Active Noise Control (ANC) is a technology designed to reduce unwanted sounds by using sound waves. It works by capturing the noise through microphones and then generating a new sound wave that is the exact opposite, or "anti-noise." When these two sound waves meet, they cancel each other out, resulting in a quieter environment. This technology is commonly found in headphones and aircraft to enhance comfort and reduce distractions. ANC is particularly effective in environments with consistent noise, like the hum of an airplane engine or the buzz of a busy street. By using this method, people can enjoy a more peaceful experience, whether they are listening to music, working, or simply relaxing.
