Question

How do acoustic headphones work?

Answer 1

Answer:

The technology, known as active noise-cancellation (ANC), works by using microphones to pick up low-frequency noise and neutralise it before it reaches the ear. The headset generates a sound that's phase-inverted by 180 degrees to the unwanted noise, resulting in the two sounds cancelling each other out.
