I'm totally deaf (no response at +120db) on my right side.
I tell people that I have "no hearing at all, I'm totally deaf" on my right.
If they are interested in more details I explain how the machine that tests one's hearing is only able to go up to +120db - and even at that volume I can't hear anything at all (though I can feel the vibrations).
To put it in perspective for them I often explain that if a jet plane was (metaphorically) sitting on my shoulder, my right ear wouldn't be able to hear it at all - it'd just feel the rumble.
I was trying to explain to my sister the other night just how deaf I am. I told her my HA's are making your voice as loud as like a chain saw, or a helicopter, or a plane, because that's how loud I need it to hear it. Just picture that for a minute, a human voice coming out the back of a plane or a lawn mower. It had me giggling anyway
