Those are three much-hated sounds for me, too!
Recently, I got stuck on a very long tech-support call with a customer who had a hyperactive kid intermittently screaming in the background through the whole call... HORRIBLE, SUDDEN, HIGH-PITCHED SQUEALS!! ! She just laughed it off - and of course, I couldn't say anything about it - but I was honestly ready to explode by the end of the call. It took me hours to calm down.
Also, one of my neighbours happens to have a brain-dead dog that will bark incessantly for HOURS on end. (Thank God for foam earplugs...)
My intolerance for those sounds is definitely much lower than anyone else I know, and nobody ever seems to "get" why they stress me out so much... Thankfully it's not stopped me from working or going out when necessary, but they really get my blood boiling - especially if there's no way of "escaping" them.
(Other sounds that I can't stand are stomping feet, loud voices, slamming doors, motorcycles, and cars with "sewer-pipe" exhausts.)
