You’ve probably heard of white noise—that steady, static-like sound that helps block out annoying noises and can even improve sleep. But what about pink noise, brown noise, or even green noise? Turns out, these lesser-known sound types might also help you relax and sleep better. Let’s break it all down and see what these “color noises” are all about.
White Noise: The OG of Sleep Sounds
White noise is the most popular type of color noise. It’s a mix of all the sound frequencies we can hear, playing at the same intensity. Think of it like the sound of a fan, an air conditioner, or even a vacuum cleaner—it’s that consistent, static-like hum.
Research suggests white noise might help with:
- Better sleep
- Calming crying babies
- Boosting focus at work
- Easing ADHD symptoms
While a lot of people swear by it, experts say we still need more studies to fully understand its effects.
Pink Noise: The Soothing Alternative
Pink noise is like white noise’s calmer cousin. It’s deeper and softer, with lower frequencies that make it more relaxing. Imagine the sound of steady rain, rustling leaves, or gentle ocean waves—that’s pink noise. It’s great for drowning out higher-pitched distractions, like chatter or traffic, so you can drift off more easily.
Some studies even suggest pink noise might help with memory, especially for older adults, but we still need more research to know for sure.
Brown Noise: The Deep, Rumbly Option
Brown noise (sometimes called red noise) takes things even deeper. It’s got a bass-heavy, rumbling quality, like the sound of heavy rain or a strong waterfall. Some people find it super calming, and it’s even been used to help with tinnitus (that annoying ringing in your ears) and to boost focus. But, like the others, we need more research to fully understand its sleep benefits.
Green Noise: Nature’s Lullaby
Green noise is like the Goldilocks of color noises—not too high, not too low, but just right. It’s a mid-frequency noise that mimics the soothing sounds of nature, like a babbling brook, gentle wind, or rustling trees. It’s not as sharp as white noise or as deep as brown noise, making it a great middle ground for people who find other color noises too intense.
Green noise is perfect for creating a calming, natural ambiance, and it’s especially helpful if you’re looking to relax or meditate. While research on green noise is still limited, many people find it incredibly soothing and a great addition to their sleep routine.
Other Noise Colors? Yep, They Exist!
Beyond white, pink, brown, and green, there are a few other “color noises” out there:
- Blue Noise: Sharper and higher-pitched, like the sound of a water spray.
- Violet Noise: Even higher-pitched, often used for tinnitus treatment.
- Grey Noise: A balanced mix of high and low frequencies, kind of like a more even version of white noise.
Can These Noises Really Help You Sleep?
For a lot of people, white noise is a game-changer for sleep because it masks disruptive sounds. One study found that 38% of people fell asleep faster with white noise.
Pink noise, with its deeper tones, can help soften the difference between quiet background sounds and sudden loud noises, which might help you sleep more deeply. Some research even suggests it could lower brain activity during sleep, leading to more stable rest.
As for brown noise, the evidence is still thin, but some people find its deep rumble super relaxing.
Green noise, with its natural, mid-range frequencies, is perfect for creating a peaceful environment that feels like you’re sleeping in the middle of nature. It’s especially great if you’re looking for something calming but not too overpowering.

Tips for Using Color Noise Safely
Not all sounds work for everyone, so experiment to find what you like best. If wind sounds stress you out, try rain or a babbling brook instead. Adjust the volume to a comfortable level—it shouldn’t be too loud.
If you’re using headphones, go for something comfy, like earbuds or sleep-specific headphones.
Pair Color Noise with Good Sleep Habits
While pink noise (or any color noise) can help you fall asleep faster and sleep deeper, it works best when combined with healthy sleep habits. Here are some tips:
- Stick to a Sleep Schedule: Go to bed and wake up at the same time every day, even on weekends.
- Get Moving: Regular exercise can help you sleep better at night.
- Set the Scene: Make sure your bedroom is dark, quiet, and cool.
- Avoid Sleep Killers: Skip caffeine, alcohol, and heavy meals before bed.
By combining these habits with the right color noise, you’ll be on your way to better sleep in no time. Sweet dreams!
