Dad, I’ve finished reading the story. Oh, it’s your turn. Don’t pull down your homework, son!
During pregnancy, because I heard that all kinds of prenatal education are beneficial to the development of children, many expectant mothers will put forward the demand of [reading books and telling stories to the fetus] to the expectant father. Today, Clove Mother will come to analyze with you. Can the fetus hear the father’s voice? If you can’t even hear the voice, then all your efforts are nothing.
The 23-week-old baby has hearing.
Can the baby hear the sound in the uterus? This is a good question. Bao’s parents have experience. When swimming, they can hardly hear what’s voice when putting their heads under the water. The uterus where the baby is staying is full of amniotic fluid. Can the little fellow hear it?
In fact, in the 9th week of pregnancy, the baby grew earlobes. By the 10th week, the internal structure of the small ear will basically grow. You know, at this time, the little guy weighs less than 7g in total, which is only the size of a kumquat. However, it takes 23 weeks for the small ear to play its real function. Therefore, the baby is no stranger to this noisy world after birth. People have been listening to all directions for more than 4 months!
The voice the fetus hears is actually very awkward.
But does the sound sound like what in amniotic fluid? One father in Japan is very exploratory. This treasure father is Dr. Yamauchi Ichiro, honorary president of Japan’s National Okayama Hospital. He did an experiment with his own body.
Swallow the microphone ~
First fill the stomach with beer, then put the small microphone with cream and put it into the stomach. The cream dissolves in the stomach, becomes sticky beer, forms the same state as amniotic fluid, and then records. The results show that even in the stomach, music and TV sounds can be clearly recorded! However, this voice is not at all like his usual voice, which makes him feel very uncomfortable.
This is because when we speak, the sound will spread through two channels. One is to let others hear it through air transmission, which is called [air conduction]. This is the sound recorded by the tape recorder. One is the transmission through the speaker’s skull, which is called “bone conduction” and can only be heard by the speaker himself. We usually refer to [our own voice], which includes both air transmission and bone transmission, and when we hear the sound of a tape recorder that is only conducted through air, it certainly feels strange.
Baby’s ears prefer mother’s
What the baby hears is mainly the sound through [bone conduction]. Because the mother will accompany the vibration of the spine and diaphragm when talking, They are better able to deliver sounds to babies in amniotic fluid. Studies have found that only through air transmission, fathers’ voices penetrate the uterus by 35-40 decibels. You should know that the normal voice is 40-60 decibels, so babies with such a discount can hear not much.
So, if the fetus speaks, then he will definitely say:
Dad, your voice is so light and light (it is almost negligible)
Many irresponsible parenting websites say that fathers speak better to babies than mothers because their voices are lower and more easily heard by babies. After reading the above explanation, everyone can understand that this is bullshit.
Premature babies need their mothers’ voices more.
As we know, When the mother duck took the duckling for a walk, As long as the mother duck calls softly, The ducklings soon gathered. But scientists did a similar experiment with quails. Because the little quail also has similar conditioned reflex. The difference is that the little quail in the egg is not allowed to hear the mother’s cry in the late hatching period. The little guy hatched in this way can make the mother sad. No matter how the mother quail calls, they just won’t come.
Quail experiment has what relationship with us human beings? The proportion of premature babies in our country reaches 10%. Their organ function and adaptability are weak and they can only be separated from their mothers and admitted to the Neonatal Intensive Care Unit (NICU) for special care. Like those quails, they are less accompanied by their mothers’ voices in the last few weeks of development.
In general, such premature babies can also grow up healthily. Of course, there are also two related matters needing attention.
First, noise pollution must be reduced.
Without the isolation of the mother’s belly and uterus, Premature babies face much more noisy environment than babies of the same age who stay in their mothers’ wombs. For example, Premature babies can take their cries calmly, but other babies’ cries are annoying noises to little ones. Various noises will affect their normal work and rest and development, so special attention should be paid to reduce these noises as much as possible, such as talking, moving tools, opening and closing newborn incubators, etc.
Second, the mother’s voice should be increased.
Scientists found by recording the heartbeat of the fetus that the baby in the uterus can distinguish the voice of the mother from that of other women. When the mother starts to speak, the fetus’s heartbeat accelerates. While other aunts spoke, the fetus’s heartbeat did not change.
Using a similar method to do research, When the fetus hears the voice of the mother and father at the same time, Babies will have a preference for their mother’s voice. One possible explanation is that the father’s voice does not have [bone conduction], and most babies regard it as the external background noise. From this perspective, to cultivate feelings with the baby, it is precisely because they do not have too much strength during pregnancy that the father needs to work harder after the baby is born.
The father-to-be should continue to tell stories.
At present, there is no evidence that prenatal education can promote children’s development or make children smarter, but there are also data confirming that children who have undergone prenatal education do perform better. This is actually because prenatal education directly affects the spirit and emotion of pregnant women, thus indirectly affecting the brain development of the fetus. Therefore, the key lies with pregnant women themselves.
Therefore, in order to cultivate feelings with the baby early, expectant mothers can start trying to talk to the baby after 23 weeks. In addition, although the fetus is not sensitive to the voice of the father, it may be regarded as noise at all, but if the performance of the prospective father can win the happiness and satisfaction of the prospective mother, it is also indirectly promoting the development of the child, as long as it is well controlled not to be too loud and not too frequent.
