Yea. I feel like i might have this too.

If i'm watching tv i can hear it fine. If i'm watching tv and people are in the room talking, i have to put subtitles on.

If i'm talking to someone i'm fine. If i'm talking to someone and the tv's on or other people are talking in the background i can't hear them.

I just assumed i was going deaf from listening to music too loudly.
