I have explained to them about right brain and left brain activity. Left for language and math and right for creativity. I tell them they need to work in the right brain "zone". This is for HS students but once they get there the room is so quiet I sometimes have to play quiet music just so my shuffling papers and comments to students around the room as I cruise is not a distraction.
The latin teacher here lent me a Reiki CD and the kids actually like it! Need to get more of those. Some days are a little more energetic like Stevie Ray Vaughn or The Doors or even Bob Marley on Fridays, they sit , they work and sometimes nod with the music.
This may work for other grades too.

Some teachers start the class on automatic quiet. Students get printed instructions,.or the instructions are on the board, and they are asked to get busy - not noisy. Some teachers use a beginning ritual waiting for them to begin working on. The teacher instructions start after they are settled and working. This site has more information.
I know one art teacher that uses as red flashing strobe to alert the class that he needs them quiet.
