'Clapper' for a wall switch?

[Abe]

Has anyone know of a 'clapper' type device for a wall switch, or a wall switch that has 'clapper' functionality integrated?

I've searched, but not found anything using search terms such as 'sound activated switch.'

Instead of The Clapper, get a Chia Pet, connect wires to it, and plug it in
