I thought about it for a few minutes longer and realized this can work because your wearing something right next to your eardrum. Before I was thinking how could sound be cancelled, if I yell at a concert when the band is playing my yell is still there but it’s drowned out, but I guess because the headphones are right next to your ears that must be a big part of why it works.

So say you have some good ones, when the headphones hear a noise and play the inverse to cancel it, can you hear that at all? Also, is there a delay? If there was a gunshot far enough away where the headphones could manage to cover the volume of the shot, would it be able to cancel it out in real time? I just don’t understand how sound can be cancelled without some sort of other sound that plays to replace/mask it, in which case it’s not cancelling it just lessening it.
