In present work an Active Noise Control System (ANCS) mounted on the headrest of an aircraft’s seat is proposed. It is based on the non-linear FsLMS algorithm alongside with a linear extrapolation technique used to estimate the acoustic pressure around the passenger’s ears. In order to check system’s effectiveness, real-time experiments took place inside an aircraft’s cabin mock-up for an acoustic disturbance measured during the flight of a tilt-rotor aircraft. The results have shown a more than 10 dB attenuation of different BPF harmonics and a significant SPL reduction that varies from 8 dB to 11 dB around the passenger’s ears.
