ABSTRACT:
An active noise control system for aircraft includes a headset for use by a pilot of the aircraft. A plurality of sensors are mounted on the aircraft at predetermined locations to sense aircraft noise. The aircraft noise at each of the sensors has a first sound waveform in a first phase. A plurality of actuators are operatively connected to respective sensors and communicate with the headset. Each actuator generates a second sound waveform in a second phase. A controller commands each of the plurality of actuators, and dictates the second phase of the second sound waveform, such that the first and second sound waveforms interact out of phase in a manner sufficient to control the aircraft noise. The controlled aircraft noise enables auditory detection of remote environmental disturbances outside of the aircraft thereby enhancing pilot sensory awareness.
