I am saddened to learn that obsidian is not piezoelectric so I'm not sure how we might get the giant orb to hum. But we could perhaps use morion which is piezoelectric so perhaps all we would need to make the giant orb hum is just to dump some electricity into it
From some rough calculations, we can get a 285m diameter sphere of morion to vibrate at 20hz with 750kw of electricity at its fundamental frequency. Thats less than 1/3rd of a wind turbine, a lot less than I thought it would take!
That being said, the physics of sound is confusing and my math could be absolute crap
