I have both of these symptoms. I always keep my TV remote in my hand so I can mute the commercials. They're always too loud. I get very irritated when I can't mute them. I can't stand high pitched noises either.
I get migraines from artificial fragrances and am extremely sensitive to any other smells as well. Even things that other people don't notice.
A friend of mine has an autistic child who has sensory processing disorder. She's always posting Info on Facebook about it. I'm not autistic but I believe my symptoms are related to SPD.
