I understand this is an actual medical condition. Other PB's have written about it in other posts. I'm blanking on the name, though. Sorry.

For me the worst is the bing bing on cars. After five or six bings I have to get out of the car and walk away to where I can't hear it anymore.

The sound of basketballs on concrete activates my rage trigger.

Screaming children in the store. If I pass them I say duct tape!High pitched, repetative sounds are the worst, but I've read that a lot of people can't stand to hear other people eating.
