@jetcitywoman said:My vote for most annoying sound is the fire alarm in my office.  I'm a quiet person and prefer somewhat quiet environments.  Plus since I work in an area that is mostly IT people, it's generally a quiet office.  So when they do the yearly fire drill (without advanced notice for some reason), Just a heads-up: you do *not* want to go to work in the computer chip manufacturing business. Monthly building evacuation drills tend to be the norm there, apparently. (I've only actually worked at a couple, but I've heard most of the rest do it, too.)
