As an Aspie who visits their local community library often, I have found it is a good place to go for my sensory challenges. You have to plan what day you go though, or you might find you go there on a day where there is lots happening, so more noise. Like I did last Saturday for my book launch; there were 2 other events happening the same day, so there was more noise than normal. I usually my client on a Monday, and it is quieter then. People come and go and use computers, but it is quieter so I can hear what my client is telling me.
I also think the bigger library the less noise you will get. There will be more space to move around, so other people won't disturb you with noise. The lights aren't too bad either.
So, libraries are good places for Aspies to go, esp if you are a writer like me, and want to meet up with others to talk.
