Help others to help you.
If you suffer from hearing loss, you know that people are not always aware of your needs. So it is important that you tell them (politely!). Otherwise, how can they know? If you are in doubt, think of whoever is cooking and arranging everything; they want the meal to be a success. That means making sure that you and all the other guests enjoy the meal.
Tell your hosts what makes it easier for you. Maybe ask to sit where most guests are on your ‘good side’, or farthest from the kitchen or TV.
Ask your neighbour at the table to help you catch conversation or nudge you if someone is trying to get your attention.
If you find yourself struggling, tell people to face you when they speak to you.
If you find background noise distracting, politely let someone know you are having trouble hearing.
