Young mothers, exhausted by the crying of a baby, delightfully tell each other about the “white noise”,which magically helps the baby to calm down and sleep. What is this noise, how does it act on a baby? In what cases does it really help, and in what cases is it useless?
White noise is a mix of sounds of different frequency and intensity.. An example is the sound of sea waves, a powerful stream of water from a tap, the hum of a hair dryer or a vacuum cleaner. Such an even noise background reminds the child of the situation in which he was from the moment of conception. In the uterus was surrounded by water, blood circulated in the vessels of the placenta. This sound, which would remind us of the splash of water, surrounded it around the clock, without interruption. After birth, the baby got into a completely different situation, the sounds in it are much more diverse: from complete silence to rumble and screams. On the background of this unusual diversity, an even monotonous “white noise” is strongly associated with the peace and security of my mother's tummy.
Many adults also notice how the sound of sea waves has a relaxing effect on them., the murmur of the river or the sound of rain outside the window. All of this - the echoes of our intrauterine life.

Usually mothers notice how white noise acts on a child, quite by accident. To the sounds of a working hair dryer, or during cleaning, when the vacuum cleaner was buzzing, the baby suddenly calmed down and even fell asleep. This method works great if the child is tired, over-excited, scared, or restless for some other reason. Even more effectively, the noise will act if you wrap the baby in a cozy cocoon from a blanket so that he feels the “walls of the uterus” around him.
If crying is caused by hunger,illness or physical discomfort, for example, the baby crushes the blanket, or it's time to change the diaper, the noise does not help. It is necessary to solve a physical problem, and then calm it down psychologically.
Do not abuse the white noise.It is worth using it only for a few minutes, at the time of falling asleep, to calm and relax the baby. When he falls asleep, the sound needs to be turned off.
Comfortable noise for a child - about 50 dB.By volume, it resembles the sound of water in the shower, or the rain outside the window. Loud sounds will negatively affect the development of children's hearing.
