WHAT?!??!!?
:)
Yes, they do.
I’m pretty much deaf in my right ear and you can do pretty well with one good one.
Still feel bad for the guys.
I was given lip reading lessons all throughout school starting in second grade. I've adjusted well, I don't hear as well as other people but you wouldn't really notice it because I've adjusted to it so well. I'm even quite a good musician. I'm a guitarist and pro bassist and I also sing well.
So yes, you CAN do very well with a hearing handicap if you don't let it get the best of you. You can overcome it.
