Many of us like to fall asleep to the sounds of a white noise machine, but according to TikTok, brown and pink noise may be the sleep aides of the future. The hashtags #brownnoise and #pinknoise have already racked up more than has over 175 million posts.
Brown Noise
Brown noise contains sounds from every octave on the sound spectrum; however, the “power behind frequencies decreases with each octave.”Pink Noise
Pink noise, explained Today, “has a decreasing high frequency and sounds like gentle rain or a waterfall.”While pink noise isn’t as low as white noise or as deep as brown noise, it’s still great for helping someone fall and stay asleep. This type of noise settles in the middle with “softer, quieter, and more flat” tones.
According to sleep experts, this new TikTok trend might be onto something as pink and brown noise can be helpful depending on the person and the type of sleep help they need. A study by Dr. Phyllis Zee, professor of neurology at Northwestern University Feinberg School of Medicine, found sleeping with pink noise improves sleep quality and memory.
“The effect here, at least for memory, is quite related to the ability of the sound stimulus to enhance slow-wave sleep,” Zee told TIME. “That’s very much tied to what part of the slow wave the stimulus is hitting on.”
Siest Sleep explained that brown noise can “clear your mind of chatter and calm your mind before sleep. Also, they help mask other sounds so your brain is not interrupted when you sleep.”
