Something Actually New/Innovative, In Audio

This technology has been around quite a while. It was going to be used for vending machines and museum tours. Hope it turns into something useful...

I think it's used in wifi. 

No specs, like frequency response or dynamic range, etc..?Count me add one as dubious of it’s high end applications. Remember glass speakers?

Remember the ENIAC?      Fast as technology is progressing, these days; vast improvements are inevitable, IF a market develops.

With dweller. Tech has been around for decades. Didn't read far enough to know if it is using distortion in the air or ear to modulate to audible frequencies. Says placed outside the ear so likely air.
