Science is doing some amazing stuff with sound, but The Ancients knew the power of sound. Sound is a power full force, but destructive interference can cause a wave to collapse (think noise cancelling headphones) there is also Constructive interference which is what they are utilising through a medium. I could type for hours about it what the Ancients knew about sound. But I'm tired so maybe next time.
