Our door bell no longer works. The sound was obnoxious to begin with so we haven't hired an electrician to fix it yet. I'm thinking a door knocker would be more fun. Usually I see them on the door, but our bell was on a wall. People keep telling me the bell doesn't work. So maybe we should install the knocker over the bell? I don't even know if that would emit sound in the house.

What do you have?
