In my 20s and 30s, I used to turn on the TV to cover up my tinnitus so I could fall asleep. The TV probably didn't help the quality of my sleep, so maybe that's why my tinnitus got progressively worse (especially in my right ear). Once I got a TV with a sleep timer, I would set it so the TV wouldn't be on all night.

My tinnitus is much worse now, but I don't have a TV in my room anymore, so I just play a podcast on my iPad. That tiny built-in speaker doesn't really cover up the tinnitus, but the voices lull me to sleep (which is probably what the TV was doing all along).
