Hearing Loss - How Your Brain Compensates For Hearing Loss

Older people that get hearing loss will automatically compensate for it by reading lips. Whether they realize that they do it or not they do seem to learn to read lips.

Even as someone who does not suffer from hearing loss (at least not yet), I find that when talking with someone who has a foreign accent and is hard to understand, that by keeping face to face contact with them I can understand them better.

So it seems natural that someone who suffers from hearing loss will automatically study your lips as you speak to them. So if you see someone doing this at a rock concert, they have either blown their ears out already or they are really trying to listen to you.
