My son, 9, responded similarly to loud noises and could detect the slightest sounds. I homeschool in part because the fire and tornado drills were terrifying to him. We finally saw an audiologist in OKC who sees kids--Dr. Larry Engelman. He tested my son and discovered that his hearing is off the charts good, but his ability to understand/filter what he hears is not good at all--60% in one ear and 0% in the other. This auditory processing problem made school really difficult--and explained why he either didn't respond to correction or responded inappropriately.
