me too. I was dyslexic as a child and I am very sensitive to sound (can hear the grass grow type). It did make me a good sound engineer. I can sound-proof just about anything. But I can't hear a word anyone says in a bar.You know, I just had a hearing test (I'm 61), and it was the best they had ever measured in their office. I like to joke I didn't listen to that much rock and roll when younger - but maybe inner-ear stuff can actually mean hearing that's "too" good. I do have a problem filtering out noise - so perhaps it's all related.
The pianist, Alfred Brendel, was said to have suffered from this greatly. He was well-known for canceling performances because he couldn't sleep in the hotel room because of noise.
