Decades ago I read about NASA's silent room, with the big wood spikes on the walls. All you can hear is your heartbeat and this high pitched whine. NASA figured out the high pitched whine was the nervous system (like, your brain).

I've got some mild tinnitus. I always wonder if it's my brain listening to itself. That little recursive loop is enough to distract me, even if it's not true.

I’d love to know more about this if you have any info to share.

I wish I could find a better source. My memory is of a wired article, on paper. This touches on the "hiss" from the nervous system - https://www.americanscientist.org/article/quietest-places-in...

Nada Yoga might give some information as well, it's not a new idea.

The sweet sound of you being plugged to a machine in a dream like state where a day takes 1ns.

but that would mean everyone should have tinnitus but not everyone does. I certainly never had it until midlife.

Maybe the cognitive ability to tune it out is what's failing. Old worn down brain issues.

Wait, what happens if the high pitched whine is always there when you’re in a somewhat quiet place? Is that still the nervous system?

[derekerdmann]

It’s self-oscillating

[ray_v]

what if the brain just runs an, "event loop" and the frequency is just the sample rate for responding to events?

That would require synchronous processing. In reality you have a trillion async threads.
