I have a weird but similar problem; I think I’d call it “aural focus dysfunction.†So far as I know, my hearing is okay - not great, probably time to be tested, but good enough to follow a conversation.
My problem arises when there are three or more voices overriding each other. It’s as though my brain can’t identify which words go with which sentences, or which speaker.
When I worked, I had a shared office and a lot of meetings,either in the shared officer in meeting rooms. I absolutely could not follow. This, along with some executive-function issues, contributed greatly to my early retirement.
