I consider myself introverted because being in a large crowd is very exhausting for me. But recently I found that the main problem I have with lots of people is that the sound level gets so high that I have problems following individual conversations. It takes me a lot of concentration to understand the person next to me. That's why I mostly avoid crowded or loud places, since I wouldn't understand a thing anyway. I generally hear well, but seem find loud sound painful earlier than other people. Because of this, I wonder if hearing problems could be a cause of introversion.
