The fetus is prone to hearing loss for a few months, will amniotic fluid protect the fetus s hearing

Around us, there must be a small number of deaf and mute, and these deaf and mute people in addition to congenital heredity, there are many factors that will cause the baby's hearing loss and even deafness, and there has always been a saying that ten deaf and nine dumb, many people are not born dumb, but because they can't hear the sound, the voice can not learn to speak, so to protect the baby's hearing, you need to pay attention from the pregnancy.

Generally, the hearing of the fetus begins to develop from 16 weeks of pregnancy, from this time, the baby can hear the mother's heartbeat and the sound of speaking, but these sounds because of the amniotic fluid and abdominal sound insulation, in most cases are about 30 decibels, can not affect the hearing of the fetus, and so on to 25 weeks of pregnancy, hearing can develop and mature, almost the same as adults, but it also needs to be 28 weeks when the baby will respond to the sound of the outside world.

Although the fetus has the sound insulation effect of the abdomen and amniotic fluid, so as to reduce the sound from the outside world by 20 decibels, if the expectant mother is in a noisy environment for a long time, then the protective power of the abdomen and amniotic fluid will be reduced, especially for those low-frequency sounds, which are not weakened, then the baby will be noisy.

Although babies like to hear the sound of others, they don't like noise, and long-term strong noise brings great harm to babies and expectant mothers. For example, expectant mothers may experience irritability, anxiety, hypoxia, uterine contractions, and even miscarriage and premature birth.

The direct damage to the baby is to affect its brain development, mental decline, hearing function and so on.

In fact, it is not only noise that will harm the fetal hearing, but also factors such as virus infection during pregnancy, improper medication, long-term nutritional deficiencies, and improper prenatal education methods will also affect the hearing of the fetus.

First of all, when you get married, you should do a marriage test, if both parties carry chromosomes with hereditary deafness, then it is recommended that for the sake of the next generation, it is recommended not to combine; Secondly, from the beginning of pregnancy, viral infections should be avoided, and any time you need to take medication, you must do it under the guidance of a doctor.

In addition, expectant mothers should supplement comprehensive and adequate nutrients for the normal development of the fetus; In addition, in the case of not knowing very well, avoid wrong prenatal education for the baby, and pay attention to avoiding places with high noise intensity in the environment where the expectant mother lives, such as KTV, on the street, etc. In fact, to protect the baby's hearing, it is necessary for parents-to-be to pay attention to protecting their hearing health, only if they are healthy, can they ensure the future of their children.

In fact, there is no need to worry about this, because the sound outside really has to reach the child's ears, in fact, his receptivity is very small. If the thickness of the stomach is combined with the thickness of the amniotic fluid, the child's hearing will not be damaged.

During the first trimester of pregnancy, or even throughout the second trimester, long-term exposure to noise can cause hearing damage.

Amniotic fluid can protect the fetus's hearing, because the presence of amniotic fluid can also reduce noise to a certain extent and protect the baby, so the baby is almost not disturbed by noise. In addition, the sound that the fetus can hear in the womb of the pregnant woman is relatively small, and because the fetus's own hearing development is not perfect, the sound that can be heard is very small, and the hearing is not sensitive enough, so the hearing of the fetus will not be damaged if it is occasionally exposed to noise. Of course, it is generally better to stay away from noise, after all, noise will affect the mood of pregnant women, and indirectly affect the fetus.

Definitely. Because amniotic fluid reduces the ingress of noise, it protects hearing to some extent.

1.Strengthen preconception testing.

Prevention of hereditary auritic chain deafness.

2.Prevention of infectious diseases in the first trimester of pregnancy.

Avoid damage to the auditory organs.

3.Safe medication during pregnancy.

Avoid drug-induced deafness.

4.Strengthen health management during pregnancy.

Guarantee physical and mental health.

5. Expectant mothers should supplement comprehensive and sufficient nutrients so that the fetus can develop its limbs normally.

6. Keep away from noise.

When the fetus's small ears are developed, if they are disturbed by external noise, it is easy to affect the normal development of the inner ear, resulting in hearing loss, so it is important to protect the fetal ears, so which ones will affect the fetus's hearing, I will introduce it to you below.

Step Method:

1 The first type is that if the pregnant mother is infected by the rubella virus, then the virus can be indirectly transmitted to the fetus through the placenta, when the rubella virus invades the cochlea, it will cause the baby to be congenitally deaf, so vaccination is the best measure to prevent rubella.

2 The second type is viral influenza, viral influenza will damage the human body to the vascular system and nervous system, pregnant mother's severe systemic toxicity can make the baby hypoxia and microcirculation disorders, thereby affecting the development of hearing, so it is best not to go to crowded places during the flu period, and it is best not to contact people with influenza.

3 The third category is ototoxic drugs, if the pregnant mother uses ototoxic drugs such as daqingmycin during pregnancy, if the dose is large and the time is long, it may also cause the baby's deafness, so you must not use the drug casually during pregnancy, or use it under the guidance of a doctor.

4 The last category is genetic factors, deafness is one of the most common genetic diseases, an average of 1 in 1000 newborns are born with deafness, so for mothers with a family history of genetic history, they should consult a doctor before pregnancy and then formulate a solution according to the actual situation.

Precautions. In addition to avoiding disease, radiation, ototoxic drugs, etc., it is necessary to avoid working in an environment where the noise intensity exceeds the national health standard.

High-frequency sounds can impair your baby's ability to hear English.

Medical clinical research has confirmed that prenatal education can increase the central neurons of the fetus, the dendrites are denser, the number of neurotransmitters is increased, and even the unrelated central neurons are connected to each other. Medical clinical studies have also shown that fetal babies are most suitable for listening to medium and low frequency tones in the womb, and men's speech and singing voices are dominated by medium and low frequency tones. Therefore, Dad is the best teacher in prenatal education.

What are the causes of hearing loss in fetuses?

**There are many ways to educate prenatally:

Song edification method and humming tandem resonance method. The song cultivation method refers to the soothing ** according to the broadcast, so that the daily life during pregnancy is filled with beautiful music, so that the pregnant woman's spirit is happy and the mood is happy; The humming tandem resonance method refers to the gentle tone of the pregnant woman humming the song lightly, and imagining the fetal baby listening, and then achieving the resonance point with the fetal baby's heart sound.

Fathers teach their children to "sing". The father is able to caress the mother's abdomen and gently "teach" some simple minor scales or nursery rhymes to the fetus in it.

Baby prenatal education device transmission sound method. From the 22nd week of pregnancy, under the specific guidance of the doctor, the appropriate baby prenatal education device and prenatal education songs are used to carry out the first prenatal education.

What are the causes of hearing loss in fetuses?

Minimize the noise of the tape or do not use microphones.

It is advisable to ask technical professionals to assist in the purchase of audio tapes. In order to ensure the quality of the audio tape.

It is not appropriate to listen to it for too long at a time.

**Prenatal education is mainly to carry out auditory training for the fetus. For example, when pregnant women are doing housework and tidying up the room, if they have time, they can hum some **, so that the fetus can continue to hear the charming singing of the mother in rhythm, and transmit the "love information content" of the human body, which is the most effective way to establish the basic communication between mother and daughter, and it is also very important to shape the fetus's sensibility. Pregnant women should listen to songs according to the rules of life, anytime and anywhere, but it is not suitable to wear headphones, and the sound should be controlled in the middle of 45 and 55 sound shells.

The time for the fetus to listen to the song is not too long, generally 5 10 minutes, and it is better to choose the time at 7 or 9 o'clock in the evening. All babies over 4 months old can listen to songs.

It is advisable to pay attention to three important points:

The first is the identification of infant hearing conditions. Although behavioral audiometry results are accurate, electrophysiological audiometry is only used in infants and young children under 6 months of age. Typically, we use methods such as click ABR, toneburst ABR, and multi-frequency steady-state evoked potential (ASSR).

Correct use of these methods can lead to more accurate hearing thresholds for infants and young children. When converting the electrophysiological response threshold to the hearing threshold, it is important to understand the application of the correction factor. The correction factor is the number of decibels that need to be subtracted from the ABR response threshold to the behavioral audiometry threshold.

In general, the electrophysiological response threshold ranges from 5 to 20 dB higher than the behavioral audiometry threshold. The low-frequency 500Hz needs to be subtracted by 20dB, while the high-frequency 4000Hz only needs to be subtracted by 5dB. For example, the threshold for obtaining ABR at 500Hz with a short pure tone is 60dBNHL, which translates to a behavioral hearing threshold of 40dBHL (60-20=40dB).

In this way, the hearing threshold of infants and young children can generally be obtained, which becomes the basis for hearing aid fitting.

Second, the unique acoustic characteristics of the infant ear canal must be fully considered. We know that the smaller the ear canal, the greater the resonance of the same sound intensity, that is, if we follow the 2cc index of hearing aids provided by the manufacturer, 90% of the time will lead to excessive amplification, making infants and young children uncomfortable, unwilling to wear hearing aids, and even affecting children's hearing. The best way to solve this problem is to test the true ear coupling cavity difference (RECD) in infants and young children.

Testing for RECD is very important and is one of the most important factors to ensure the success of hearing aid fitting.

After obtaining the recd values for infants and young children, the third factor is the evaluation of the effect of hearing aid fitting. In general, we can use a hearing aid analyzer to perform a real ear test using a probe microphone. The purpose of the assessment is to ensure that the indicators of infants and young children can be basically met after wearing hearing aids, such as gain, maximum output, etc.; Then see whether the hearing aid can effectively amplify the speech sound, the comfort of hearing aid does not mean that it can speak clearly, these need to be continuously evaluated and debugged, and finally, it is necessary to judge whether the function of the hearing aid is suitable for children's use, such as directional microphone, multi-memory hearing aid, wind noise reduction function, etc.

These features are not available to all infants and toddlers and are decided on a case-by-case basis.

In conclusion, a successful infant hearing aid fitting should meet at least the above three conditions. Of course, there are other factors to consider, such as inconsistent hearing loss in both ears of infants and young children, and the occurrence of rejuvenation. Therefore, infant hearing aid fitting is, in essence, a continuous, gradual and systematic process.

Hello! The cause of fetal hearing loss may be due to the mother's lack of caution during pregnancy. During pregnancy, expectant mothers should abstain from cigarettes, alcoholic beverages, and avoid noise (leaving the baby).

Even if you stay in your mother's womb, your baby's hearing is susceptible to noise. If the expectant mother is exposed to loud noise, the fetus in the womb is at risk of congenital noise-induced hearing loss. It is generally believed that the baby's hearing will be fully developed by 20 weeks and its ability to protect itself poorly.

Pregnancy expectancy in a noisy environment can also lead to preterm birth. According to a pediatric research report in the journal US, mothers who are exposed to 80db of noise for up to 8 hours increase the risk of preterm birth.

Effects of cigarettes, alcohol on the auditory organs:

According to a Swedish study, malnutrition and mycin from cigarettes and alcohol will reduce fetal cell formation, affecting the hearing organs for a lifetime. These babies may be born with fewer auditory cells than normal, increasing the risk of hearing loss similar to that caused by noise or aging.

Early studies have shown that cigarette and alcohol intake during pregnancy may lead to lower than normal hearing skills. The Swedish survey also showed that when the baby's hearing value is lower than the average hearing value, it may be due to poor conditions during pregnancy (cigarette intake, alcohol intake). I hope my answer is helpful to you.
