8. Lip reading definitely works and is the idea solution for .....
high frequency hearing loss.
Locally, there are classes in lip reading, given by a very generous and talented person. Each week, she makes up new and interesting word games where she "speaks" silently but with the perfect lip movements. Her classes are packed with people, mostly oldsters, who can absolutely understand what she is saying.
To learn lip reading, you need someone to read you a list of words all starting with a particular consonant letter, for example "M" words, and learn and remember their lip movements. For the vowel sounds .... those are not high frequency and you can probably hear those.
I barely get by with a hearing aid, and so far, have not taken the time to learn lip reading. But lip reading is definitely effective for high frequency loss.
