I have started listening to random American city council meetings lately for white noise. Since they’re all bureaucratic-flavored boredom anyway.
Is that bit the reason people listen to white noise? Seems counter intuitive
Tinnitus is a constant whine. Other actual noise helps prevent having to constantly be thinking and feeling the whine because the “white noise” has your ear dealing with other things.
It isn’t the reason everyone listens to white noise but people with Tinnitus could help themselves go less crazy if they listen to white noise.
