You might want to consider these:
1)I don't think going to a bar is a good source for friendship. Bars are for hooking up not for common interests.
2) It's a bar, there's a lot of noise, even a person without hearing problems sometimes can't hear the other party when they talk. That problem becomes bigger for you.
3) How can you talk about common interest when you need to shout at each other?
4) I also don't think going to loud places would be good for your already damaged hearing.
You'd like to talk about stuff right? why not try to meet someone where people talk, instead of getting the wrong ideas about your motives?
