For me, the results were that I have hearing ability on-par with a ~5 year old, and they only see adults like me every 18 months or so. I've got a printoff of the chart around here somewhere, but it's well outside the normal, especially for my activities.
On the flipside, I'm very ADHD, which I think hurts my loud-space conversational abilities some. I always figure my ears are trying to listen to all of it at once.
(Most lightbulbs and televisions drive me up a wall, because I can hear them all the time)
