I get it all the time now, older and softer cicada sound, indoors, outdoors, no electronics, 24/7.
Have learnt to block it out from conscious mind.
When it’s loudest, that’s usually when I’m fully wired up and can make very quick connections that others don’t see, quicker than normal. More “psychic”.
AB-.
Not tinnitus.
This thehum.info looks interesting, so thanks to anon for posting.
Been wondering for over a year what it is- energy obviously, but…
Anyway thanks for the info, over and out on this topic from me, (I plan).
