Im calling acoustic levitation crazy beacause it would require quite a calculative mind and vast knowledge in physics. Otherwise, it might work, though im not sure how the movement of air would actualy make it denser.

I was implying the use of the wave's sheer power to move onself, as if with air magic. Though of course, that is pretty harmfull to a human being.

Actually, moving air is less dense for a given speed. As warm air is moving faster on the molecular-level, and is in-turn, less-dense... ironicly, this would allow pyro-mancers to ride their own thermals with greater ease and less harm to themselves and others than acoustics and wind-bags.

As noted, self-immune. Not many sci-fi characters self-destruct upon reaching maturity of their powers (some do, though).
