‘Ultrasonic espresso’ made with cold water and high-frequency sound waves uses less energy than the traditional version – and taste tests show it’s just as good.
According the the article, the espresso was rated equal to traditionally brewed. Ultrasound brewed filter coffee was rated as better than traditional.
Though it sounds like they were all cooled down since the ultrasonic brewing didn’t best the water. So that is also a factor. If you like hot coffee, this wouldn’t be a worthwhile brewing method.

Maybe a more effective cold brew then
Well, they apparently had already used ultrasound to speed up the cold brew process. This was a continuation of that research.
