The best color noise for sleep (2025)

As a certificate Five -year -old sleeping science and tester, I am not a stranger to the soothing noises of the health arsenal of many people. For some, the sound soundtrack may be white. For others, this can be a different color – sometimes they are played on their phone, but often they leave a goodwill audio device. If your audio device or program offers different types of color sounds, how can you know what they mean, or which one is best for your brain?

How the noise is “color code”

Let’s turn on your Shelldon Cooper for a minute and determine why some special sounds are classified into colors. Voice travel in waves, like light. The frequency of an acoustic wave, measured at Hz (Hz), is the number of waves that convey a particular point in a second. Long sounds have high frequency (and short wavelengths), low -speed sounds with low frequency (and longer wavelengths). The human ear can distinguish sounds from 20 Hz at the bottom to 20,000 Hz at the upper end.

About colors? In part of the light spectrum we can see, different frequencies are understood by our eyes as different colors. By comparison, the “color” of a sound is a short way to describe the quality of that sound, which is determined by a specific combination of sound wave frequencies. (People with a rare disease called cinstage literally see certain colors, but this is a different subject.)

Most people are familiar with the “white noise” cars – in fact they are quite synonymous with audio cars. Just as white light is made up of all visible colors, white noise includes all audible sound frequencies simultaneously. The result is similar to the noise of the environment that is the audio background for your daily life. Some likens it to static TV or running fan – which seems to be the main mechanism of one of my favorite audio machines (see the picture below).

Returning to 20,000 kHz that humans can hear – white noise is all, all at once. If you live in a taller environment like a city or a roommate, white noise may be a useful tool for you. This does not appear to make the horns look like the headphones make the noise, but can “mask” voices. In essence, the combined frequencies borne loud noises so that your brain does not choose as much on them.

White Smart Audio Sound

Pink sound

Some believe that pink noise is the best sound for sleep. Like white noise, it contains all the frequencies we can hear, but instead of putting all the frequencies at the same height, it emphasizes the lower frequencies, as the white noise does. This leads to what some describe as “flat noise” that is much softer. It is often likened to rainfall or ocean waves. Some studies have shown that it increases deeper sleep and also relaxes brain activity, so you sleep faster.

Noise

The brown noise “everything about that bass.” Like pink noise, the OOMPH enhances lower frequencies, so they are more prominent – but even more. The result is deep and deep. If you like to fall asleep and listen to thunderstorms or you love those long distances BoomLikewise, brown noise may be your color.

Green sound

If you feel “green” with a green noise, you are not far from what you experience outside the home. Instead of putting all frequencies at once, such as white and pink noise, green noise emphasizes 500 Hz, which is the middle frequency. If you have the spirit to chase the waterfalls in your dreams (I hope you get a reference), the green noise is more like the sound of water and wind. So listen to waterfalls, ocean waves and wind through trees to your heart content.

Noise

All types of noise remain in the low -frequency range to the middle. But the blue noise really reinforces dialing and prioritizes high frequencies. Explicitly, depending on sleep, it may be more likely to be hit or losing. Some may find the sound (some describing as steam whistles) to work or stay alert.

Purple

Purple noise raises high frequencies (triple) even more than blue noise. Basically the opposite is brown. Everyone is different, but I can’t imagine I was sleeping in this way.

Pump the beat

Using sound to promote sleep and all ways that can affect your brain and health is still explored. However, you can test with these different types of noise and see which one you answer (or better to say, make the most).
