You may have heard of white noise. But did you know that there is also brown and pink noise? Even these lesser-known colorful sounds can also help you calm down, focus better, or even improve your sleep quality.

White noise

It is the most popular type of colored noise. It contains all the frequencies found in the spectrum of sounds that you can hear, in equal parts. It is often called "broadband noise". White noise uses a combination of audio frequencies to create static sound. It can be intensive, such as a fan, air conditioner, or vacuum cleaner.

Studies have also shown that white noise can help:

• improve sleep
• reduce crying in children,
• improve work and study performance,
• relieve ADHD symptoms.

Pink noise

Pink noise filters out distractions like people talking or passing cars, so it doesn't disturb your sleep or study, but it's much softer than white noise.

Like white noise, it's a constant hum in the background. However, it uses deeper sounds and lower sound waves, so it has a more soothing effect. Basically, these are lower tones than white noise tones.

You can think of pink noise as rain, the sound of wind or waves on the beach.

Pink noise can help:

• improve concentration,
• improve sleep
• induce a feeling of relaxation,
• filter out disturbing sounds from the surroundings.

Brown noise

Brown noise, often called red noise, produces a rumbling sound that is deeper, with bass-like tones. It is similar to the sound of long heavy rain.

Brown noise can help:

• reduce the symptoms of ringing in the ears,
• improve thinking
• speed up falling asleep.

Different colors of noise

In addition to white, pink and brown noise, we also know:

• Blue noise: its power increases with increasing frequency. Blue noise sounds a bit more penetrating than pink and white noise. Imagine the hissing sound you hear when the spray starts.
• Purple noise is the opposite of brown noise. The volume increases as the frequency increases and it gains energy faster than blue noise. It is one of the higher-colored noises. It is often used to treat tinnitus, a condition that causes a loud ringing in one or both ears.

Gray noise: produces noise at higher and lower frequencies, but not at mid-range frequencies. It is similar to white noise but more balanced.
