My oldest wears hearing aids, and we're always looking for assistive devices to help her out. This latest one my wife found is kind of intriguing, and I think it could be handy in a loud work environment as well
It's an improvement over the basic phone flasher because it can flash different colors or sounds depending on the phone or doorbell that triggers it, and they are wireless with a 600 foot range. (Now your family won't have to scream at you that it is dinner time while you have your hearing protection on....)
I haven't seen it in person yet, but I think it may be on my daughter's Christmas list this year
