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.
No, the frequency isn't necessarily all that different. Some 4G Bands are even below typical 2G/GSM Bands. The major difference is how the multiple access and Modulation is done. 2G uses short, narrowband, high power bursts. It's the interval of these bursts that causes the interference, not the carrier frequency.

I can still hear it.
Me too. I worked in a call center in the mid 2000s and you couldn’t hear yourself think for it. Everyone was told to turn them off but no one did. Every text, every call, the Razr made her call into the headsets.
Bloopadopp bloopadopp ...."Susan please..."
Thanks, TIL, edited my comment.
Wait, were our poor doggies being tortured by the constant sound of our 2g communications?
are you a wizard 😨

Buzzing? Couldn't you compensate by just delaying playback by one cycle?
