I'm on 50% disability from the USAF because of hearing loss related to explosions in Korea.
The VA gives me hearing aids that are pretty good, but I still read lips. Cover your mouth and I have a hard time understanding you, so yes, masks are a problem.
People have been great though. When I explain the issue, we both back off a few feet, they lift up the mask and repeat till I get it. I keep mine on, so one mask is better than none.
Your son and daughter-in-law have a much more profound hearing loss, for sure, so my solution might not work for them but I'm rooting for them.
