"Also, by generating the Schumann Resonance, there is an effect that it neutralizes harmful standing waves."
This part of the explanation, I might add in fairness, might have a small grain of substance to it, though not much and actually the device could be making the standing wave problem worse. I recall a device called the Phantom Acoustics Shadow, which was an active device almost like a cylindrical subwoofer which was put into the corners of rooms to cancel (at least partially) standing waves. It used a pair of microphones that converted sound waves to electrical energy, phase inverted it, amplified the signal and sent it to transducers in the Shadow, which then produced an out-of-phase output at the excessive bass frequencies that cancelled or reduced the excess bass energy. That device, which according to Bob Harley's review was developed by Nelson Pass, had some science behind it, at least. If you're interested in it, see http://www.stereophile.com/roomtreatments/1289phantom/. This Acoustic Revive device does not state whether the signal it sends out is phase inverted, nor does it seem to address any frequencies other than the one mentioned (or, if you follow up with the Wickopedia article, certain others, but none of which may match the room's standing wave frequencies).
