Reply to comment by theperfectmuse in Eli5 How exactly does Noise cancellation work? That too in such small airbuds by Professional-Ad3441
Me either: I get the waves effect, personally, visually it makes sense and by the numbers it makes sense, but I really want to see it in action with sounds because it still doesn’t make sense from a “that’s how it works” perspective.

You can do it by playing low noises from two speakers set far apart and walking around between them.
The noise will be louder in some spots and quieter in others.

Fascinating. The same sound, I assume? Or different?
