@steve Thanks for this good describtion!
I have a moderate low- and mid-frequency hearing loss on both sides and therefore have very similar problems to yours. Sometimes people even don't believe me, when I tell them, what I can hear and what situations are difficult or even a No-Go, just because they can't see it and I can follow conversations well in a quiet environment - and if the people I'm talking to are no more than 1-2m away from me.
I was diagnosed in the pandemic, but I don't know if there is a direct connection, probably it's more genetic in my case (because both-sided and does not affect high-frequencies).
I was teaching, too, but I had to stop doing that because of my hearing loss. I'm currently reorienting myself towards social work.
