I had tubes in my ears when I was a kid. I guess my ears are in pretty bad shape, but I don't have much hearing loss or anything. My high-frequency isn't great, but my hearing is still within the average.
edit: And then there was this time in the 3rd grade, I think, when we were doing a fire drill. I don't know if you're familiar with exactly how these things work, but I guess in case of a fire you need to be deafened. They set off these alarms that are way too high and loud, and put them on the walls right next to where you're walking out of the building. So it's not that bad, until you walk a foot away from it. So after passing about 5 of these things and getting to the playground to wait around for 15 minutes, my ears are really starting to hurt. I was sort of a loser as a kid, so I wasn't exactly the center of attention or anything, so nobody pointed it out to me. But on the way walking back to class I noticed that my neck felt sort of warm, and looked over at my shoulder. I had these huge streams of blood running down my neck onto my shoulders. I don't know if that's related to the tubes or anything, but it really sucked, let me tell you. On top of that like a week before that the teacher wouldn't let me go to the bathroom because she was having problems getting the kids to come back. So after about an hour of not letting me go to the bathroom I crapped my pants.
