Hi there.
I'm very sensitive to certain noises as well and other people seem to be very comfortable around those noises or at least tolerate them. I started psychotherapy, did some research, and ended up realizing my sensitivity (both emotionally and physically) is very high. I was born that way and this is not a disorder or a disease. However, every now and then anxiety and depression episodes have made me "hypersensitive" to things that wouldn't normally bother me and sometimes it might be hard to tell the difference.
I know this doesn't help much. Just wanted to let you know you're not alone.
