Sound waves are ALREADY energy. Really I'm not sure how this is meaningfully different from the already available aura shields and sword beams; besides being an overcomplicated method of achieving more or less the same result.

It also seems to change from "converting sound to energy" (again, redundant) to "controlling sound waves" half way through.
