You attribute that to tinnitis? I know for a while now, I've had the issue that as long as one person is speaking clearly, I can hear and understand them perfectly fine, but even if two people were speaking perfectly clearly directly to my face, I lose both of their speech. It's just so much sound. I can't concentrate enough to pick out either voice from the other. Multiple voices, I lose all of them. Odd. I never thought to blame the tinnitus.
not so much the tinnitus itself but hearing damage in general. the tinnitus is just a small part of it. when I'm in a quiet room reading late at night is when I hear the ringing the most. I have to sometimes put on some kind of background noise just to deaden the ringing.
