If I'm interpreting the image correctly, it looks like maybe this is closer to reactive armor, than it is to force fields?

If an explosive shockwave is simply a front of pressure differential traveling through air as it's medium, and thus effectively a very strong/coarse a sound wave, then it's subject to disruptive interference, right?

They don't claim to eliminate the shockwave, but only attenuate it. Based on that, it seems like an opposing shockwave of comparable force might dampen or lessen the front of the shockwave, by way of disruptive interference.

Otherwise, would maybe just introducing turbulence or loud randomized noise into the path of a shockwave manage to "attenuate" it?

It is possible that just the loud crack of an electrical arc would be enough to reduce the intensity of a blast wave?
