What is brown noise? TikTok suggests it's better than white noise.

White noise has been a trustworthy aid for a variety of reasons, such as meditation, studying, sleeping with insomnia, and helping young children (and their parents) fall asleep faster. After stumbling across #brownnoise TikTok, however, I may never go back to white noise again.

Whereas white noise encompasses sounds from all over the spectrum, including low, mid-range, and high frequency notes, brown noise uses only low frequency and bass-heavy notes. This makes brown noise much deeper in sound than white noise and more ideal for those who find the high frequency notes in white noise uncomfortable. Both can occur naturally in nature: Gentle rain showers and crashing waves are examples of white noise, while thunder and strong winds are examples of brown noise.

TikTokkers, especially those with ADHD, have been raving about the benefits of brown noise as opposed to white noise. While previous studies have shown the benefits of white noise on cognitive performance and verbal working memory in ADHD, the effects of brown noise are relatively understudied. Some people find that brown noise is more effective in quieting thoughts, allowing for better focus and productivity. Others prefer it to white noise for sleeping, or simply for the calming effect.

I suffer from bouts of tinnitus and the high frequency notes in white noise can often make it worse. So far, brown noise has helped distract me from uncomfortable tinnitus sounds. And I’m not the only one who finds comfort in brown noise: I’ve found that my cats seem to prefer it for the low frequency rumbles as well.

If you’re not a fan of brown noise or white noise, don’t despair! There’s also pink noise, blue noise, violet noise, and gray noise, all of which operate on different frequencies. Ready to hear what all the hype is about? Here are a few apps you can use to play noise:
