What is wrong with my ears?

Too much quiet irritates me.
I live in a very quiet area, and it drives me a little crazy. I put on music for a large part of the day (except when I’m studying), or have the TV on just so I can listen to something. It actually helps me concentrate better than when it’s completely quiet.
The reason that I ask this question is because I know that most people WANT peace and quiet ALL the time, and I think something is wrong with my hearing or something, because quiet irritates me. Especially when I try to fall asleep. It takes forever for me to fall asleep, even if I am very tired.
