I don't know if all hearing aids today can do what mine do, but a feature of mine makes them especially valuable. My Phonak hearing aids, issued to me by the V.A., included a small gadget that attaches to my TV and sends the audio signal directly to my hearing aids. It uses the optical audio output from the TV, so I can even turn off the speakers totally and still get the full sound to my hearing aids. I do this often when my wife wants to read or sew in the living room where I am watching a TV show that she is not interested in. Even with my hearing aids I have trouble discerning speech unless the person talking to me is facing me directly, and in places like restaurants, with lots of noise from everywhere, I think the hearing aids might actually make things worse. But if I face the person speaking I do OK, and as I said above, watching TV with that feature is perfectly comfortable and I don't seem to miss any of the dialogue.
FWIW, while my hearing loss started when I was on active duty, and may be related to when I was in Vietnam and my unit was adjacent to a 8 inch howitzer battery, I think it was/is the decades of motorcycle riding without using any hearing protection that really did me in. Riding a motorcycle makes the wind noise inescapable, and the only real solution is to wear ear plugs of one type or another. I do so now, at least most of the time, but all those years riding have taken their toll. I strongly advise anyone reading this who has decent hearing, and is a motorcyclist, to not wait until irreversible hearing loss has already occurred before starting to use earplugs. The best ones that I have found are from a company named Earpeace (much less espensive than custom earplugs, and more effective as well).
