Hi, Geoff, and welcome to the forum!
Hmmm...I'm going to make a general comment about an emerging theme of this thread: I have to admit that I have no problem with the term "hearing impaired". I've operated in the hearing world for my entire life. I didn't have a significant hearing loss (moderate in one ear, mild in the other) until about 3 years ago. (Prior to that, I had a slight hearing loss in one ear only.) I still operate in the hearing world; it's just that now I wearing hearing aids. My hearing now IS impaired as compared to my previously normal hearing, so I have no problem with using the term "hearing impaired".
That said, I don't necessarily think I need to label myself in any particular way. As my deaf audiologist said to me recently, "Do you tell people that you're 'visually impaired' because you wear glasses?" No, I don't. Her point was that I don't necessarily need to label my hearing issue. That doesn't mean that I don't label myself as hearing impaired, HOH, etc. at times, but for the most part, hearing aids work well enough for me that most people wouldn't know I have a hearing loss, so I don't tend to label myself as either "hearing impaired" or "HOH". I have terrible eyesight, and I wear glasses more often than I wear contact lenses, but I don't go around telling people that I'm visually impaired.
I realize that the term "hearing impaired" can be offensive to some and I can certainly respect that. Being d/Deaf does not make a person any more "impaired" than being young, being stupid, or being tired does. I wonder if it's just a matter of perspective?
