You might install a wireless transmitter and additional remote chime(s). You also might see if a different chime or tone is in an audible region where she has less hearing loss. I imagine that the existing unit gets all the curren it needs and you wouldn't increase the voltage. They also might have units to wear like a pager on vibrate. Joe
There are certainly louder noise makers. The piezo from a smoke detector springs to mind. There are also bells like you see on alarm systems. Now days there are also solid state sound drivers that can make any kind of sound from police sirens to Bach (Tocata and Fugue in D minor springs to mind). I guess it all depends on what sound she wants.
Increasing the amperage will not nake the bell louder! The actual current through the ringer coil(s) is determined by the voltage and the resistance/impedance of the coil, so unless the current transformer is grossly undersized a larger transformer won't help. Incresing the voltage will do though. Only works with classic bells of course, not with electronic chimes. Outdoor bells for factories spring to my mind, they're incredibly loud so they can be heard over the noise of a factory yard or school yard during recess.
Yes, a multi-tap transformer connected at a higher voltage will make the chime louder.
Hows that? Does it hit the bell any harder? I didn't notice the last time I did that, (by accident) but it didn't last very long. (I 24'ed a 16...)
Anyway I recently had an older lady customer complain about her chime over the phone to me - that "it doesn't work" so I showed up, and without thinking - I rang it, and I could hear it out front. There I was standing with a possible replacement in hand.... (Nutone Ding Dong) NOBODY ANSWERED - rang again... Remembering my earlier phone conversations when she told me the doorbell didnt work , she told me to call... Wanting the service call closed, I called, and I could hear her old Ma'Bell phone out front. (The type with a BELL inside...)
The lady comes out, and we talked about her chime, and I said it worked... She didn't hear it... Walked inside and she had the exact same one that I had in my hand. I told her that the one I had wasn't goning to be any louder than the one she already had, then we started talking about why she can hear the phone... I had an idea, and we went for it... I hollowed out the old chime and put a 4" bell in it. When I was done it sounded like the end of lunch in elementary school, and she said it was just loud enough....

I'd suggest that you get away from the standard door bell idea and only use the door bell system to trigger a relay. Once you have a separate system you can get 120vac bells or what ever. The standard door systems are very limited. With a relay in the system you can also place multiple doorbell around the house.
