This looks different from Cleveland Whiskey. Cleveland accelerates aging by use of high pressure [1].

The technique reported in the NPR article uses ultrasound, apparently at ordinary pressure. The original journal article (pdf) is open sourced at [2].

So to extrapolate: ultrasound under high pressure and age in 30 minutes.

I'm not sure they would go that well together; high pressure inhibits cavitation, I'm pretty sure, and cavitation is the primary mechanism by which the ultrasound method extracts the various compounds from the wood. Maybe if you used higher energy ultrasound?
