No, thanks for the new term to make a note of. I do have a very mild form of misophonia but I believe that's a psychological glitch, not a neurological breakdown, so there are no noises or frequencies I physically can't handle (and particularly not in the sense of the EMR issues). I do very occasionally use earmuffs and seriously appreciate the quiet, but it's more "yay no sounds I need to decode" more than anything else.

Ambulance/police sirens are merely annoying, but due to some ear issues from when I was younger I learned about how my ear canal works and somewhere along the way I figured out how to use the muscles near my ears to apply pressure to make sharp noises 0.1% less sharp, so that deals with that.

If you want to keep in touch (via throwaway or non-throwaway email), I'm gmail@asmqb7 (decipher as per obvious). I'm curious about frequency-based health issues in general, because I wonder whether everything has similar root causes and the solution(s) for one are widely applicable to the others. FWIW I'm absolutely tragic with email (backlog months (!) long :P) but occasional back and forth of news etc may be interesting.

I'm fascinated that you have zero issues with RF (Bluetooth). How long can you use a tablet (= fanless thing with a screen in it)? Try seeing if your computer has Wi-Di (Wi-Fi Display) - it's a low-latency Wi-Fi-based display solution built into newer Intel chips. I don't have a new PC so I have no idea how it works, but if you have it it'd likely be the simplest way to solve the "can't watch YouTube over VNC/RDP" problem.
