Any high pitched shrill beep, like those beepers for the lazy-people carts at Wal-Mart. Oh, and the beeps of the cash register at a specific register that has that high pitch bEEEEEp! Drives me bat shit mad when I get stuck on that register all damn night.
Another is the ting-ping-ping-clink-clink-clink-clink-ting-ping of my ceiling fan when its on. I need it on to keep the room cool, but the constant noise drives me mad.
