It’s always nice to find out that other people share your fondness for something odd and you had no idea of a larger community.
I came across brown noise in my “white noise” app. Like many others have found, actual white noise is far too harsh to be relaxing but when I came across brown (even over other tweaked versions like pink and blue noise) it was a revelation. Immeditately soothing and now my brain is trained to basically shut-off when I turn on the brown noise. For someone who has always struggled falling asleep it’s a life changer.
