Abstract
The pilot communication system employs an acoustic transducer disposed on the flight deck and positioned to emit sound waves in the direction of the at least one pilot seating location. A modulator circuit is coupled to receive an audio signal from the avionics communication system and is also coupled to drive the acoustic transducer. The modulator circuit supplies to the acoustic transducer an electrical signal having an ultrasonic carrier frequency modulated by the audio signal, thereby causing the acoustic transducer to deliver a beam of ultrasonic acoustic energy, through the acoustic space, in the direction of the at least one pilot seating location, which beam of ultrasonic acoustic energy is demodulated naturally by traversal through air molecules between the transducer and the pilot seating location, thus rendering the audio signal audible by human hearing at the at least one pilot seating location.
