How do noise-cancelling headphones work?

Can you explain how noise-cancelling headphones work?

Sure! Noise-cancelling headphones use microphones to pick up ambient sounds and then create sound waves that are the exact opposite, effectively cancelling out the noise.

So, do they work for all types of noise?

They are most effective at cancelling out consistent, low-frequency sounds like engine noise, but they may not be as effective for sudden, high-frequency sounds.

Are there different types of noise-cancelling technology?

Yes, there are two main types: passive noise cancellation, which blocks sound physically, and active noise cancellation, which uses electronic methods to reduce noise.

Can I use them while flying?

Absolutely! Noise-cancelling headphones are great for flights as they help reduce the sound of the airplane engines, making your experience more enjoyable.
