'No, you don't hear the sound' I assumed you would, since a selection of possible sounds is offered.
Yes my hearing aids do pick up the door bell, when they are close enough to it, but aids to not replicate normal hearing any more than a crutch replaces a missing leg. They just help a bit. I already have a door bell extender, which is why I am wondering if there is any way to get it's signal delivered to my hearing aids in the same sort of way that I can get TV audio boosted directly to my aids. Then I don't need extra bells in every room to be sure of hearing the door chime where ever I am.
