We took my son to the audiologist for his regular exam right before school started. We had bought a new hearing aid in March, but she couldn't program it to the highest level since he said it was "too loud." This time, she was able to do that, which increased it by 20%.
He says he's hearing well in the classroom, even though there are 34 kids in the class. He's alot more focused also (although he's now in the full-time gifted program so maybe he's not as bored). We have opted not to use the FM system this year since our school also has a Surround Sound or overhead mike system.
The audiologists and psychologists we have seen said that the auditory part of the brain keeps developing throughout puberty. They think his CAPD will get better! He's in his third year of piano lessons and will start the string orchestra this year.
I definitely think music lessons help CAPD alot. That is something to think about if you think your daughter has CAPD.
