This makes total sense to me, but it didn’t know it was called “brown noise.”
Many years ago I found a “sounds of the tropical rain forest” CD in a bargain bin and bought it, for the hell of it: I found it totally soothing. On a hot dry day in northern CA, where I live, I can put it on, and when I go outside later I’m sorta startled that it’s so…non-rainy that day. It lulls me into being tricked out the actual weather.
I know I must be on some sorta “spectrum,” but hey, whattyagonnadoaboudit?
