With the progress in modern knowledge and research, scientific studies have proven that certain types of sounds exposed to the fetus in the mother's womb play a big role in stimulating the development of the brain and intellect in a healthy and healthy way. However, we must be aware of the other side, as exposure to loud sounds or excessive noise can negatively affect the child's hearing and expose to many risks and complications, including the increased possibility of premature birth. Therefore, we will devote the next few lines of our article to aDalili Medical proof of the hadith about the effect of high-pitched sounds and harmful noises on the fetus during the period of its existence in the mother's womb in more detail.

When does the child start hearing sound?

Around the fifth month of pregnancy, your baby starts to hear the first sounds as a result of the maturation of his hearing organs. It is possible to hear loud sounds, such as heart beats and air movement in the lungs.

With the increase in the size of the fetus, the sounds become more clear. By week 25-26, the fetus will probably respond to sounds and noises. At this stage, you can hear the heartbeat in your abdomen whenever you are exposed to loud sounds.

Will your child be protected from the effects of harmful noise while in the womb?

The structure of the fetal auditory system is protected by abdominal muscles, placenta, and amniotic fluid. Therefore, the external sounds that the baby hears in the womb are the least powerful of the actual sounds.

However, it is not possible to determine how dangerous loud sounds are for your child, so it is recommended to be careful when listening to music and stay away from noisy places such as parties.

Moreover, loud noise can have a negative effect on the mother, as it increases the production of stress hormones, which increases the heart rate.

What are the types of sounds that pose a danger to the mother and the child?

Continuous exposure to loud noise can lead to hearing loss in fetuses. Therefore, to protect your child, it is best to observe the following points:

- Avoid going to shooting areas or shooting.

- I don't want to attend concerts. If you want to go, try not to sit in the front rows.

- Avoid working in places where the noise level exceeds 80 decibels.

- When listening to music, don't put the headphones on your stomach.

Who is the one who listens to the fetus in the womb?

The embryo's ear begins to form from the twenty-fourth week, and it forms the outer, inner, and middle ears. At this stage, the fetus begins to be affected by sounds, where these sounds are transmitted to the brain for treatment. The height of the fetus's response to sounds appears between the twenty-seventh and thirty-seventh week. We usually abbreviate intrauterine sounds due to the effect of the muscles of the throat and the walls of the uterus, which reduces the intensity of the sounds before they reach the fetus's ears. However, continuous exposure to loud sounds for eight hours a day, as is currently the case in some workplaces, especially if the sound exceeds 90 to 100 decibels, may lead to hearing loss or weakness in the fetus, in addition to increasing the chances of premature birth or delayed development. He has educational skills. Experiments on animals have shown changes in the structure of the nose of the fetus as a result of exposure to loud sounds. The researchers also point out that there is a relationship between these effects and the structure of the human nose, so it is preferable to avoid high-pitched concerts and exposure to strong sounds such as the sounds of airplane engines during pregnancy.

How much noise is safe for pregnant women and newborns?

Attention must be paid to exposure to high and frequent noise, such as those found in industrial workplaces, if it exceeds seven hours a day. The National Institute for Occupational Safety and Health recommends that pregnant women avoid exposure to normal noise that exceeds 115 decibels, such as the sound of a saw. In addition, short and frequent exposure to loud sounds up to 150 decibels or more, such as the sound of an airplane engine, can lead to similar problems for fetuses or newborn babies.

**How ​​does Al-Awsat al-Aaliya affect the jinn?**

1. **Excitement of the child** Exposure to loud sounds can cause the excitement of the fetus. When you listen to loud music, you may notice that your baby moves more cheerfully in your stomach, or that the movements become more intense.

2. **Effect on the hearing of the Eljinin** Humans can tolerate sounds up to about 80 decibels, and if they are regularly exposed to levels higher than that, their hearing may be endangered. In concerts, the sound of the instruments reaches a volume of more than 80 decibels, which can negatively affect your child's hearing.

3. **The cause of birth defects** Pregnant women who are constantly exposed to noise face an increased risk of premature birth, low birth weight, and their children are more prone to hearing problems at birth.Moreover, a study in the United States about the effect of noise on fetuses showed that the average height of deformed children increased from 0.8% to 1.2%. This is attributed to the fact that loud noise causes high blood pressure in pregnant women, which negatively affects the health of the fetus.

4. **The effect of stress on the newborn** Repeated exposure to loud noise leads to an increase in the levels of cortisol and corticotropin in the fetus. The higher these hormones are, the more likely the child will be stressed after birth. However, there are currently no studies proving that high noise has a negative effect on the fetus.

5. Changes in the structure of the nose of the fetus** High-pitched noise leads to changes in the structure of the nose of the fetus. Despite the lack of human studies, it is recommended to avoid exposure to loud noises during pregnancy.

6. Increased risk of premature birth** There are several factors that lead to the birth of premature babies, including exposure to noise. According to studies, pregnant women who are regularly exposed to loud noise can reduce the duration of pregnancy from 40 weeks to 37 weeks.

He is listening to Eljinin Is the music quiet or not?

Pregnant women listen to loud music, which may affect the development of the fetus, which makes you wonder if you should allow your baby to listen to music. Researchers agree that listening to music can be beneficial for both the mother and the baby, provided that the sound level is low or within the permissible limits. Quiet music can have a positive effect on both the mother and the fetus. When listening to music, you relax and reduce stress levels, which positively affects the development of the fetus in the womb. Don't try to listen to the music, just because others say that it is beneficial for the fetus. Instead, listen to your favorite music, this will help to relax the cells of the nose and increase the release of endorphins in the blood, which promotes the development of nerve cells in the fetus. Moreover, you should avoid music with strong or constantly changing rhythms, as these types of music may not be beneficial for your child. Currently, scientists are still conducting studies to determine the effect of noise on the jinn.

Tips to protect the mother and my fetus from noise?

1- It is preferable to avoid loud sounds as much as possible, especially for ladies who work in noisy environments. It is recommended to use earplugs to reduce the negative effects on the nerves of the mother, which may affect the development of the fetus.

2- The sound level in the workplace should not exceed 85 decibels, which is the level that allows talking to the last person without the need to turn up the sound. If the sound is louder than that, it may be difficult for me to communicate.

3- When the fetus reaches the 20th week, the auditory system will be developed enough to be able to hear the noise. In the twenty-fourth week, the fetus begins to respond to sounds. Therefore, it is important to avoid high sounds during this period.

4- It is necessary to avoid the presence of sources of loud sound near the womb of the pregnant mother, as the sound reaches the fetus in a greater way, in addition to the fact that the vibrations caused by the sound may have a negative effect on the fetus.

5- If the nature of a pregnant woman requires being in a noisy environment, it is preferable to stay away from sources of noise as much as possible.

- If the working environment suffers from high levels of noise, it is recommended to contact the supervisor to review the noise levels. If it exceeds 115 decibels, it is preferable to avoid exposure to noise during pregnancy. It may be difficult to stay away from noise in the workplace, so it is recommended to check with the employer about the possibility of moving to a quieter job during pregnancy.

- In addition to high continuous noise, you must avoid sudden sounds or pulsating noises.

- Increased sounds for your baby when your stomach is close to me. Therefore, it is better not to rely on anything that puts a body in direct contact with noise sources. Also, you should avoid relying on sources of vibration.

- The low-frequency sounds reach the fetus easily, as they travel through the mother's body and affect the fetus.

- Use earplugs to protect your hearing if you are exposed to loud noises. Although protecting your hearing can prevent the impact of loud noise on your unborn child, excessive exposure to noise can lead to stress, which causes physical changes that affect the fetus.
