About this listen
They seem like magic: you put them on, and the drone of an airplane engine or the chatter of a busy office simply vanishes. But how do noise-cancelling headphones create silence? This episode demystifies the technology, explaining the clever physics of "destructive interference" and how your headphones create "anti-noise" to erase unwanted sound waves.
