Like …. I get the premise of the receiver and the sound is transmitted via radio waves…. But when you say it out loud??

We somehow trap our physical sound inside radio waves which you can’t physically see or touch and that transmits almost instantaneously and someone can then hear it ???

HOW

It’s frequencies! Sounds travel in waves and it’s a form of energy which some that is caught by the phone then transmits to the frequency that is on the other line. Kinda like the two cups with a string type deal. You can see it physically like that but basically it’s that without the hardware of linking your phones together. Radio stations have a one way of this type of things to get music to your car. That’s why when your in a tunnel or underground the waves get distorted and you can’t hear clearly.
