At some point the waves will have dispersed so much the sound vibrations would be smaller than the random motion of the air molecules. There would be no way to detect the original sound at that stage.

Reply to comment by SaishDawg in Physicists nail down the most precise value yet of the electron magnetic moment. A newly measured value of an electron’s magnetic moment — a property of its spin and charge — is twice as precise as the one physicists have used for the past 14 years. by MistWeaver80
Neither. The g-2 measurement is done with a muon, not an electron. Since any anomalies scale with mass squared, and the muon is 200 times heavier than an electron, that experiment is 40000 times more sensitive to new physics than this one. Doubling the electron measurement accuracy reveals nothing new.

Would such modulation techniques actually work? I’m mean EM waves aren’t exactly a 1:1 match to sound waves and the former doesn’t use a transport medium. I admit this isn’t my field but you have made me curious.
