One of the things that does affect me and my Asperger's is noise. Though, what noise it is has changed since I was a child and how it has changed.
When I was a child I hated going through the local subway under the train station. I think I feared the trains would fall down on me. I would stand one end, wait for a train to go over, then dash to the other end. I had to get used to it as it was the main way to get to the station if I had to go to hospital, and later to work. I did get used to it.
Another thing I hated when I was a child, and still do, is a balloon bursting. The bang makes me jump, so if you have a balloon and are with me, please don't burst that balloon. I won't like it, and I won't like you.
It seemed to be sudden noises I didn't like when I was a child, but now as an adult with Asperger's, noise comes to me as a sensory overload. I can't take too much loud noise in a small space eg loud voices in a small room. It makes my head go fuzzy, I can't take any more, and have to go into a quiet room, usually my bedroom upstairs. I think this must have been why when I went to a writers' party, after a while I would go to sit down away from the rest of the authors chatting. If I can get away from the noise, either to another area, another room or outside, then I will. It helps my head to calm down, and therefore, me to calm down, too, because I get upset if I have to leave a room when there are other people there.
So, that is how noise has affected me in the past, and affects me now. If you have Asperger's, how does noise affect you? The same? Let me know.
