I sent a copy of my audiogram with the language comprehension scores in and was excused.
I was called 3 times before this, and sat on a jury once. I definitely consider it an important civic duty, but since I misunderstand a lot of words, and that wouldn’t be fair to either party.
If you have to show up, if they question you to sit on a jury, and if you misunderstand a lot of words, explain your dilemma to them.
It’s the best you can do.
