Pregnant women are in a noisy environment for a long time

It is better for pregnant women to live in a relatively comfortable and quiet environment. Frequent noisy noises are not good for the mood of pregnant women, nor for the health of the baby. It is better to listen to beautiful music more carefully to improve the noise of the environment.

Harm to the fetus's English hearing

There used to be a misconception that the noise exposure of the fetus is transmitted through the mother's auditory system, so it seems that as long as the mother uses personal protective equipment such as earmuffs, it can also protect the fetus's auditory system.

But in fact, the noise received by the fetus is transmitted through the mother's abdominal cavity; when the pregnant woman's abdomen is exposed to strong noise, the fetus will also be exposed to strong noise.

Although various tissues in the pregnant mother's abdominal cavity, the uterus, amniotic fluid and other tissue structures can play a protective role in the fetus's hearing, the actual effect is very limited.

The fetus's inner ear and other structures are not perfect, and its hearing is very sensitive to the damage of system noise.

An Australian study shows that fetuses who have been exposed to strong noise exceeding 85 decibels have lost their auditory sensitivity before birth, and this effect will become more serious as the noise tolerance intensity increases.

Noise affects the growth and development of the fetus

Experts and scholars from all over the world have conducted many scientific studies on noise, which proves that strong noise can cause many adverse effects on pregnant women and fetuses.

When a pregnant woman's abdomen is exposed to strong noise, the fetus will also be exposed to strong noise, which will have many adverse effects on the baby's development. Doctors say: 85 decibels is the limit of the safety threshold.

Leading to delayed language development in the fetus

The ear canal of the fetus is stimulated by noise, which will damage part of the brain and seriously affect the growth and development of the brain, resulting in intellectual disabilities in babies or children after birth.

Some scientists have pointed out that the inner ear, which constitutes part of the fetal ear canal, begins to develop and grow from the 20th week of pregnancy, and its improvement process continues when the baby is about 30 days old.

Because the fetus's ear is in the process of development, it is very vulnerable to low-frequency noise. The low-frequency sound in the external environment can be transmitted to the uterus and affect the fetus. The fetus's ear canal is stimulated by noise, which can damage part of the brain and seriously affect the development of IQ.

Therefore, for the health of the baby, pregnant mothers must be careful not to be in noise for a long time. Some activities should be avoided if possible, such as KTV.
