Active noise cancellation (anc) the active noise cancellation system implements the acoustically adaptive algorithm that cancels the unwanted sound by generating an antisound (antinoise) of equal amplitude and opposite phase. Practical design is based on the concept of a continuously operating microphone (or group of microphones) sampling the enviornment and a speaker (or group of speakers) producing interfering waves that will cancel the noise. Active noise cancellation (anc) is rapidly evolving as a technology area that enables car manufacturers to simultaneously differentiate their vehicles while enhancing the overall passenger experience.
