sound activated sculpture

[r walz]

I hope someone might help. I am looking for a solution to part of a project:
I want to run a dozen mini sized fans via sound activation. I have little experience in this area. I see sound activation switches around, but unsure as to power source and wiring. Thanks.

You really need to elaborate more on your idea.
How should this fans be turned on, how does the sound activation affect their squence, are there specific fans to be active at specific times, what kind of sound should be produced to activate them, etc...
