Abstract This article reviews current turbofan engine noise and engine noise reduction technology, specifically focusing on the engine technology of larger passenger jetliners which have entered into service within the last ten (10) years. Important factors in turbofan engine design from a community noise perspective and the sources of noise along with their relative importance are also presented. A review of different engine noise reduction technologies is presented, as well as an estimate of the technology’s readiness level. Finally, potential trade-offs, challenges, and future technology directions are outlined.
