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
In: Technology
To break it down at a general level:
1. Your voice makes the air vibrate.
2. The air makes a microphone vibrate.
3. The microphone turns the vibrations into electrical “vibrations”.
4. The phone interprets the electrical signal digitally. At this point, it’s sort of like an MP3 file.
5. The digital audio gets sent to the other phone.
6. The other phone plays it back just like a music file (and it’s almost exactly the inverse of steps 1-4!)
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.
