My father was deaf and he said you must always wear your aids and regularly be prepared to upgrade them.
I'm sure you are already doing this but if not it might be worth checking with your audiologist.
I know he said that it's unfortunate that people don't really understand and make allowances for deafness.
With my mother-in-law we try to go to places ahead of or after the crowd - early or late lunches, early dinners etc and avoid echoing spaces.
Might it be a good idea to go to groups where people speak one at a time - such as a book group?
Or do you play (say) bridge?
I would look at what activity based groups might be suitable.
If you are meeting friends somewhere new I'd phone in advance and ask if they have a quirter area. I'd tell them that someone in your group is hard of hearing. They can't always help but usually they can.
We do this every time we are out with my mother-in-law.
Thinking of you.
Deafness is a bit of a hidden disability it seems to me.
Hard of hearing is a hidden disability and regarded as such within the NHS. The digital aids are a godsend with a smart phone, learn how to use it and also 'how to use your phone as a microphone. You can zoom in and out on your phone as has been described above. Patience as out all takes time to learn, but you will get there. A Roger Pen is also good, see your provider and specialist and to what is available, The NHS is near enough as good as private now. I have had aids for 40 years myself.
