How can I produce infrasound using a bunch of piezo's? Answered
The industrial music pioneers Throbbing Gristle reportedly created something that was capable of producing sound at frequencies below the threshold of human hearing (infrasound) by wiring together a bunch of piezo's. I'd love to do this myself, but don't currently have the time and resources to experiment myself. Any chance that there's someone out there that has replicated this? Preferably someone willing to write up an instructable?
