There is a name for extreme sensitivity to a particular noise. Most people who have this feel immense disgust at the sound of swallowing I think.

I looked it up for you; it's called misophonia.

A while ago there was a lot about it in the news because the AMC hospital in Amsterdam had developed a working treatment - the first/only in the world I think.

Misophonia is of course a disorder, and only a professional can diagnose you. According to the AMC 5-7% of the population has significant symptoms, but only 0.5% qualify for the disorder.
