Not everyone will want to sleep to noise. That “conditioning” and what you are used to will play a role in what you find comforting and relaxing for sleep, Purdy explains. If you don’t have any issues sleeping, you might even prefer pure silence. If you grew up on a busy city street, you might find much more comfort in the sounds of traffic, including car engines and beeping. Who Might Benefit the Most From “Color” Sounds for Sleep Researchers also pointed to pink noise for shaving minutes off that dreaded “trying to fall asleep” period, and also noted that brown, purple, and blue noise (additional types of frequency combinations) might help you fall asleep, though those have less research backing them up.Īnother study showed pink noise to be the most helpful, and even suggested that beyond uses for sleep, color noises might be potentially helpful in workplaces to improve productivity. There are studies supporting each type of noise’s efficacy, such as a 2022 study revealing that white noise significantly reduced the time it took participants to fall asleep by 38 percent, compared to normal environmental noise. Purdy adds that brown noise can sound a bit more “coarse” than pink noise, likening it to a strong wind or rushing river. In contrast, “Brown noise has some emphasis on the lower frequencies and minimizes the higher frequencies even more than pink noise does,” she explains. Some people find pink noise to be a little bit more soothing than white noise, because those high-pitch frequencies are reduced,” says Purdy. “The difference between pink and white noise is that pink noise has some of the higher frequencies reduced and so it sounds a little lower pitched if you are listening to it compared to white noise. Choosing the best color for you might take some trial and error, and a bit of understanding as to what you are hearing exactly. Which Type of Noise Will Put You to Sleep?Ī quick scroll through your device’s sleep sound options will reveal a whole rainbow of colors you can fall asleep to. Laura Purdy explains green noise as “ambient noise in nature, so some people do find it more soothing than brown noise.” She adds that it sounds distinct from other colors of noise, and is therefore more relaxing for troubled sleepers. Psychologist and primary care physician Dr. The New York Times describes it as soothing, steady, and rumbly, and notes that it made waves in online ADHD communities in 2022. Green noise is around a frequency of 500 Hz, Huffington Post reports.īrown noise has a lower, deeper vibe, though it still contains every frequency like white noise. White noise typically sounds like an air conditioner, vacuum, fan, or even an airplane engine, while green noise, a type of white noise, might remind you a bit more of soothing nature sounds from wind to water. White noise, more broadly, contains all frequencies found in the spectrum of sounds that you can possibly hear, with equal parts of each, WebMD reports. It reminds people of nature more than other frequencies (hence the description “green noise”). Green noise is a frequency of white noise. Though research is still limited on the impact of trending green noise, sleep scientists do already know quite a bit about the power of noise for sleep, and how to determine which type is best for you. Another Tik Tokker calls it a “game changer” for those with trouble sleeping.īut all these colors of the rainbow can have your head spinning on just what noise is best for sleep, and in particular your own sleep issues. These aren’t the kind of nature sounds that have you waking up wondering if there’s a coyote in your closet or an owl at your window, but instead an even and consistent ocean-like sound, much more similar to other types of noise such as pink or brown. You’ve turned to Tik Tok for the latest makeup hack, parenting advice, and hilarious puppy videos - but now troubled sleepers are looking for solutions in Tik Tok’s favorite new sleep sound, “green noise.” In one video, with an enviable green ocean in the background, we learn that green noise is in the middle of the frequencies of white noise, and has a “calming effect” for some because it “sounds like nature.”
