My grandsons hearing is fine, at least it was a couple of years ago when they tested it.
The thing is that someone with undiagnosed hearing loss can have some of the same symptoms as autism-—unconversational, wanting to do solitary activities, frustration with inability to communicate your needs.
When you’re hard of hearing, social situations w/ more than 5-6 people are really, really draining. When I go to big parties, sometimes I stick myself in a corner and just read a magazine or a book because it’s really mentally taxing to listen to and keep track of multiple conversations. Hearing aids just amplify everything so have a limited usefullness as well.
