I thought I had hearing loss. I don't. I have Audio Processing Disorder. When I found out about APD and read its symptom list, I cried. It's me, all over. Between that and ADHD I now understand how my brain processes (or doesn't process) sound properly and why even a well intentioned (but clueless) audiologist told me I had "selective hearing".
I'm with him on this one. Commercials always end up being louder than the rest of the content, and are just.. annoying.
