    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.

      Che_Che_Cole on reddit wrote three years ago this:

      simply that we don’t use TDMA anymore, time division multiple access. TDMA was a way for multiple users to share one channel (basically a radio frequency, not unlike a TV channel over the air or tuning your radio to a certain station). It did this by splitting up each user’s signal into short bursts of data. Those bursts/pulses of data are what you heard buzzing in your speaker.

      If you’re American you may have noticed back in those days, only Tmobile and ATT did this. They were GSM carriers who used TDMA. Verizon and Sprint used CDMA which was a different technology that did not cause the buzzing speaker because it didn’t transmit in pulses of data.

      Newer technologies don’t use TDMA either, so 3G, LTE, now 5G won’t cause a buzz. If you noticed the speaker buzz phenomenon started disappearing in the early 2010s (in the US), that’s why.

    I can press the volume down button and it’ll silence the incoming call. So I can go about my day.

    Leave a message after the b-

      Me too. It’s faster than texting and gives you a whole lot of missing context.

      One of the few actual good usages of ChatGPT

      How about calling them “Phone Trappers”?

      It sounds like something Jerry would say: “You know these people, the Phone Trappers. They ask you what you’re doing, and the second you say you’re free—bam!—they trap you into a call. It’s a trap! They lure you in with a text, then they pounce with the phone.”
