For many years, been considered, fetuses are in the darkness of chaos, all day long in the sleeping state, knew nothing about fantastic panorama. If it really is like this?
No, many experiments and observation confirms this understanding is not correct, in fact, fetus also has some ability, auditory ability is one of: they can listen to the world in the dark. In the 13 weeks of pregnancy, if the mother rang the Bell near the abdomen will cause spastic fetal movement.
During pregnancy, a nickname from the parents to the fetus, and often calls for. After the birth of a child to hear him (her) when the nickname will suddenly stop milk, or quiet in crying, some even reveal the look seems to be happy. Often heard a few pieces of pregnant women during pregnancy, until the delivery. After the birth of a child, when you play the same music, most performance out of hand, foot and swing rhythms. When he was crying, and just heard listening to music in the mothers womb, will be stopped immediately, and show willing to listen to face action. Some pregnant women usually accomplishments, pregnancy often singing after birth the infant of the song has a good \"General\", heard his mother sing familiar songs, waving his hands, said he was happy, and left and right and stare, looking for sources.
Facts show that fetal dependence on the mother and the mother\'s voice with and sensitivity. If a man and a woman in the quiet voice at the same time on a newborn calls on both sides, this side of the neonatal turned to women in most of the time..
Scientists were also found, to pregnant women and the fetal play easily beautiful of light music, in b Super screen Shang see, each to once music stimulation, will caused fetal of movement, and respiratory rhythm and muscle tension different degree of change, also also in fetal heart monitoring instrument Xia do has also of experimental, dang instrument Shang display fetal of sleep wave type Shi, with respiratory device on with pregnant women abdominal calls several sound, fetal heart wave type will immediately recovery normal, description fetal can heard sound, and was \"wake\" has.
Pregnant women will remember the experience of carefully: outside has a sound all of a sudden, womb fetuses would be into a ball. Regular sessions of the noise and the sound of car horns in the streets caused frequent of fetal movement.
Scientific experiments and observations mentioned above is sufficient to show the fetus in the womb is not only in a State of sleep all day long, but hearing environment maintained close contact with the outside world, even acutely aware adults can\'t hear very low or very high frequency sound.
