Just like a concave mirror concentrates light, it can also concentrate sound waves. Ray diagrams like the following look as if all waves converge to a single point of INFINITE power density which of course is not true, probably because of the wave nature of light or sound. What is the correct power density at the focus point, relative to the incoming sound power density?
Is there a way to use multiple concave mirrors to focus all the sound from a source into a single very sharp point, with enough power density to sculpt granite?
