The intensivenoise of carrier-based aircraft is a serious threat to the healthof carrier deck staff and people in communitiessurrounding the naval base. Noise reduction is one of the key research projectsamong the technologies of carrier-based aircraft. Beginning with the noise problem of carrier-based aircraftand its effects and risks, this paper points out the core source of noise, engine jet noise, summaries the new advances of jet noise suppression technologies, and raises the idea that multiple methods ought to be comprehended to solve the noise problem of carrier-based aircraft.
