My son wears noise-cancelling headphones in his class room. Putting him in a tiled bathroom (the acoustics!) would be torture for him.

This year....he's taking trumpet....and guess what....his autism deficiency is GONE. I told my friend that they convinced the guy that it was a problem...and it became a problem. More to it....but basically, he didn't like parents yakking and yakking and would go play in another room.
