How many months does the baby start to have hearing?

The fetus generally begins to have hearing after 6 months, and generally after 26-28 weeks of pregnancy, the hearing will be fully mature, but it cannot be ignored until then. Hearing is formed gradually, nerve cells begin to develop within 12 weeks of pregnancy, and various types of cells related to hearing begin to develop gradually, and after 12 weeks, this framework is initially formed. After a long process of development and perfection, it will be fully mature after 26-28 weeks of pregnancy, so it is said that perinatal entry after 28 weeks becomes the third trimester.

Because after 28 weeks of pregnancy, most of the organs of the fetus are fully mature, of course, the lungs, gastrointestinal and other organs are still relatively weak.

When the fetus develops to a certain extent, the mother begins to give the fetus prenatal education, but when doing prenatal education, we must first understand when the fetus begins to have hearing, so how many months does the fetus begin to have hearing?

Many pregnant women will worry that when they are working or traveling, the noise from the outside world will affect the development of the fetus, and they are also worried that when they are in early education, the fetus will not develop hearing and can not get the desired results, and the fetus will begin to develop hearing at about 20 weeks, that is to say, the fetus will be able to vaguely hear the outside world at about five months.

In the first three months of pregnancy, the fetus is only a gestational sac, not fully developed, so it does not have complete hearing, until three months after the embryo is stable before it begins to really develop various organs, about five months of pregnancy The fetus can hear the sound, so at this time, the mother should pay attention not to appear in the occasion of too much noise when traveling, which is easy to affect the fetus.

If you want to have early education, you can also do it when you are pregnant.

Start at five or six months, if it is too early, it will not play a role, because the fetus before five months is not hearing, but it will make the fetus feel very restless and have the risk of miscarriage, so prenatal education should also be carried out at the right time, and the fetus should start when the fetus has hearing and is willing to accept it.

Normally, the fetus's hearing system begins to develop at four months, but at this time the fetus has not yet responded to external sounds, and after seven months, the fetus's hearing system has matured, and at this time, the fetus can respond to external sounds.

Initiatives are proposed. At the time of seven months of the fetus, the hearing system has been fully developed, and at this time, you can give the baby some comfortable and gentle ** to calm the fetus's mood.

Precautions. At the fourth month of pregnancy, the fetus's auditory organs begin to develop, and at this stage, the pregnant woman should not be in a noisy environment with constant noise.

Others begin to hear at a few months, and the fetus begins to hear sounds when the baby is 5 months old in the mother's womb.

The impact of external environmental factors on the fetus and pregnant woman during pregnancy cannot be ignored, especially the influence of noise. Normal people will feel uncomfortable in a high-decibel environment, resulting in adverse reactions such as tinnitus. Therefore, pregnant mothers should avoid places with high decibel noise to give their babies a good environment for development.

So, does a three-month fetus have hearing?

Fetal hearing is generally formed in the mother's body at 5-7 months, and can distinguish various sounds and respond accordingly in the mother's body. Studies have shown that the auditory system is the most developed of the several sensory organs in the fetus. In the fourth week after conception, the fetal auditory organs have begun to develop, but at this time, the development of the fetal auditory nerve center is not yet perfect, so it cannot hear the outside world.

By the 25th week of fetal development, the fetal sound transmission system has basically developed, and at 28 weeks, the fetus's sound transmission system has fully developed and can have auditory responses, at this time, the fetus has all the conditions to be able to hear sounds. During pregnancy, the fetus is surrounded by amniotic fluid in the womb and does not hear the outside world as much as we think. During this period, if you cooperate with prenatal education**, it will be helpful for the baby's growth and development.

At this time, ** prenatal education can be carried out. Prenatal education refers to the teaching of the fetus in the mother's body. This kind of prenatal education method has been used in many countries, such as the obstetrician in Canberra, Australia, who once asked 35 pregnant women to come to the hospital on time every day to admire**, and after the birth of the fetus, they are in good health.

One of the major effects of the expectant mother's regular karaoke is that it is likely to affect the fetus's hearing. Zhang Qing, deputy chief physician of the obstetrics department of the Second Affiliated Hospital of Zhengzhou University, said that the place where K sings is not affected by normal people, but pregnant women often go, and the content of carbon monoxide, carbon dioxide and nicotine in the air is very high, and the harm of pregnant women staying here is self-evident. At the same time, most of the song halls are equipped with high-power stereo amplification devices, and their sound decibels are very high.

If pregnant women are in such an environment for a long time, it will cause hearing loss, blood pressure increase, hormone secretion disorder, and directly affect the growth and development of the fetus. The baby's hearing is already formed in the mother's womb and is very fragile, so this environment can cause damage to the baby's inner ear, the development of hearing after birth, and even the brain cells. If you want the fetus to get the best prenatal education, you can do it at home or in a quiet, clean and elegant environment, or you can move gently with the first child, which can not only make the pregnant woman safe and entertaining, but also make the fetus get the best prenatal education.
