The human brain has a clear division of labor, but the left brain is more developed than the right brain after birth. Developing the right brain with prenatal music can balance the development of the left and right brains as much as possible. Music is transmitted to the immature brain of the fetus through the maternal nervous system, which has a favorable impact on the development and maturity of the fetus. Well, when the baby is in the mother's belly, the auditory system develops well. Listening to prenatal music for babies now is an early education, which can promote good communication between babies and mothers. Fetuses should listen to prenatal music for no more than 20 minutes at a time, 1-2 times a day, and play it with a tape recorder, with a sound intensity of 6570db at a distance of 1.5-2 meters.
If parents are more careful, they can also carry out targeted prenatal education. For example, pregnant mothers feel that the fetus in their bellies is full of vitality, so they can listen to some music with slow rhythm and soft melody, just like lullaby. If you can hear Mozart's music during milk production, if you are not a pregnant mother or a cow mother who has just given birth, the milk production will increase greatly. This has been confirmed by scientific experiments, which is the so-called "Mozart effect".
Just like the sounds of rivers and streams, insects and birds in nature, classical music (especially baroque music), because its rhythm is similar to the mother's heartbeat, can illuminate and appease the fetus and newborn. Therefore, pregnant women should control the audio frequency below 2000 Hz when choosing music, and control the volume below 85 dB when listening to music.
