[What is white noise?]
White sounds around our lives include the sound of rain, the sound of waterfalls, the sound of waves, the sound of streams, and the sound of tree branches rubbing in the wind. Since these sounds are the everyday sounds that we usually hear, even though these sounds are heard as noises, we hear them without being aware of them psychologically. Also, because it is a natural sound that has always been heard, you feel a sense of stability in the sound. In addition, the white sound of nature gives us a sense of protection that we are surrounded by the surrounding environment as a member of the universe, so that the listener can audibly relieve the sense of silence.

Through various experiments over the years, I have found that noise can also be a relief. First, in the office, without knowing anything, white noise was heard about 10 decibels (dB) higher than the normal ambient noise, and after a week, small talk and unnecessary body movements during work were significantly reduced. After a month, the white noise was turned off, and the concentration of work fell drastically as each other became bored. In other words, having some rather than no white noise increased work efficiency.
It is said that if you are pitching a tent on the beach in summer, you will feel cool and cheerful by the blowing sea breeze, but you will sleep deeply in the sound of the crashing waves. Particularly in Japan, the sound of the waves of Okinawa's beaches is recorded on CDs and sold, and it is said that it is very popular for inducing a good night's sleep when citizens take a rest in a sleeping capsule in the city center. This is because the white noise hidden in the sound of the waves synchronizes the alpha waves of human brain waves to stabilize the mind and body and promote sleep.
In addition, the learning effect is greatly improved when students hear the white sound of nature. A test for memorizing English words was conducted for male and female middle school students at a tutoring academy located in Nowon-gu, Seoul. They were asked to memorize completely new 2nd grade English words for 5 minutes according to their normal conditions and the condition when they heard white sound, and their academic achievement improved by 35.2% compared to usual.
Another experiment was to find out how much improved concentration when listening to white noise in the reading room. I attached a device that generates white noise on each desk, and while studying, I compared and grasped the number of times I turned my head to the seat next to me or paid attention to the surroundings by time. Even in this case, when white noise was heard, the number of times of interest in the surroundings decreased by about 22%.

In another experiment, we observed the change in concentration when we heard the natural sounds around us. Various sounds around him were heard every 5 minutes, and movements of the body were observed during study by age group such as teenagers, 20s, and 30s. Subjects in their teens and twenties preferred the sound of a relatively wide pitch, such as the sound of dripping water and the sound of a shower, and the concentration of study increased. On the other hand, people in their 30s prefer medium-range white noise, such as the sound of a small rain or a large stream, and have an effect of increasing work concentration.
On the other hand, if a newborn baby under 3-4 months of age is crying, will the baby be calm if the sound of heartbeat, breathing, and voices of mothers and fathers are recorded and heard, which would be heard during fetal days? However, as a result of the experiment, the baby was more and more anxious and only crying more anxiously in search of the mother's arms.
At this time, if you hear the hissing noise from an empty TV channel, the crying baby immediately stops crying and finds a sense of stability. Some parents say that the crying baby has found rest when he hears the sound of the vacuum cleaner, and when he hears a rustling sound while fiddling with a soft plastic bag, the baby quickly makes a bright expression. These sounds that soothe newborn babies are also artificially made white noise.
