They might shout or slow down their words to an exaggerated crawl- veeeerrry slooowly -thinking it helps. But with hearing loss, louder isn't always better, and neither is overly slow speech. Both can distort the shape of words on the lips, making lipreading harder instead of easier. Others forget the basics. They turn away, cover their mouths, or call out from another room, expecting us to catch every word. (Spoiler alert: We won't.)
When I did eventually get the test, I found out what was really happening to me. I learned that a build-up of earwax ( don't use Q-tips!) had immobilized one of my eardrums completely. After the somewhat uncomfortable removal, the test was rerun. I do have some hearing loss, which isn't unusual at 72, but the audiologist feels I'm years away from needing hearing aids.
