A friend of mine has both parents completely deaf & I also worked for a man who had 6 deaf children (who were all adults).

Their houses were just set up to deal with it. The phone had a flashing light & a computer attached so the talking was adjusted to words on a screen & they could type the answers. If you need to make a phone call (I received many when I worked for this family), the person on the other end would hear an automated voice saying "you have a phone call from xxx please speak slowly & clearly as your words are being translated for a hearing impaired person." It's a bit strange talking to a computer voice, but it works.

Door bells can be set up with lights attached so you see the light flashing instead of hearing the sound.

I'm not sure what happens with smoke detectors, maybe contact your local fire station & see if they have something that would work. I'm sure they wouldn't mind & would be happy to help someone that is trying to protect their house & family.

I can imagine it's very scary for you to lose your hearing, I hope it slows down for you.
