Mother \"not\" scolded hurts the fetus

Fetal heard what feeling, it is with great interest. Outside voices, through mother abdomen skin, fat, water and oxygen inside the uterus, to the fetal ear. Therefore, the treble to the fetus, much smaller than the actual sound is much lower,. Submersible in water, the outside voice low, as if you were locked up the door to listen to the sound. Terminology this is called \"high-field decay\".
Represents the height of the sound in Hertz units. This is called the frequency, that is, number of Sonic vibration. 1,000 hertz vibration 1,000 times a second, transmit sound frequencies. Opera soprano voice, generally the equivalent of 2,500 to 3,000 Hz, its frequency is high. However, fetuses are not good at listening to the treble, cannot be heard above 3,000 Hz treble. Of course, even the treble, through mother abdomen skin and becomes quite low after the amniotic fluid. So that you can say, you can hear sound. However, the fetus is also love to hear voices. Fetal good at listening to audio of 200 to 1,000 Hz. The intensity of the sound coincides with mother\'s voice. Fetal often listen to the mother\'s voice, feel comfortable.
To find out how the fetus hears the sound of someone did an interesting experiment. Japan National Okayama hospital in the mountains of Yi lang MD, drank hundreds of ml of beer, drinks on the small microphone when coated with lots of butter, place a microphone in the stomach is full of beer, butter, dissolve, water viscosity. Its the same as womb full of oxygen water. TV, record how to transfer the music in the womb, recorded on this.
Results known, transmission of sound in the stomach is very appropriate. Treble becoming slightly lower, how sounds are not tone sandhi. This experiment confirmed that outside voice can properly reach the fetal ear.

A woman, with the doctor in the mountain recorded his voice in the same way. Tone sandhi is very ill, but sound intensity is recorded correctly. In particular, \"no\" that reprimands recorded sound was clearly down when. This suggests that even if the fetus does not know the meaning of language, but the mother the sound intensity, can be sensitive to feel the mother\'s mood. To not make the fetal heart, mother softly and calmly talking to key.
