Oh yeah... every little sound drives me crazy sometimes. Some mornings when I wake up, any sound, even soft sounds, feel like explosions in my ears. Some of my biggest dislikes:

My father-in-law whistling under his breath
My step-daughter singing the same line in a loop, like a broken record, out of tune (she has asperger's and ADD)
My daughters digging through their box of duplos (large legos)
Fingernails on a chalkboard
Chewing or slurping or lip smacking
Dogs barking
Lawn mowers and other power equipment
slamming car doors
Any music out of tune

Sometimes the stupidest little things can push me over the edge. Some of it is PTSD, some of it is just because I am highly sensitive.
