I have started listening to random American city council meetings lately for white noise. Since they're all bureaucratic-flavored boredom anyway.
LiveATC streams. If you are not listening it's a constant stream of radio-garbled jargon. Just pick a busy airport.
This and the other trek ones are great. Especially the TNG night shift bridge.
I have chronic tinnitus. My ears generate white noise for me without asking.
Either SoX running in Termux on my phone with:
play -n synth brownnoise synth pinknoise mix synth 0 0 0 10 10 40 trapezium amod 0.1 30
(originally yoinked from I can't remember who, in the early days of Mastodon)
or more recently, a 10-hour loop of the Sardukar chant from Dune. It's right about the right frequency to block a lot of the noise around here and it isn't anything intelligible for my brain to keep me awake thinking about.
If I just want some noise-blocking sound while I'm trying to code or something then myNoise has a vast array of sound generators. It was well worth kicking them $5 a while back.
He’s still a superstar and the leader in his field, but it’s mostly background noise for the uncut versions I’m listening to for the fourth time
