My 8 yr old brother has Asperger's and we've had the problem of the super sensitive hearing and behavior problems in the classroom. My mother and the teacher got together and have figured out that if Kevin wears earplugs during study time, he can concentrate a lot better and doesn't get so frustrated. Also, the kids in his class don't always sit all the time and it distracts him. They've made a sort of cubicle out of poster board (I think) to put around and it seems to be helping also. Best of luck to you.
