Active Noise Reduction for General Aviation Aircraft Using Conventional Headsets

Active Noise Reduction (ANR) headsets are quite efficient at reducing noise in a cabin of general aviation aircraft, however they are generally bulky, uncomfortable and expensive. If compromise is accepted in terms of achieved lower noise attenuation for passenger, acceptable noise reduction could be achieved using conventional headsets that are much more comfortable, better suitable for listening to the music and could be wireless. In this paper solutions are presented that use synchronized waveform generator where noise canceling waveform is dependent on engine rotational speed and seat position within a cabin of a single engine general aviation aircraft.
