This makes the ambient sound more realistic and pleasant, less “static” and customisable to your needs. The great thing about Noisli is that you can also layer the sounds and add lots of other natural sounds on top. Therefore, the best option is to use an app such as Noisli, which lets you play brown, white or pink noise whenever you need it and no matter where you are. Also, they are often bulky and mainly designed to be put in one place and stay there, which makes it difficult to have them always with you when needed. There are many white noise machines out there, but the problem is that they are limited in the functionalities they offer. Some of the more commonly used noise colors are: The different colors of noiseĪlthough brown noise, pink noise and white noise are the most common color noises and the most associated with sleep, there are several other colors of noise. Listening to brown noise can help you fall asleep faster, improve your sleep quality and keep you in a deep sleep longer, which in return will make you feel more rested the next day. Therefore, any sudden noise will just blend in with the brown noise and won’t disturb you anymore. However, if you listen to some brown noise while sleeping it will create a consistent sound environment. Any sudden noise will wake you up and keep you awake, and your good night’s sleep is gone. Imagine you’re in a silent room at night trying to fall asleep. The reason why such sounds are used is because of their capability to mask distracting sounds that might otherwise disrupt your sleep or focus. We can find many familiar examples of noises, especially natural noises, to which brown noise is often compared, such as:īrown noise, pink noise, white noise and other types of sounds are known for their benefits, especially to help improve sleep, increase focus and concentration and even soothe babies. And while the lesser-known term “red noise” comes from the light analogy, as red noise is strong in longer wavelengths and similar to the red end of the visible spectrum, the more famous term “brown noise” comes from the brownian motion, a certain kind of random microscopic motion discovered by botanist Robert Brown, and the low-frequency sound this random motion produces. Other color names, such as pink noise, were then given to other noises with other spectral profiles.īrown noise is also called brownian noise or red noise. Consequently, the name white noise was given by analogy with white light, which contains all the wavelengths of the visible spectrum at equal intensity. White noise is the sound that combines all the different audible frequencies in equal intensity at the same time. The practice of naming some types of noises after colors started with white noise, the most well-known among the color sounds. You can read a comparison between white, pink and brown noise. Brown noise is even lower than pink noise. But unlike white noise, which combines the frequencies at equal intensity, brown noise is more intense at the lower-frequencies end of the spectrum and softer at the higher end. What is brown noise?īrown noise, as well as white noise and pink noise, is the sound you get when you combine all the different audible frequencies of sound at the same time. Let’s see what brown noise is, how it compares to other noise colors, and the potential benefits of brown noise for sleep. Brown, pink and white noise are also often used to block out external noises so to help be more focused and productive, and to cope with tinnitus or ADHD. Brown noise, along with white noise and pink noise, belongs to a group of sounds which are well known for being associated with benefits such as sleep improvement and relaxation.
