K, Kelly, this is verbatim my reply on Wildflower's thread on Sensory Integration: Lack of concentration due to background noises isn't the same as sensitivity to noises. I thought they were one-and-the-same, and they may be intertwined, however, when my difficult child started experiencing extreme sensitivity, and I explained it initially to his psychologist & psychiatrist, they both told me the same thing. I was assuming a connection to me & my mother's inabilities to filter background noise. I cannot concentrate on a phone call if a convo is happening close by, I cannot hear convo in my car if traffic is particularly busy, I can lose my thread of concentration...if, uh. Sorry, the phone rang. They both told me that what I am experiencing is an actual disorder of its own, Auditory Dysfunction. It was, like most disorders these days, largely unrecognized until recently. (How did doctors & scientists used to make $$? Seems they figured out 90% of the world's problems just in the last 20 years!) It was considered a type of hearing loss. Anyway, I may be a bit off on the name; there isn't much you can do about it, it's basically an inability to properly filter unnecessary noises. So I haven't done much studying or follow-up. It's more like, interesting personal trivia for now.
