other human beings talking
nails down a blackboard it makes my skin crawl
Pots and pans clanking against each other.
I can get physically ill hearing the sound of metal scraping on concrete, or loud zippers.
Someone who can't sing a tune :(
i hate the sound of the clock hands XD<br />
crashed so many clocks till now :D
An electric can opener - I hate that sound, but I got to use it once in a while during cooking dinner for me and my wife.
