A nouns that make me cough?

The sound of silverware clanging together make me freak out--and after a while makes me cough. What is this? A easily upset reaction - I dont see why individuals cant develop a hyper allergic reaction to sounds. You perceptibly have.
I dont hear that nouns usually - you work in catering?
That is pretty wierd. I chew over its just a response to getting worried by the sound. Maybe fright affects your lungs somehow.
