What Pink Noise Can Do For Your Brain
Growing up, it was common to leave the T.V. set on to the static white noise as I slept. The static noise was set on low but it was just enough to set the ambience. Many of us are familiar with this scene or have at least one family member that does this. What many of us know as white noise also comes in different colors, like pink and blue and it turns out, each color serves a purpose to influence our senses in a remarkable way.
Pink noise comprises of low and high frequencies. It is a balance version and a bit softer version of white noise. This means it is less harsh and ideal for ambience when you are trying to snag some sleep. To put in an audio perspective, pink noise sounds like the smooth, gentle waves of the ocean or a soft rustling of leaves.
The connection between sleep and memory has caught wind in the research community in the past recent years. Many of the researchers believe that pink noise has the potential to improve our memory by affecting our brain function as we sleep. To put substance to the belief, a study conducted the effect of pink noise on adults and found that it did improve memory which can be crucial for cognitive function.
Deep sleep is known as Slow Wave sleep and it is considerably important when it comes to memory function and the aging process. The purpose of the study was to analyze the link between cognitive function using pink noise and slow wave sleep. The pink noise was used in intervals to increase Slow Wave Activity throughout the subject’s sleep. The objective was to observe whether or not the sound of pink can transform the brain activity and assist with memory the following day.
In the study, a total of thirteen people from between the ages of 60 and 84 were exposed to one night of acoustic stimulation and one night of placebo stimulation. A survey of memory was tested before and after sleep in addition to a recording of brain activity during the night. The results demonstrated that the Slow Wave activity significantly increased on the nights of the acoustic stimulation as compared to the night of the placebo stimulation. The scientists were able to concluded that Slow Wave activity and memory storage can be enhance by delivering pink noise at the correct time.
As we age, succumbing to memory loss is inevitable as the cognitive function declines. Studying the beneficial effects of pink noise has brought hope as the study addressed an issue prevalent among its subjects. But, the welcoming effort doesn’t stop there! Younger people are able to take advantage of the same benefit as well with memory retention being a notable effect. If you are having trouble sleeping and are interested in experimenting on your own, I recommend looking up on YouTube for a reputable audio of pink noise before a deep slumber.
