I have started listening to random American city council meetings lately for white noise. Since they’re all bureaucratic-flavored boredom anyway.

You’re thinking of the brown NOTE, which has not been proven to actually exist.
It goes something like this:
White noise is a mixture of all frequencies audible to humans, which sounds quite high pitched. It’s excellent for focus, against tinnitus and just for it not to be too quiet. Helps a lot of people sleep too.
Pink noise is the same thing except tweaked to sound lower yet still “crisp”. It’s been shown to generally be even more effective for falling asleep than white noise.
Brown noise is the same deal yet deeper still. It’s been shown to be effective against anxiety and, at least in my own anecdotal experience, against anxiety-induced insomnia.
On top of all these benefits, a combination of all three is what headphones and earbuds use for active noise canceling, an effect you can also achieve to some degree yourself.
