Is "Dark noise" the equivalent of "Brown noise"?
Note: Generally "dark" (as opposed to "bright") means emphasis on the lower frequencies, which is a good description for brown noise, but they aren't formally the same. Formally, brown noise refers to a power distribution that drops ~6 dB per octave, and I have no idea how strictly apple's "dark noise" matches the technical specifications of that.
Only affects the background noise feature, doesn't affect any other sound, music or video. I have no idea what causes it.
I generally listen to white noise when I am trying to concentrate, but its Dave Clarke's techno/electo podcast, "White Noise"! https://www.youtube.com/watch?v=36FkrrpzFOA
I’m sure I could train my brain to ignore the random sounds around me, since I grew up in a not super noisy city.
It really does help me ignore the distracting sounds. It gives my easy something to focus on rather than distracting noises.
Dark noise isn't an accepted term, it's a marketing term for a tweaked version of brown noise
