Noise Reduction Technology refers to methods and devices designed to minimize unwanted ambient sounds. This technology is commonly used in various applications, including headphones, aircraft, and industrial machinery. It works by either blocking sound waves or using algorithms to cancel out noise, creating a quieter environment for users. There are two main types of noise reduction: passive and active. Passive noise reduction involves physical barriers, like padding or insulation, to block sound. In contrast, active noise reduction uses microphones and speakers to detect and counteract noise waves, effectively reducing the perception of sound in real-time.
