简介
I often hear people say, "If you listen to this music, you will sleep well," but I'm not sure that the music is perfect for sleeping. However, it has been found that "white noise" has a certain effect on sleeping young children. White noise is the rubbing sound of "Za" or "Go" like a sandstorm on TV. The sound of rain and waves is also included in white noise. According to one theory, this is similar to the sound of the mother's blood flow that the child heard in the stomach, and it is thought that it gives a sense of security.
