They are getting rid of traditional radio antennas/systems and somehow using acoustic properties to transmit / receive?
Is it referring to these sorts of devices?Sounds like they are using an acoustic amplifier in place of an electronic amplifier to boost radio reception because it promises to be more energy efficient. No pun intended.

Yeah similar but hopefully without the bad repSo like bluetooth, but without the EMI considerations? Wonder how my dog will like it.
You are not meant to hear the sound waves, the freqs are way beyond our hearing. They will be received like a radio wave and converted to whatever was intended. It could be audio, data or signalling.
