In addition to the standard white noise, there is pink, brown, purple, and green noise. A growing body of research shows that these little-known color noises can help stabilize mood and improve sleep quality.

New York, NY (Merxwire) – We call disliked sounds noise, but not every noise is unwelcome, and more and more people like to sleep with white noise when they sleep. Moreover, in addition to white noise, scientists have also found that pink noise can help deep sleep and improve memory.

A study found that people were better able to fall into a deep sleep when accompanied by pink noise. Deep sleep is closely related to memory. As we age, memory declines due to erratic sleep quality. But scientists found that older adults who used pink noise slept better and performed better on memory tests the next day. Moreover, in another study of young adults, people who listened to pink noise during their lunch break performed better on verbal memory tests than those who didn’t.

What is pink noise? “Pink noise,” called 1/f noise, combines high and low frequencies. It is commonly found in nature, such as in the sound of wind, rain, or waterfalls. Due to how the human ear works, pink noise is thought to have a pleasant and balanced function at different frequencies.

In a quiet environment, even the tiniest sound can be detected, like black dots on white paper, very obvious. But if it is a mess of multi-color, this small black spot is not easy to find and is cleverly hidden in the background. The same goes for the sound. Pink noise can mask other sounds and distract from ambient noise, which relaxes the brain and reduces stress.

However, it is worth noting that not all noises have helped to sleep. Loud, harsh, or uncomfortable noises may affect physical and mental health and cause hearing loss, so we must be careful.
