I don't see anything new here on top of what the skeptics have postulated.

In particular the 145-155db number does not look 100% safe for me. This is not going to burn your skin but you might end up hearing it anyway, feeling uncomfortable or who knows what. Various opinions about the safe level for ultrasound are in the 100db-120db range so you are talking like 300x the intensity.

Looks like Theranos 2.0.

Sure, it might be dangerous, but at least you wouldn't have to plug in your phone anymore.

I read that in Archer's voice.

And then there is the distinction between 'safe' and 'comfortable'. I have a pretty beefy ultrasonic cleaner here and the harmonics from that thing are what gets me, not the primary. It's definitely safe and yet I'm more than happy to move a door further away from it when it is running.
