first instant of a lot of people, that 'I don't need a hearing aid!'. My dad was this way.
Of course wearing the hearing aids is going to be a learning experience for you and others around you. I've worn hearing aids (HAs) for roughly 60 years, so it does take some getting used to.
Some tips...Yes, the world is loud. But use the hearing aids to filter the sound out, that is, simply turn them off. Then you got earplugs, and the noise is gone.
Get into a routine where you automatically charge the HAs, like at night when you take the aids off to sleep (I take mine off at night too, use the closed caption on my TV to 'watch/listen' to my shows.
Windy conditions usually make wearing the HAs a challenge, as the wind is blowing into the microphone of the HAs, drowning all sounds out. You're better off just turning the HAs off...wait until you're out of the wind.
Maybe have a spare (HA), just in case you are going somewhere, and need the HA to hear (and the original HA(s) aren't charged up yet (or still charging), if you had a spare, then this will help ease your concern. I am assuming that you don't have batteries, and that you plug in the HAs to recharge?
You're going to really like not missing so much around you though...this is a wonderful moment for you. Again, Congrats. Oh, by the way, you might check into any insurance you may have, on your HAs. Sometimes the place you buy them from will offer insurance on the HAs. Believe me, sometimes you'll misplace the HAs, forget where you put them. Whatever you do, don't put the HAs in a readily available spot so your pets (if any) will grab the HAs (they like the earwax).
Best wishes to you!
