Reply to comment by [deleted] in Eli5 How exactly does Noise cancellation work? That too in such small airbuds by Professional-Ad3441
Except you can’t cancel it completely because there is a processing delay to invert the sound waves being played. Because of this delay, instead of getting no sound waves, you get double the amount of waves into your ears. Noise canceling doesn’t prevent ear damage
