Have you considered learning sign language?
I don't mean that it's the only solution, but it can be interesting, fun and useful. I have no hearing problems, but I would still like to learn it (I would find it fascinating to be able to talk without sound, like in a noisy place, or across a window, etc).
Once again, it's perhaps not THE solution to your social isolation, but it could be a neat thing for you to do, and you are sure to meet new people if you attend classes,...
