I didn't realise that people lost low frequencies as well as high!
I can still hear way low, which I like, but my high frequencies are gone.
More worryingly, I am pretty much deaf at certain upper midrange frequencies. They don't coincide with the notes on a well-tuned piano - I can hear all of them - but if a loud noise is going off at one of the precise troublesome frequencies I wonder why people are running around blocking their ears! (It happened at work once when I accidentally blasted them with a tone that I couldn't hear. I could hear the frequencies immediately either side of that particular one.)
As for tinnitus... It is there in the background but I don't normally notice it. I haven't worked out why, but sometimes it seems to become more noticeable and annoying.
