant. It is only after the baby reaches a certain gestational age and the hearing system develops that the baby can hear the outside world. of sound. 1. Fetal auditory development

At 2 months: The auditory nerve is initially formed

At 6 months: The differentiation of the auditory nerve is completed

At 7-8 months: Ability to hear and respond to sounds.

Therefore, after 6 months, the baby will respond to external sounds, such as talking to the belly, and the baby will turn to the side with the sound. At this time, the mother can start prenatal education for the baby. 2. Famous fetal hearing experimental research 3. Fetus’ preference for sound

1. Fetuses like to listen to slow-paced light music and their mother’s voice.

Therefore, mothers can read some short stories or sing nursery rhymes to their babies at this stage.

2. Sounds that the fetus does not like to hear: noisy quarrels, excessive decibel noises, etc.

Therefore, after pregnancy, both parents should communicate more with the baby, and remember to use a gentle tone of voice, especially the father. Through communication, he can establish a close parent-child relationship with the baby early. 4. Factors affecting baby's hearing

1. Mothers should avoid using some drugs that damage hearing during early pregnancy.

2. Mothers should avoid exposure to harmful factors such as rays and radiation during pregnancy.

3. Mothers should not be exposed to noisy environments for a long time, as this is also very detrimental to the development of fetal hearing.

Regarding this question, can the fetus hear sounds outside the womb? This specifically depends on how many months old the fetus is. Generally speaking, a fetus around 5 months old can hear external sounds. Before 5 months, the fetus' hearing is basically developing and it cannot hear external sounds.

Therefore, if the pregnant mother performs prenatal education, it should be carried out after the fetus is 5 months old. At this time, the fetus can already hear the mother’s voice. You can listen to prenatal education music for the fetus. Expectant parents should also talk more with them. Fetal speech is beneficial to fetal brain development and auditory system.

Fetuses like to listen to soft and soothing music and do not like loud and high-decibel noises, so it is best for pregnant mothers not to go to noisy environments and places with loud noises.

You can hear some people saying that my belly is not soundproof haha.

In the first six months, my husband would move around when he snored. When I pushed my husband to stop snoring, he would become quiet. When I watch TV outside, the sound is loud and he moves around. When I turn the sound down, he becomes quieter.

Now in the third trimester of pregnancy, when I eat, he can hear the sound of chewing and food reaching the stomach, and he will move. When I stop, he becomes quieter.

The first time I did fetal heart rate monitoring, I had four pregnant mothers doing it together. The new pregnant mother needs to listen to the fetal heart rate first, and the machine will make a sound of fetal heartbeat. When this happens, Every sound made my baby's heartbeat soar. I felt like he was eavesdropping and curious, just like his father who loves to join in the fun.

I used a pressure cooker to make mung bean soup a few days ago. When the pressure was released, the pressure cooker made a little noise, and he moved around. Because I was standing, my stomach was sore for a while, and I couldn't help it. I could only go to the sofa and sit for a while. After sitting for a while, he became quiet.

Can the fetus hear sounds?

My answer is that it can be heard, because

Of course the fetus can hear sounds in the belly. The fetal auditory nerve begins to develop gradually from the 6th week of gestation to 24th week. The morphology of the left and right cochlea and the differentiation of the auditory nerve are basically completed. Hearing begins at 15 and 20 weeks. By the 25th week, it is almost equal to that of an adult. By the 28th week, it has sufficient ability to respond to sound stimulation.

When I was about 30 weeks pregnant, I went to sing with my friends. When I first entered the KTV, the baby kept moving in my belly, and the movement was very powerful. The baby stopped moving when I went out. He must have been telling me that it was too noisy there and that I couldn't sleep. It's amazing! So the baby can hear sounds while in the mother's belly. Mothers can talk to their babies more and listen to prenatal music. This way, the babies may be born with musical talent!

Yes

I remember when I was thirty-six weeks old, I went to see a movie. The sound in the movie theater was very loud, and he became very restless and kept moving. Even my stomach started to hurt. I picked up clothes later. I put on thick clothes to cover it and then gently told him that Mom was watching a movie and you had to be quiet for a while and went out immediately. Then he stopped moving and my stomach didn’t hurt anymore. Hahahaha. Then I finished watching the movie. Yes, he was still in my stomach. I fooled him when he was there

That’s fine.

Around 16 weeks of pregnancy, various structures in the fetus' ears are likely to have formed, and some babies can even begin to detect some sounds.

Some of the sounds your baby may hear initially include your pounding heart, your stomach growling, and the sound of air moving in and out of your lungs as you breathe. As hearing develops, the fetus will begin to hear more and more sounds outside the womb.

Research shows that around 24 or 25 weeks of pregnancy, many babies will turn their heads and respond to sounds. It’s amazing!

However, the sounds your fetus hears in the womb are different from the sounds you hear outside the womb. After all, they are surrounded by amniotic fluid at this time, and there are layers of your body tissues outside the amniotic membrane.

In addition, there is no air to help transmit sound, so even if the fetus' ears are fully developed, the sounds they hear in the womb are still relatively low.

Try covering your mouth while talking to the child’s father. It’s boring, right?

Although I can hear the intonation of the voice, I can’t understand the meaning - this is almost the sound that the baby hears in the womb.

But this also has the advantage that when there is a sudden loud noise around you, you don’t have to worry too much about scaring the baby in your belly.

Although the impact of long-term noise environment on hearing loss is not yet fully understood, if the noise is very loud, continues and occurs repeatedly, it will indeed cause certain effects on the growing fetus. some developmental damage.

For example, working in a noisy factory for 8 hours or more every day is enough to affect the hearing of the fetus.

Now that your baby can hear sounds outside, do you want to talk to your baby? But what the baby likes the most and hears the most is the mother’s voice.

The reason is very simple. All external sounds that the baby hears are first transmitted through the air and then through the uterus; but the mother’s voice reverberates directly through the body and bones in the body, and this process The sound will also be amplified.

In addition, some studies have shown that the fetus' heart rate will increase when it hears your voice. Yes, babies are more alert to their mother’s voice.

In fact, a study by PNAS (Proceedings of the National Academy of Sciences) found that babies can hear their mothers’ words and recognize these words after they are born; moreover, these “little smarts” can also Can recognize subtle changes in these utterances and process review information.
