We did the listening program under an OT. It did little for D but I have heard more and more parents who have gotten good results with it. I'm interested to see if anyone else here has tried it.
Sunset,
The program we did was under a trained professional. There was several sytles of music to pick from. The OT let D listen to a few minutes before he picked classical music...go figure! Anyway, the music is electronically modulated to simulate the brain. Its unproven and therefore usually not covered by insurance. We were warned that it might set D on edge and it did. Its really a more active therapy, not something smoothing. D couldn't read, watch TV, or play computer while listening. He could do things he wouldn't get lost in, like eat dinner, play a board game, whatever.
Its an idea to look into if your child has sensory issues going on.
