Information regarding Autism

It's a spectrum. Some of us (such as me) have issues with things such as noise. Please don't do what some bright spark decided to do - I attended an event for people and parents of children with Autism. Suddenly, out of nowhere, came this really loud music. I could not rush to find the exits fast enough! Which is difficult when you're in a strange place and visually impaired... Really would have been nice to have had a warning that at some point, there would be some really loud horrible noise.

Hiya @CAIY

I'm not sure there's much I can add to the excellent advice already given, except that I would 100% recommend that you ask around locally and try to speak to parents of autistic kids ahead of the event, to get some idea of what they'd like the event to cover.

If you're likely to be doing this kind of thing on a regular basis then it would be well worth getting an autistic adult onside as well to help out, as they would be able to tell you straight off whether certain environments and/or activities might be problematic. 

The difficulty you might have is that as has already been said, ASD is a spectrum condition and everyone is affected differently. I can cope with surprisingly loud environments so long as I'm concentrating on something, for example, but in a quiet room I would be massively disturbed by the sound I can hear from fluorescent lighting. Others would be the opposite way around, or might not be able to cope with a lot people around them, that sort of thing. 

I would definitely try to get some knowledgeable help 'on the ground', as it were. Good luck!
