That reminded me. Where did the buzzing sound go. Remember when you had incomming call, your speakers would buzz?
It was like super power: "Someone's calling me" ... Ring Ring
4G is on a different frequency, it's out of the audible range.
The reason you used to hear it is that a speaker turns electromagnetic vibration, so the back and forth movement of electrons into mechanical vibration, so the back and forth movement of sound.
2G was on a frequency that you could hear, so when the wires in your speakers picked it up like an antenna, your speakers played it back. 4G is much higher pitched, so it's still there, it's just so high you can't hear it anymore.
Edit: Read Milkyway's comment, they sound like they know more about this than I do. It's not the frequency but the amplitude.
are you a wizard 😨
