In a world where white noise has long been the go-to for masking background sounds, a new trend is emerging – the colourful competition of pink, brown, and green noise. These soothing sounds are gaining popularity for their potential effects on sleep, concentration, and relaxation.
While the science behind these colour noises is still in its infancy, thousands of people are turning to platforms like YouTube and meditation apps that offer a variety of colour noises with paid subscriptions. From pink noise, which tones down harsh high frequencies to create a calming effect similar to rain or ocean waves, to brown noise, with its deep, rumbling pitch, these colour noises are capturing the attention of many.
Recent studies have suggested that white and pink noise may provide benefits for individuals with attention-deficit/hyperactivity disorder (ADHD) by stimulating the brain without causing distraction. Additionally, researchers at Northwestern University are exploring how short pulses of pink noise could enhance deep sleep and improve memory.
While the potential benefits of colour noises are promising, experts advise caution in their use. It is essential to keep the volume at a safe level to prevent hearing loss and take breaks to allow the ears to rest. As research into the effects of colour noises continues, it remains to be seen whether these vibrant sounds will become a staple in the quest for better sleep and concentration.
