It takes advantage of the fact that light and electrical fields travel about a million times faster than sound (300 million m/s versus 300 m/s). If you think about it, sound is extremely slow. Hearing echoes is a common occurrence and animals like bats even use it for navigation.

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