Google Meet uses source separation technology to denoise the audio. It's a neural net that's been trained to separate speech from non-speech and ensure that only speech is being piped through. It can even separate different speakers from one another. This technology got really good around 2021 when semi-supervised ways of training the models were developed, and is still improving :)
