Purple noise, also called violet noise, is a type of colored noise with significantly boosted high frequencies, sounding like a sharp hiss, sizzle, or steam/faucet noise, which is the opposite of brown noise and more intense than blue noise, often used for tinnitus masking, deep focus, and blocking out other sounds due to its high-pitched, sparkling quality that draws attention away from ringing.
The opposite of brown noise, violet noise removes many low-end frequencies. It sounds like an open water faucet, a sprinkler, or a trickling stream, and is great for tuning out other sounds.
What Color Noise Is Best for Sleep?
Violet Noise features high frequencies with less low frequencies. To some, violet noise can be heard as a sizzle or hiss. It can be popular for tinnitus masking, ear ringing or fatigue. Many people find this noise incredibly soothing and relaxing especially when mixed with a beautiful sound track.
If you are ever to determine how to deal with noise in your space though, you need to understand the four types of noise; continuous, intermittent, impulsive, and low-frequency.
The different colors of noise include white noise, pink noise, brown noise, blue noise, gray noise, and violet noise. Each color has unique properties and frequencies. Which makes them suitable for various applications such as sleep improvement, relaxation, focus, and even audio engineering.
The study evaluated the Tinnitus Handicap Inventory (THI) of patients' usage and tested the indicators with paired sample T-tests. The results indicate that “pink noise” is effective in the treatment of tinnitus, and the differences in the scores are statistically significant before and after treatment (P<0.05).
The healthiest noise for sleep depends on preference, but pink noise (steady rain, waves) and brown noise (deep rumble, heavy rain) are often cited as healthiest for deep, stable sleep by calming the nervous system, while white noise (hiss) is great for masking disruptions, with all working best at low volumes to mask jarring sounds, creating a more consistent soundscape for better rest.
Many people find that white noise, pink noise, or nature sounds—like rain or waves—are particularly helpful for easing anxiety. It's worth trying different options and seeing what feels right for you. Calm Noise is a blend of different noise types designed to offer a balanced and calming sound.
Likewise, The Sleep Foundation claims that blue, green, and white are three of the best colors for restful sleep, and red, bright orange, bright yellow, and black are the worst.
Annoying Sounds That Can Ruin Sleep at Night
To 100% fall asleep, combine a consistent schedule, a cool, dark room, and a wind-down routine (no screens, relaxing activities like deep breathing or hot baths) to calm your mind and body, using techniques like the 4-7-8 breath or military method if you're still awake, and get up to do something boring if you can't sleep after 15 minutes to break the anxiety cycle.
Pink noise sounds like a waterfall or rain falling steadily and is considered more soothing than other colours of noise.
White noise can improve sleep quality, suppress background noise, and increase relaxation. Pink noise promotes relaxation, enhances memory, and stimulates growth hormone production. Brown noise helps increase concentration, improve creativity, and reduce stress. Finally, green noise is perfect for relaxation.
As a once-royal color, purple symbolizes wisdom, power, spirituality, luxury, wealth and nobility. Since it is between red and blue, purple is known for the combination of red's power and blue's stability. The color purple also symbolizes independence and dignity.
