The fetus is protected by amniotic fluid, fetal heart and placenta, and the external sound is absorbed by these protective layers, so the sound the fetus hears is not very loud. Pregnant women need to let nature take its course. If there are no other abnormal symptoms, no special treatment is needed. Women should stay away from radiation as much as possible after pregnancy, use less mobile phones and computers, and watch less TV.

Under normal circumstances, the pregnancy time of the fetus is generally 42 weeks. During the 42-week period, pregnant women need to go to the hospital for regular check-ups according to the doctor's requirements. It is recommended to minimize activities and stay in bed in the first trimester. At the same time, we need to pay attention to the collocation of diet to ensure a healthy diet.

Fetal hearing formation time

Fetal hearing can generally be formed in about 6 months. After pregnancy, the fetal eardrum is usually formed in about 3 months, which is a critical period for cochlear development. The development of middle ear and tympanum is basically completed, and the hearing is basically achieved.

Among the fetal sensory organs, hearing is relatively developed and gradually formed. 12 weeks later, nerve cells will begin to develop, and various organs in the body will also mature. By about 6 months, he can hear his mother's heartbeat and voice, and he will react to all kinds of voices from outside. At this time, prenatal education can also be carried out through music.
