I have a relative who is hard of hearing, and I would like to create a circuit that would enable his doorbell button to light or maybe even flash a table lamp. I have measured the voltage at the doorbell and it reads 16V AC on my meter if that helps with the design. This is a great question for me since I'm also hard of hearing. I wear hearing aids, after a somewhat unpleasant series of operations on one of my ears. By the way, hearing aids are a great thing and have made my life better in many ways. If it's viable, please encourage your relative to try them. Mine even connect to my iPhone and beam phone calls, music, and podcasts directly into my brain!
