Reply to comment by jswansong in Eli5 How exactly does Noise cancellation work? That too in such small airbuds by Professional-Ad3441

Also active noise canceling does not block sound and can still cause hearing damage

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

I am aware of annihilation.

I suppose I should have worded differently. ANC will not stop you from getting hearing damage as opposed to something that blocks the sound like ear plugs and the like
