How does a hearing impaired introvert make friends?

My hearing impairment is sensorineural. With my hearing aids, I can hear speech, but have difficulty understanding as there is little clarity, especially in environments with background noise. When I try to explain to hearing people (very politely) how they should talk to me, they either quickly forget, stop trying to talk to me, or tell me it’s ‘not important’. This leaves me quite isolated. There are no ‘deaf clubs’ nearby and those that are available cater for the Deaf community where everyone speaks in sign language, which I don’t understand. The deaf have there own culture and language. I find, as a hearing impaired person, I’m not part of the hearing world, but don’t fit into the deaf world either. Any suggestions would be welcome. Thank you.
