White noise is the classic mesmerizing noise used all over the world, mostly to help put someone to sleep. The noise is a constant static-like sound, which is known to push you into a daze. However, brown noise is a deeper and quieter noise that is now becoming almost just as popular as white noise.
Personally, deep brown noise makes me feel more comfortable and at ease than white noise does. It is a bit quieter, so i can see why most people would still prefer white noise especially in terms of sleeping. It makes me feel as if I am on the ocean late at night with dark and deep surroundings. White noise on the other hand makes me feel like I am on the beach during the middle of the day, which is just not as soothing overall for me.
Other that white and brown, there is also a pink noise. I believe pink noise to be a middle ground between white and brown noise. Pink is brassy like brown, but I do think that brown is the brassiest. I feel at ease with pink, but truly do prefer brown especially in terms of sleeping.
Here is a link to one of my favorite deep brown noises, it brings such a great sense on comfort to me.
