It turns out that dragging your nails across a chalkboard is NOT the most annoying sound in the world but it's in the top five. In fact, it's not even the most annoying sound you can make with a chalkboard.  

Scientists at Australia's University of Newcastle had people listen to sounds while getting an M.R.I., and saw which sounds produced the strongest reaction in people's brains.  Here are the five MOST annoying sounds in the world:

#1.)  Rubbing a knife against a glass bottle.

#2.)  Dragging a fork across glass

#3.)  Writing on a chalkboard with chalk.

#4.)  Rubbing a ruler against a glass bottle.

#5.)  Nails on a chalkboard.
