1. Noise-cancelling headphones refer to a headset that uses a certain method to reduce noise. At present, there are two kinds of noise cancelling headphones: active noise cancelling headphones and passive noise cancelling headphones.
2. The active noise reduction function is to neutralize the noise by generating reverse sound waves equal to the external noise through the noise reduction system, so as to achieve the effect of noise reduction. Passive noise-cancelling headphones mainly form a closed space by surrounding the ear, or use sound insulation materials such as silicone earplugs to block outside noise.
