Adult with ADD here. I like to use grey noise while studying and find it has even less of the annoying high pitch of white noise (vs brown). I also like the sound of a stream or creek, which is close to brown noise. Grey sounds like a very large waterfall to me. These kind of noise also really help for blocking distracting background noises, especially when used with noise canceling headphones. I find noise canceling doesn’t work by itself because it lowers the noise floor so much you can hear everything still.
