Sound is a crappy way to transmit energy. Sound intensity is governed by the inverse square of the distance (exponential decay at range). Kinetic weapons are far more efficient, only losing energy to drag which is dependent on velocity and air density.

If you were to put the same amount of energy that's in the 160db emitters into steel fragments you'll have a much larger kill radius in a smaller package.

When it is not necessary to make a decision, it is necessary not to make a decision.
