Some expectant mothers think that if you turn on your mobile phone or speaker and play prenatal music indoors, your baby can hear it. This is a very wrong approach.

The prenatal music played by mobile phones or speakers belongs to a single sound source with scattered directions. Music signals will be seriously attenuated and lost when passing through air, clothes, abdominal wall and amniotic fluid. At the same time, when the distance between the sound source (mobile phone or speaker) and the expectant mother changes, the volume of prenatal education music will also change. In other words, even if the fetus can hear prenatal education music, it may be big and small and intermittent. Even when the expectant mother is too far away from the sound source, the fetus can't hear the prenatal music clearly in some fetal positions. What about the effect?

How to avoid the above problems? The best way is to play prenatal music with multiple audio sources, such as the genius baby prenatal education instrument. The genius baby prenatal education instrument is equipped with four sound sources on its prenatal education belt, which forms a stereo sound effect and ensures that the fetus can receive even and stable prenatal education music signals in different fetal positions. In addition, in order to reduce the attenuation and distortion of prenatal education music in the process of air transmission, the research and development personnel of prenatal education instrument use three-dimensional abdominal wall coupling to transmit prenatal education music, just like the fetus wearing headphones with "high-definition stereo effect".

2. The effect of mother-child listening is good.

Listening to prenatal music every day by pregnant mothers belongs to the "indirect prenatal education" of music prenatal education, which can bring many benefits, such as:

Alleviate the bad feelings of expectant mothers such as thinking, irritability and pessimism caused by the surge of hormones, so that expectant mothers can adapt to prenatal education music more.

When expectant mothers hear pleasant prenatal music, the auditory nerve organs are stimulated, which causes the excitement of brain cells, changes the release of hypothalamic transmitters, and urges mothers to secrete some hormones beneficial to the health of mothers and fetuses, such as enzymes and acetylcholine, so that expectant mothers can maintain an excellent state. When the mother transmits these mysterious "happiness factors" to the fetus, it promotes the healthy growth of the fetus, thus achieving the effect of indirect prenatal education.

However, it can not be ignored that the fetus has developed to about 17 weeks of pregnancy and has already possessed the hearing ability. Fetuses can also listen to prenatal music, and the brain will respond to the music signals received. Different notes directly stimulate the activity of fetal brain cells through auditory nerves, producing more neurites and making the brain network more developed. This is the "direct effect" of music prenatal education.

Therefore, prenatal education should be that the fetus personally listens to the expectant mother at the same time, and the effect will be better.

It is safe to adjust the volume scientifically.

The volume control of prenatal music is very important! Research shows that when expectant mothers listen to loud music, the sound becomes "noise". The most direct impact is to interfere with the sleep of expectant mothers, affect the mood of pregnant women, and some will aggravate the pregnant reaction of expectant mothers, and the probability of suffering from pregnancy-induced hypertension will also increase. If pregnant women are affected by noise for a long time, it will cause dysfunction of endocrine glands in pregnant women, make the pituitary gland of pregnant women secrete too much oxytocin, cause strong contraction of uterus, and easily lead to miscarriage and premature delivery.

For the fetus, although the fetus already has hearing, it can personally receive the external prenatal education music signals. However, scientists have found that when the fetus is in a sound environment with excessive volume and high audio frequency, it will be restless and irregular, and even the fetus can be observed pouting and scratching its face. This shows that the fetus does not like these sound signals at this time.

Studies have shown that long-term exposure to noise during pregnancy will affect the healthy development of the fetus, damage hearing and intelligence, and even have a negative impact on personality development after birth.

After testing, it is confirmed that the volume suitable for the fetus during pregnancy is below 60 decibels and the audio frequency is within 2000 Hz. According to this, after years of research, the prenatal education instrument for gifted babies has increased the safe volume control function when playing prenatal education music to the fetus, ensuring that the volume and audio of music played to the fetus are always within the safe range.

4. Listen at the right time every day

From the above, we know that the fetus can receive sound signals outside the uterus at 17 weeks of pregnancy, which means that the best time to start music prenatal education is 17 weeks of pregnancy and the baby is born.

Do music prenatal education once every morning and evening 15-30 minutes each time. After fetal movement occurs in the second trimester, it is recommended to listen to the music prenatal education course of the excellent baby prenatal education instrument again during fetal movement.

Music prenatal education is a gradual process, and scientific and regular practice will have an effect on the fetus. Moreover, the fetus needs different music stimulation at each development stage, and it needs to be completed step by step in strict accordance with the music prenatal education settings in the excellent baby prenatal education instrument to ensure the final prenatal education effect. Expectant mothers can't fish for three days and dry the net for two days! The effect of music prenatal education is good, but the operation steps are crucial. I hope expectant mothers can master the correct methods and play healthy and scientific prenatal music for their babies!
