White, Pink, and Brown Noise. What’s the Difference?

Almost every single person has suffered from insomnia at least once in their life. There are tons of factors that can cause it, including:

  • eating a heavy meal too close to bedtime
  • work stress 
  • taking certain medications
  • sleeping in uncomfortable conditions
  • watching television or using your cell phone right before bed
  • jet lag
  • drinking alcohol or caffeine in the evening
  • chronic pain
  • and more…


If you’ve struggled to fall asleep, you’ve probably also tried using a white noise machine that plays sounds like gentle ocean waves, soft rain, or humming nature to help you rest. This not only can help you sleep, but help you stay asleep, especially if you’re lying next to a snoring partner, or live in a loud city where honking horns or loud traffic are inevitable. White noise helps buffer the sounds that may otherwise wake you up, allowing our brains to remain relatively undisturbed at night. White noise is also widely listened to during daytime hours as it’s been scientifically linked to enhancing concentration and focus. But did you know that there are other sonic hues such as pink and brown that also have amazing calming benefits?


The problem with white noise is that all the frequencies come through at the same intensity. Human ears tend to be adverse to high-pitched sounds, so some white noise can actually be more annoying than soothing. Pink noise is a lesser-known, softer, milder version of white noise that emphasizes lower-frequency sounds. Thus it’s gentler on your ears, and more likely to help you stay asleep, rather than being startled awake by a sudden spike in the frequency of white noise. Several studies have shown that people who fall asleep listening to pink noise have improved memory the following day, and potentially even long-term. 


Lastly, brown noise produces a rumbling sound with a deeper, bass-like tone than pink or white noise. It’s a bit rougher than pink noise and resembles a roaring river or gusty wind. There is scientific evidence indicating that brown noise can lower symptoms if you have ringing in your ears. It’s also shown to improve your cognitive skills.


While much more research is needed, the general consensus is that all sound hues can help us:

  • fall asleep faster
  • stay asleep longer
  • feel calmer and more focused


So will white, pink or brown noise help you sleep better? The answer all comes down to personal preference, so give each of them a try and see which works best for you!
