Description
Technical Field
The present invention relates to the field of data processing, and more particularly, to a method and an apparatus for making music for soothing an infant, a computer device, and a storage apparatus.
Background
About 40 weeks from the formation of the zygote until the birth of the fetus, this stage is called the fetal stage. When the development of the fetus reaches 20-28 weeks, namely 5-7 months, the hearing of the fetus is completely formed, various sounds can be distinguished, and corresponding responses can be made in the uterus according to the sounds.
The sounds of the mother's body that the fetus can hear in the uterus include heart beat sounds, bowel sounds, own heart beat sounds, amniotic fluid sounds during fetal movement, the sounds of the mother speaking and the like, wherein the bowel sounds, the amniotic fluid sounds and the sounds of the mother speaking are random sounds without any regular frequency. The mother's heartbeat sound is periodic and regular, and is easier for the baby to remember.
Infants are often easy to be irritated due to lack of safety sense, and the situation that the infants are difficult to fall asleep is very easy to occur. In this case, if a sound similar to that familiar to the baby in the uterus can be played, an environment with a sense of security can be created for the baby, so that the operation intensity of soothing the baby by the mother or soothing the sleeping baby can be reduced. For mothers who are weak and have limited energy and physical strength during lactation, the nursing baby bed can have better rest time and well reduce the strength of nursing babies.
The environmental sounds with which the infant is familiar in the mother include the heart beat sound of the mother, the amniotic fluid noise of the uterus, the fetal heart sound of the fetus itself, and the like. In order to still hear these familiar sounds after the birth of the infant, it is necessary to develop a soothing music synthesis method that synthesizes the sound environment of the uterus of the fetus.
