Abstract: PURPOSE: A helicopter intercom device equipped with a noise cancelling function and a method thereof are provided to remove noises mixed in an audio signal during internal communications between a pilot and a crew member, thereby enabling internal communications between the pilot and the crew member to be accurately performed. CONSTITUTION: A communications repeater (400) is connected with a user terminal. The communications repeater internally or externally relays the communications of a signal from the user terminal. A two-way radio (500) is connected with the communications repeater. The two-way radio transmits and receives a signal to and from the outside for the communications repeater. An external control center (100) is wirelessly connected with the two-way radio. The external control center transmits and receives a signal to and from the two-way radio.
