How does the microphone on a MacBook not cause feedback?

903 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)?

Devices “know” what audio is being outputted through their speaker and will how the sound from the speakers is picked up by the mic, and will cancel out the audio output from the device that the onboard mic picks up.
