Very interesting. My homunculus is very ears forward. A lot of my work and fun revolves around my relationship with sound. I did a hearing test last year. It was fine. I have not directly noticed any issues with my hearing, but I recognize that the types of things I might be experiencing might not be so much perceived as hearing but more as orientation, balance, or even be queues to memory that could be altered.

If you had the information available, I'd be very interested to know the names of the diagnostic tests you took. Analysis of how I'm hearing is something I'm uniquely able to analyze over time and compare to medically conducted tests. While I think I know how the second test might have worked, I don't know what I'd call such a test to look for it.

I think analysis of hearing on newly infected to post care of people with COVID and Long COVID could provide useful hints that most other methods might not be able to detect.
