I also have the problem with certain sounds. I thought I was just insane until I read about Misophonia.
I can never be around people who are eating, and barking dogs are the bane of my existence. With some people, it's literally every sound they make. Those people tend to be disgusting pigs though...

Headphones and isolation are the only things I have ever found that help. It did make me feel better when I heard that this 'neurological condition' has a name, and I am not the only one who is like this.
