Most people have heard of white noise, the “hissy shhh” sound that comes out of a badly-tuned radio or TV. But what about brown noise? Well, brown noise is similar, but it’s lower, so it sounds a little like a low roar sound.
Like white noise (and pink noise), brown noise can help you relax, sleep or even improve your focus when concentrating on study or work. But before you go out and buy a brown noise machine, try listening to it via YouTube or downloading an app on your phone. If it works well for you, get the best results by playing it continuously all night on a loop without breaks with a brown noise generator/sound machine.
