My 85 yr old dad has selective hearing we think. If he has the tv remote he will turn the tv up so loud it vibrates cause he says he can’t hear it. He does have new hearing aids 8 months old. If you have the remote you can turn it at a comfortable volume he says he can hear it too. So why does he always turn it so loud?
This doesn’t pertain to watching tv but is a good reference for things to remember when dealing with anyone hard of hearing.
