How many decibels of noise has an effect on the fetus

In general, noise is extremely harmful to the fetus because high decibel noise can damage the hearing organs of the fetus.

A recent epidemiological study in Canada has also shown that fetuses that have been exposed to loud noises above 85 decibels (90 decibels for heavy truck stereos) have lost hearing acuity before birth.

When the fetus's hearing begins to develop, it is important to avoid a noisy environment, because if the environment is too noisy, it will have a great impact on the fetus's hearing. In addition, it can also greatly affect the growth and development of the fetus, so pregnant women must be very careful. So, how many decibels have an effect on the fetus?

From a physiological point of view, all sounds that interfere with people's rest, study and work, that is, unwanted sounds, are collectively referred to as noise. Noise pollution occurs when noise has an adverse impact on people and the surrounding environment. Long-term exposure of pregnant women to a noise environment of more than 50 decibels will cause endocrine gland dysfunction, and mental stress and endocrine system disorders will occur.

Exposure to strong noise can only cause harm to the health of pregnant women, and it will have many adverse effects on the fetus. Chinese scholars tested the children of female workers who were exposed to loud noise (above 95 decibels) during pregnancy, and compared the results with other children with similar conditions, and found that the former had a lower IQ level than the latter. This may be due to the fact that noise often causes uterine contractions, affecting the fetus's blood**, which in turn affects the development of the fetal nervous system.

In addition, pregnant women's exposure to loud noises (above 100 decibels) during pregnancy increases the likelihood of hearing loss in babies. This may be due to the direct inhibitory effect of noise on the developing auditory system of the fetus. Due to the many adverse effects of noise on the human body, China has formulated and published (noise hygiene standards for industrial enterprises) to make clear provisions on noise in production workshops or workplaces and other working places.

In order to protect the health of female workers and their children, women should avoid exposure to noise that exceeds the sanitary standard (85 90 dB) during pregnancy.

Influencing factors of hereditary diseases: Marriage between close relatives and hereditary diseases of either spouse will affect the normal development and development of fetal intelligence, and will bring irreparable harm to the family and society. Influencing factors of environmental pollution:

Including water pollution (heavy metal mercury, lead, etc.), air pollution (car exhaust, lack of oxygen, smoking, etc.), radiation pollution (X-ray, microwave, etc.), noise pollution, water iodine deficiency, etc., can lead to fetal intellectual development disorders. Factors influencing nutritional status: The establishment of brain development and function is closely related to nutrition.

In particular, insufficient or deficient supplementation of folic acid and protein directly affects the formation of brain cells. If a pregnant woman is malnourished in the first trimester, it will cause fetal brain cells and nervous system development disorders; Malnutrition in the third trimester of pregnancy will cause the number of fetal brain cells to increase insufficiently, and the cerebral cortical sulcus gyrus development will be impaired, thus affecting the intelligence of the fetus. Influencing factors of diseases and medications:

Viral infections and inappropriate medication during the first trimester of pregnancy can affect the development of fetal brain cells.

Sounds of more than 60 decibels will easily affect the development of the fetus, and pregnant women should usually use oranges to reduce noise exposure.

Decibel is a unit of measurement that measures the ratio of two quantities of the same unit, mainly used to measure the intensity of sound, and is often expressed in DB. "Fen" (deci-) refers to one part of ten talks, and the single digit is "bei" (bel), and generally only decibels are used.

Noise is a very annoying sound in our lives, sometimes some people will deliberately press the horn of the car, or those square dance aunts regardless of time, regardless of the place to make a loud noise to dance square dance, this behavior will attract many people to hate. We all know that if we exist in a noisy environment for a long time, it will cause great damage to our eardrums, which will affect our hearing, and will be directly deaf and unable to hear sound.

Noise will not only have a very big impact on us adults and children, even if it is a baby in the womb of a pregnant woman, if pregnant women often go to some KTV or bars in a similar environment, because it will be very noisy, then these noises will have a great impact on the fetus in the womb. Although there are some tissues in the mother's body that are in contact with it, as well as amniotic fluid, it will have a protective effect on the fetus, but this effect is very small, and it is a drop in the bucket.

If a pregnant woman stays in a noisy environment for a long time, these noises will cause damage to the fetus's auditory system, and if the noise intensity increases slowly, the damage to the fetus will also slowly increase. In the process of receiving, these noises can cause the fetus to be stunted when it is in the mother's womb, and at birth, the weight will be very low.

If the noise reaches more than 95 decibels, the long-term noise will cause the child's intelligence to be lower than that of other children after birth, which will affect the blood of the fetus**, and the continuous noise will interfere with the continuous contraction of the uterus, which is also harmful to the child's hearing system. <>

Therefore, in the case of pregnancy, try to avoid going to those noisy places, and do not often go to places where some aunts dance square dances. If you want to protect yourself and your children, don't think that this kind of thing doesn't matter, because in the end, it is the children who are hurt.

I think the impact of noise on the fetus is very large, although the fetus is still in the mother's womb, it is very sensitive to noise.

The impact is very great, if the fetus often listens to some noise, it will affect the growth of the fetus, and it will also affect the brain development of the fetus, and it will also reduce the immunity of the fetus, and it will also reduce the resistance of the fetus, and it will also cause some diseases in the fetus. So I think the impact on the fetus is very big.

Introduction: As a parent, you need to pay attention to the fact that to ensure the health of your children, you need to pay more attention to your diet in life. At the same time, it is necessary to eat a lot of rich nutrients, so that you can supplement the nutrients you need daily, which is also very beneficial to the child itself.

Then you can also listen to some prenatal education to ensure that the child can better face this new world when he is born, of course, like those noises will also have a lot of impact on the fetus, and you can understand the noise by consulting relevant information. It is very harmful to the hearing system, so pregnant women should avoid walking around in those noisy places. This will have an unnecessary impact on your children, and I hope to help you by consulting the relevant information here.

Health effects can have serious health effects on the health of pregnant women and can have adverse effects on the fetus. Studies have shown that if you make a strong noise during pregnancy, the intelligence level of the child after birth is lower than that of ordinary people. And the reason for this is most likely because of the continuous noise and then the poor contraction of the pregnant woman's uterus, which will cause the fetus's blood to not flow normally.

The effect on the fetus is mainly manifested in some hearing hazards, first of all, through the doctor's indication that the pregnant woman should need to refuse to accept noise during pregnancy. Hearing loss like those in babies can lead to a performance disaster due to the noise being developed in the fetus auditory system. And then there are some inhibitions, which are not good.

The hearing system caused a great deal of damage to his hearing system, and it led to a decline because he transmitted it through his mother's hearing system. If you want prenatal education, then you will choose some pure **, and turn the sound on to a very suitable situation. This ensures that you can relax your mood and is also very effective for the fetus.

The impact of noise on the fetus is indeed very large. It can also damage the baby's normal hearing, and it will also affect the fetus's mood stability. It will lead to a decrease in the immunity of the fetus, and it will also reduce the physical fitness of the fetus.

The impact of noise on the fetus is still very large, because too high a sound will affect the fetus's brain and ears, and his eardrum will be ruptured, affecting the nerves, which will delay intellectual development.

It is very loud, and when the noise is loud, the development of the fetus will be affected.
