Acoustic performance is a characteristic of aircraft, relating the amenity of the civil aircraft during the grounding, the take off, the cruise and the landing. Own to the limitation of the reducing noise method, it爷s very important for aircraft designer that it need to be introduced the acoustic engineering into the aircraft design when the concept design process. It is an issue for studying and researching along time.Therefore, based on the above-mentioned situations, the paper overviewed the main cabin acoustic program of the large commercial aircraft.
