Does pink noise improve memory and sleep quality? An early study creates a buzz about colour noise.

White noise is sometimes employed to muffle background noise, as you may have heard. It faces colourful competition now.

The use of pink, brown, and green noise—a rainbow of calming noises—and their potential benefits for improving sleep, focus, and the relaxation response are becoming more and more popular.

Thousands of individuals have been listening to hours of these noises on YouTube and on meditation apps that offer a palette of colour noises with paid subscriptions, despite the fact that the science behind them is still relatively new and only a few tiny studies have been conducted.

PINK NOISE: WHAT IS IT?

White noise is the most recognisable of the colour noises, so start there to comprehend pink noise.

White noise is comparable to TV or radio static. It has identical loudness throughout all frequencies that are detectable to the human ear, according to sound engineers. White light, which consists of all the visible colour wavelengths, is where it gets its name.

However, white noise’s high frequencies can have an unpleasant sound. Pink noise reduces the intensity of the higher frequencies, producing a more subdued sound that resembles the sound of the ocean or rain.

Brown noise has a pleasant, calming rumbling and is even lower in pitch.

Similar to white, pink and brown are commonly understood by audio specialists. More contemporary inventions with extremely nebulous descriptions are other colour sounds.

WHAT SCIENCE IS ACTIVATED BY COLOUR NOISES?

A recent assessment of the few studies on ADHD found that pink and white noise may have little benefits for those with attention-deficit/hyperactivity disorder. Joel Nigg, a co-author and researcher on ADHD at Oregon Health & Science University in Portland, explained that, in theory, it awakens the brain.

“The noise doesn’t distract because it stimulates the brain without giving information,” according to Nigg.

Tinnitus, or ringing or buzzing in the ears, has been treated with white noise.

Northwestern University researchers are looking at how pink noise pulses, even brief ones, can improve deep sleep’s sluggish brain waves. These pink-noise pulses have demonstrated potential in enhancing the relaxation response and memory in limited trials.

Because pink noise is made up of massive, slow waves, its frequency profile is “very similar to the distribution of brain wave frequencies we see in slow-wave sleep,” according to Dr. Roneil Malkani, an associate professor of neurology at Northwestern University Feinberg School of Medicine.

Should Northwestern University’s research be successful, individualised pink noise pulses could be used in a medical gadget to enhance memory or sleep. Malkani noted that there are still a lot of unsolved scientific questions. “We still have a lot of work ahead of us.”

IS IT HARMFUL TO TRY COLOUR NOISES?

Using colour noises makes sense if they help you block out distractions and feel soothing. Naturally, keep them quiet to avoid hearing loss, and give your ears “plenty of breaks to rest,” according to Nigg.
