Noise-canceling technology is designed to reduce unwanted ambient sounds, making it easier to focus or enjoy music. This is especially useful in noisy environments like airplanes or busy streets. Noise-canceling headphones use microphones to pick up external sounds and then create sound waves that are the exact opposite, effectively canceling out the noise. There are two main types of noise-canceling: passive and active. Passive noise-canceling relies on physical barriers, like cushioned ear cups, to block sound. In contrast, active noise-canceling uses electronic components to detect and counteract noise. Together, these methods help create a more peaceful listening experience.
