How does the microphone on a MacBook not cause feedback?

887 views

On a MacBook, I can be in a Zoom Meeting and speak into the MacBook Mic, while also listening to the meeting via the MacBook speakers. How is it possible for the mic to only receive my voice (and not also the sound of the meeting coming out of the speakers)?

the computer simply KNOWS that it is outputing so it just subtracts what it is outputing from what it is trying to input to the other person speaking to you

it’s like knowing that you’re already running towards something so instead of slapping the fuck out of their hand as you normally would while standing, you just hold your hand in the air and wait to run up next to them
