※ Effects of white noise

White noise began to receive attention when ‘ASMR’ became a hot topic on the Internet. According to a study by the Korean Society of Industrial Psychology, white noise was found to improve concentration by 47.7% and memory by 9.6%.

Stress can also be reduced by 27.1%, and it has the effect of shortening study time by 13.63%, so white noise is becoming widely known, especially among studying students. Previously, there was a perception that ‘noise’ was simply a sound that was loud and made people feel uncomfortable. However, white noise is a natural sound that we have always heard, and it serves as a so-called ‘good’ noise for the ears because it brings psychological stability and concentration.

The secret to why white noise helps increase concentration lies in its frequency. White noise has an overall uniform and constant frequency range, which actually serves to cover up surrounding noise.

It is known that because it is easy to get used to the ear, it is not considered noise and rarely interferes with work. Simply put, rather than having one specific hearing pattern, it is accepted as an overall noise level.

Of course, excessive white noise has negative effects. However, most studies show that moderate white noise has positive effects. Great Ormond Street Hospital in London, England, also announced the medical effects of lullabies.

At this hospital, 4 lullabies, including ‘Little Star,’ were played to 37 hospitalized patients under the age of 3, including a critically ill baby waiting for a heart transplant. As a result, one infant suffering from tachycardia was observed to have a heart rate that slowed down to close to normal.

Additionally, children who cried or grimaced due to pain showed signs of relief. This was a response when a song with a melody was played, and it was found that children responded more to songs played vocally.

The sound of the mother's heartbeat and the sound of blood flowing in the blood vessels, heard while in the mother's womb, becomes white noise with a certain frequency, which gives children a sense of psychological stability and helps them fall asleep naturally.
