Another study found people who used it slept more deeply. Studies are limited, but pink noise may also boost your memory. A recent study found that older adults who used it at night did better on memory tests the next day. We need more research to find out how pink noise affects your sleep, focus, and memory.
One study suggests that pink and red noise are best for concentration and work performance. Brown noise, on the other hand, has been popular on social media in recent months, but there isn't enough research on this color specifically to know if its effects are better than that of red, white, or pink noise.
The best sounds to listen to when studying include classical music, white noise, and nature sounds.
There are even brown noise playlists curated with babies in mind because it's said to mimic the sound inside a mother's womb. There's also potential beyond relaxation. Some small studies have shown that auditory noise can help to improve memory in children with ADHD.
Brown noise is a low-frequency background sound that helps people with ADHD focus and feel calm.
For example, listening to binaural audio, background music without vocals, or chill electronic music like lo-fi hip hop can help ADHDers with focus and concentration. On the flip side, there are some genres that might do the opposite.
Use of violet noise:
The high frequency can be distracting to rest. However, this noise is great for treating people with conditions like tinnitus. Tinnitus is when people hear ringing in one or both of their ears. Violet noise can help mask the ringing sound.
Over the last 20 years, scientists have uncovered evidence that immersive sounds like white, brown and pink noise may help the brain to focus, sleep or relax — especially for people with A.D.H.D.
Gray noise is similar to pink noise in that it sounds the same at every frequency. It has equal strength over every frequency which is pleasant to the human ear. Gray noise is used to treat hyperacusis (intense sensitivity to everyday sounds,) and tinnitus (ringing in the ears.)
But it appears brown noise is considered the most beneficial for people with ADHD because it stimulates the part of the brain that is hypo-aroused. This allows people with ADHD to pay more attention, find a state of relaxation, and calm the hyperactivity they experience.
All sounds possess different characteristics and purposes, however. Generally, white noise is better for focus and productivity, while ambient noise fosters creativity. Ambient sounds can range from flowing waterfalls to the steady hum of life in a coffee shop.
Short for Brownian noise, but also known as red noise, this type of sound is often used while studying or exercising to help the brain and body work at its best. It's ideal for those who are easily distracted from their usual music, and just need something light to create a peaceful backdrop to study to.
White noise: for focus. Brown noise: for calm. Pink noise: for sleep. Green noise: for studying.
People who find their focus or concentration improves with low-level background brown noise may just be benefiting from “sound masking”: “The sound blocks out other sounds so you're less distracted.” This is probably also why people report improved sleep with brown noise.
Green noise can benefit a wide range of individuals, including those with sleep disorders, anxiety, and stress. People who have trouble falling or staying asleep due to environmental noise or racing thoughts can benefit from green noise, as it can mask unwanted sounds and promote relaxation.
More recently brown noise gathered attention that this may be helpful for ADHD symptoms and sleep. Brown noise is mainly using lower frequencies, creating lower-pitched noises that sound more pleasant to some.
Green noise is around a frequency of 500 Hz, Huffington Post reports. Brown noise has a lower, deeper vibe, though it still contains every frequency like white noise. The New York Times describes it as soothing, steady, and rumbly, and notes that it made waves in online ADHD communities in 2022.
More and better research is needed, but some studies suggest that white noise can help people with ADHD with some cognitive abilities; white noise and pink noise may help improve sleep; and brown noise may help with concentration and relaxation.
Pink noise, white noise or any type of sound is generally safe for anyone to use. It helps you sleep by covering up distracting sounds that might disrupt your snoozing. “That consistent noise creates a masking effect that blocks out sudden noises that might cause you to wake up,” explains Dr. Drerup.

White noise for sleep
The consistency of white noise creates a tried-and-true masking effect, which can help people fall asleep faster.
Pink noise and brown noise
Pink noise has some of the higher-pitched tones removed. Brown noise is more of a deep rumbly sound and is my personal favourite to listen to as I fall asleep. White, pink or brown noise may not only block out household noise but can help your child to relax and fall asleep.
Studies have indicated that brown noise can help people manage anxiety and sleep longer. It makes them less reactive to ambient sounds, and that helps them fall asleep and also to concentrate better, says neurophysiotherapist Dr Himani Dalmia, co-author of the book Sleeping Like A Baby.
