How Do Noise-Canceling Headphones Work?

Noise-canceling headphones use destructive interference to reduce ambient noise. They work by generating sound waves that cancel out external noise, creating a personal sound bubble. This technology is most effective against constant noises like airplane engines but struggles with sudden or variable sounds like a crying baby. While not eliminating all noise, it significantly reduces it, providing a quieter experience.
