I’ve heard it called a number of things, linked to autism, hyperacusis, etc.
I have it. I hate the sound of people, some in particular, eating - not just how everyone hates nails down a blackboard kind of thing - but like a phobia, but instead of extreme fear I have extreme anger.
I will not entertain the idea of being in the same building as the person who triggers me the most - it’s had a huge impact on my life and has gotten increasingly worse.
There are a few other sounds too. But eating is the main one. Does anyone else have it?
