Reply to comment by GanondalfTheWhite in Eli5 How exactly does Noise cancellation work? That too in such small airbuds by Professional-Ad3441
There's a lot that goes into noise cancelling, they are not always doing everything in real time. There are specially designed and fully dedicated chips on the sound devices that do just one thing, noise cancelling. They recognize certain sounds and apply the noise cancelling beforehand, thus eliminating that time window. They've been trained on millions of hours of noise and have gotten really good at what they do. Power of data, indeed.

I didn't know noise canceling relied on machine learning. It doesn't need to and the older ones likely did not.
