My Bampy was 75% deaf and he never raised his hand to tell people to stop or slow down, he just asked you to repeat things, there's never any need to raise a hand to tell someone to stop, as it is rudeness.
But i do agree with the OP, it is really awkward to watch people having a conversation where only one person is allowed to talk at a time, it's tedious.
