The weird part, though, is that I can't find any articles about how such sounds might affect other things.

Like, what if a team of SCUBA divers had these high powered megawatt level infra-sound transducers aimed directly at them, and felt the brunt of such a wavefront at close range?

Would they even hear it, or maybe just feel it? Would they get a concussion? Would it shake them so violently that maybe they suffer massive full-body bruising, and even hemorrhaging or worse?

This is the part that seems unclear. How do these noises compare to something like the shockwave of a depth charge, in terms of energy imparted on other objects suspended in proximity? What happens to, oh I dunno, fine structured ballistics gel replicas of sensitive organs?
