perhaps tens of kilowatts of acoustic energy pumped in.

10s of kW sounds unlikely. Here are some examples of sound power:

Really, that’s your problem?

A good latin thump-mobile stereo from the hood can put out a few kilowatts of acoustic energy. I hear them blocks away.

Earthquakes put out acoustic energy on the order of hydrogen bombs.

You got a better theory?
