According to the results, white noise is an effective nonpharmacological method to control pain, reduce crying time, and positively affect vital signs. It is well-known that any human action results from brain activity, which is affected by light and sound.
Exposure to the color blue is able to lower heart rates and metabolisms and is used to treat pain.
Pink noise is white noise, but with reduced higher frequencies. It resembles the sounds of steady rainfall or wind and is often considered to be more soothing than white noise, which some people find unpleasant.
People with anxiety tend to be on high alert... The use of pink or brown noise may reduce their reactivity to those little sounds in their environment and support calming, sleep, or even concentration. The frequencies picked up in pink noise fall between white and brown noise and are also thought to aid in sleep.
Violet noise.
Also called purple noise, it's the opposite of brown noise. The volume goes up when the frequency does and it gains power faster than blue noise. It's one of the higher-pitched color noises. It's often used to treat tinnitus, a condition that causes loud ringing in one or both ears.
Pink noise is often used as a background or control noise because research has found that it is less distracting than other types of noise. For example, one study found that participants became less stressed after listening to pink noise, compared with the typical sounds of an intensive care unit.
Red noise, also known as Brownian noise or brown noise, is a type of signal or data that follows a random pattern. It is a type of ambient noise generated by electronic devices and is often used for testing purposes in fields such as acoustics and telecommunications.

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.
Similar to white and pink noise, brown noise is useful for masking distracting sounds. Opt for brown noise, however, if those sounds are a bit lower in pitch. In a 2018 study published in Frontiers in Psychology, brown noise was also shown to support the transition into REM sleep for some.
In audio engineering, electronics, physics, and many other fields, the color of noise or noise spectrum refers to the power spectrum of a noise signal (a signal produced by a stochastic process). Different colors of noise have significantly different properties.
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.
Studies dating back decades have shown that music and other kinds of sound can help alleviate acute and chronic pain in people. This is true for pain from dental and medical surgery, labor and delivery, and cancer. However, how the brain produces this pain reduction, called analgesia, was less clear.
If you're not sensitive to high-pitched sounds, blue noise does a great job of heavily masking outside noises. It's harsh at loud volumes, but audio engineers often use blue noise for dithering, a process where they intentionally add noise to a production, such as a song remix, in order to smooth out the sound.
“People feel calm and focused with some pleasing ambient sounds. Brown noise triggers relaxation because of its similarities to the brain's resting state. Its lower frequency creates a deeper sound that helps people relax,” she says.
Pink noise, which picks up frequencies in between white and brown noise, is believed to assist in sleep. Some people find it more restful than white noise, because it contains deeper sounds than white noise. Research has shown that listening to pink noise at bedtime led to more peaceful sleep.
Does Noise harm your Brain? Well yes. It turns out, the continuous background noise also known as white noise which comes from machines and other appliances, can harm your brain, it does so by overstimulating your auditory cortex– the part of the brain that helps us perceive sound. And it's even worse in children.
Purple sounds like a grape erupting in your mouth, with a hint of lavender.
Examples of pink noise include steady rainfall, waves, and rustling leaves. Research indicates that both white noise and pink noise may have beneficial effects on sleep.
It can also help you fall asleep — or fall back asleep — after waking.” Certain kinds of noise might also affect you physically. In one study, pink noise increased deep sleep and improved memory in older adults. Using pink noise on a consistent basis can also lead you to associate pink noise with falling asleep.
Brown noise is a low-frequency background sound that helps people with ADHD focus and feel calm.
Pink noise is a category of sounds that contains all the frequencies that a human ear can hear, or 20 Hz to 20,000 Hz, says Iris Langman, MSPA, a clinical audiologist at the UW Medicine Northwest Outpatient Medical Center. Although pink noise contains all of these frequencies, we don't hear all of them equally.
White or brown noise appears to help the brain harness the neurons, focus attention and quiet noisy thoughts. It's unclear whether these types of sounds could also benefit people who don't have ADHD.
#1 White Noise
At the top list for any sleep sound is white noise. Far from a catchy tune, white noise is just a tone, offering a sleep sound that can help your brain relax, your eyes grow heavy, and your body drifts off to deep-sleep dreamland.
